Neutral Ramming Mass Material for Induction Furnace

-
图片
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...

How to Evaluate the Wear Resistance of Materials?

-
"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...
