一、前言自60年代初我国采用混合的固体氧化物(以下简称保护渣)保护钢水浇铸以来,粘模问题一直未得到解决。尤其是近年来,考虑到使用高含量石墨保护渣造成钢锭头部和锭身表面增碳的后果,许多钢厂为了提高钢材质量,希望降低保护渣中碳含量。但是在研制低碳渣的过程中,首先遇到的被认为难以克服的技术关键问题,就是粘模问题。使用后的保护渣液渣层不规则地牢固地粘结在钢锭模表面,在钢锭模再次使用前必须清除干净。若清理不净,粘在模壁上的渣 I. INTRODUCTION Since the early 60s, China has adopted a mixed solid oxide (hereinafter referred to as mold flux) to protect the molten steel casting, the sticky mold problem has not been solved. In recent years, in particular, many mills want to reduce the carbon content in mold fluxes in order to improve the quality of steel, in view of the consequences of using high levels of graphite mold flux to cause carbon addition on the surface of the ingot head and ingot. However, in the process of developing low-carbon slag, the first key technical problem that is considered to be hard to overcome is the sticking mold problem. After use, the flux slag layer irregularly and firmly adheres to the surface of the ingot mold, and the ingot mold must be cleaned before being used again. If not clean, stuck in the mold wall slag
