Refractory Ladle well block is composed of tabular corundum particles, tabular corundum fine powder and chromic oxide fine powder, and calcium aluminate cement is the binder. At high temperatures, chromium oxide and alumina can form a high temperature solid solution, while forming a partial solid solution of MgO-Cr2O3-MgO-Al2O3 with a small amount of magnesium oxide.
Refractory Ladle well block has the characteristics of stable structure, large air permeability, high blowing rate, erosion resistance and long service life. It is conducive to the purification of liquid steel, uniform composition and temperature, suitable for long-term treatment of molten steel or special treatment of refining furnaces. Suitable for ladle refining. Several series of products can meet the requirements of different casting conditions.
Refractory Ladle well block is a refractory ladle well block which is attached to the bottom of a steel drum and holds the water outlet bricks. Its shape is square, so it is also called square brick. The role of the brick is to fix the position of the water nozzle; Easy to disassemble and install water nozzle; Support the lower end of the stopper when pouring; When pouring is finished, ensure that the stopper slides along the arc to the water nozzle to cut off the injection flow. The brick material can be clay, high aluminum or no high aluminum.
Product features:
1, Fe2O3 or slag has a strong corrosion resistance, can effectively prevent steel slag penetration and erosion at high temperature.
2, with thermal shock resistance, corrosion resistance, improve the oxidation resistance of iron oxide slag.
3, high strength, erosion resistance, corrosion resistance, not easy to penetrate steel, high blow penetration rate, long service life.
