Abstract
The invention provides a method for improving the wear resistance of a wear-resistant part of an extruding machine so as to meet the requirement for manufacturing of wear-resistant parts of building material machines. According to the method for improving the wear resistance of the wear-resistant part of the extruding machine, a wear-resistant alloy powder block is subjected to arc surfacing and fusing on the surface of the part through a direct-current welding machine, so that a wear-resistant layer is formed on the surface of the part. An extruding machine part manufactured according to the method has the advantages that the wear-resistant layer formed on the surface is thick, and the service life of the part is greatly prolonged since the alloy block is solidly bonded with the surface of the part after being fused; meanwhile, the arc surfacing process is easily combined with the wear-resistant layer process, and product cost is lowered greatly.
Description
Technical field
The invention belongs to sintering walling production field, particularly extruder wearing piece production technology.
Technical background
In recent years, along with national wall changes the further propelling of policy, one with " to prohibit real limit sticky, energy-conservation system is useless " be the wall reform of purport, the brick-tile industry of Yi China is in full swing.Gangue, hard shale, mine tailing, industrial residue have been widely used in sinter walling materials.These materials belong to hard material, require in process of production machinery equipment will have very high-wearing feature and life-span, and wear-resisting, the wear resistence that improve equipment wearing piece have and important meaning.
The brickmaking of gangue the like waste can be energy-conservation, save land and protection of the environment, turn harm into good, to energy-saving and emission-reduction, develop a circular economy significant.Due to these hard material particularity, brickmaking production technology will be very high when extrusion molding extrusion pressure, low moulding moisture content, increased the frictional force of pug to body, wearing piece wear extent is strengthened, require wearing piece will have enough wearabilities, guarantee is produced and is normally carried out and frequently do not change consumable accessory, therefore the Wear Resistance to wearing piece, adopts new high-abrasive material to have important meaning.According to industry statistic, brick machine wearing piece reamer for example, tradition has several forms: steel plate weldering is done, casting white iron, spraying carbide.These several Design and materials are all undesirable, and general production standard brick 200～3,000,000 need to change repairs reamer, and body is damaged.And the never wear-resisting problem of alloy powder block built-up welding reamer energy efficient solution can realize and produce 800～1,000 ten thousand blocks of standard bricks, again repair reamer, do not injure reamer body.
At building material industry, improving part wearability has following several way at present: 1, and adopt antifriction alloy to make privileged sites part, because antifriction alloy price is high, and building material machinery is generally bulky, causes product cost very high.2, adopt surface spraying alloyed powder mode, although this mode has been saved cost, because wearing layer is thinner, extrude raw material harder, wearing layer can be come off very soon, service life is shorter.
Summary of the invention
The object of the invention is to provide a kind of method that improves extruder wearing piece anti-wear performance, to meet the manufacture of building material machinery wear part.
The method that improves extruder wearing piece anti-wear performance, it adopts dc welding machine at piece surface arc surfacing, melting abrasion-resistant alloy cake, at piece surface, forms wearing layer.
Adopt and lengthen soldering turret, welding current 200～300A, overlay cladding dilution rate 50%; Surface forms wearing layer Rockwell hardness HRC >=56, and wearing layer thickness surpasses 5mm.
The extruder part that the inventive method is manufactured, surface abrasion resistance layer thickness is thick, and is combined with piece surface firmly after alloy block melting, has greatly improved part service life.The technique of arc surfacing simultaneously complex abrasion-proof layer process is simple, and product cost reduces greatly.
The specific embodiment
Take at screw reamer surface recombination wearing layer is example.
1, adopt dc welding machine (just connect, carbon-point connects negative pole, use direct current carbon-point), manual electric arc pile up welding, melting.Adopt and lengthen soldering turret, welding current 200～300A, overlay cladding dilution rate 50%.
2, main material specification:
Abrasion-resistant alloy cake 90 * 30 * 4mm
Graphite electrode specification Φ 10 * 300mm
Single-layer surfacing layer has hypereutectic tissue, Rockwell hardness HRC >=56, and layer thickness reaches 5mm, and postwelding improves service life of equipment 8-10 doubly, and extruder reamer can production standard brick more than 1,200 ten thousand.
Claims (2)
1. improve the method for extruder wearing piece anti-wear performance, it is characterized in that adopting dc welding machine at piece surface arc surfacing, melting abrasion-resistant alloy cake, at piece surface, form wearing layer.
2. improve according to claim 1 the method for extruder wearing piece anti-wear performance, it is characterized in that adopting lengthening soldering turret, welding current 200～300A, overlay cladding dilution rate 50%; Surface forms wearing layer Rockwell hardness HRC >=56, and wearing layer thickness surpasses 5mm.
