High-strength wear-resistant anti-erosion pouring material
The invention discloses a high-strength wear-resistant anti-erosion pouring material. The high-strength wear-resistant anti-erosion pouring material is prepared from, by weight, 30%-40% of skeletal materials, 50%-60% of carborundum powder and alumina micro powder, 1%-2% of steel fibers, 3%-5% of porcelain powder, 3%-5% of potassium feldspar, sodium tripolyphosphate and bonding agents, wherein the skeletal materials comprise sub-white corundum particles with the particle sizes of 1-3 mm, 3-5 mm, 5-8 mm and 8-12 mm respectively, the porcelain powder comprises 20-80 parts by mass of SiO2 and 10-50 parts by mass of AlF3, the sodium tripolyphosphate accounts for 0.15%-0.20% the total weight of the skeletal materials, the carborundum powder and alumina micro powder, the steel fibers, the porcelain powder and the potassium feldspar, and the bonding agents account for 7%-10% o the total weight of the skeletal materials, the carborundum powder and alumina micro powder, the steel fibers, the porcelain powder and the potassium feldspar. According to the working conditions of special parts of a cement kiln, the damage mechanism of tertiary air duct materials is researched, and the high-performance chemically combined wear-resistant anti-erosion pouring material is developed. Chemical reactions are gradually conducted in the use process of the pouring material, and the pouring material has the advantages of being high in wear resistance, good in acid resistance and long in service life. Construction of the pouring material is convenient and rapid, the pouring material can be used by adding the bonding agents through on-site stirring, the use requirements can be met by means of manual pouring and simple maintenance, and the average service life can reach above two years.
