1 改造前概况及问题西钢一轧厂有两条生产线:中型线开坯,以9英寸钢锭为原料,经φ550×2轧机(一列),生产60~2-95~2坯料,供小型线及二、三轧钢厂。小型线轧材,以60~2-80~2为原料,经φ500×1/φ250×5轧机(二列),生产φ16-φ28mm圆钢和螺纹钢。企业于九六年七月实现全连铸后,一轧厂充分利用二条生产线、在同一座厂房内的条件,在投入极少的情况下,用“s”型弯辊道进行热连接,实现了中、小型横列轧机一火成材。工艺流程为:120~2连铸坯→中型
1 before the transformation of the general situation and problems A rolling mill in the West has two production lines: medium-line open billet, 9-inch ingot as raw material, φ550 × 2 mill (a row), the production of 60 2-95 ~ 2 blank for small lines And second and third rolling mill. Small-sized wire rod mill, 60 ~ 2-80 ~ 2 as raw material, φ500 × 1 / φ250 × 5 mill (two columns), the production of φ16-φ28mm round bar and rebar. After the company realized full continuous casting in July 1996, a rolling mill made full use of the two production lines and the conditions in the same factory were connected by “s” -type bending rollerways with minimal investment , To achieve a medium and small horizontal mill a fire into a timber. Process: 120 ~ 2 continuous casting billet → medium
