Abstract
The invention discloses a screw conveyer blade with an abrasion-resistant coating. The blade is of a sector structure and is spatial warping or plane-shaped. The blade is spirally arranged on a rotation shaft; a working side surface and/or an arc top surface of the blade is covered with an abrasion-resistant coating; and the abrasion-resistant coating is sprayed by adoption a powder plasma spray welding process and uses alloy powder as a filling material. The screw conveyer blade can overcome the defects of blades made of the conventional abrasion-resistant steel materials, and has excellent high temperature abrasion-resistant performance; and the service life of the blade is prolonged, and the conveying of materials can be ensured in a high temperature environment.
Description
Technical field
The present invention relates to a kind of conveying worm blade with wear-resistant coating.
Background technology
For transmitting the conveying worm of material, material is conveyed by the helical blade that rotarily drives of helical axis, it may operate in normal temperature environment and also can run on hot environment to convey high-temperature material.During material transferring, due to directly contact between material and helical blade, blade is subject to the strong abrasive wear of material to act on it is easy to lose efficacy because of abrasion.For avoiding the abrasion of blade; blade would generally be made using some wear-resisting steel grade materials; but its using effect is not satisfactory; particularly in nearly 800～900 DEG C of hot environment; the hardness of wear-resisting steel grade material can greatly reduce; it is easy to be worn and lost efficacy, reduce the service life of blade, the conveying of material in impact hot environment.
Content of the invention
The technical problem to be solved is to provide a kind of conveying worm blade with wear-resistant coating, this blade overcomes the defect that traditional wear-resisting steel grade material makes blade, there is good wear resistance at elevated temperature, greatly improve the service life of blade it is ensured that in hot environment material transmission.
For solving above-mentioned technical problem, the present invention has the conveying worm blade of wear-resistant coating, described blade shape is sector structure and carrying space distortion or flat shape, described blade is twist located at rotating shaft, the work side surface of described blade and/or arc top surface are provided with wear-resistant coating, and described wear-resistant coating is sprayed using powder plasma spray welding process and using alloy powder as packing material.
Further, described alloy powder is the Co-based alloy powder containing 60wt% tungsten carbide.
Further, described alloy powder is the mixed-powder of Ni based alloy powder and WC particle, and wherein mass percent in mixed-powder for the WC particle is 15～70%.
Further, the thickness of described wear-resistant coating is 3～5mm.
Because the conveying worm blade that the present invention has wear-resistant coating employs technique scheme, it is that this blade shape is sector structure and carrying space distorts or flat shape, described blade is twist located at rotating shaft, the work side surface of described blade and/or arc top surface are provided with wear-resistant coating, and described wear-resistant coating is sprayed using powder plasma spray welding process and using alloy powder as packing material.This blade overcomes the defect that traditional wear-resisting steel grade material makes blade, has good wear resistance at elevated temperature, greatly improve the service life of blade it is ensured that in hot environment material transmission.
Brief description
The present invention is described in further detail with embodiment below in conjunction with the accompanying drawings：
Fig. 1 has the conveying worm blade construction schematic diagram of wear-resistant coating for the present invention；
Fig. 2 is the schematic cross-section of this blade.
Specific embodiment
Embodiment is as depicted in figs. 1 and 2, the present invention has the conveying worm blade of wear-resistant coating, described blade 1 is shaped as sector structure and carrying space distortion or flat shape, described blade 1 is twist located at rotating shaft 2, the work side surface of described blade 1 and/or arc top surface are provided with wear-resistant coating 3, and described wear-resistant coating 3 is sprayed using powder plasma spray welding process and using alloy powder as packing material.
Preferably, described alloy powder is the Co-based alloy powder containing 60wt% tungsten carbide.
Preferably, described alloy powder is the mixed-powder of Ni based alloy powder and WC particle, and wherein mass percent in mixed-powder for the WC particle is 15～70%.
Preferably, the thickness of described wear-resistant coating 3 is 3～5mm.
This blade, by the use of plasma arc as high temperature heat source, using alloy powder as packing material, by the cooperation of each technological parameter, finally forms, in the work side surface of blade and/or arc top surface, the deposition coating that high-quality smooths.Wherein to have self-fluxing nature, wettability and a surfacing excellent for Co-based alloy powder, and fusing point ratio is relatively low, and spray-welding coating has the characteristics that hardness is high, anti-corrosion, wear-resisting, heat-resisting；WC particle has high-melting-point, high rigidity, good stability, and with iron and steel complete wetting, with perfect adaptation, and can be readily available；Therefore this coating not only has very high hardness and excellent anti-wear performance under room temperature, and equally has good wear resistance at elevated temperature.This vanes practical application, operating temperature be 800～900 DEG C running environment under, blade run half a year still intact, therefore greatly improve the service life of blade it is ensured that in hot environment material transmission.
