Problems solved by technology

[0010] The binder of the converter large surface repairing material is one of the main factors determining its fluidity and bonding strength. The existing technology generally uses pitch-bonded magnesia-carbon repairing materials, but because the thermal decomposition and polymerization of the pitch take a long time, Therefore, the sintering repairing t

Abstract

The invention relates to a converter repairing material and a production method thereof. The converter repairing material is prepared from the following raw materials in parts by weight: 73-100 parts of 200-mesh dead burnt magnesia, 20-30 parts of 1-3 mm macrocrystalline fused magnesite, 20-30 parts of 200-mesh macrocrystalline fused magnesite, 2-5 parts of metal aluminum powder, 2-5 parts of zirconium oxide powder, 2-5 parts of magnesium aluminate spinel, 2-4 parts of calcite powder, 2-4 parts of potassium feldspar powder, 3-5 parts of forsterite powder, 5-10 parts of asphalt, 5-8 parts of sodium oleate and 5-12 parts of magnesium trisilicate. The environment pollution caused by the asphalt is reduced, the characteristics of good high-temperature fluidity and good spreadability of the asphalt are retained, the sintering time is short, and the bonding strength is high. The converter repairing material can be suitable for pouring operation of molten steel with relatively low alkalinity and also can be suitable for pouring operation of molten steel with relatively high alkalinity. The converter repairing material has the advantages of good fluidity, high density, short sintering time and long service life.

Description

technical field [0001] The invention relates to the technical field of refractory production, in particular to a converter repair material and a production method thereof. Background technique [0002] The furnace age of the converter is an important technical and economic index in the converter steelmaking, and it is an important factor for the steelmaking plant to exert its benefits. Increasing the furnace life of the converter can not only improve the production efficiency of the converter, reduce the consumption of refractory materials, ensure the operation rate of the continuous casting machine, but also give full play to the comprehensive benefits of the blast furnace, steelmaking, steel rolling and other systems. [0003] The converter slag splashing protection technology is one of the most important technological innovations in the converter steelmaking production process in the past ten years. Due to the popularization and popularization of this technology, the fur...
