Abstract
The utility model discloses a ceramic and metal composite wear-resisting milling disc of a coal mill. The ceramic and metal composite wear-resisting milling disc comprises a milling disc body (1) made of a high-chromium alloy, and is characterized in that a latticed ceramic pre-fabricated body (2) sintered by ceramic powder is arranged in the milling disc body (1) and is close to the upper surface of the milling disc body (1); a metal nickel layer (3) is plated on the surface of the ceramic pre-fabricated body (2); high-chromium alloy of the ceramic pre-fabricated body (2) is fused and then is poured into the milling disc body (1), and thus the ceramic pre-fabricated body (2) is integrated with the milling disc body (1). The ceramic and metal composite wear-resisting milling disc of the coal mill is simple in structure, low in manufacturing cost, good in wear resistance and long in service life, and is unlikely to drop off.
Description
Technical field
The utility model relates to a kind of coal pulverizer mill, particularly a kind of ceramet complex abrasion-proof coal pulverizer mill.
Background technology
Present medium-speed pulverizer mill (comprising HP, mps type etc.), the cast of general employing high-chromium alloy forms, in work because higher extruding force is born on surface, shearing force, General Life 8000-12000 hour, mill surface after wearing and tearing forms groove and waveform pit, needs to repair or change, and service life is short.At present, as Chinese patent 201020156757.7 also adopts the composite gridding at mill surface recombination high-chromium alloy and ceramic particle, such composite, in use, ceramic particle is prone to the phenomenon come off, and ceramic particle and high-chromium alloy adhesive property are bad, wear no resistance.Service life is still very short.
The utility model content
In order to solve the problems of the technologies described above, the utility model provides a kind of anti-wear performance good, the ceramet complex abrasion-proof coal pulverizer mill of difficult drop-off, long service life.
To achieve these goals, the technical solution of the utility model is as follows: a kind of ceramet complex abrasion-proof coal pulverizer mill, comprise the mill body (1) of being made by high-chromium alloy, it is characterized in that: the position near upper surface in mill body (1) is provided with the ceramic performs (2) formed with the ceramic powders sintering, described ceramic performs (2) is latticed, the surface of described ceramic performs (2) is coated with layer of metal nickel dam (3), described ceramic performs (2) is poured into after melting by high-chromium alloy in mill body (1) and becomes one with mill body (1).
Adopt technique scheme, composite ceramics metallic composite on the coal pulverizer mill, increase wearability, increases service life.Secondly, the ceramic performs that the utility model adopts the ceramic powders sintering to form, this ceramic performs is a complete sintered body, shock resistance is good, plating nickel on surface at ceramic performs, improve the cementability between ceramic performs and high-chromium alloy molten metal, make in use, ceramic performs not there will be the phenomenon come off.Long service life.
In technique scheme: the thickness of described ceramic performs (2) is 10-40mm.
In technique scheme: the thickness of described metal nickel dam (3) is 10-200um.Cementability between ceramic performs and high-chromium alloy molten metal is good like this.
Beneficial effect: the utility model is simple in structure, low cost of manufacture, and wearability is good, and long service life is not prone to and comes off.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
The A-A cutaway view that Fig. 2 is Fig. 1;
The cutaway view that Fig. 3 is the utility model ceramic performs.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Claims (3)
