經濟部中央標準局員工消費合作社印製 B7 五、發明説明(/ ) 本發明關於一種用於生產熱滾壓平坦產物的生產設備 ’由一多滾子架式滾壓道,一個具有冷却熱鋼帶用的冷却 裝置及後設之捲取機(M捲取鋼帶)的出口滾子道所構成 〇 今日用於生產熱滾壓钃帶的滾壓設備一般之設置及操 作方式,係使個別滾子架中的變形呈沃斯田鐵方式達成, 換言之,係確使個別滾子架中的滾壓溫度在锇碳相圈的G 〇S線上方。在最後一道滾壓批次(它必須儘量接近GO S線以達成一種细顆粒之終姐織)冷却到鉸盤溫度,且在 冷却的部段或捲取的鋼帶段中組锄有轉變。 對於碳含量少於0 .2%的鋼而言,依上述方法的滾 壓作業,終滾壓溫度(亦即在滾壓道的最後的滾子架中的 溫度)為840〜920Ό,依碳含量多寡而定。终滾壓 溫度之保持,係藉選擇終端滾壓速度而達成,藉此可利用 滾子架的驅動功率而控制滾壓道中餌帶的自然冷却以及熱 量的供懕。對於鋼帶最小厚度(依滾壓道類型而定,在度 量级1 .3mm)以上的鋼帶厚度,這種方法可毫無問題 地應用。如果少於此鋼帶厚度,則所需之·滾壓速度在1 2 米/秒Μ上,這是在滾壓道後方在滾子道上自由出口處所 不再能控制者。 雖然有這種問題,但發展的趨勢仍朝向較小之终端厚 度,因此須找出途徑將终滾壓溫度降低,俾能使滾壓速度 較小。這種滾壓程序稱為肥粒撖式滾壓,因溫度係在G 0 本纸張尺度適用中國國家標準(CNS ) Α4規格(210 X 297公釐) --------·¥------1Τ------線- (請先閲讀背面之注意事項再填寫本頁) 經濟部中央標準局員工消費合作社印装 3HSd〇 A7 B7 五、發明説明(>) S線K下的溫度(亦即在α、7混晶區域中)或在GPS 線下方在肥粒鐵範圍中達成。 一種較佳的方法係在沃斯田鐵範圍中預滾懕到一中間 厚度2〜8mm,而一完工滾壓係在肥粒鐵範圍中滾壓到 最小終厚度,在1 .3mm以下。在此二程序階段之間, 滾壓物須從沃斯田鐵範圍的终滾壓溫度冷却到肥粒鐵範圍 的滾壓溫度。這表示在第二變形階段溫度從84 0〜9 2 0Ό的範圍到6 0 0〜7 8 0C的範圍Μ後的終滾壓溫度 同樣在600〜780C範圍,也就是在此量级時,在捲 取到鉸盤上後,在捲取的鋼帶段中會發生組绷之再结晶作 用,產生的組織可使產品能直接應用*而不需做進一步冷 轉變或熱處理。 一種好结果的前提係對於從沃斯田鐵範圍進入肥粒鐵 範圍的冷却作業保持一最少之冷却時間。為了要使沃斯田 鐵能充分地轉變成肥粒锇,故必須保持這種最少的冷却時 間。這種時間各依進入第一肥粒鐵式轉變所選定之溫度而 定,在1 0〜2 0 0秒間。 要實拖上述的程序,在傳統設計的熱·延壓鋼帶滾壓道 有相當的困難。從沃斯田鐵轉變到肥粒鐵的過渡階段須在 2〜8mm的厚度範圍進行,換言之,在這種厚度範圍時 ’滚壓物大約位於傳统完工滾壓道中央。由於在此位置從 一滾子架到下一滾子架的通過時間只有幾秒,要作冷却, 原理上雖可行,但要保持轉變作用所霱的時間則毫無辦法 -4- 本紙浪尺度適用中國國家標準(CNS > A4说格(210X297公釐) --------i-----—.IT-----.^- (請先閲讀背面之注意事項再填寫本頁) 經濟部中央標隼局員工消費合作社印製 A7 B7 五、發明説明(3 ) 。因此依上述方法做肥粒戡式滾壓,對傳統設計的熱延壓 鋼帶滾壓道而言係不可能者。 針對此背景技術,本發明的目的在於提供一種熱鋼帶 之肥粒鐵式滾壓壓用的生產設備,藉之解決上述之缺點及 問題。本發明的目的亦闞於一種方法,藉之使熱鋼帶能在 肥粒鐵範圍中毫無問題地作完工滾壓。 茲配合圖式說明本發明。第一圖係本發明裝置的示意 圖° 在上述種類的生產設備中,依本發明,這種問題達成 之道·係將一種單-至多滾子架式的緊密滾壓道(6)附 加地設置在傳统設計的熱延壓網帶滾壓埴(3)的鉸盤設 備(5)後方(見第一圖)。這種滾壓道特別為在肥粒鐵 範圍中的轉變而設計。為此,工作滾子的直徑小於500 mm,且設有調整及調節回路,以使鋼帶的厚度及平坦度 可Μ達到冷鍛產品所需的差裕度(容許誤差)(Tolerance )0 在滾壓程序整個過程中,傅統設計的熱延壓鋼帶滾壓 帶(3)用於藉在沃斯田鐵範園中滾壓K造成中間厚度, 而緊密之肥粒鐵式轉變階段(6)則負責在肥粒鐵範圍中 作終滾壓。從沃斯田鐵範圍出來而具中間厚度的鋼帶要冷 却肥粒鐵範圍的冷却作業,係用最簡單的方式,通過沃斯 田撖變形階段(3)及肥粒鐵變形階段(6)之間的出口 滾子道而達成。此安全通過時間(此足夠之時間確保在正 本纸張尺度適用中國國家標準(CNS > A4規格(210X 297公釐) --------—裝----I-^ 11-I n ^ (請先閱讀背面之注意事項再填寫本頁) 經濟部中央揉準局員工消费合作社印製 A7 B7 五、發明説明(7 ) 常情形中之肥粒鐵式滾壓時能有所需之冷却以及從沃斯田 鐵轉變成肥粒鐵)係取決於此滾子道之長度(該滾子道須 為K沃斯田鐵式滾壓過的鋼帶冷却到铰盤溫度而設計)而 決定。對於沃斯田鐵式滾壓移序所用之冷却裝置(9)在 有必要時*可加入K達成所需之冷却速率。如果從最後一 道沃斯田锇式變形(3.1)直到第一道肥粒鐵式變形( 6 .1 )的通過時間不足使沃斯田鐵充分轉變成肥粒鐵, 則設K一個被加熱的捲繞段儲存器(圖中未示),它要直 接設在傳统鉸盤設備(5)與緊密之肥粒撖式變形階段( 6 )之間。 緊跟在緊密肥粒鐵式變形階段(6)後方,設有特別 為捲取薄鏑帶(7)用而設計的鉸盤(8)。由於此處不 再考慮較厚钃帶的情形*故這類裝置的構造可毫無問題。 在第一圖中所示的沃斯田锇式及肥粒鐵式滾壓用的熱 網帶生產設備(1)前方在第一個多滾子架式滾壓道(3 )前方設有一前滾壓道(12)(不作詳示)或一具鑲造 櫬(1 3 )的薄鋼板爐。 用本發明的構想一整個設備可用最佳方式做沃斯田鐵 式程序及肥粒鐵式程序。 本紙張尺度適用中國國家標窣(CNS ) A4規格(210X297公釐) ---------I------1T-----^ (請先閲讀背面之注意事項再填寫本育)
