Abstract
The utility model relates to a dual-metal roller for coal mills, which is a component of machinery equipment. The roller is composed of a base substrate (1) and a protective layer (2), wherein, the protective layer adopts the hard alloy material of boron, vanadium and chromium. The utility model has the advantages of favorable abrasive resistance, easy production and low cost, and the roller can be repaired and reused after worn out.
Description
The utility model relates to a kind of parts coal pulverizer bimetallic roller tire of plant equipment.
At present, the coal pulverizer that the pulverizing coal is used is used for thermal power generation department in a large number, and coal pulverizer roller tire adopts the nickel chromium triangle casting to make usually.This coal pulverizer roller tire wears no resistance, and the machine-shaping difficulty can not be repaired use, the cost height after the wearing and tearing of roller tire again.
The purpose of this utility model is the deficiency that will overcome above-mentioned technology, and the coal pulverizer bimetallic roller tire of built-up welding boron-vanadium-chrome carbide alloy on a kind of roller fetus body of expecting to make in the medium carbon steel village is provided.Roller tire wearability is good, and machine-shaping easily can be repaired use after the wearing and tearing of roller tire again, reduces cost.
The utility model can be achieved through the following technical solutions:
Coal pulverizer bimetallic roller tire is protective layer (2) formation by idiosome (1) and idiosome (1) outer surface.The thickness of protective layer (2) is 5～30 millimeters, and protective layer (2) adopts Hardmetal materials, has improved roller tire wearability.Protective layer (2) is the outer surface of built-up welding in idiosome (1), re-uses after the reparation of pile-up welding hard alloy material again after the wearing and tearing.
Below in conjunction with accompanying drawing structure of the present utility model is described:
Fig. 1 is the front view of roller tire;
Fig. 2 is the A-A cutaway view among Fig. 1.
As shown in Figure 1, coal pulverizer bimetallic roller tire is made up of idiosome (1) and protective layer (2).
Be described further below in conjunction with embodiment:
The idiosome (1) of coal pulverizer bimetallic roller tire adopts mild steel material, and it respectively is B1.5 that protective layer (2) adopts degree, the boron-vanadium-chrome Hardmetal materials of V11, Cr5.Can continue the reparation of built-up welding boron-vanadium-chrome Hardmetal materials after protective layer (2) wearing and tearing re-uses.
The outstanding advantage of the utility model Dual-metal roller for coal mill is that roller tire wearability is good, and easily machine-shaping can be repaired after the wearing and tearing of roller tire and re-used, and cost is low.
Claims (3)
1, a kind of parts coal pulverizer bimetallic roller tire of plant equipment is characterized in that: the roller tire be by idiosome (1) and idiosome (1) appearance protective layer (2) constitute.
2, roller tire according to claim 1 is characterized in that protective layer (2) adopts the boron-vanadium-chrome Hardmetal materials.
3, roller tire according to claim 1, the thickness that it is characterized in that protective layer (2) is 5～30 millimeters.
