Reasonable configuration of refractory materials for various specifications of blast furnaces, including main trenches, branch trenches, slag trenches, and swing flow channels, can achieve rapid production of refractory materials for iron tapping yards Baking can meet the requirements of fast production pace in iron factories, with high strength, erosion resistance, and long service life.
Overall contracting of refractory materials for the iron yard
Refractory materials for ironmaking
Detailed Introduction
Reasonable configuration is made for the different technical requirements of the main trench, branch trench, slag trench, and swing flow channel of various specifications of blast furnaces, and the refractory materials used in the production of iron tapping yards can achieve rapid production Baking can meet the requirements of fast production pace in iron factories, with high strength, erosion resistance, and long service life.
Capable of overall contracting, with a one-time railway capacity of over 170000 tons.
