When naturally cooling to 500-1000 ℃, smash sand mold, carry out the air heat of cooling again and handle, increase hardness fast; Clean out support, set bolt then, remove cast gate, cap mouth, overlap, burr etc., become antiwear lining plate with embedded hard alloy.
The composition of antiwear lining plate with embedded hard alloy comprises the liquid metal of carbide alloy wear-resistant block and casting, the liquid metal of casting is full of the shape locking space of carbide alloy wear-resistant block, become the matrix material of liner plate, hard alloy blocks and matrix material are inlayed, are cast in and constitute liner plate together.
The liquid metal of casting comprises abrasion resistant cast steel or wear resistant cast iron etc.The shape in the shape locking space of carbide alloy wear-resistant block is arbitrarily.
The surface configuration of carbide alloy wear-resistant block and size are arbitrarily on the liner plate, and preferable shape is hexagram or circle.
Adopt the present invention, because hard alloy blocks constitutes liner plate by casting with abrasion resistant cast steel or wear resistant cast iron embedding together, good impact resistance, wearability and heat-resisting quantity are all very high, there is not continuous soft band, do not consume non-ferrous metal, do not need the machined of assisting, cost is low, long service life.
The present invention has that technology is reasonable, method is novel, cost is low, the characteristics of long service life, has improved impact resistance, wearability and the heat-resisting quantity of liner plate, is applicable to fragmentation, screening, carrying, storage, the conveying of various industrial bulk cargos.
