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(简称钢的KJT工艺),是国内外钢铁企业降耗增利的主要措施之一。鞍钢每年因钢坯钢材废品损失钢材8×10~4t,价值65u0万元。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。 The implementation of slab billet temperature control and heating, reducing the defects of billet to improve the finished product rate, reduce the soaking and heating fuel consumption (referred to as the steel KJT process) is one of the major measures of reducing consumption and increasing profits of domestic and foreign steel companies. Anshan Iron and Steel scrap each year due to the loss of steel 8 × 10 ~ 4t, the value of 65u0 million. 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.
