Problems solved by technology

However, most of the construction of unshaped refractory materials is carried out by casting. The disadvantage of the existing technology is that the construction surface with a large angle and inclination is not conducive to the construction of castables. If construction is required, additional assistance such as molds is required. The equipment is pouring construction, and the material is prone to cracking and peeling after high temperature

preparation example Construction

[0045] The second aspect of the present invention provides the preparation method of the kiln coating material according to the first aspect of the present invention. Those skilled in the art can choose a suitable method, by applying the additive-added kiln coating material according to the first aspect of the present invention. The formulation of the material is prepared to obtain a kiln coating material with admixtures added. For example, the preparation method may be physical mixing, and may specifically include: kneading each component with the formula provided in the first aspect of the present invention. More specifically, the coke gemstone, bauxite powder, alumina powder, silicon micropowder, binder, kyanite, water reducing agent, coagulant, anti-explosion agent, and gel-promoting admixture are mixed and kneaded to prepare the obtained product. The kiln spreads with admixtures are described. The kneading time may be, for example, 170-200 seconds, 170-180 seconds, 180-1...

Abstract

The invention relates to the technical field of metallurgy, in particular to a coating material for a furnace kiln and a preparation method and application thereof. The coating material for the furnace kiln is prepared from the following raw materials: flint clay, alumina powder, alumina powder, silica powder, a binding agent, kyanite, a water reducing agent, a coagulation accelerator, an anti-explosion agent and a gelation accelerating additive. The construction form of the coating material can be changed according to the construction site of the furnace and kiln and different construction requirements, one material can meet the requirements of various construction operation modes, and the use requirements of the furnace and kiln can be met due to the excellent performance of the coating material. The material prepared by the method still has the advantages of good melt or gas erosion resistance, good smearing property, good adhesiveness with a protected material, good thermal shock stability and chemical stability, difficult cracking in use and long service life.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a kiln coating material and a preparation method and application thereof. Background technique [0002] Refractory smears are generally used to make linings when the use temperature is low, the structure is complex and the lining is thin, or when the use temperature is high and there are special requirements, refractory smears are often used to make coatings. However, most of the construction of unshaped refractory materials is carried out by casting. The disadvantage of the existing technology is that it is not conducive to the construction of castables for construction surfaces with large angles and inclinations. For construction, additional aids such as molds are needed The equipment is used for pouring construction, and the material is prone to cracking and peeling after high temperature. SUMMARY OF THE INVENTION [0003] In view of the above-mentioned shortcomings of t...
