Where is the best refractory material? 5

Chinalco Jinlu Refractory is the largest refractory manufacturer in Shanxi Province, and the company cooperates with Central South University to carry out industry-university-research base. It consists of the first factory (stereotyped products), the red mud fly ash lightweight insulating brick factory, the second factory (unshaped refractories), the furnace construction branch, the special nai branch, the corundum branch, the special pottery branch, the silicon carbide branch, the steel ball factory, the freight station, etc. Among them, the technical center in the factory has obtained the provincial refractory inspection qualification.

The company produces silica bricks, high-alumina bricks, clay bricks, phosphate bricks, lightweight heat-insulating bricks, corundum mullite, magnesia-chrome bricks, alkali-resistant bricks, high-strength wear-resistant bricks, silicon carbide combined with silicon nitride bricks and dozens of various refractory products for various kilns and various amorphous refractories.

Industry insiders know that the Xinmi area has always been a famous production area for shaped refractories, Zhengzhou Stirrup Furnace **** is very famous in Xinmi, the quality is good, the sales are good, you can go to his company to see.

Henan's refractory materials are better: Gongyi (refractory bricks), Dengfeng (refractory cement), Yuzhou (unshaped refractory castables).

There are many varieties, **reasonable, ***.

Haicheng Houying Group, Dashiqiao Blue and White Group.

These things are most abundant in the Luoyang area of Zhengzhou, Henan, especially the Mixian area of Zhengzhou. There are too many refractory plants to count. The larger ones include Jinghua, Warwick, Zhenjin, Oriental, etc., with annual sales of hundreds of millions.

According to the composition of chemical minerals, refractories include siliceous, aluminum silicate, corundum and other materials. Our common refractories include magnesia, magnesia, calcium, carbon composite refractories, zirconium and special materials.

Classification of refractory materials: method of classification: Woo disturbance chain A classification by chemical mineral composition:

1. Siliceous refractory cavity material 2, aluminosilicate refractory 3, magnesium refractory 4, dolomite product 5, chromium product 6, carbon product 7, zirconium product 8, special products.

A class of inorganic non-metallic materials with a refractory degree of not less than 1580. Refractory resistance refers to the Celsius temperature at which the refractory conical specimen resists high temperature without softening and melting without load.

However, the definition of refractory alone is no longer a complete description of refractories, and 1580 is not absolute. It is now defined as a material whose physical and chemical properties allow it to be used in a high-temperature environment, called a refractory material.

Refractories are widely used in metallurgy, chemical industry, petroleum, machinery manufacturing, silicate, power and other industrial fields, and are the largest in the metallurgical industry, accounting for 50% and 60% of the total output.

Refractory materials are used in various fields of the national economy such as steel, non-ferrous metals, glass, cement, ceramics, petrochemicals, machinery, boilers, light industry, electric power, military industry, etc., and are indispensable basic materials to ensure the production and operation of the above-mentioned industries and technological development, and play an irreplaceable and important role in the development of high-temperature industrial production.

Since 2001, under the strong pull of the rapid development of high-temperature industries such as steel, nonferrous metals, petrochemicals, building materials, etc., the refractory industry has maintained a good growth trend and has become a major producer and exporter of refractories in the world. In 2011, China's refractory production accounted for about 65% of the world's total, and its production and sales ranked first in the world.

Refractory refers to the inorganic non-metallic material with a refractory degree of not less than 1580.

Refractories should generally have good resistance to thermal shock and chemical attack, as well as low thermal conductivity and expansion coefficient, as well as physical indicators.

Refractories are widely used in metallurgy, building materials, chemical industry, petroleum, machinery manufacturing, silicate, power and other industrial fields, and are the largest in the metallurgical industry, accounting for 50 60 of the total output.

There are many types of refractory materials, which are usually divided into ordinary refractories (1580 1770), high-grade refractories (1770 2000) and special refractories (more than 2000) according to the level of refractoriness; According to chemical properties, it is divided into acid refractories, neutral refractories and alkaline refractories.

In addition, there are refractories for special occasions.

The definition of refractory is no longer limited to whether the refractory is above 1580.

At present, refractories generally refer to inorganic non-metallic materials used in the lining of metallurgy, petrochemical, cement, ceramics and other production equipment.
