Tundish refractory coating features:
Can purify molten steel, in general, the higher the CaO content in the paint, the better the purification effect. It has good ductility, small yield value, easy construction, and can be manually applied or mechanically sprayed.
Life cycle of tundish coating:
Related to the number of coating layers, the general coating thickness is 35 ~ 40mm, the number of continuous casting furnaces is 8 ~ 10 times, and the thickness of 40 ~ 60mm is more than 10 times.
Our total annual production capacity is about 100,000 tons of dense-shaped refractory product, and 100,000 tons of monolithic refractory product.
We have three tunnel kilns for silicon-aluminum dense bricks and one new plant for the monolithic refractory.
We're sure our custom-made products and professional services will bring you a stable quality supply and more profit.
