Refractory materials are the main components of glass melting furnaces, which have a decisive influence on glass quality, energy consumption, and product costs. The future of glass melting technology depends to a certain extent on the progress of refractory materials’ manufacturing technology and the improvement of product quality. Therefore, understanding the common cracks on the … Read more
The high alumina castable manufacturing is mainly based on the synthesis of high aluminum aggregate, powder, and additives. It has high-temperature performance, high resistance, high temperature, shrinkage, wear resistance, and other characteristics. It is widely used in hardware, smelting, chemical industry, non-ferrous metal, and other industries, especially in the iron and steel industry. High alumian … Read more
It is well known that it is very important to choose the right refractories according to the different temperatures in kilns. Generally speaking, the refractory temperature range of corundum brick is 1600~1670℃. The alumina content of corundum refractory bricks is more than 90%, and the maximum temperature in use can reach 1650℃, the service temperature … Read more

Acid refractory is refractory with silica content greater than 93%. Resistant to acid slag at high temperatures. There are mainly quartz glass products, fused quartz recombination products, silicon brick and silicon amorphous refractory, is a strong acid. The semi-siliceous refractory is medium acidic. Clay refractory is called semi-acidic or weakly acidic refractory. Zircon and sic … Read more
As is known to all, a hot blast furnace is a thermal equipment that heats the air pumped into the blast furnace from normal temperature to high temperature. Equipment types are mainly divided into internal combustion type and external combustion type. The furnace is mainly composed of a regenerator and a combustion chamber. Professional refractory … Read more

The production process of magnesia carbon bricks is mainly made of electrofused magnesia and flake graphite as main raw materials, phenolic resin as binder, and some antioxidants added through the processes of heat maturation mixing, high pressure molding and heat treatment. Magnesia carbon brick sales even by ultra-high arc burning, the loss of quality is … Read more
Refractories are generally divided into two types, namely, unshaped refractory and shaped refractory. Unshaped refractory also known as castable, is by a variety of aggregate or aggregate and a or a variety of adhesive and agent composition of the mixture of powder particles, use must be mixed with a or a variety of liquid stir … Read more
Magnesia brick is a kind of alkaline refractory material with magnesium oxide content above 90% and magnesite as main crystalline phase. It can be divided into sintered magnesia brick and chemically bonded magnesia brick. The magnesite brick with high purity and high firing temperature is called directly bonded magnesite brick due to its direct contact … Read more
