Description
Technical field
The present invention relates to abrasion-proof backing block technical fields, and in particular to a kind of low chromium wear-resistant liner of low-carbon.
Background technology
Wear-resistant liner refers to that wear-resisting steel plate is process respectively by production technologies such as cutting, roll bending deformation, punching and welding
Kind wear-resistant liner, such as conveyer liner plate, feeder bottom plate/cyclone separator back taper and liner plate, abrasion-resistant blade, friction durability
15 times or more are improved than general steel plate.China will consume about 200,000 tons of lining board of grinder every year, about 200,000 tons of lining board of crusher,
Nearly 2,000,000,000 yuan are worth, therefore the loss for reducing lining material has highly important economic implications.The life of domestic and international lining material
The development that production and application have passed through more than 30 years, successively experienced potassium steel, ordinary white cast iron, ni-hard cast iron, rich chromium cast iron and arrives
The developing stage of several materials such as Hadfield steel and the various middle-low alloy steels smelted by Q-tempering technique.Institute
It states in several materials, the wearability of rich chromium cast iron is good but poor toughness.The toughness of Hadfield steel is high, and original hardness is low, makes
Its hardness is improved with austenite processing hardening is relied primarily in the process, can be obtained under the conditions of high impact loads well
Using effect, but used under the conditions of medium and small shock loading, austenite cannot be sufficiently hardened, and be worn no resistance.
In Chinese Patent Application No.：A kind of wear-resistant liner with long service life is disclosed in 201310727204, belongs to resistance to
Mill lining plate technique field.Mounting hole is offered on the wear-resistant liner of the present invention, wear-resistant liner is by following component and its quality percentage
