据德“stahl und Eisen”1992年第11期报道,钢铁产品一般要经过由冶炼铸造到变形构成的很长的生产流程。炼铁、炼钢后,经过连铸、热轧、冷轧,大多还要进行二次加工,在这个阶段半成品变成了成品。技术开发的目的是缩短生产流程,从而降低原材料、能源和设备消耗,提高生产率。采用板坯连铸是技术上的第一大进步,它完全取代了模铸,并且不 According to German “stahl und Eisen” 1992 eleventh report, steel products generally go through the smelting casting deformation to form a very long production process. Ironmaking, steelmaking, after continuous casting, hot-rolled, cold-rolled, mostly secondary processing, semi-finished products at this stage into a finished product. The purpose of technology development is to shorten the production process, thereby reducing the consumption of raw materials, energy and equipment and increasing productivity. Slab casting is the first major advancement in technology, it completely replaced the mold, and not
