Abstract
Colliery D level round-link chain special-purpose steel.
The invention provides a kind of D level ring chain steel, it consists of: weight percent (%)
C Si Mn Ni 0.21～0.27 0.65～0.95 1.10～1.40 0.80～1.10
Mo AI S·P Cr Cu 0.10～0.20 0.02～0.05≤0.035≤0.35≤0.25
This D level ring chain steel mechanical property, processing performance tool are good, and the rich element that produces of China is based in the use of alloy element, because the C level chain of D level chain low one-level of generation uses, supporting capacity and transportcapacity all can improve 40%, steel consumption but saves 40%, prolongs 36～40% work-ing life.
Description
The invention belongs to D Mining level garden loop chain special-purpose steel.
Known mining garden loop chain uses its intensity of steel all at 150kg/mm
2Below, for example, the 20MnVK of present domestic use, the West Germany grade of steel 23MnCrNiMo52 and the 23MnCrNiMo34 of introduction, and the 806M22 of Britain's use, the SAE8620 that the U.S. uses, SAE4620, the 23MnCrNiMo64 that West Germany uses.By the coal in China Department of Industry mining high strength garden loop chain standard (MT36-80) regulation, D level chain will be at 150kg/mm with the intensity of steel
2More than, and good plasticity and toughness should be arranged, and the above-mentioned grade of steel of now using both at home and abroad, its intensity is all at 90～110kg/mm
2Between, can not be used as D level garden loop chain.
The purpose of this invention is to provide a kind of siliceous D level garden loop chain steel.
The invention is characterized in that it consists of: weight percent (%)
C Si Mn Ni Mo Al S·P Cr Cu
0.21 0.65 1.10 0.80 0.10 0.02
/ / / / / / ≤0.035 ≤0.35 ≤0.25
0.27 0.95 1.40 1.10 0.20 0.05
Steel grade provided by the present invention because the use of element silicon, and is controlled at tempering temperature about 350 ℃, has guaranteed the tough plasticity of this steel grade.Its intensity is greater than 150kg/mm
2Reach the steel requirement of D level chain, its cold roll forming, flash welding, thermal treatment adaptability all can fully satisfy the processing requirement of manufacturing garden loop chain, and the rich element that produces of China is based in the use of alloy element.Colliery D level circular chain steel is made in steel grade special use provided by the present invention, owing to there has been this steel grade that the production of stable D level colliery with the garden loop chain has just been arranged, c level chain with D level chain low one-level of generation uses, supporting capacity and transportcapacity all can improve 40%, and steel consumption saves 40%, prolongs 36～40% work-ing life.
