Description
技術分野
本発明は熱間圧延設備に関し、特に移動式熱間コイル保温熱処理装置に関する。
Technical Field The present invention relates to a hot rolling apparatus, and particularly to a mobile hot coil thermal insulation heat treatment apparatus.
背景技術
冷間圧延超高強度鋼の生産には、主に帯鋼の長手方向及び幅方向に性能のばらつきが大きいという難題が存在し、冷間圧延生産の際に圧延力の急激な変動が生じることや、冷間圧延製品の厚さが公差標準を超えることに繋がり、これは、冷間圧延酸洗連続圧延機群の圧延安定性に影響を与えるし、冷間圧延超高強度鋼の歩留まりにもひどく影響を与える。
Background technology The production of cold-rolled ultra-high-strength steel has the problem that the performance varies greatly mainly in the longitudinal and width directions of the strip steel, and sudden fluctuations in rolling force occur during cold-rolled production. This leads to the occurrence and the thickness of cold-rolled products exceeding the tolerance standard, which affects the rolling stability of the cold-rolled pickling continuous rolling mills and of cold-rolled ultra-high-strength steels. It also has a terrible effect on yield.
伝統の熱間圧延生産ラインでは、巻取り終了後の鋼コイルの輸送において、鋼コイルの輸送しか完成せず、鋼コイルに保温徐冷、焼鈍等の処理プロセスが必要であると、専用の保温ピット、保温炉、ベル型炉、熱処理等の生産ラインを設置する必要がある。投資が大きく、エネルギー消費が高く、輸送コストが大きく、歩留まりが低い等の特徴を有する。特に高強度鋼種の場合、上記プロセスは時効の原因で、プロセス効果が理想の状態に達することができない。 In the traditional hot rolling production line, in the transportation of steel coils after winding, only the transportation of steel coils is completed, and if the steel coils require heat treatment such as slow cooling and annealing, dedicated heat retention is required. It is necessary to install production lines for pits, thermal insulation furnaces, bell-shaped furnaces, heat treatment, etc. It has features such as large investment, high energy consumption, high transportation cost, and low yield. Especially in the case of high-strength steel grade, the above process cannot reach the ideal state due to aging.
現在、国内外の主流製鋼所では、オフライン保温ピット、保温ウォール又は保温炉によって高強度鋼に徐冷、焼鈍処理を行い、帯鋼をコイルにしてからさらに均一に冷却させ、性能ばらつきの改善及び内部応力の緩和の目的を果たす場合が多い。現段階で、ある会社は移動式熱間コイル焼鈍制御装置について段階的に開発・応用を行っているが、使用過程において多くの問題がある。 Currently, in mainstream steel mills in Japan and overseas, high-strength steel is slowly cooled and annealed by an offline heat insulation pit, heat insulation wall or heat insulation furnace, and the steel strip is coiled and then cooled more uniformly to improve performance variation. Often serves the purpose of relaxing internal stress. At this stage, a company is gradually developing and applying a mobile hot coil annealing controller, but there are many problems in the process of use.
（１）圧延ライン保温装置に存在する最重要問題は、帯鋼が巻取ってから保温装置に入るまでの時間間隔が長すぎて、帯鋼の金属組織変態が殆ど発生若しくは完成したゆえ、オフライン徐冷による熱間コイル性能改善効果は、高強度鋼の品質要求を満たすことができない。熱間コイルを保温カバーに入れるには、２０〜３０分間吊ったままで輸送する必要があり、鋼コイルの空冷時間が長すぎて、保温効果と材料性能に影響を与える。 (1) The most important problem existing in the rolling line heat insulating device is that the time interval from winding the steel strip to entering the heat insulating device is too long, and the metallographic deformation of the steel strip is almost generated or completed, so that it is offline. The effect of improving hot coil performance by slow cooling cannot meet the quality requirements of high-strength steel. In order to put the hot coil in the heat insulating cover, it is necessary to carry it while hanging it for 20 to 30 minutes, and the air cooling time of the steel coil is too long, which affects the heat insulating effect and the material performance.
（２）このような保温装置には、専用の保温ピット、保温炉、ベル型炉、熱処理等の生産ラインが追加して設置され、構築コストが通常高くなり、しかも改造過程の工事期間が長くて順調な生産に影響を与える。また、保温効果が劣る（温度降下速度が速い）という問題も存在する。 (2) A production line for a dedicated heat insulation pit, heat insulation furnace, bell-shaped furnace, heat treatment, etc. is additionally installed in such a heat insulation device, and the construction cost is usually high, and the construction period of the remodeling process is long. Affects smooth production. There is also a problem that the heat retention effect is inferior (the temperature drop rate is fast).
（３）このような形態の保温カバーは殆どオフラインモード（保温装置が巻取り置き場に静止的に放置されるもの）であり、鋼コイルの吊り輸送で、生産ラインの正常な生産ペースが乱れる。圧延鋼生産ラインの生産能力の発揮が影響され、実際の量産化が困難になる。 (3) This type of heat insulating cover is almost in the offline mode (the heat insulating device is statically left in the winding place), and the suspension transportation of the steel coil disturbs the normal production pace of the production line. The actual production capacity will be affected by the production capacity of the rolled steel production line, making it difficult to mass-produce.
（４）現段階で、ある会社が開発した保温カバーは、形式上で保温効果しか持たず、底部構造が完全に密封できないゆえ、鋼コイル保温効果が劣る。 (4) At this stage, the heat insulating cover developed by a certain company has only a heat insulating effect in form, and the bottom structure cannot be completely sealed, so that the heat insulating effect of the steel coil is inferior.
中国特許ＣＮ２０１２１０３３８３３５では、鋼コイルの巻取り終了後にコイルを装荷して輸送する輸送チェイントレーを含む「ローラートレー式金属帯コイル輸送装置」が開示される。該装置は、単独で鋼コイルを輸送する固定台座だけである。輸送途中で鋼コイルにインライン保温を行うことができない。 The Chinese patent CN201210338335 discloses a "roller tray type metal strip coil transport device" including a transport chain tray that loads and transports the coil after the winding of the steel coil is completed. The device is only a fixed pedestal that transports the steel coil alone. In-line heat insulation cannot be performed on the steel coil during transportation.
中国特許ＣＮ２０１７１０８５３６１３．３では、保温効果しか持たず、底部構造が完全に密封できないゆえ、鋼コイル保温効果が劣る「インライン保温徐冷装置」が開示される。 The Chinese patent CN201710853613.3. Discloses an "in-line heat-retaining slow-cooling device" in which the steel coil heat-retaining effect is inferior because it has only a heat-retaining effect and the bottom structure cannot be completely sealed.
日本特許ＪＰ１９８５１１０８１６（Ａ）では、単一式保温カバーを含む「単一式保温カバー」が開示されるが、ローラーハース輸送チェインの構造形式を取り、鋼コイル保温作用しか奏することができない。 Japanese Patent JP 1985110816 (A) discloses a "single heat insulating cover" including a single heat insulating cover, but it takes the structural form of a roller hearth transport chain and can only exert a steel coil heat insulating action.
日本特許ＪＰ２０１００９４７１０（Ａ）では、専用の保温ピット等の生産ラインが追加して設置されたことを含む「トンネル式保温カバー」が開示されるが、構築コストが通常高くなり、しかも改造過程の工事期間が長くて順調な生産に影響を与える。 The Japanese patent JP2010917710 (A) discloses a "tunnel-type heat insulation cover" that includes the addition of a production line such as a dedicated heat insulation pit, but the construction cost is usually high, and the construction work in the remodeling process It has a long period and affects the smooth production.

前記側面密封装置は主に、密封性能を増強し、保温カバーがトレーに取り付けられる場合の内部保温空間での熱損失を防ぐためのものであり、密封性能が増強されると、密封空間内での鋼コイル残留熱の利用は向上する。 The side sealing device is mainly for enhancing the sealing performance and preventing heat loss in the internal heat insulating space when the heat insulating cover is attached to the tray, and when the sealing performance is enhanced, in the sealed space. Utilization of residual heat from steel coils is improved.
保温装置内の熱損失を低減させ、温度保温の安定性を向上させ、計測時のデータの正確性を保証し、保温装置の気密性を確保し、内部物体の酸化を防止し、作動自動化レベルを上げることで、鋼コイルの性能効果を高める。 Reduces heat loss in the insulation device, improves the stability of temperature insulation, guarantees the accuracy of data at the time of measurement, ensures the airtightness of the insulation device, prevents oxidation of internal objects, and the level of operation automation. By raising it, the performance effect of the steel coil is enhanced.
底部の開口が底部密封装置によって閉じ込められ、鋼コイルが巻取り機キャビティからトレーに取り出される時、保温物体が位置についてから保温カバーを被せ、走行過程において、該装置は自動的に横に移動し、トレー底部の開口を良好に密封し、密閉空間を形成し、温度が降下しないように保証し、保温を実現する。 When the bottom opening is confined by a bottom seal and the steel coil is removed from the winder cavity into the tray, the heat insulating object is covered from its position and covered with a heat insulating cover, which automatically moves sideways during the running process. The opening at the bottom of the tray is well sealed, a closed space is formed, the temperature does not drop, and heat retention is achieved.
輸送チェイントレーの保温カバーベースは、輸送チェイントレーの上部にあり、輸送チェイントレーに全体的に溶接される。保温カバーに対する荷重負担能力を向上させるために、輸送チェイントレーの保温カバーベースには、高強度耐熱鋼材を採用し、外部を保温材で被覆し、中間部をアンカー釘によって固定した後、最外部に耐高温ステンレス板を敷く。保温カバーを便利に上下に吊ることを保証するために、輸送チェイントレーの保温カバーベースの中間部に位置決めピンを設け、ガイドブッシュを設け、吊り・実装過程において、保温カバーを最終に位置につけ、位置決めの精度を高め、実装時間を向上させる。 The thermal insulation cover base of the transport chain tray is located on top of the transport chain tray and is entirely welded to the transport chain tray. In order to improve the load bearing capacity of the heat insulating cover, high-strength heat-resistant steel is used for the heat insulating cover base of the transport chain tray, the outside is covered with heat insulating material, the middle part is fixed with anchor nails, and then the outermost part. Lay a high temperature resistant stainless steel plate on the floor. In order to ensure that the heat insulation cover is conveniently hung up and down, a positioning pin is provided in the middle of the heat insulation cover base of the transport chain tray, a guide bush is provided, and the heat insulation cover is finally placed in the position during the hanging and mounting process. Improves positioning accuracy and improves mounting time.
鋼コイルが巻取り機キャビティからトレーに取り出される時、保温カバーは位置決めピンと位置決めブッシュによって密閉に位置を決めることにより、保温カバーを迅速に取り付けて位置を決めて密閉空間を形成し、温度が降下しないように保証することができる。 When the steel coil is removed from the winder cavity into the tray, the insulation cover is hermetically positioned by positioning pins and bushing to quickly install and position the insulation cover to form an enclosed space and the temperature drops. Can be guaranteed not to.
ガス保護装置は、鋼コイルの酸化を防止して表面品質を高めるために、熱間圧延・巻取り終了後、鋼コイルが輸送チェインのトレーに取り付けられてから、保温カバーがカバーされる。保温カバー内部に保護ガスを導入し、鋼コイル内の空気を置換する。鋼コイルの酸化を防止して鋼コイル表面品質を高める。 In the gas protection device, in order to prevent oxidation of the steel coil and improve the surface quality, the heat insulating cover is covered after the steel coil is attached to the tray of the transport chain after the hot rolling and winding are completed. A protective gas is introduced inside the heat insulating cover to replace the air inside the steel coil. Prevents oxidation of the steel coil and improves the surface quality of the steel coil.
保温カバー内部には、ガス透過孔が追加して開けられ、ガス排出バルブが取り付けられる。熱間圧延・巻取り終了後、鋼コイルが輸送チェインのトレーに取り付けられてから、保温カバー装置がカバーされ、内部空間の温度が６００℃以上にも達する。それと同時に、鋼コイルは層流冷却、帯鋼巻取りの過程において、表面に少量の湿気が付着している。設備の安全の保証及び鋼コイルの品質の向上のために、保温カバーに保護ガスを導入する前に、高温ガスを排除する。 A gas permeation hole is additionally opened inside the heat insulating cover, and a gas discharge valve is attached. After the hot rolling and winding are completed, the steel coil is attached to the tray of the transport chain, and then the heat insulating cover device is covered, and the temperature of the internal space reaches 600 ° C. or higher. At the same time, a small amount of moisture adheres to the surface of the steel coil during the process of laminar cooling and steel strip winding. To ensure the safety of the equipment and improve the quality of the steel coil, remove the hot gas before introducing the protective gas into the heat insulating cover.
保温カバー外層は高強度鉄筋板であり、保温カバーは頻繁に吊られるので、吊り強度を保証する必要がある。外部を特殊耐熱鋼材にする。中間を保温材で被覆し、中間部をアンカー釘によって固定した後、最内部に耐高温ステンレス板を敷く。後期の吊り輸送を保証するために、保温カバー頂端に吊りチャックを追加する。それと共に、鋼コイルの性質と種類により、保温カバーは他の形態（方形保温カバー、円形保温カバーの構造）に作製してもよく、温度場構造が変更すると、鋼コイルの性能向上にとってより有利である。 Since the outer layer of the heat insulating cover is a high-strength reinforcing bar plate and the heat insulating cover is frequently hung, it is necessary to guarantee the hanging strength. Use special heat-resistant steel for the outside. After covering the middle part with a heat insulating material and fixing the middle part with anchor nails, lay a high temperature resistant stainless steel plate inside. A suspension chuck will be added to the top of the thermal insulation cover to ensure late suspension transport. At the same time, depending on the nature and type of the steel coil, the heat insulating cover may be manufactured in another form (square heat insulating cover, circular heat insulating cover structure), and if the temperature field structure is changed, it is more advantageous for improving the performance of the steel coil. Is.
電気加熱装置により、保温カバーは、熱延鋼コイルの残留熱による徐冷を実現できるだけでなく、ある特殊な鋼材に対して二次加熱処理を施し、二次焼戻を実現し、鋼コイルの性能を改善し、結晶粒子を微細化することもできる。 With the electric heating device, the heat insulating cover can not only realize slow cooling by the residual heat of the hot-rolled steel coil, but also perform secondary heat treatment on a special steel material to realize secondary tempering of the steel coil. The performance can be improved and the crystal particles can be made finer.

By adding a detection element, a PLC system and a wireless transmission device to the heat insulating cover, the information in the heat insulating cover is recognized. A thermocouple for detecting a temperature change in the air inside the heat insulating cover with a temperature measuring range of 0 to 1100 degrees is inserted inside the heat insulating cover.
保温カバー内の空気や温度等のデータを地面のサーバーに送信すると共に、相関の鋼コイルデータ情報を下流へ送信するために、元の保温カバーの外面に無線リモコンボックスを取り付けることで、無線及び蓄電装置を利用して、保温カバーの移動式温度測定・サンプリング、データの無線送信、物流情報の書き込み・読み込み等の機能を実現する。 By attaching a wireless remote control box to the outer surface of the original heat insulation cover in order to transmit data such as air and temperature inside the heat insulation cover to the server on the ground and to transmit the correlated steel coil data information downstream, wireless and By using the power storage device, functions such as mobile temperature measurement / sampling of the heat insulation cover, wireless transmission of data, and writing / reading of distribution information are realized.

The heat retention, heat soaking and oxidation resistance effects of the steel are further optimized.
１．巻取り終了後、速やかに保温し、効果が一番優れている；高温領域で保温し、性能指標を有効に改善できる。低温領域で保温すると、組織変態又は冷却の不均一が既に発生しており、効果は大幅に低下する。 1. 1. Immediately after the end of winding, it keeps warm and has the best effect; it keeps warm in the high temperature region and can effectively improve the performance index. When the heat is kept in a low temperature region, tissue transformation or non-uniform cooling has already occurred, and the effect is greatly reduced.
２．有効な保温は肝心なものであり、冷却速度を変えると、材質性能に影響を与え、「層流冷却+巻取った後の冷却制御」は、高強度鋼の材質性能を改善するための重要な一環である。異なる製品は、成分の相違、温度プロセスの相違により、熱間コイルの材質特性も相違する。 2. 2. Effective heat retention is essential, and changing the cooling rate affects the material performance, and "laminar cooling + cooling control after winding" is important for improving the material performance of high-strength steel. Is a part of it. Different products have different material characteristics of the hot coil due to the difference in composition and the difference in temperature process.
３．保温時間の延長は、材質の性能均一化及び性能軟化に有利であり、９８０ＱＰ、９８０ＤＰ−ＧＩ （極限規格）、１１８０ＱＰの熱間コイル保温が≧６時間で、９８０ＣＰの熱間コイル保温が≧１２時間である場合、効果は一番優れている。 3. 3. The extension of the heat retention time is advantageous for uniform performance and softening of the material. 980QP, 980DP-GI (extreme standard), 1180QP hot coil heat retention is ≧ 6 hours, and 980CP hot coil heat retention is ≧ 12. When it comes to time, the effect is best.
