Refractory Bricks Manufacturer

Any brick that can withstand high temperatures above 1580℃ is called a refractory brick . It is a finished product obtained by mixing refractory clay with clinker (calcined and crushed clay), stirring, pressing into shape, drying and calcining. There are also siliceous and high-alumina bricks. According to the brand, it can be divided into SK32, SK34, SK36, SK38, and SK40 refractory bricks. Refractory bricks are mainly used in furnace linings, flues, chimneys, etc. According to their shape and specifications, they can be divided into two categories: standard and special-shaped. The specifications of standard refractory bricks are 230 mm × 114 mm × 65 mm, and special-shaped refractory bricks are processed on-site or required to be supplied by the manufacturer. Rongsheng Refractory Bricks Rongsheng Refractory Bricks Manufacturer Refractory bricks can be divided into two types according to their refractory degree: ordinary type (refractory degree is 1580～1770℃) and advanced refractory bri...

An induction furnace consists of a non-conductive refractory crucible surrounded by a coil of copper tubing. Running a strong alternating current through the coil creates a magnetic field that induces an electric current inside the metal and rapidly melts the charge inside the furnace through the Ohmic effect. The coil is made of hollow copper tubes through which cooling water flows. The water absorbs heat from the bath through the refractory lining and is then recirculated through a heat exchanger. A proper and well-maintained refractory lining is very important for the safe operation of an induction furnace. The physical properties of electric induction require that the neutral lining of the induction furnace be as thin as possible. At the same time, it must be thick enough to adequately protect the coil from metal depletion due to corrosion and mechanical shock. Ensuring that the lining remains within the limits specified by the manufacturer requires careful use of the lining as wel...

"Abrasion resistance" is also called wear resistance, the wear resistance of materials, expressed by the amount of wear or the wear resistance index. Wear is a very common phenomenon, and there are many reasons for this phenomenon, including physical, chemical and mechanical factors. The main ones are: abrasive wear, adhesive wear (bonding), fatigue wear (pitting), and corrosive wear. In terms of adhesive wear, when solid surfaces come into contact, their high and low peaks will prevent the two solid surfaces from 100% contact. The protruding parts come into contact with each other, and due to the large pressure, they produce plastic deformation, which causes cold welding, that is, adhesion. The adhesion part causes one side of the weaker material to be sheared due to friction and sliding, causing the material to be adhered from the weaker side to the stronger side. Main factors affecting material wear resistance Hardness The wear resistance of metal materials can be measured...

A cement rotary kiln is an important thermal equipment for producing cement clinker. In traditional cement rotary kiln maintenance operations, refractory castables are mostly used for repair. Although the construction of refractory castables is much simpler than refractory bricks, it still cannot meet the requirements of quick repair of cement kilns. Therefore, companies have gradually accepted the use of refractory plastics that do not require formwork or baking for quick repairs. Rongsheng Refractory Plastic Manufacturer can provide high-quality refractory lining materials for cement rotary kilns, including various anti-stripping bricks, anti-erosion bricks, insulation bricks, refractory and wear-resistant castables, wear-resistant plastics, etc. Contact Rongsheng for free samples and quotes. Performance comparison between spray plastic and traditional plastic Traditional refractory plastic is mostly applied by hand and ramming. Although it is much better than refractory castable ...

The main core equipment for the incineration of organic waste liquid is the incinerator. Different furnace types need to be selected according to the nature and treatment requirements of the waste liquid. At present, the incineration treatment of organic waste liquid is becoming more and more popular, and the refractory materials of the incinerator are the key restrictive factors of this method. Rongsheng Refractory Materials Manufacturer pointed out that no matter what material the lining refractory materials are made of, they will be subjected to long-term high temperature, high pressure, temperature changes, atmosphere changes, and slag erosion on the lining during the industrial production process. The damage forms of refractory materials are usually erosion, scouring, cracking, etc., among which erosion belongs to continuous damage, while cracking and spalling belong to discontinuous damage. The eroded refractory materials will form cracks and crack the refractory materials due t...

The application of refractory bricks in iron and steel mills can be said to be an indispensable part of the steel industry. During the iron and steel-making process, the temperature in the furnace is extremely high, and a material that can withstand this high-temperature environment and remain stable is needed as the furnace lining. Refractory bricks are the ideal choice to meet this demand.
