High alumina refractory bricks play an extremely important role in industrial furnaces due to their excellent high temperature resistance. According to different classification standards, high alumina refractory bricks can be subdivided into multiple types to meet various specific application requirements. The following are the main classification methods of high alumina refractory bricks: Classification according to …
The main raw materials for magnesium-carbon bricks include: sintered magnesium sand or electrofused magnesium sand, scaled graphite, and organic binding agent. The main raw material used in the production of magnesium carbon brick is magnesium sand. In the choice of magnesium sand to ensure the quality of magnesium carbon bricks, should be used in low …

Refractory raw materials No matter how the technology develops, refractory raw materials are the basis of refractory materials. Refractory raw materials directly determine the quality of refractory materials and affect the development of refractory materials. All the development of new refractory materials cannot be separated from the support of refractory raw materials. For example, magnesia-alumina …
Refractory castables are a type of unshaped refractory materials. They are a mixture of refractory aggregates, binders and admixtures, which can be used as mud after adding water (or liquid binder) and mixing. Refractory castables have a certain coagulation and hardening time after construction. Therefore, after casting and forming, they need to be cured for …

The ladle slag line is the part where the molten steel is in direct contact with the air. At present, most of the ladle slag line masonry uses magnesia carbon bricks. Due to the temperature difference and the existence of oxygen-rich environment, the erosion rate of this part is significantly faster than other parts. In …

1.Furnace bottom There are three structural forms: full ceramic, full carbon brick and integrated furnace bottom. In the past, when designing the furnace bottom, heat dissipation and cooling conditions were not taken seriously, which was a typical corrosion-inhibiting full ceramic design. At present, this form is only suitable for the furnace bottom structure of small …
