Abstract
The utility model relates to a liner plate for a medium-speed mill. The liner plate for the medium-speed mill comprises a liner plate main body, wherein a ceramic grain layer is compounded on the surface of the liner plate main body. The ceramic grain layer is strengthened by using high chromium alloy, so that the ceramic grain layer is uniformly distributed in the liner plate main body; the abrasion resistance of a ceramic material and the mechanical property of a cast alloy can be organically combined, so that in a working process of three-body abrasion, the whole structure has high abrasion resistance and sufficient impact strength; therefore, compared with the prior art, the liner plate for the medium-speed mill has the advantages that the service life is prolonged by 2-4 times, and the using requirements of the medium-speed mill on the abrasion resistance can be met.
Description
Technical field
The utility model relates to the wear-resisting equipment that in industries such as electric power, cement, chemical industry and iron and steel, uses, and is specifically related to a kind of medium-speed pulverizer liner plate.
Background technology
At present, medium-speed pulverizer generally uses in industries such as electric power, cement, chemical industry and iron and steel as wear-resisting equipment commonly used, and the high-abrasive material that original medium-speed pulverizer liner plate adopts has four types: potassium steel, the hard IV alloy of nickel, high-chromium alloy, surface overlaying.Though from four types of the first kind to the; Its material hardness is increasingly high; Anti-wear performance also improves gradually; But the danger of its fragility, fracture also increases greatly simultaneously, thereby how to select not only have high-wear resistance but also can prevent that the material that ruptures from becoming the important decisive factor of decision medium-speed pulverizer liner plate high-abrasive material.
The utility model content
The utility model provides in order to overcome the above problems that a kind of shock resistance, anti-wear performance are good, the medium-speed pulverizer liner plate of long service life.
The technical scheme of the utility model is: comprise the liner plate main body, described liner plate body surfaces is compounded with the ceramic particle layer.
Described ceramic particle layer is the inter-adhesive network structures that form of some ceramic particles.
The thickness of described ceramic particle layer is 25-50mm.
Described liner plate main body is a high-chromium alloy.
The utility model utilizes high-chromium alloy to reinforce the ceramic particle layer; Make it to be distributed in uniformly in the liner plate main body; The wearability of ceramic material and the mechanical performance of high-chromium alloy are organically combined; Total has higher anti-wear performance and enough impact strengths in trisome abrasive wear operating mode, make prolong 2～4 times on the original basis the service life of medium-speed pulverizer liner plate, can satisfy the instructions for use of medium-speed pulverizer to anti-wear performance.
