Product Features: With the continuous development of metallurgical technology, increasingly stringent conditions tundish, tundish refractories increasingly high demand, the product has the following advantages: mobility, there is a reasonable setting time; labor saving, convenient; high strength, long life; has good insulation properties, high temperature, good thermal shock resistance, corrosion resistance, erosion. Tundish castable on overall construction and life has obvious advantages, so more and more of the iron and steel enterprises to adopt the form of the whole cast tundish life in more than 300 hours. Packing Packing: Plastic Composite ton bag, can also be packaged according to user needs to use other forms.
