Abstract
Fe-05 surfacing welding alloy powder agglomates of the present invention is a kind of resurfacing welding material be used to the surface of the work that bears low stress abrasive wear.This powder agglomates is to proportion with the Mechanical Crushing powder of high carbon ferro-chrome, ferro-boron, ferrosilicon and 102Fe atomized powder to add quantitative bonding agent and be formed after mixing, repression.Fe-05 powder agglomates cost of manufacture is low, and process for making is easy, and is easy to use and have a high-wearing feature.With arc-welding or plasma welding heat source, be with or without under the protection against oxidation condition, all can be the Fe-05 powder block surfacing on the surface of the work of steel.
Description
The present invention relates to a kind of hardfacing materials and preparation method thereof.
1962, US 3042790 disclosed a kind of stamped metal piece that can built-up welding De And can make various shape.The Main Ingredients and Appearance of this metal derby is iron, chromium, nickel, silicon, manganese, molybdenum, carbon etc., and its raw material is low-carbon ferrochromium, iron powder (low-carbon (LC)), nickel powder, ferro-molybdenum powder etc.This metal derby is cooperated by weight by the metal dust of above-mentioned raw materials, adds a certain proportion of waterglass mixing, mold pressing and drying and forms.
On the 2nd phase of nineteen eighty-three " welding " magazine, the chemical analysis that discloses a kind of high chromium boracic resurfacing welding material is: C:5～6.5%; Cr:48～52%; B:3～4%; Si:3～4%; Ni:2～3%; All the other all are weight percentage for Fe().
Can the simplified manufacturing technique process for producing, reduce the material manufacturing cost, easy to use, the hardfacing materials that has again high-wearing feature and high economic benefit, the present invention is on the basis of known technology, and having proposed a kind of code name is the formula for raw stock ratio of the wear-resisting refractory metal powder agglomates of Fe-05.
The raw material of surfacing welding alloy powder agglomates of the present invention is Mechanical Crushing powder and the 102Fe atomized powder of high carbon ferro-chrome, ferro-boron, ferrosilicon, and their weight ratio is high carbon ferro-chrome 60～80%; Ferro-boron 15～35%; Ferrosilicon 2%; 102Fe atomized powder 3%.It belongs to the chromium-base alloy system.The preparation method of Fe-05 powder agglomates is that raw material are broken into powder with machining process, and granularity is 50～300 orders, prepares in proportion even mixing, adds the waterglass bonding agent that accounts for powder weight 5～15%, forms loose granular alloy.Then should granular alloy in accordance with regulations weight be filled in the mould, impose every square centimeter of pressure more than 500 kilograms, 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 built-up welding thickness, can make the 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 at workpiece coating and dry process the characteristics such as the lost phenomenon of alloy-free.Metallographic structure after the built-up welding is still and contains the once eutectic structure of carbon chromium compound when dilution rate reaches 60%, and effective wear-resisting thickness is bigger.The Fe-O5 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.Adopt in addition plasma arc or tungsten argon arc thermal source can also realize the automation built-up welding.
