Abstract
The invention relates to a wear-resistant jaw plate for a jaw crusher and a preparation method thereof, belonging to the technical field of metal smelting. A working flank of the jaw plate provided by the invention is made of high-chromium cast iron, and a support back side of the jaw plate is made of medium carbon steel, so that a bimetal compound wear-resistant jaw plate is prepared. By three-box casting of sand molding, metal molding and sand molding, the service life of the working flank is prolonged.
Description
Technical field:
The present invention relates to a kind of jaw crusher wear-resistant jaw plate and preparation method thereof, belong to metal smelt technical field.
Technical background:
Jaw crusher is widely used in building materials, mine, metallurgical, the industry such as electric power and chemical industry, its operation principle mainly by moving jaw plate periodically near or leave fixed tooth plate, the material entered in crusher chamber is squeezed, splitting and bending, material, under shear stress effect, is fractureed along pressing from both sides cleavage surface altogether by rolling.Thus, require that jaw meets existing higher initial hardness, to resist raw material to its press-in, shear action, also should have enough toughness, slow down formation and the expansion of crackle.At present, mostly adopt potassium steel to make jaw both at home and abroad, because its initial hardness is lower, easily make jaw premature abrasion lose efficacy, belong to the low output of high abrasion, perplex the economic benefit of enterprise and the lifting of production efficiency always.
Summary of the invention
The object of the present invention is to provide and a kind ofly can improve the jaw crusher wear-resistant jaw plate in product service life and preparation method thereof.
Technical solution:
Jaw crusher wear-resistant jaw plate, the working flank material of described jaw adopts Gao Chrome cast iron, and jaw supports backing material and adopts medium carbon steel to make bimetal composite wear resistant jaw.
Further: high Chrome cast iron comprises row material, by mass percentage: C:2.40% ~ 3.10%, Si:0.50% ~ 1.0%, Mn:3.0% ~ 4.0%, Cr:17% ~ 19%, V:0.10% ~ 0.20%, Cu:1.0% ~ 1.05%, RE:0.04% ~ 0.10%, Mo:1.0% ~ 2.0%, P :≤0.10%, S :≤0.06%, Yu Weitie; Wherein RE is No. 1 rare earth ferrosilicon;
Medium carbon steel comprises row material, by mass percentage: C:0.30% ~ 0.50%, Si:0.30% ~ 0.65%, Mn:0.50% ~ 0.80%, P :≤0.04%, S :≤0.04%, Yu Weitie.
Further: the working flank thickness 40-60mm of jaw, jaw supports back side thickness 30-40mm.
Jaw crusher wear-resistant jaw plate preparation method, bimetal composite wear resistant jaw adopts liquid-liquid bimetallic compound, that is: first Gao Chrome cast iron and medium carbon steel are positioned in two intermediate frequency furnaces respectively, usual manner is adopted to be smelted into liquid, in the mould first medium carbon steel liquid castable extremely formed by the first sand mold+metal mold, after casting solidification, remove metal type dies, after second sand mold is combined to the first sand mold, then high Chrome cast iron liquid is poured in the model be made up of the first sand mold and the second sand mold, after Gao Chrome iron metal liquid solidifies, the demoulding, cleaning, polishing casting fin running gate system, in, outer quality after the assay was approved, to have carried out after heat treatment product.
After described medium carbon steel cast after 5s-50s, remove metal type dies.
After described medium carbon steel cast after 8s-35s, remove metal type dies.
After described medium carbon steel cast after 10s-30s, remove metal type dies.
After described medium carbon steel cast after 12s-25s, remove metal type dies.
After described medium carbon steel cast after 15s-20s, remove metal type dies.
Bimetal composite wear resistant jaw made by You Gao Chrome cast iron of the present invention and medium carbon steel, and the flank of tooth material of jaw adopts Gao Chrome cast iron, by sand mold+metal mold+sand mold three casees casting; Extend the service life of working face.
Contrast experiment is as follows:
Gao Chrome cast iron HDS:229-250, adopt single Gao Chrome cast iron materials to make Hubei Province plate, broken gangue, service life is at 5000-6000T, and bimetal composite wear resistant jaw working face HRC58-62 made by You Gao Chrome cast iron and medium carbon steel, broken gangue, service life is 20000-25000T, the latter improves 4-5 doubly than the former, and user is very satisfied, and cost performance has market prospects.
