为了适应连续铸坯和炉外精炼等炼钢技术发展的需要和改善浇钢生产操作条件,近年来国内、外炼钢厂广泛采用了滑动水口浇钢技术.1. 国外滑动水口浇钢技术发展近况目前世界各国在钢铁工业中采用的滑动水口共有4000多套,年浇钢水量大约在2亿吨以上.在炼钢生产中应用滑动水口最多的国家是日本.日本炼钢厂80%以上的钢水罐都安装了滑动水口,连铸机用的钢水罐几乎全部实现了滑动水口化.目前日本钢铁厂应用的滑动水口共约有700套,其中用于模铸钢水罐的约有525套,用于连铸钢水罐的约有170套,用于转炉出钢口的有5套.
In order to meet the continuous casting slab and furnace refining and other steelmaking needs of the development and improvement of steel production operating conditions, in recent years, domestic and foreign steel mills widely used sliding gate pouring steel technology .1 foreign sliding gate pouring steel technology development Recent Developments Currently, there are over 4,000 sets of sliding gates used in the steel industry around the world, with an annual volume of molten steel of about 200 million tons, etc. The most popular sliding gate in steelmaking is Japan, with more than 80% Sliding nozzles are installed in the steel tanks, and almost all of the steel tanks used in the continuous casting machine are sliding waterways. Currently there are about 700 sets of sliding nozzles used in Japanese steel mills, of which about 525 are used for the casting of steel tanks About 170 for continuous casting of steel tanks and 5 for tapping of the converter.
