B10钢锭模1966年投产以来,受生产条件影响,原砖衬保温帽经过几次修改,帽容比由原设计的15％增到16.5％,钢坯成坯率处于较低水平。冶金工作者历来把提高钢材收得率列为经常的奋斗目标之一,我们进行的不同衬砖材质的保温帽帽部钢液热平衡测定结果证实,轻质砖衬保温帽在降低帽容比方面有着明显的潜力。然而试验表明该砖衬寿命过短,难以正式应用于生产上。这样就揭示了推广应用绝热板保温帽的必要
Since the B10 steel ingot mold was put into operation in 1966, due to the influence of production conditions, the original brick lining insulation cap has been modified several times, the cap capacity has been increased from 15% of the original design to 16.5%, and the billet billet forming rate has been kept at a relatively low level. Metallurgical workers have always been to improve the yield of steel as one of the regular goal, we carried out the lining of different materials, thermal insulation cap cap liquid steel thermal equilibrium measurement results confirmed that lightweight brick lining thermal caps in reducing the cap ratio Has obvious potential. However, tests show that brick lining life is too short, it is difficult to formally applied to the production. This reveals the need to promote the use of insulation panels insulation cap
