Magnesia calcium bricks for steelmaking industry
Magnesia calcium brick is also called high calcium magnesium brick. It is a magnesia refractory with periclase as the main crystal phase and tricalcium silicate as the secondary crystal phase.
Contains MgO80%~87%, CaO6%~9%, CaO/SiO2 ratio is between 2.2~3.0. Its obvious structural characteristics are that periclase is in direct contact with dicalcium silicate and tricalcium silicate, and the eutectic (4CaO·Al2O3·Fe2O3 is filled in the crystal gap of dicalcium silicate and tricalcium silicate in thin veins). The porosity is low. The starting temperature of softening under load is generally higher than 1700 ° C, and the resistance to alkali slag is good. However, the thermal shock resistance is poor. Firing at high temperature of 1550~1600℃.
Application
It is used in the wind eye of steelmaking side blowing converter, the top of open hearth furnace and the upper part of oxygen blowing converter.
Physical and chemical analysis
Production capacity: Our factory actively response to government environmental protection policy, we designed and built the fully automatic controlled high temperature gas tunnel kiln (1700℃), and got capacity of annual output 70,000 tons of high quality refractory products.
