READ MOREAfter CHNZBTECH undertook the 60tVD vacuum refining furnace upgrade project, it has arranged equipment engineers and process engineers to visit the site many times, through equipment testing and diagnosis, optimizing the design, replacing nozzles, adding steam-water separators, steam pipes, adding
READ MOREThe existing furnace covers of steel-making electric furnaces mostly adopt the structure of masonry refractory bricks. The disadvantages of the furnace covers of this structure are many brick cracks, poor overall performance, high energy consumption, short service life, and long maintenance.
READ MOREChina produces about 200 million tons of iron and steel waste (such as trimming, trimming, scrapped machinery, household waste, etc.) every year. The LF ladle refining furnace is a kind of molten steel refining treatment device built after the primary furnace (converter, electric furnace). The LF pr
