一、前言 钢包吹氩是大家比较熟悉的冶金新技术之一。它起源于法国,早在1959年法国钢铁研究院便在5吨钢包中进行试验。1963年SAFE厂转入工业性生产,称为“Gazal”法,吹氩技术不久便在各国冶金行业中受到重视,得到研究和推广应用。我国也有不少单位采用这一新技术以提高钢的质量的。钢包容量由5吨发展到150吨,生产规模越来越大,在吹氩方法上,各厂也依据其产品的技术要求具有各自的工艺特点,有用滑动水口
I. Introduction Ladle argon is familiar to everyone one of the new metallurgical technology. It originated in France, as early as 1959, the French Iron and Steel Institute in 5 tons of ladle to test. SAFE factory in 1963 into industrial production, known as the “Gazal” law, argon blowing technology soon in the metallurgical industry in all countries attention, be research and promotion. Many units in our country adopt this new technology to improve the quality of steel. Ladle capacity from 5 tons to 150 tons, the scale of production is getting bigger and bigger, in argon blowing method, the plants also have their own technical characteristics according to the technical requirements of their products, a useful sliding gate
