Abstract

The invention discloses a super wear-resistant ceramic-steel composite lining plate for a mixer and a preparation method thereof. The composite lining plate comprises a metal base plate and a ceramic material layer, wherein a mixture of a ceramic material and an adhesive is pressed on a combining surface of the metal base plate by a pressing force, which is coated with the adhesive so that the ceramic material and the steel are compounded; the metal base plate is provided with a mounting bolt hole; and metal anchoring nails and reinforced ribs are distributed on the combining surface. The preparation method comprises four processes, namely a metal base plate manufacturing process, a ceramic material preparing process, a compounding process, a curing process and the like. The super wear-resistant ceramic-steel composite lining plate has rich raw material resources, simple process, low price and higher cost performance. After the super wear-resistant ceramic-steel composite lining plate is comprehensively constructed, the service life of the lining plate is prolonged by 10 to 15 times; the capital consumption is reduced by 50 percent; the maintenance and replacement time is shortened by over 90 percent; the utilization rate of equipment is improved by about 10 percent; labor intensity and production cost are reduced; human resources and materials are saved; and further potential economic benefit is brought to the society.

Description

technical field [0001] The invention is applicable to the field of wear-resistant parts of mechanical devices such as mixing and stirring, and mainly relates to a super wear-resistant ceramic-steel composite liner for a mixer and a preparation method thereof, and is especially suitable for metallurgy, glass manufacturing, refractory materials, thermoelectric , Mineral dressing, ceramics, chemical industry and other industries. Background technique [0002] At present, it is used as anti-wear parts such as lining boards on mixers and mixers in metallurgy, refractory materials, glass manufacturing, thermal power plants, mineral processing, ceramics, chemical industry and other industries. About 30,000 tons of high-quality wear-resistant steel are consumed every year, and the capital consumption is about 600 million yuan, which consumes a large amount of resources and funds, and also consumes a large amount of strategic materials such as precious metals, which does not conform ...
