Description
Technical field
The present invention relates to a kind of welding material, and in particular to a kind of cermet grinding roller and preparation method thereof.
Background technology
Coal pulverizer is widely used in thermal power plant, mine, cement plant and prepares Pulverized Coal.Pulverized Coal doping hardness of matter
Cause Roller of Coal Grinder abrasion violent, cause service life short, comprehensive resources waste serious.Usual Roller of Coal Grinder is by Gao Ge
What cast iron and steel alloy were cast, if casting replacing again because of grinding roller wear out failure, greatly waste certainly will be caused, and
Greatly increase production cost.Abrasion is resisted using build-up wear-resistant coating technology for this many Roller of Coal Grinder, so as to extend
The service life of part, improves equipment operating efficiency, reduces integrated cost, category energy-saving and emission-reduction field.
The grinding roller of coal pulverizer uses build-up wear-resistant coating technology, is in mill roll sleeve surface shape by abrasion-resistant powder core welding wire built-up welding
Into wear-resistant coating.Built-up welding back roller set is compared with new product cast member, because wearing layer hardness is higher, the mill of built-up welding scuff-resistant coating more non-than it
Roller can more effectively resist abrasive wear, thus with the wearability more much better than than non-built-up welding grinding roller.
In the prior art, the char-forming material such as tungsten carbide, titanium carbide is as the hard phase in grinding roller, because its is hard and crisp, tough
Property it is poor, high stress, be hit, work under the working condition such as strong fatigue when, wearing layer is also easy to produce crackle, Particle Breakage and de-
Fall, so as to lose wearability.Secondly as mill roll sleeve mother metal is generally rich chromium cast iron, the bead welding wire of carburet gold into
Point difference is big, causes solder joints low intensity, and the matrix of wearing layer and grinding roller is easily peeled off, and loses wearability.
