一、前言目前,钢铁厂家拥有很多种固体粉料喷吹设备,可用来处理铁水和钢水。本文介绍蒂森钢铁公司的喷粉设备、冶金技术及设备结构设计的特点。目前,“钢”仍然和过去一样,是应用范围最广泛的材料。为了达到对钢的要求不断提高的各种指标,必须不断地改进钢的生产工艺和加工工艺。近几年来,由于坚持采用钢包精炼工艺,已使钢的质量有了明显的提高。通过向铁水和钢水喷吹特殊的处理剂,扩大了钢包冶金的使用范围,其前提是灵活运用喷吹方法,使之适合不同的冶金要求。提高钢的质量的一个重要前提是保证冶
I. Introduction At present, steel manufacturers have many kinds of solid powder injection equipment, which can be used to deal with hot metal and molten steel. This article describes Thyssen Iron & Steel’s dusting equipment, metallurgical technology and equipment design features. Currently, “steel” is still the same as the past, is the most widely used material. In order to meet the increasing demands on steel, it is necessary to constantly improve the steel production process and processing technology. In recent years, due to adhere to the ladle refining process, steel quality has been significantly improved. By injecting special treatment chemicals into hot metal and molten steel, the scope of use of ladle metallurgy is broadened based on the premise of flexible application of the injection method to suit different metallurgical requirements. An important prerequisite to improve the quality of steel is to ensure that the rule
