Abstract
The utility model relates to a lining board, in particular to a bimetal composite casting chilling wear-resistant lining board, which has the difference that: the lining board consists of a wear-resistant layer and a toughness layer, the thickness of the wear-resistant layer is one second to three fifth of the total thickness of the lining board, and the thickness of the toughness layer is two fifth to one second of the total thickness of the lining board, compared with the raw material high manganese steel (Mn13) lining board serving in the same operating condition, the lining board has advantages of extending the service life by three to five times, saving resources and materials for the country, simple production process and high performance/cost ratio, and is the ideal standby product for saving energy, reducing discharge and consumption and increasing yield for enterprises.
Description
Technical field
The utility model relates to a kind of liner plate, particularly relates to the chill abrasion-proof backing block of a kind of bimetal composite casting.
Background technology
In the world, China is castings production big country, and the foundry goods total amount ranks the first.In industries such as metallurgy, electric power, building materials, cement, mine, most producers do not have science material, selection, no matter any working condition relates to high-abrasive material with regard to first-selected potassium steel (Mn13), because potassium steel is brought into play its anti-wear performance of not coming out in the process of abrasive wear, cause the too early inefficacy of material, and cause waste to national resources.
Ball mill is a kind of milling apparatus, and its operation principle is to install liner plate on cylindrical shell, and material and the operation of abrading-ball combining of high speed are with material porphyrize powder.Because liner plate bears abrading-ball bump and the wearing and tearing of hard material under arms in the process, so wear liner performance high tenacity is when hanging down, liner plate easy fracture and fragmentation; When liner plate toughness high-wearing feature was hanged down, liner plate also can premature failure.
Summary of the invention
Problem to be solved in the utility model is to propose the chill abrasion-proof backing block of a kind of bimetal composite casting at above-mentioned prior art, and its manufacturing process is simple, and wearability and toughness all are improved, and have formed best coupling.
The utility model is adopted solution to be by the problem of the above-mentioned proposition of solution: the chill abrasion-proof backing block of bimetal composite casting, its difference is to be made up of wearing layer and ductile layers, the thickness of wearing layer is 1/2～3/5 of liner plate gross thickness, and the thickness of ductile layers is 2/5～1/2 of liner plate gross thickness.
Wearing layer material of the present utility model raw material commonly used is the composite abrasion resistance material of compositions such as C, Si, Mn, Cr, W, M, and ductile layers is then for containing the compound toughness material of compositions such as C, Si, Mn.
The utility model bimetal composite casting is chill, and the abrasion-proof backing block Casting Technology is: above-mentioned composite abrasion resistance material and compound toughness material are adopted two stove meltings respectively, after treating fusion, pour into respectively and can guarantee also in the same casting mold that high-abrasive material molten iron partly is in the claimed range of regulation, its high-abrasive material position adopts Special Processes of Metal Castings technology to make the liner plate working face obtain chilling layer, dense structure, grain refinement has more effectively improved anti-wear performance.
The utility model is two kinds of steel grades and different mechanical properties after the cast form:
Liner plate working face (wearing layer) mechanical property: Rockwell Hardness HRC 55～62
Liner plate non-working surface (ductile layers) mechanical property: yield strength 6s 260～280Mpa
Composite bed: impact toughness a K 〉=20J/cm
2
The beneficial effects of the utility model are:
The utility model is on active service under equal working condition with raw material potassium steel (Mn13) liner plate and is compared, improve 3～5 times of service lifes, for country saves resource material, production technology is simple, product price ratio height is that industry energy conservation reduces discharging, consumption is increased income optimal spare part product.
