保护渣的制定实质上就是通过改变其化学组成及矿物组成,使之具有一定的熔点、熔速、粘度、结晶温度等特性,以满足不同钢种所需的传热、润滑、夹杂吸收、绝热等要求,从而生产出质量合格的铸坯。重点从制定熔点、熔速、粘度、结晶温度等渣性入手,讨论对铸坯表面缺陷的防治问题。
In fact, the development of mold powder is to change the chemical composition and mineral composition of the mold powder to make it have some characteristics of melting point, melting speed, viscosity and crystallization temperature to meet the requirements of heat transfer, lubrication, inclusion absorption, thermal insulation And other requirements, so as to produce qualified castings. Focus on the development of melting point, melt speed, viscosity, crystallization temperature and other slag start to discuss the prevention and treatment of slab surface defects.
