本文综述最近全国各特殊钢厂推广试验绝热帽口情况,讨论了当前普遍存在的绝热板使用后残灰刺激工人皮肤“发痛”“发痒”,和钢锭帽口线下增炭严重的二大难题。着重研究了如何制造不发痛痒的绝热板,现已初步研制成功,准备推广中。前言采用绝热帽口铸造镇静钢锭,是当前世界上模铸工艺一项重大技术革新。明显的效果是,可以比现行材质制成帽口提高成材率5—10％,现在世界各国冶金工厂都已广泛应用。但绝热板的制造工艺没有公开,仍属专利。
This article reviews the recent admissions of adiabatic hatches in various special steel mills across the country, and discusses the current “scratchy” and “itchiness” of workers’ skins after the use of commonly used insulation panels. Big problem Focus on how to create non-itching insulation board, has now been initially successfully developed, ready to promote. Preface Adopting the heat-insulated hatch to cast the killed steel ingot is a major technological innovation in the die casting process in the world at present. The obvious effect is that the material can be made of the current material than the hat to improve the yield of 5-10%, metallurgical plants in various countries in the world have been widely used. However, the manufacturing process of insulation panels is not disclosed, is still a patent.
