前言热轧厂1700热连轧机的全套设备,是由日本引进的,1978年12月投产,年产薄板300万吨。合同规定,日方仅对8个日本钢种提供技术指导。考虑到今后不可能依靠进口日本板坯生产,必须尽快使用武钢自产板坯(包括含铜钢)轧出合格的钢卷。在日方不提供技术指导和质量保证的情况下,能否用武钢自产坯生产出合格的钢卷,关键在日方提供的数学模型能否适用于武钢自产钢的生产。如果不能,就必须尽快研制出适用于自产钢坯的数学模型。这就是为什么要研究武钢自产钢热连轧数学模型的出发点和归宿。
Preface Hot-rolling mill 1700 hot rolling mill full set of equipment, is introduced by Japan, put into operation in December 1978, with an annual output of 3 million tons of sheet metal. The contract stipulates that Japan will provide technical guidance to only eight Japanese steel grades. Considering that in the future it is impossible to rely on imported Japanese slab production, it is necessary to use WISCO’s self-produced slab (including copper-bearing steel) to roll out the qualified coil as soon as possible. In the absence of technical guidance and quality assurance from Japan, whether WISCO can produce qualified steel coils with its own billet is the key to whether the mathematical model provided by Japan can be applied to the production of WISCO’s own steel products. If not, a mathematic model for self-produced billets must be developed as soon as possible. This is why it is necessary to study the starting point and destination of the mathematical model of hot strip mill produced by Wuhan Iron and Steel.
