Description
Technical field
The present invention relates to a kind of bead welding wire, particularly a kind of flux-cored wire that is used for concrete pump S pipe valve, cheater plate and the wear ring of building trade.
Technical background
At present, the S pipe valve of the concrete pump that building trade is made, eye slab and wear ring are to adopt surfacing welding, because concrete is in continuous conveying process, above-mentioned parts form heavy wear and make the delivery pump cisco unity malfunction life-span short.The above-mentioned parts of concrete pump carry out the welding rod built-up welding, and not only requiring has enough hardness, intensity, shock-resistant, also wants anti-wear performance good.And do not have the bead welding wire of special-purpose concrete pump in the prior art; Though and general surfacing welding hardness height wears no resistance, service life is short.So existing surfacing welding can not satisfy delivery pump S pipe valve, eye slab and the wear ring specification requirement of building manufacturing.
Summary of the invention
The objective of the invention is to overcome above-mentioned shortcoming and defect, a kind of flux-cored wire that is specifically designed to concrete pump S pipe valve, cheater plate and wear ring is provided, thereby improves greatly wearability and service life.
The objective of the invention is to realize by following technical proposal: a kind of flux-cored wire that is used for concrete pump S pipe valve, cheater plate and wear ring is characterized in that the chemical analysis of this flux-cored wire with weight % is:
Carbon 3.0～4.0 vanadium 2.5～3.5 chromium 28～34 niobiums 2.5～3.5
Manganese 1.0～3.0 boron 0.5～1.5 silicon 0.5～2.0 rare earth 2.5～3.0
Tungsten 6.0～8.0 molybdenums 2.5～3.5 surpluses are iron,
Crust adopts mild-carbon steel strip, and core is filled the mentioned component alloy powder, gets final product through being drawn into silk.
This flux-cored wire crust adopts the low-carbon (LC) mild-carbon steel strip, alloy powders such as the high carbon ferro-chrome by adding proper proportion, vanadium iron, molybdenum-iron, niobium powder, manganese metal, ferro-boron, ferrosilicon, rare earth, make flux-cored wire, make this flux-cored wire chemical analysis be with weight %
Carbon 3.0～4.0 vanadium 2.5～3.5 chromium 28～34 niobiums 2.5～3.5
Manganese 1.0～3.0 boron 0.5～1.5 silicon 0.5～2.0 rare earth 2.5～3.0
Tungsten 6.0～8.0 molybdenums 2.5～3.5 surpluses are iron.This welding wire crust adopts steel band, and core is filled the mentioned component alloy powder, gets final product through being drawn into silk.
This flux-cored wire is pressed certain ball milling powdered by following step production: A, batching with each raw material.The oven dry, again each raw material is mixed by a certain percentage can, the hopper of packing into.B, sanction band: will be with steel to be cut into 0.25 * 14mm or 0.25 * 16mm steel band, and be rolled into concave groove by roll then, medicinal powder is added concave groove according to the filling ratio.C, the concave groove sealing that will add medicinal powder.D, to be rolled into diameter be Φ 0.4mm welding wire, is drawn into the welding wire of Φ 3.0mm at last.
This flux-cored wire has higher carbon content and multiple alloying element; The carbon martensite forming element also is the essential element that improves deposited metal hardness, adds elements such as chromium, vanadium, niobium, molybdenum and reacts, improved the structure and the distribution of carbide, refinement crystal grain, improve overlay cladding toughness, reach the cracking resistance height, thereby improve the overlay cladding anti-wear performance; When overlay cladding cools off, can obtain high strength, high rigidity, shock-resistant, high abrasion, the overlay cladding of good combination property.
Flux-cored wire according to above-mentioned chemical analysis making, the built-up welding performance is good, moulding is attractive in appearance, intensity height, hardness height, impact resistance is good, wearability is good, and its hardness can reach HRC 〉=65, long service life, this bead welding wire is a kind of building trade concrete pump S pipe valve, eye slab and wear ring manufacturing and repair desirable flux-cored wire.
