The utility model discloses a manufacturing method is simple, and the compound welt that makes has dual wear resistance, uses material cost low, and quick detachable and change new system ceramal prefab and weld, and it can not a prosthetic difficult problem to have solved compound welt, also reduces welt purchasing cost simultaneously.
Description
Technical field
The utility model relates to a kind of low cost, high abrasion ceramal composite liner, is applicable to the various liner plates of industry such as thermal power generation, cement, metallurgy, mine.
Background technology
In industries such as electric power, cement, metallurgy, mines, pulverized coal preparation system uses a large amount of lining board for grinding discs, and it is as main wearing piece, and its anti-wear performance directly has influence on the operating rate of powder process, quality of pc, material consumption and production cost.Due to any lining material, under powder process working condition, have comparatively serious wearing and tearing, after more serious pit, groove appear in wearing and tearing, coal pulverizer abrasive dust efficiency declines, and pulverizer capacity is not enough.Current thermal power plant lining board for grinding discs major part used is cast-in-block rich chromium cast iron, after service wear, build-up wear-resistant alloy material can improve the service life of grinding roller repeatedly in the above, but overlay cladding run into ature of coal poor time wear process in easily occur coming off.Adopt ceramic rod to inlay high chromium cast iron material and prepare ceramic composite lining board, the wearing and tearing initial stage can play certain wear-resisting effect, but the wearing and tearing later stage is preferentially ground with due to metal material, and ceramic rod is isolated to be protruded at backing surface, being squeezed, shearing force time easily rupture, do not have abrasion resistant effect.The ceramic particle composite strengthening liner plate that Magotteaux company of Belgium produces can play good abrasion resistant effect, but material monolithic adopts rich chromium cast iron, and cost is higher, and comparatively large for larger-size liner plate Post isothermal treatment difficulty, quality is unstable.
Utility model content
