Description

1257883 (1) 九、發明說明 【發明所屬之技術領域】 本發明係關於受熱的金屬坏料連續熱軋，受熱的坏料 在被處理的過程中被縱切成完工的成品，如棒或桿。 【先前技術】 在一傳統的連續熱軋機中，一示範性的輥軋圖被示於 鲁第1圖中，一典型的坏料10—開始被加熱至約1050—^50^ 的溫度。該坏料然後在一連串沿著一路徑線p〗被安排的輥 軋台1 V-12H/V中被輥軋成爲第一處理部分12。如第2A圖 所不，該第一處理區12具有橫向設置之截面積相等的片段 1 4，它們係以中間的第一網狀物！ 6相連結。 在剌參照第1圖，第一網狀物1 6在1 8處被縱切用以將 片段14分隔開來，該等片段然後被引至分開的路徑線P2， 用以在輥軋台13H-16 H/V被繼續輥軋成爲第二處理部分20 φ 。如第2B圖所示，每一個第二處理部分20亦都具有橫向設 置之截面積相等的片段2 2，它們係以中間的第二網狀物2 4 相連結。 在第1圖中的26處，第二網狀物24被縱切用以將片段 22分隔開來，該等片段然後被引至分開的路徑線P3a-P3d， 用以在完工區塊”Μ”的輥軋台17-24中的某些或所有輥軋台 上被輥軋成爲完工的成品28。 因爲處理部分12及20被縱切成爲具有相同截面積的片 段，所以完工區塊都被送入相同的縱切片段22。這大大地 -4- (2) •1^57883 限制了在一給定的輥軋路徑設計及導引設定下可被該輥軋 機所製造的產品的範圍。舉例而言，假設進入的坏料的尺 寸爲160x160mm且截面積爲26,322mm2，其中縱切片段14 及22分別具有32.4mm2及15.6mm2的截面積。 參照第3圖並使用設置在路徑線P3a上的完工區塊，即 可獲得下列的輥軋順序及成品： 輥軋順序 完工尺寸（直: 17-24 6.3mm 17-22 8 mm 17-20 10mm 17-18 12.5mm 爲了要製造其它的產品’該輥軋機必需停機來將輥軋 路徑重新設定及更換導引件。 本發明的一主要目的爲擴大在使用縱切的輥軋機中的 一給定的輥軋路徑安排下所能夠同時輥軋的產品的範圍。 本發明的另一個目的爲在達到上述擴大產品範圍的同 時亦能夠提高該輥軋機的每小時生產量。 【發明內容】 依據本發明，一種經過加熱的坏料，其一開始被輥乳 成爲一具有被橫向設置之至少第一及第二片段的處理部分 ，該至少第一及第二片段是由一中間網狀物連結起來，其
-5- (3) 乜57883 中該第二斷片的截面比第一片段的截面大。該中間的網狀 物被縱切以分隔該第一片段及第二片段。該第一片段接著 被輥軋成爲第一尺寸範圍的產品，同時該第片段被輥軋成 爲較大的第二尺寸範圍的產品。 【實施方式】 依據如第4圖所示的本發明，一如前文所述之經過加 φ 熱的坏料10在一連串沿著路徑線Pi安排的輥軋台IV-12H/V 處被輥軋成爲第一處理部分30。然而，如第5A圖所示的 ，與前文所述之具有相同的截面積的片段的處理部分12不 同地，處理部分30具有不同截面積之第一及第二片段，它 們透過一中間網狀物3 6連結在一起。 在第4圖的3 8處，該網狀物3 6被縱切用以將片段3 2， 3 4分隔開來。較小的片段32被導引至路徑線P2且被輥軋台 13H-16H/V輥軋成爲一第二處理部分40。如第5B圖所示的 φ ，該第二處理部分40是傳統的形狀，其具有截面積相同的 第三片段42，它們係透過一第二中間網狀物44連結在一起 。在46處，網狀物44被縱切用以將第三片段42分隔開來。 第三片段42然後被導引至第1圖所示的路徑線P3a & P3b，用 以輥軋成完工的成品2 8。 雖然第三片段42在路徑線P3 a及P3b上的輥軋台處被輥 軋成爲完工的成品28，但較大的切片段34則是被導引至另 一路徑線P4，用以將其輥乳成爲一較大的完工成品4 8。 假設該進入的坏料1 0與第1圖中的胚料相同，即該第 -6- (4) Ί257883 一及第二縱切片段32及34分別具有30 mm2及4 0 mm2的截積 ’第三縱切片段42具有15.6mm2的截面積。在此等尺寸下 ’由路徑線及P3b所產生出來的完工成品28將具有前文 所述的直徑爲6.3 mm，8.0 mm或12.5mm的圓形物。然而， 如第6圖所示的，在路徑線P4上的輥軋台輥軋的較大的縱 切片段3 4在下列的輥軋順序下可獲得下列的完工成品：
輥軋順序 完工尺寸（直徑） 13-22 12.0mm 13-20 16.0mm 13-18 2 0.0mm 13-16 2 5.0mm 13-14 3 2.0mm 13-22 14.0mm 13-20 1 8.0mm 13-18 2 2.0mm 13-16 2 8.0mm 藉由一開始將該經過加熱的坏料1 0輥軋及縱切以產生 不相同的截面積之分離的片段32，34，這些片段就可被進 一步製造成不同尺寸範圍的完工成品。此一被加強的製造 彈性可在無需將該輥軋機停機進行輥軋路徑的重新安排& 更換導引件下來達成。 處理部分30之較大的片段34亦可讓提高該坏料的速度 -7- (5) 1257883 成爲可能，而這可提高該輥軋機每小時之以噸計的產率。 有鑑於以上所述，應被瞭解的是，以上所述處理部分 及輥軋圖只是可應用本發明的諸多例子中的示範例而已， 本發明的基本槪念爲將處理部分縱切成至少兩個截面積不 相同的片段，接著將這些片段同時輥軋成爲不同尺寸範圍 之完工成品。 % 【圖式簡單說明】 本發明現將參照附圖作較詳細的說明，其中： 第1圖爲使用傳統縱切技術的輥軋機的輥軋圖； 第2A及2B圖爲1圖的輥軋機所製造的處理部分的剖面 圖； 第3圖爲第1圖中之諸完工區塊中的一個完工區塊的輥 軋圖； 第4圖爲使用本發明的縱切技術的輥軋機的輥軋圖·， # 第5 A及5 B圖爲4圖的輥軋機所製造的處理部分的剖面 圖；及 第6圖爲第4圖中之諸路徑線中的一條路徑線的輥軋圖 【主要元件符號說明】 1〇 坏料 1 2 第一處理部分 Μ 片段
