Abstract
Metal sieve plate preparation method with build-up wear-resistant layer.It has changed in the past earlier at surface of steel plate built-up welding one deck antifriction alloy, go out the method for sieve aperture then with plasma arc cutting, but earlier on steel plate, process sieve aperture, with resistant to elevated temperatures nonmetal cream sieve aperture is filled and led up, again with electric arc or plasma arc with the antifriction alloy built-up welding on the surface of steel plate with holes.This method can be saved the antifriction alloy 30% of built-up welding or more.This metal sieve plate is used for the rotary screen of sorting ore and other need bear the equipment of the sieve plate of abrasive wear.
Description
The present invention relates to a kind of improved preparation method with metal sieve plate of build-up wear-resistant layer.
By document retrieval and investigation both at home and abroad, in the world, for example West Germany, Australia, the U.S. and Canada, make the method for the metal sieve plate of build-up wear-resistant layer, all be first, on the steel plate after the built-up welding, cut out sieve aperture with plasma arc size in accordance with regulations then at surface of steel plate built-up welding one deck antifriction alloy.Process sieve aperture in this way, waste build-up wear-resistant alloy, and also the processing in hole is relatively more difficult.Still the unit of finding no or individual making have the metal sieve plate of build-up wear-resistant layer at home.
For saving the antifriction alloy of built-up welding, reduce cost, the making of built-up welding has the method for the metal sieve plate of wearing layer behind spy's invention elder generation processing sieve aperture.
The present invention is achieved in that and processes sieve aperture earlier on steel plate, can be circular hole, and diameter is 5～30 millimeters, also can be strip hole, and width is 3～30 millimeters.Be equipped with the high temperature resistant nonmetal cream that 3～5% waterglass makes with casting with Modeling Material then sieve aperture filled and led up, again with electric arc or plasma arc, preferably by hand carbon arc or carbon electrode air plasma arc with the antifriction alloy built-up welding on the surface of steel plate with holes.Liquid metal with the corresponding position of sieve aperture in the surfacing layer metal molten bath forms eyelet automatically before solidifying.Antifriction alloy can be iron-based, Ni-based or cobalt-base alloys, preferably high carbon and chromium sections based wear-resistant alloy powder agglomates.
The invention has the advantages that, the first, process sieve aperture earlier, the method for back build-up wear-resistant layer can be saved antifriction alloy 30% or more; The second, the machining hole ratio is easier on the steel plate of build-up wear-resistant layer not, the efficient height, and alternative processing method is also many.
