Unshaped refractory material is an important refractory material, which is widely used in various high-temperature industrial furnaces, kilns, thermal equipment, etc. due to its excellent refractory and structural properties. There are various types of amorphous refractory materials, and their classification methods are also diverse. Among them, classification based on the type of binder, refractory aggregate, and construction method has great practicality and is widely used in the industry.

See detailsCarbon bricks are mainly used to build the furnace walls, bottom, and below the blast furnace tuyere of the non exposed air part of the submerged arc furnace, as well as the furnace hearth and tapping channel. Due to the high conductivity of carbon bricks, when using carbon brick furnace lining, the electrodes are easy to lift up, and the height of furnace wall carbon bricks and the thickness of furnace bottom carbon bricks can be appropriately reduced.
See detailsThe anti-seepage casting material has the characteristics of low thermal conductivity and strong resistance to penetration, which can prevent the infiltration and erosion of aluminum liquid and liquid, thereby extending the service life of the electrolytic cell. At the same time, the anti-seepage casting material increases its thermal conductivity due to the electrolyte entering the refractory insulation layer, resulting in an increase in the power consumption of the electrolytic cell. Moreover, the construction of anti-seepage materials is fast and convenient, and they can quickly heat up without the need for baking. They are mainly used in electrolytic cells to replace refractory bricks and Al2O3 layers as impermeable layers. They are a commonly used refractory material for aluminum melting furnaces.
See detailsThe parts that usually come into direct contact with flames are the inner wall and bottom of the furnace. These two parts are exposed to high temperatures and chemical erosion for a long time, and are subjected to erosion and corrosion from combustion materials, exhaust gas, and chemical reaction products, so these two parts are more prone to damage
