LMM product segment
Please provide design data for special processing requirements
Tundish pre-casting parts include slag wall, slag weir, impact plate and current regulator etc. It applies magnesium sand, alumina, white corundum as main ingridients. Materials combines micro powder and ultra-micro powder, adding with certain amount of coagulant and dispersant, forming by pre-casting, and baking at medium temperature.It is applicable to continuous tundish. The pre- casting parts can meet with different requirements on lifespan and design requirement.
1.Improving the Flow of Steel
The dead zone in the bottom area of tundishcan be effectively eliminated. It can help to improve the flow trajectory of molten steel , absorbe the slag and limit the eddy current caused by casting impact. It can achieve the role of slag blocking and purifying molten steel.
2.Cut Production Costs
Higher service life prolongs the life of the tundish, indirectly optimizes the turnover, and reduces the cost of production effectively.
