Yingkou City organized more than 100 enterprises of refractory materials, equipment manufacturing and building materials to hold talks

In order to improve the supporting capacity of large and medium-sized enterprises in Yingkou, promote the internal circulation of industrial products in Yingkou, and strengthen the leading industry chain, Yingkou Bureau of industry and information technology organized a meeting of large and medium-sized enterprises in Yingkou on the morning of September 24.

Reuse of waste refractories

The consumption of various refractories in China is increasing day by day, and the proportion of used refractory materials has reached 45% of the total consumption of refractory. However, the role of so many waste refractory materials in a long time is landfill waste, which not only causes waste of resources, but also causes irreversible pollution to the environment.

Selection of refractories for carbon calciner

Carbon calciner is a kind of heat treatment equipment for carbon materials, including rotary type and autoclave type. The selection of refractories for the two furnace types is also different.

What are the five most common classifications of refractories?

At present, the most common classification of refractory materials is chemical composition classification, which can be divided into silica, aluminosilicate, magnesium, dolomite and carbon composite.

Refractory materials used for blast furnace tapping and slag chute

Because of the bad working conditions of the cast iron ditch of blast furnace, it is directly washed by hot metal, so it is seriously damaged. In the selection and application of refractory materials for tap hole, it is necessary to have high temperature resistance, wear resistance, high temperature slag resistance, thermal shock resistance and oxidation resistance. On this basis, the following problems should be considered comprehensively: the particle size of sintered or fused alumina should be more than 1.5mm,

Refractory materials commonly used in blast furnace tapping and tapping ditch

Taphole is the throat of hot metal discharged from blast furnace. Due to the large-scale blast furnace and the adoption of intensified smelting technology, the times of tapping increase, so its working conditions become more severe.
