日本的连铸比巳超过90%,并在最近确立了直接轧制工艺。直接连轧工艺要求高速连铸和无缺陷板坯。shnagawa耐火材料公司为满足这些要求,研制了高速连铸用的保护渣粉料。此粉料主要用于板坯的高速连铸,并成功地用于2.o～2.5m/min的快速连铸而不发生粘结型缺陷。一般都知道高的铸速会增加 Japan has more than 90% continuous casting and recently established a direct rolling process. Direct rolling process requires high-speed continuous casting and defect-free slab. shnagawa refractory company to meet these requirements, developed a high-speed continuous casting mold powder. This powder is mainly used for high-speed continuous casting slab, and successfully used for 2. o ~ 2.5m / min rapid casting without sticking defects. It is generally known that high casting rates increase
