Description of drawings
Below expressed content of the accompanying drawing of this specification and the mark among the figure are briefly explained:
Fig. 1 is a cross-sectional view of the present utility model.
Be labeled as among the figure:
1, build-up wear-resistant layer, 2, general steel plate.
The specific embodiment
Contrast accompanying drawing below,, the specific embodiment of the present utility model is described in further detail, inventive concept of the present utility model, technical scheme are had more complete, accurate and deep understanding to help those skilled in the art by description to embodiment.
The of the present utility model structure expressed as Fig. 1, the utility model is a kind of wear-resistance composite board of metal machine part and renovation technique thereof, adopts general steel plate 2 as agent structure, on the surface of described general steel plate 2, is provided with one deck build-up wear-resistant layer 1.
The material of build-up wear-resistant layer 1 described in the utility model is the hypereutectic high-chromium alloy.High-chromium alloy hardfacing composite plate is a kind of novel high abrasion composite, and it is to adopt automatic metal arc surfacing new process, forms hypereutectic high-chromium alloy wear-resisting layer on Q235 or 16Mn view picture steel plate.
The material of above-described general steel plate 2 is Q235 or 16Mn.Weld on the common steel plate of Q235 or 16Mn, cost is low, but can satisfy wear-resisting performance.The hardfacing clad steel plate can cold roll forming, the volume circle, available plasma patterning method cutting, can be easily with the wear-resistant composite board welding at the surface of the work that is worn.
Be the renovation technique of wear-resistance composite board of metal machine part below, the concrete technical scheme of described renovation technique is:
Described renovation technique adopts bead-welding technology, promptly adopts the method for metal arc built-up welding, the hypereutectic high-chromium alloy is welded on equably on the surface of general steel plate 2, forms described build-up wear-resistant layer 1.
Above-described bead-welding technology adopts welding gun back and forth operation in the horizontal direction, general steel plate 2 is along doing feed motion with the perpendicular direction of the reciprocal traffic direction of welding gun, on the surface of general steel plate 2, form back and forth parallel multiple tracks welding bead, closely seamless and fuse into one between the welding bead, and then on the surface of general steel plate 2, form overlay cladding fine and close, consistency of thickness.
Electric current I 〉=the 400A of described bead-welding technology; Voltage U 〉=27.5V.
The width of described welding bead is 28 ± 2mm.
