实行钢锭钢坯控温均热与加热,减少坯材缺陷提高成材率,降低均热与加热燃耗(简称为钢的KJT工艺),是国内外钢铁企业降耗增利的主要措施之一,并为之开展了大量研究与试验工作。鞍钢因钢坯钢材废品每年就损失钢材8万吨,价值6500万元。大量缺陷坯落地精整,影响热装温度,增加能耗和工时,降低生产能力,有的缺陷还直接影响人身与设备安全。80年代以来,对缺陷的相当
The implementation of ingot billet temperature control and heating, reduce the defects of billets to improve the finished product rate, reduce the soaking and heating burn (referred to as the steel KJT process), domestic and foreign steel companies is one of the main measures to reduce consumption and increase profits To carry out a large number of research and experimental work. Anshan Iron and Steel slab scrap steel annual loss of 80,000 tons worth 65 million yuan. A large number of defects blank finishing, affecting the hot loading temperature, increase energy consumption and working hours, reduce production capacity, and some defects also directly affect the safety of personal and equipment. Since the 1980s, the flaws have been quite
