Abstract
The utility model relates to a wear-resistant lining board for a ball mill. The utility model is composed of a lining board basal body and metal blocks which are coated at the convex surface or the easily wearing position of the lining board basal body. The hidden trouble that cracks are generated between the lining board basal body and silver blocks can be avoided, the product quality is increased, and the defective index is reduced. Meanwhile, the heat treatment can be smoothly carried out, and the conditions for fully exerting the properties of the shock resistance, the wear resistance and the corrosion resistance of the lining board are created.
Description
The utility model relates to a kind of ball mill wearing liner plate, is specially adapted to shock resistance, wear-resistant, corrosion-resistant liner plate that ore grinding is used.
Down, liner plate can be subjected to abrading-ball and abrasive wear to ball mill in working order.Wearing and tearing are processes of a complexity, are the main causes that causes liner plate to lose efficacy.At present, many factories all select for use potassium steel to make liner plate.As everyone knows, potassium steel is under non-intense impact, and its work hardening capacity can not given full play to, and case hardness is low, and abrasion resistance properties is poor.And high manganese steel lining plate in use, and plastic flow easily takes place, and causes changeing difficulty.So under some working condition, high manganese steel lining plate has not fitted into the needs of production.CN2109910V has issued the ball mill wearing composite liner.It is by wear-resistant, corrosion resistant rich chromium cast iron iron chains piece and the good medium carbon structural alloy steel basic composition of impact flexibility.Its shortcoming is and since the iron chains piece simultaneously be exposed to cast(ing) surface and and the shrinkage factor of two kinds of metals of matrix inequality, casting stress is big, easily cracks between iron chains piece and matrix.When serious liner plate is scrapped.Especially bring difficulty to heat treatment, programming rate and cooling rate are wayward, strengthen the expansion of former casting crack easily, and produce new crackle.
The purpose of this utility model is to overcome the weak point in the background technology, and provides a kind of rational in infrastructure, the ball mill wearing liner plate that is difficult for cracking in casting and heat treatment process.
The purpose of this utility model is achieved in that at liner plate matrix convex surface or position easy to wear places metal derby, and the liner plate matrix is fully with its coating.
The purpose of this utility model can also reach by following measure: the matrix adopting steel alloy of liner plate, metal derby adopts rich chromium cast iron or carbide alloy.
But the metallographic structure of refinement matrix behind the placement metal derby in the liner plate matrix, improved hardness, increased wearability, can prevent, eliminate generation shrinkage cavity of liner plate convex surface position and shrinkage porosite, particularly the foundry goods condensation rate is tending towards homogeneous, casting stress is little, is difficult for cracking, and has brought convenience to heat treatment.
The utility model is compared with background technology has following advantage:
1, avoids the hidden danger that cracks between liner plate matrix and the metal derby (iron chains piece), improved the quality of product, reduced percent defective.
2, because metal derby (iron chains piece) is coated by the liner plate basic material, therefore, heat treatment can be carried out smoothly, for the shock resistance of giving full play to liner plate, wear-resistant, corrosion resistant characteristic have been created condition.
Below in conjunction with (accompanying drawing) embodiment, the utility model is described in further detail:
Accompanying drawing is a structural representation of the present utility model, liner plate matrix (1), metal derby (2).
Embodiment 1:
Earlier cast out metal derby (2), by designing requirement, put it in the liner plate casting mold behind the clean surface with rich chromium cast iron, last, melted alloy molten steel is cast in the casting mold, make metal derby (2) and liner plate matrix (1) be shaped to one.
Embodiment 2:
According to the method for embodiment 1, the material of metal derby (2) can change carbide alloy into.
Claims (2)
1, a kind of ball mill wearing liner plate is characterized in that: at liner plate matrix convex surface or position easy to wear, place metal derby, the liner plate matrix is fully with its coating.
2, ball mill wearing liner plate according to claim 1 is characterized in that: the matrix adopting steel alloy of liner plate, metal derby adopts rich chromium cast iron or carbide alloy.
