Description
Technical Field
The utility model relates to a grinding roller especially relates to a ceramic metal composite grinding roller.
Background
The rapid development of modern industry makes equipment have higher requirements on the wear resistance of parts, such as grinding rollers, millstones, crusher plate hammers and the like of vertical mills used in cement, mine, metallurgy, power stations or various similar industries, the hardness and toughness of traditional steel materials are usually contradictory, and in addition, the production working condition environment is complicated and severe, the grinding rollers have higher extrusion force and shearing force when working, the service life of the grinding rollers is still short, the grinding rollers need to be frequently replaced, the cost is high, the grinding rollers in the existing wear-resistant high-chromium cast iron process bring inconvenience to production, and the production efficiency is greatly reduced.
SUMMERY OF THE UTILITY MODEL
The utility model discloses just not enough to prior art exists provides a ceramic metal composite grinding roller.
In order to solve the above problems, the utility model adopts the following technical proposal:
the utility model provides a ceramic metal composite grinding roller, includes roll body and ceramic prefabricated section, the roll body is the cylinder form, and the outer wall of roll body has the slot along axial align to grid, and the slot is the fan-shaped column cell body of arc, and the ceramic prefabricated section is the fan-shaped column of arc, and the cross-section of ceramic prefabricated section is the echelonment, and ceramic prefabricated section lower part is the main aspects, and the main aspects of ceramic prefabricated section and the slot interference fit of roll body, and the roll body surface is exposed on the upper portion of ceramic prefabricated section, the surface of roll body has plated the one deck nickel layer.
Furthermore, the arc center of the slot and the ceramic precast block coincides with the axis of the roller body.
Further, the roller body is made of one of high manganese steel, alloy steel, high chromium cast iron, low nickel-chromium alloy cast iron and grey cast iron.
Compared with the prior art, the utility model discloses an implement the effect as follows:
a ceramic metal composite grinding roller, plate one deck nickel layer through the surface at the roll body, effectively improved the wear resistance of roll body, prolonged the life of grinding roller.
Drawings
Fig. 1 is a schematic structural view of a ceramic-metal composite grinding roller according to the present invention;
fig. 2 is a schematic structural diagram of the appearance of the ceramic precast block structure.
Detailed Description
The present invention will be described with reference to specific embodiments.
A ceramic-metal composite grinding roller as shown in fig. 1 and 2 comprises a roller body 10 and a ceramic precast block 11, the roller body 10 is cylindrical, the slots 12 are uniformly arranged on the outer wall of the roller body 10 along the axial direction, the slots 12 are arc-sector-shaped cylindrical groove bodies, the ceramic precast block 11 is arc-sector-shaped column bars, the section of the ceramic precast block 11 is in a step shape, the lower part of the ceramic precast block 11 is a big end, the big end of the ceramic precast block 11 is in interference fit with the slot 12 of the roller body 10, the upper part of the ceramic precast block 11 is exposed out of the surface of the roller body 10, because the ceramic precast block 11 has good wear resistance and impact resistance, after the ceramic precast block is uniformly distributed and arranged in the slots 12 on the surface of the roller body 10, the wear resistance of the grinding roller is improved, the service life of the grinding roller is prolonged, the outer surface of the roller body 10 is plated with a nickel layer, so that the wear resistance of the roller body 10 is improved, and the service life of the grinding roller is prolonged.
The arc center of the slot 12 and the ceramic prefabricated block 11 coincides with the axis of the roller body 10, so that after the ceramic prefabricated block 11 is installed in the slot 12, the whole stress of the grinding roller is uniform, the deformation of the grinding roller due to stress is not easy to occur, and the normal use of the grinding roller is ensured.
One of the high manganese steel, the alloy steel, the high chromium cast iron, the low nickel-chromium alloy cast iron and the grey cast iron of the roller body provides multiple possibilities for selection of the roller body, further reasonably optimizes the manufacturing cost, ensures the wear resistance of the roller body and prolongs the service life of the grinding roller.
To sum up, a ceramic metal composite grinding roller have following effect:
a ceramic-metal composite grinding roller, install fan-shaped cylindrical ceramic prefabricated section 11 interference fit in slot 12 of roll body 10, ceramic prefabricated section 11 evenly axial distributes, forms ceramic-metal composite grinding roller, and the installation is dismantled and is maintained conveniently, has reduced manufacturing cost, has improved the wear resistance of grinding roller, has prolonged life.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
