一、概况 我厂在一九七四年开始生产油桶板,当吋由空气侧吹转炉冶炼,浇注成12时钢锭,经650轧机轧成板坯(11.3×260×680毫米)然后由薄板车间经过如下工艺流程: 板坯加热→轧制→成品剪切→揿板→初
I. Overview Our factory started to manufacture oil drum plate in 1974. When it was smelted by blowing air from the air side and poured into a 12-hour ingot, it was rolled into a slab (11.3 × 260 × 680 mm) Workshop through the following process: slab heating → rolling → product shear → 揿 plate → early
