Abstract
Fe-05 surfacing welding alloy powder agglomates is a kind of resurfacing welding material that is used to bear the surface of the work of low stress abrasive wear.The Fe-05 powder agglomates adopts some kinds of mechanical crushing powders and the atomized powder back that proportions to add quantitative bonding agent and be formed after mixing, repression.The Fe-05 powder agglomates belongs to the chromium base, and its alloy content is: C:5～6.5%; Cr:48～52%; B:3～4%; Si:3～4%; Ni:2～3%; Fe:33.5～39%.With arc-welding or plasma welding heat source, be with or without under the protection against oxidation condition, all can be on the surface of the work of steel the Fe-05 powder block surfacing.
Description
The present invention relates to a kind of improved hardfacing materials and preparation method thereof.
By literature search and investigation both at home and abroad, recognize that it is the atomized alloy powder of representative that existing resurfacing welding material has with Switzerland Castolin company from form, metallurgy cast alloy cast block and the paste alloy powder that Britain's coal system adopts and silk, rod, band, the tubulose hardfacing alloy that generally adopts of Soviet Union's crust institute of welding research arranged.In the surfacing welding alloy of above-mentioned various forms, affiliated alloy system is iron-based, Ni-based, cobalt-based etc.But producing of atomized alloy powder needs special melting spray equipment, and 80% the highest acquisition amount can only be arranged, and 10% windage arranged again during use and need special dust feeder.The metallurgical casting piece need increase once metallurgical casting process.Operation such as the paste alloyed powder needs in-place coating in use, dry.Silk, rod, band, tubulose resurfacing welding material are difficult to realize the high alloy content of resurfacing welding material again.
Can the simplified manufacturing technique process for producing, reduce the material manufacturing cost, easy to use, the hardfacing materials that has high-wearing feature and high economic benefit again, special invention Fe-05 surfacing welding alloy powder agglomates.
Fe-05 surfacing welding alloy powder agglomates raw material is a high carbon ferro-chrome 60～80%; Ferro-boron 15～35%; The Mechanical Crushing powder of ferrosilicon 2% and 102Fe atomized powder 3%, it belongs to the chromium-base alloy system.Its alloying component is C:5～6.5%; Cr:48～52%; B:3～4%; Si:3～4%; Ni:2～3%; Fe:33.5～39%.The preparation method of Fe-05 powder agglomates is that raw material are broken into powder with machining process, and granularity prepares even mixing in proportion less than 50 orders, adds the waterglass bonding agent that accounts for powder weight 5～15%, forms loose granular alloy.Then will this granular alloy in accordance with regulations weight be filled into and impose every square centimeter of pressure more than 500 kilograms in the mould, form bulk alloy, remove behind the moisture content finished product.The geometry of this alloy block and size are decided according to built-up welding area, shape of product and overlay cladding thickness, can make shapes such as curved surface, plane, straight flange, Qu Bian.Powder agglomates adopts welding and method of superposition can realize any area and the thickness of product needed built-up welding.
It is low that the Fe-05 powder agglomates has cost of manufacture, and no metallurgy and casting process do not need special dust feeder during use, need not coating and dry process on workpiece, characteristics such as the lost phenomenon of alloy-free.Metallographic structure after the built-up welding reaches at 60% o'clock in dilution rate, is still to contain the once eutectic structure of carbon chromium compound, and effective wear-resisting thickness is bigger.The Fe-05 powder agglomates can utilize arc-welding or plasma welding heat source, all can weld being with or without under the protection against oxidation condition.
Realize that best way of the present invention is to adopt the carbon arc bead-welding technology, on the middle-low alloy steel of thickness more than 6 millimeters, carbon steel steel plate or the enterprising windrow weldering of the surface of the work that bears low stress abrasive wear of forged steel, cast steel.With 15 millimeters of diameter phi 10～φ, long 30～300 millimeters graphite rods or carbon-point are done electrode, and arc-welding machine is done power supply and carried out built-up welding.Can be placed on surfacing part to the Fe-05 powder agglomates of definite shape size according to the requirement of workpiece before the built-up welding, with carbon arc it is deposited on the surface of the work then, form wearable overlay.In addition, adopt plasma arc or tungsten argon arc thermal source can also realize the automation built-up welding.
