在试制低合金16MnXt 冷轧钢板中,由于采用了一锭一坯一卷的大卷生产,其成材率有了明显的提高。本文用统计数字,从钢坯收得率、热轧板卷收得率、冷轧成品收得率和综合成材率方面,对大、小卷生产作了比较,提出了采用大卷生产是提高成材率的有效措施。这是一切有条件的钢种都应采取的生产方式。 In the trial production of low-alloy 16MnXt cold-rolled steel, due to the use of a ingot of a roll of billet production, the finished product rate has been significantly improved. In this paper, the statistics, from the billet yield, hot-rolled coil yield, cold-rolled finished product yield and overall yield, the production of large and small volumes were compared, put forward the use of large-volume production is to increase timber Rate of effective measures. This is the mode of production to be taken for all types of steel.
