201143935 六、發明說明： 【發明所屬之技術領域】 本發明係關於一種鑄坯導架段，其用於在一連續鑄造 機之鑄坯導架中支撐並導引一具有平板截面之金屬鑄坯。 具體而言，本發明係有關於一種用於在一連續鑄造機 之鑄坯導架中支撐並導引一具有平板截面之金屬鑄坯的鑄 坯導架段，其包括一頂架及一底架，其中頂架被可分離地 連接至底架；其中複數個鑄坯導輥各被連接至底架及底 架；及其中兩個被緊密連續地配置且可個別位移之鑄坯導 輥在鑄造方向上可被個別地坐定抵住鑄坯。 【先前技術】 DE 27 3 1 748案中揭示一種具有個別輥坐定之鑄坯導 架段，其中至少兩連續對之鑄坯導輥可被個別地（亦即彼此 獨立地）坐定抵住此鑄坯。在此方法中，兩移動裝置之一端 被連接至底架，而另一端則被連接至頂架，以致當拆卸一 可位移之鑄坯導輥時，必須手動地從頂架上拆離諸移動裝 置，並接著必須從底架上拆離頂架。除此之外’亦有必要 在拆離一不可位移之.禱坯導輥時，從底架上拆離底架。由 於在一連續鑄造設備之鑄坯導架中的受限空間狀況’所以 在鑄坯導架段處於已被安裝之狀態時將不可能更換個別之 鑄坯導輥，且這對於此鑄坯導架段之可用性及使用成本具 有不利之影響。 【發明内容】 本發明之目的在於提供—種在前言中所述及類型之鑄 201143935 坯導架段，其中當鑄坯導架段處於已被安裝狀態時，可分 離地更換此鑄坯導架段之至少一個（較佳係每一個）可個別 位移的鑄坯導輥。因此，可改善使用此鑄坯導架段之簡易 性。 此目的係藉一鑄坯導架段而達成，其中各可個別位移 之鑄坯導輥被分配一輥架，至少一可供在一與鑄造方向成 橫向之坐定方向上移動此輥架用之移動裝置，及精確地還 有一被配置爲與鑄造方向成橫向之十字頭，其中此十字頭 被可分離地連接至頂架或底架，其被連接至可個別位移之 鑄坯導輥上，其中移動裝置之一端被鉸接地安裝在十字頭 上，而另一端則被鉸接地安裝在輥架上，且此可個別位移 之鑄坯導輥被支撐成可轉動於輥架上。 在此情形中，各可個別位移之鑄坯導輥在一模組結構 中被分配一輥架、至少一移動裝置、及精確地還有一被配 置爲與鑄造方向成橫向之十字頭，如此將使這些組件可在 組裝或拆卸期間得以模組之型式供應至或移除自該鑄坯導 架段。 該十字頭本身被可分離地連接至機架（具體而言係指 頂架或底架），其被連接至該可個別位移之鑄坯導輥。此結 構使一可個別位移之鑄坯導輥（包含諸坐定裝置）能被非常 簡單且快速地安裝及拆卸，因爲，具體而言，其僅需要從 機架上將十字頭拆離，並接著從機架上連同此十字頭移去 諸移動裝置、輥架、及鑄坯導輥本身，如此使得一可個別 位移之鑄坯導輥甚至在當該導架段於鑄坯導架中係處於已 201143935 安裝狀態下，仍可被安裝或拆卸。 在一簡單之實施例中，一不可位移之鑄坯導輥沿坐定 方向被安置在與一可個別位移之鑄坯導輥相對立處。根據 此實施例，典型地，在弧形設備中之情形爲：底架之所有 鑄坯導輥（亦稱爲外側架）被分配給固定側，亦即這些鑄坯 導輥設計成不可位移之鑄坯導輥，而頂架之所有鑄坯導輥 (亦稱爲內側架）被分配給鬆開側，亦即這些鑄坯導輥被設 計成可個則位移之鑄坯導輥。 在一有利之實施例中，另一可個別位移之鑄坯導輥沿 坐定方向被安置在與一可個別位移之鑄坯導輥相對立處。 此情形典型地爲：頂架之所有鑄坯導輥及底架之所有鑄坯 導輥各被分配至一鬆開側，在此情形下，所有鑄坯導輥因 此設計成可個別位移之鑄坯導輥。此實施例具有一更複雜 之設計，但仍允許所有鑄坯導輥被個別地移去。除了所有 鑄坯導輥可被個別替換外，此實施例還有另一優點：所有 可位移鑄坯導輥均可被個別地坐定至鑄坯上，如此使得例 如一或多個鑄坯導輥之側向表面的過度轉動可輕易地藉由 一相關聯之直徑減小予以補償。 與上述兩實施例相關聯，「相對立」意指兩相對立之 鑄坯導輥在鑄坯之厚度方向上相對於彼此偏置，如果適 當’諸鑄坯導輥亦可在鑄造方向上成軸向偏置。 在一實施例中，被連接至該可個別位移之鑄坯導輥上 之頂架或底架係由兩側面支撐架及在各種情形下還有每一 可個別位移之鑄坯導輥的十字頭所構成，其中此側面支撐 201143935 架具有一用於每一可個別位移之鑄坯導輥之縱向導引裝 置，較佳係一縱向狹槽，其延伸在坐定方向上。 在一簡單之實施例中，輥架具有一板狀設計，其中此 輥架經由複數個導引件被導引於諸側面支撐架之縱向導引 裝置中，而此諸縱向導引裝置較佳地係縱向狹槽。此確保 可簡單地導引輥架並因此可導引鑄坯導輥，且此對於鑄坯 導輥之導引精確性方面具有正面之效果。 在另一實施例中，一鑄坯導輥被支撐在複數個軸承 上，例如在輥架上或在底架上，以致其在只有輕微撓曲發 生時，可從輥處轉移更高之支撐或坐定力。 在一有利之實施例中，各輥架被分配兩個移動裝置， 其中各移動裝置沿該可個別位移之鑄坯導輥之縱長方向被 鉸接地安裝在位於諸輥架上之兩最外側軸承內。此實施例 首先可在右手邊及左手邊上預先界定不同之坐定位置或坐 定力；另一方面，諸支撐力或諸坐定力從輥架處被有利地 引入諸移動裝置中。此外，藉此可確保右手邊及左手邊上 之輥夾點在每一情形下均相對應於一（相同或不同）坐定點 値。 然而，兩移動裝置自然地亦可沿該可個別位移之鑄坯 導輥之縱長方向被鉸接地安裝在位於諸輥架上之兩最外側 軸承內。 此外’各輥架在一實施例中亦可被分配一居中配置在 該輥架上之移動裝置。 在一有利實施例中，一個十字頭經由一較佳係以液壓 201143935 促動之各自的鉗緊裝置而被連接至一側面支撐架，藉此可 減少更換一個十字頭所需要之時間。 在一有利實施例中，一鉗緊裝置被分配一自動式介質 供應器’其中此供應器在十字頭被連接至該側面支撐架或 該等側面支撐架時，會自動連接，藉此將可自動地（亦即， 不需手動干預）連接及分離諸介質供應管線，以致可進一步 減少更換一個十字頭所需要之時間。 在一實施例中，一移動裝置設計成一壓力介質型汽缸。 有利地’一移動裝置被分配一用於測量坐定位置之位 移測量裝置及/或一用於測量坐定力之力測量裝置。 在一簡單，堅固且精確之實施例中，該力測量裝置設 計成一可供測量一壓力介質型汽缸之至少一液壓室的壓力 用裝置。 如果一控制裝置連接至一力測量裝置、一位移測量裝 置（較佳被整合於一液壓汽缸中）及一促動裝置（較佳係一液 壓比例閥或伺服閥），例如以便補償因移動裝置之坐定力所 致之十字頭撓曲，則可高精確地獲得所要之坐定力或所要 之鑄坯厚度。在此情形中，由力測量裝置所確定之坐定力 被用來實現該十字頭及/或另外組件之撓曲的轉變，以致該 十字頭及/或另外組件之撓曲可藉控制裝置經針對坐定位 置之已標定坐定點値之修正而補償。 在另一實施例中，一輥架被分配至少一用於校準一位 移測量裝置之止動器。藉此可在由十字頭、移動裝置、輕 架及鑄坯導輥所組成之模組安裝在鑄坯導架段之前，先校 201143935 準此模組，並因此如果移動裝置在某一時間點移動抵住止 動器，則可使用此已被完全校準好之模組，因此，具有完 全可用性。 有利的是在一連續鑄造設備中使用根據本發明所實施 之鑄坯導架段，而該連續鑄造設備包括拱形或水平鑄坯導 架，用來由鋼生產較佳地具有一平板或薄板截面之鑄坯。 然而，本發明自然地亦可用於垂直設備中或於初軋設備中。 本發明之另外優點及特徵由以下參照附圖之說明及非 限定性之示範實施例，將可瞭然。 【實施方式】 第1圖顯示一用於由鋼生產扁鋼坯之弧形連續鑄造機 的鑄坯導架段1。在此連續鑄造機本身中，熔融鋼液被鑄 造於一鑄模中，以形成一至少已部份固化之鑄坯，其進一 步被導引、支撐並冷卻於下游之拱形鑄坯導架中，而此導 架係由複數個在鑄造方向2上被連續地配置之鑄坯導架段 所構成。此鑄坯導架段1包括一頂架3及一被可分離地連 接至此頂架上之底架4，其中被分配給頂架3之所有鑄坯 導輥5設計成可被個別地坐定之可位移鑄坯導輥6，而所 有被分配給底架4之鑄坯導輥5則設計成不可位移之鑄坯 導輥7。諸可個別地坐定至鑄坯上之可位移鑄坯導輥6可 用來使此鑄坯接受以標定方式所進行之冶金處理（諸如輕 壓或預輥軋等），如此將會導致例如： - 每一個可位移之鑄坯導輥6的坐定力可保持在預設之 限度內以便改善內在品質；然而，其亦可能因此而得 201143935 以防止此可位移鑄坯導輥之超載； - 此鑄坯之液相線頂端可藉由觀察諸可位移鑄坯導輥6 之坐定力而被高精確地確定； - 可在厚度上達成任何想要（亦即線性，但也可爲非線性） 之減小’此厚度係相對於該鑄坯之鑄造方向2成橫向 者。 底架4經由多根側面連接柱25被連接至頂架3，其中 頂架3係由兩側面支撐架12及每一可位移鑄坯導輥6之各 自十字頭11所構成。每一可位移鑄坯導輥6被分配—模 組，其包括：一板狀輥架8;兩移動裝置9，其設計成可供 在相對於鑄造方向2成橫向之坐定方向10上，移動此板狀 輥架8用之壓力介質型汽缸17;及一個十字頭11，其藉由 多個以液壓方式預加應力之鉗緊裝置而被可分離地連接至 側面支撐架12。每一鑄坯導輥6係由四個軸承15所支撐， 以致其可在輥架8上轉動，並因此甚至可在僅有小撓曲下 引入更高之坐定力至輥架中，且結果進一步引入頂架3 中。壓力介質型汽缸17之一端被鉸接地安裝在十字頭11 上，且其另一端被鉸接地安裝在輥架8上，其中各壓力介 質型汽缸17沿著可位移鑄坯導輥6之縱向長度方向被鉸接 地安裝在兩個位於輥架8上的最外側軸承1 5內。此模組結 構將使一可個別位移導輥6(包括被分配到之輥架8、諸移 動裝置9與十字頭11)甚至在鑄坯導架段1處於已安裝狀態 時，仍可被拆卸或安裝，因此，可輕易進行維修工作。因 爲各輥架8被分配一止動器22,所以也可甚至在已被拆卸 -10- 201143935 之狀態下，校準此模組’亦即在鑄坯導架段之外部，而一 旦已經到達一參考位置（例如當已移動抵住止動器22或十 字頭1 1時），則在此將可用一被分配給壓力介質型汽缸1 7 且已被完全校準好之位移測量裝置。或者，校準也可在鑄 坯導架段之外部進行。此外，多個鉗緊裝置16被分配一自 動式介質供應器2 4，以便當十字頭1 1連接至一側面支撐 架1 2時，諸介質供應管線（例如液壓、冷卻劑及/或壓縮空 氣管線）亦被同時連接。至少一導引件1 4用以在各側面支 撐架12之一縱向導引裝置（被設計成一縱向狹槽13)中導引 各板狀輥架8，且此提供一高導引精確度及剛性。 第2圖係一顯示第1圖中之鑄坯導架段1的前視圖， 其中亦同樣地顯示設計成水及/或水/空氣噴嘴之冷卻噴嘴 23 〇 第3圖顯示一根據本發明所實施之鑄坯導架段1之實 施例，其中所有鑄坯導輥5 (亦即被連接至頂架3以及底架 4上之諸鑄坯導輥）均設計成可個別位移之鑄坯導輥6。頂 架3藉複數個橫向配置之連接柱25而被可分離地連接至底 架4上’而頂架與底架各由兩個側面支撐柱12與各鑄坯導 輥6之各自十字頭所構成。除了可防止所有可位移鑄坯導 輥6超載外’此實施例還有下列優點：所有可位移鑄坯導 輥6可被個別地坐定至鑄坯上，並因此例如當一個別之鑄 坯導輥在服務工作期間已被過度地轉動至相當小之輥直徑 時，此在直徑上之減小可輕易地藉由改變移動裝置9之坐 定點位置補償。 -11 -

Description of the Invention: [Technical Field] The present invention relates to a slab guide frame for supporting and guiding a metal slab having a flat section in a slab guide of a continuous casting machine . More particularly, the present invention relates to a slab guide segment for supporting and guiding a metal slab having a flat section in a slab guide of a continuous casting machine, comprising a top frame and a bottom a frame, wherein the top frame is detachably coupled to the chassis; wherein the plurality of slab guide rollers are each coupled to the chassis and the chassis; and two of the slab guide rollers that are closely and continuously disposed and individually displaceable are The casting direction can be individually seated against the casting blank. [Prior Art] DE 27 3 1 748 discloses a strand guide segment having individual rolls, wherein at least two consecutive pairs of strand guide rolls can be individually (i.e., independently of each other) seated against this Slab. In this method, one end of the two moving devices is coupled to the chassis and the other end is coupled to the top frame such that when disassembling a displaceable slab guide roller, the movement must be manually detached from the top frame The device, and then the top frame must be detached from the chassis. In addition to this, it is also necessary to detach the chassis from the chassis when detaching the undisplaceable prayer roller. Due to the confined space condition in the strand guide of a continuous casting apparatus, it will not be possible to replace individual strand guide rolls when the strand guide section is in the installed state, and this is for the strand guide The availability and cost of use of the shelf have an adverse effect. SUMMARY OF THE INVENTION It is an object of the present invention to provide a casting guide segment of the type 201143935 described and described in the introduction, wherein the slab guide is detachably replaceable when the slab guide segment is in the installed state At least one (preferably each) of the segments may be individually displaced casting guide rolls. Therefore, the ease of using the slab guide section can be improved. This object is achieved by a slab guide segment in which each individually slidable slab guide roller is assigned a roll frame, at least one of which is adapted to move the roller frame in a direction of orientation transverse to the direction of casting. The moving device, and precisely also a crosshead configured to be transverse to the casting direction, wherein the crosshead is detachably coupled to the top frame or chassis, which is coupled to the individually steerable casting rolls Wherein one end of the mobile device is hingedly mounted on the crosshead and the other end is hingedly mounted on the roller frame, and the individually displaceable casting guide rollers are supported for rotation on the roller frame. In this case, each individually slidable strand guide roller is assigned a roll frame, at least one moving device, and precisely a crosshead configured to be transverse to the casting direction in a modular configuration, such that These components can be supplied or removed from the slab guide segments during assembly or disassembly. The crosshead itself is detachably coupled to the frame (specifically, the top frame or chassis) that is coupled to the individually slidable strand guide rolls. This structure enables an individually displaceable casting blank guide roll (including the seating devices) to be mounted and disassembled very simply and quickly, since, in particular, it only requires the crosshead to be detached from the frame, and The moving device, the roller frame, and the slab guide roller itself are then removed from the frame along with the crosshead such that a individually steerable slab guide roller is even in the slab guide when the guide segment is in the slab guide It can still be installed or removed in the installed state of 201143935. In a simple embodiment, an undisplaceable slab guide roll is positioned in a sitting orientation opposite a individually steerable slab guide roll. According to this embodiment, typically in the case of a curved device, all of the slab guide rolls (also referred to as outer shelves) of the chassis are assigned to the fixed side, ie the slab guide rolls are designed to be non-displaceable. The slab guide rolls, and all of the slab guide rolls (also known as the inner side frames) of the top frame are assigned to the release side, i.e., the slab guide rolls are designed to be a slopable slab guide roll. In an advantageous embodiment, another individually slidable strand guide roller is positioned in a sitting orientation opposite the individually slidable strand guide roller. This is typically the case where all of the slab guide rolls of the top frame and all of the slab guide rolls of the undercarriage are each assigned to a loose side, in which case all of the slab guide rolls are designed to be individually displaceable. Blank guide roller. This embodiment has a more complicated design, but still allows all of the strand guide rolls to be individually removed. In addition to the fact that all of the strand guide rolls can be individually replaced, this embodiment has the further advantage that all of the displaceable strand guide rolls can be individually seated onto the strand so that, for example, one or more strands are guided Excessive rotation of the lateral surface of the roller can be easily compensated for by an associated reduction in diameter. In connection with the above two embodiments, "opposing" means that the two opposite slab guide rolls are offset relative to each other in the thickness direction of the slab, if appropriate, the slab guide rolls can also be formed in the casting direction. Axial offset. In one embodiment, the top frame or chassis attached to the individually displaceable casting blank guide rolls are supported by two side support frames and, in each case, each individually slidable casting blank guide roll. The head is constructed wherein the side support 201143935 has a longitudinal guide for each individually displaceable casting guide roll, preferably a longitudinal slot extending in the orientation direction. In a simple embodiment, the roller frame has a plate-like design, wherein the roller frame is guided to the longitudinal guides of the side support frames via a plurality of guide members, and the longitudinal guides are preferably Vertical longitudinal slot. This ensures that the roll stand can be guided simply and thus the strand guide rolls can be guided, and this has a positive effect on the guiding accuracy of the strand guide rolls. In another embodiment, a strand guide roller is supported on a plurality of bearings, such as on a roller frame or on a chassis, such that it can transfer a higher support from the roller when only slight deflection occurs. Or sit down. In an advantageous embodiment, each roller frame is assigned two moving devices, wherein each moving device is hingedly mounted on the two outermost sides of the roller frames along the longitudinal direction of the individually displaceable casting blank guide rollers Inside the bearing. This embodiment can first define different seating positions or seating forces on the right hand side and the left hand side; on the other hand, the supporting forces or seating forces are advantageously introduced into the moving devices from the roll stand. In addition, it is ensured that the roller grips on the right hand side and the left hand side correspond to one (same or different) sitting point 每一 in each case. However, the two moving means can naturally also be hingedly mounted in the longitudinal direction of the individually steerable blank guide rolls in the two outermost bearings on the roll stands. Further, in each embodiment, each of the roller frames may be assigned a moving device centrally disposed on the roller frame. In an advantageous embodiment, a crosshead is coupled to a side support frame via a respective clamping device that is preferably actuated by hydraulic pressure 201143935, thereby reducing the time required to replace a crosshead. In an advantageous embodiment, a clamping device is assigned an automatic media supply 'where the supply is automatically connected when the crosshead is attached to the side support or the side supports, whereby The media supply lines are connected and separated automatically (i.e., without manual intervention) so that the time required to replace a crosshead can be further reduced. In one embodiment, a mobile device is designed as a pressure medium type cylinder. Advantageously, a mobile device is assigned a displacement measuring device for measuring the sitting position and/or a force measuring device for measuring the sitting force. In a simple, robust and precise embodiment, the force measuring device is designed as a pressure device for measuring at least one hydraulic chamber of a pressure medium type cylinder. If a control device is connected to a force measuring device, a displacement measuring device (preferably integrated in a hydraulic cylinder) and an actuating device (preferably a hydraulic proportional valve or servo valve), for example to compensate for the moving device By sitting on the deflection of the crosshead caused by the constant force, the desired seating force or the desired thickness of the slab can be obtained with high precision. In this case, the seating force determined by the force measuring device is used to effect a deflection of the crosshead and/or the other component so that the flexing of the crosshead and/or the additional component can be controlled by the control device. Compensated for the correction of the fixed position of the seated position. In another embodiment, a roll stand is assigned at least one stop for calibrating the one-position measuring device. In this way, before the slab guide section is installed by the module consisting of the crosshead, the moving device, the light frame and the slab guide roller, the module 201143935 is approved, and therefore if the mobile device is at a certain point in time Moving against the stopper allows the fully calibrated module to be used, thus providing full availability. It is advantageous to use a slab guide segment implemented in accordance with the present invention in a continuous casting apparatus, the continuous casting apparatus comprising an arched or horizontal slab guide for producing from steel preferably having a flat plate or sheet Slab of section. However, the invention can naturally also be used in vertical equipment or in rolling mill equipment. Additional advantages and features of the invention will be apparent from the description and accompanying drawings. [Embodiment] Fig. 1 shows a slab guide section 1 for a curved continuous casting machine for producing slabs from steel. In the continuous casting machine itself, the molten steel is cast in a mold to form an at least partially solidified strand which is further guided, supported and cooled in the downstream arched blank guide. The guide frame is formed by a plurality of strand guide segments that are continuously arranged in the casting direction 2. The slab guide section 1 includes a top frame 3 and a chassis 4 detachably coupled to the top frame, wherein all of the slab guide rolls 5 assigned to the top frame 3 are designed to be individually seated The cast strand guide rolls 6 are displaceable, and all of the strand guide rolls 5 assigned to the underframe 4 are designed as non-displaceable strand guide rolls 7. Displaceable slab guide rolls 6 which can be individually seated onto the slab can be used to subject the slab to metallurgical processing (such as light pressing or pre-rolling, etc.) in a calibrated manner, which will result in, for example: - the seating force of each of the displaceable slab guide rolls 6 can be kept within preset limits to improve the intrinsic quality; however, it may also result in 201143935 to prevent overloading of the displaceable slab guide rolls; The liquidus tip of the slab can be determined with high precision by observing the seating force of the displaceable slab guide rolls 6; - any desired (ie linear, but also non-linear) can be achieved in thickness Reduction of linearity 'This thickness is transverse to the casting direction 2 of the slab. The chassis 4 is connected to the top frame 3 via a plurality of side connecting posts 25, wherein the top frame 3 is formed by two side support frames 12 and each of the crossheads 11 of each of the displaceable casting rolls. Each of the displaceable strand guide rolls 6 is assigned a module comprising: a plate-shaped roll stand 8; two moving means 9 designed to be placed in a transverse direction 10 relative to the casting direction 2, The pressure medium type cylinder 17 for moving the plate-shaped roller frame 8; and a crosshead 11 detachably coupled to the side support frame 12 by a plurality of hydraulically pre-stressed clamping devices. Each of the strand guide rolls 6 is supported by four bearings 15 so that it can rotate on the roll stand 8, and thus even a higher seating force can be introduced into the roll stand with only a small deflection, and The result is further introduced into the top frame 3. One end of the pressure medium type cylinder 17 is hingedly mounted on the crosshead 11, and the other end thereof is hingedly mounted on the roller frame 8, wherein each pressure medium type cylinder 17 is along the longitudinal length of the displaceable casting guide roller 6. The direction is hingedly mounted in two outermost bearings 15 located on the roller frame 8. The modular structure will enable an individually displaceable guide roller 6 (including the roller frame 8, the moving device 9 and the crosshead 11 to be dispensed) to be removed even when the strand guide segment 1 is in the installed state. Or installation, so repair work can be done easily. Since each roller frame 8 is assigned a stopper 22, it is also possible to calibrate the module 'on the outside of the slab guide section even in the state where it has been dismantled - -10-201143935, and once it has reached one The reference position (e.g., when it has moved against the stop 22 or the crosshead 11), a displacement measuring device assigned to the pressure medium type cylinder 1 7 and fully calibrated will be available. Alternatively, the calibration can also be performed outside of the blank guide section. In addition, a plurality of clamping devices 16 are assigned an automatic media supply 24 such as a supply line (eg, hydraulic, coolant, and/or compressed air) when the crosshead 11 is coupled to a side support frame 12. The pipeline) is also connected at the same time. At least one guiding member 14 is used to guide each of the plate-shaped roller frames 8 in a longitudinal guiding device (designed as a longitudinal slot 13) of each of the side support frames 12, and this provides a high guiding accuracy and rigidity. Figure 2 is a front elevational view showing the slab guide section 1 of Figure 1, wherein the cooling nozzles 23 designed as water and/or water/air nozzles are similarly shown. Figure 3 shows a diagram in accordance with the present invention. An embodiment of the cast slab guide section 1 in which all of the slab guide rolls 5 (i.e., the slab guide rolls that are attached to the top frame 3 and the underframe 4) are designed to be individually slidable Roller 6. The top frame 3 is detachably connected to the chassis 4 by a plurality of laterally disposed connecting posts 25, and the top frame and the bottom frame are respectively supported by two side support columns 12 and respective crossheads of the respective casting guide rollers 6. Composition. In addition to preventing all of the displaceable slab guide rolls 6 from being overloaded, this embodiment has the following advantages: all of the displaceable slab guide rolls 6 can be individually seated onto the slab and thus, for example, as a separate slab When the guide roller has been excessively rotated to a relatively small roller diameter during service operation, this reduction in diameter can be easily compensated by changing the sitting position of the mobile device 9. -11 - 201143935 Figure 4 shows a detail of the slab guide section 1 containing the control unit 18. In this case, the control device 18 is connected to a displacement measuring device 20 and a force measuring device 19, which are designed as a mobile device 9 of a pressure medium type cylinder 17, and the control device 18 is used here to compensate for the crosshead. 11 Deflection due to the sitting force of the mobile device 9. Specifically, the force measuring device 19 supplies the actual enthalpy of the sitting force FAet, which is converted into the deflection AS of the crosshead 11 via the mechanical mode incorporated in the control device 18, and if appropriate, is also converted into The deflection AS of the other components (for example, the roller frame 8, the side support frame 2, the connecting column 25). The AS is then applied to the sitting fixed position SSet which has been pre-defined to the control unit 18, and this is controlled by the sitting position of the sitting position § § = SSet + AS. During control, a conventional method is used to compare the actual 値SAet of the § and the fixed point, and a control law is taken into consideration to determine an operational variable u designed to be hydraulically operated and supplied to the actuating device 21 so that SAet is as accurate as §値 as accurately as possible. Specifically, the following program steps are performed during the compensation of the sitting position due to the sitting force of a displaceable casting guide roller: - at least one actual 値 SAet of the sitting position by a displacement measuring device 20 Detected; - at least the actual force of the sitting force is detected by the force measuring device 19, and the displacement measuring device 20 of the moving device 9 and the force measuring device 19 are assigned to a displaceable casting guide Roller 6; - sitting position 値 sSet in sitting position, actual 値 sAet in sitting position and actual 値 FAet of sitting force are supplied to - control device 1 8 ; - take a mechanical model into consideration (for example, Liang Zhi Deflection), determine the sitting position -12- 201143935 position of the fixed point 値 due to the sitting force caused by the deviation (such as the cross head 1 1 deflection) AS; ' - calculate the sitting position of the compensated sitting 値 s = SSet+ AS; - by means of a control law, taking into account the actual 値SAet of the compensated sitting position S of the sitting position and the sitting position, determining the operational variable u; and - the operational variable u is Supplyed to an actuator 21 that is assigned to the mobile device 9 to The actual 値SAet of the sitting position is equivalent to the compensated sitting position of the sitting position as much as possible.
