长钢炼钢技术全国约有330座转炉,年生产能力在1.2亿t,大于90t的转炉近60座。转炉钢产量约占全国钢产量的83％,居炼钢的主导地位。氧气转炉溅渣护炉技术得到广泛应用,转炉炉龄达到世界先进水平氧气转炉溅渣护炉技术的开发成功,使我国转炉炼钢技术起到突破性进展,炉龄的提高有力地提高了作业率,打破了过去转炉三吹二的局面(减少厂房占有地和投资),实现转炉与连铸机的合理匹配,极大地减少转炉
There are about 330 converters in the country, with an annual production capacity of 120 million tons and more than 60 converters of more than 90 tons. Converter steel output accounts for about 83% of the national steel output, ranking the leading position of steelmaking. Oxygen converter slag splash protection technology has been widely used, the converter furnace age reached the world advanced level Oxygen converter slag splash protection technology developed successfully, making China’s converter steelmaking technology breakthroughs, improved furnace age effectively improve the operation Rate, breaking the past three blowing converter two situation (to reduce plant ownership and investment), to achieve a reasonable converter and continuous casting machine, which greatly reduces the converter
