With the increasingly strict environmental protection policies now, the kiln industry has entered a peak period of environmental protection and energy conservation transformation. This year's market for high-temperature castables continues to rise, compared with last year's price per ton by a considerable increase. Today, Anrui relies on the ex-factory prices of high-temperature castables for two days as a comparison to analyze the market prices in 2020 for your reference.

We know that high-temperature castables are widely used in kilns and thermal equipment in industrial sectors such as metallurgy, petrochemicals, and power building materials. They are generally used as heat insulation layers, and can also be used as working layers or load-bearing components. Better use effect. In the parts that come into contact with liquid metal or slag, heat insulation plates are used only on the tundish. In the parts that are in contact with liquid metal or slag, only heat insulation plates are used on the tundish, and good results are obtained.

In recent years, under the situation of hot sales of new environmentally friendly energy products, high temperature resistant castables have entered the eyes of the relevant kiln industry. Under the changing market situation, high temperature resistant castables have been widely used in the long-term industry, leading the market more Many manufacturers pay attention to the production technology of castables, which reduces the production cost of refractory manufacturers to a certain extent.

With the need for energy saving in industrial kilns, high-temperature resistant castables will surely gain greater development. Its direction is light weight, high strength, low thermal conductivity, easy to use and low price. In addition, the light aggregate and the binding agent are generally used in combination, and the admixture is added to develop excellent high temperature resistant castables.

The production cycle of refractory castables is generally shorter than that of refractory bricks of the same material, so the sales volume of refractory castables is very large, so how much a ton of refractory castables becomes a very important issue, but we Nor can we simply pursue low prices, quality is the goal of the refractory industry. High temperature resistant castables have high requirements on the formulation, the particle gradation must be reasonable, and the type and amount of additives have a significant impact on the high temperature resistant castables. The construction of high temperature resistant castables and ovens must be carried out in strict accordance with the requirements, so as to ensure the service life of high temperature resistant castables

High-temperature castable is a granular and powdery material made of refractory materials with a certain amount of contact agent. With high fluidity, it is suitable for the amorphous refractories formed by casting. Compared with other unshaped refractory materials, the binding agent and moisture content are higher and the fluidity is better. Therefore, the application scale of the unshaped refractory material is wider, and the raw materials and the binding agent can be selected according to the application conditions. It can be cast directly into lining, or it can be made into prefabricated blocks by casting or shocking.

According to the different parts and purposes of each kiln, high temperature resistant castables are divided into multiple types. High-strength wear-resistant high-temperature castables include corundum high-temperature castables, steel fiber high-temperature castables; and heat-insulating lightweight heat-insulating castables and other models. The increase in market demand, the complexity of the production process and the rise in the price of raw materials determine the reason why the price of high temperature resistant castables will continue to rise in 2020.
