喷吹技术是七十年代发展起来的一项新技术,近年来在我国炼钢工业已有应用,但在铸造生产中尚未应用。PX8201铁水喷粉设备就是为适应铁水喷粉工艺要求而研制的,目的在于大力推广稀土在铸造行业的应用,发展我国稀土球铁技术。该设备主要用于铁水的球化,脱硫和孕育变质等处理,尤以喷吹处理稀土合金更有独特优点。根据稀土元素的物理化学特性,使用传统的冲入法或压入法均不能充分发挥稀土的作用,只有喷吹法才能使稀土有效地加入到铁水中去,喷吹法是钢铁生产中稀土的有效加入方法。 喷吹法的基本原理是将所需的加入剂,制成一定粒度的粉料,利用载气使固态粉料
Spraying technology is a new technology developed in seventies. In recent years, it has been applied in China’s steelmaking industry, but it has not been applied in foundry production. PX8201 hot metal powder spraying equipment is to meet the requirements of hot metal powder technology developed, the purpose is to vigorously promote the application of rare earth in the foundry industry, the development of China’s rare earth ductile iron technology. The equipment is mainly used for hot metal ball, desulfurization and gestation metamorphism and other treatment, especially spray treatment of rare earth alloys more unique advantages. According to the physical and chemical characteristics of rare earth elements, the use of the traditional method of infiltration or press into the law can not give full play to the role of rare earth, only the injection method to make rare earth effectively added to the hot metal, injection method is rare earth steel production Effectively join the method. The basic principle of the injection method is to add the required additives, made of a certain size of powder, the use of carrier gas to make solid powder
