波兰Warszawa冶金工厂的炼钢车间,在现有的钢水真空处理设备旁安装了向钢包内钢水中进行喷粉脱硫的半生产性装置。 1980年5月在这台装置上开始进行了喷吹钙粉的试验。建造这台喷粉装置是为了减少钢内的硫含量和提高钢的纯净度。
The steelworks at the Warszawa Metallurgical Plant in Poland installed a semi-productive unit for dusting and desulphurizing the steel in ladle next to the existing ladle vacuum. In May 1980, a test of spraying calcium powder began on this installation. The dusting unit was built to reduce the sulfur content in the steel and improve the purity of the steel.
