Abstract
The invention discloses a high-strength wear-resistant anti-corrosion brick and a manufacturing method thereof, and belongs to the field of refractory materials. The high-strength wear-resistant anti-corrosion brick comprises the following raw materials in parts by weight: 50-100 parts of bauxite, 5-20 parts of chromium concentrate, 1-10 parts of metallic silicon submicron powder and 1-10 parts of kaolin. The high-strength wear-resistant anti-corrosion brick is prepared by successively performing burdening, mulling, molding, drying and sintering. The high-strength wear-resistant anti-corrosion brick provided by the invention not only is simple in production technology and moderate in cost, but also is good in usage performances, and the service life of the high-strength wear-resistant anti-corrosion brick in a high-temperature segment of a laterite-nickel ore rotary kiln employing a direct reduction technology is up to one year or more, so that the production cost of a nickel iron enterprise is substantially reduced, the comprehensive energy consumption is reduced, the user requirements are completely exceeded, and impressive economic benefit is obtained.
