中大型钢锭电渣冶金制备技术研究进展

Research Progress in Electroslag Metallurgical Preparation Technology for Middle and Large Steel Ingots

由于电渣重熔法具有金属纯净、组织致密、铸锭表面光洁等特点,针对条件要求苛刻的中大型钢锭已广泛采用电渣重熔及其衍生技术进行生产。对电渣重熔技术、液态电渣技术、双回路电渣重熔技术、电渣熔焊技术4项中大型钢锭生产技术的原理及研究进展进行介绍和评价。随着电渣复合概念的普及,提出采用电渣铸焊技术生产中大型钢锭,并对其技术优势进行阐述。

Electroslag remelting method has the characteristics of pure metal, dense structure, and smooth surface, which is widely used to produce large steel ingots with demanding conditions combined with its derivative technologies. The principles and research progress of four kinds of large-scale steel ingot production technologies were reviewed, including electroslag remelting technology, liquid-metal electroslag technology, double-circuit electroslag remelting, and electroslag remelting-welding technology. With the popularization of the electroslag composite concept, the electroslag welding technology was proposed to produce large-scale steel ingots, and technical advantages were expounded.
