Abstract
The invention discloses a surfacing composite grinding roller applied to pulverized coal grinding equipment in the fields of electric power, metallurgy, coal, iron and steel and coal chemical industry. The surfacing composite grinding roller comprises a grinding roller sleeve, a shaft sleeve and a grinding shaft. The shaft sleeve is sheathed on the grinding shaft; the grinding roller sleeve is fixed on the shaft sleeve; and the outer surface of a base layer of the grinding roller is provided with a surfacing layer. The base layer is prepared from material with high toughness and good thermal stability through one-step casting forming; the surfacing layer made of high wear-resistant and heat-resistant material is deposited on the base layer, so as to solve a series of problems of an existing grinding roller sleeve. The surfacing composite grinding roller has the advantages of long service life, safety, reliability and low manufacturing cost; and at the same time, the surfacing layer can be reused in surfacing compound, so as to meet the requirements of the development of circular economy.
Description
Technical field
The present invention relates to a kind of milling apparatus that grinds use for coal dusts such as electric power, metallurgy, coal, iron and steel, Coal Chemical Industries, especially relate to the mixing roll on milling apparatus.
Background technology
In industries such as electric power, metallurgy, coal, iron and steel, Coal Chemical Industries, all need to use coal, but these coals must grind to form the coal dust of certain granules size before use could be used, these producers all adopt milling apparatus to grind coal for this reason.In milling apparatus, mixing roll is material to be rolled to the critical piece of pulverizing, it forms by grinding roller shell, axle sleeve and grinding shaft etc., and grind roller shell as the critical component of bringing into play abrasive action, not only affect the height of output its service life, the safe operation of grinding simultaneously roller shell is determining the realization of enterprise's productivity effect especially.In process of lapping, be subject to the relative extruding of mixing roll and mill and be ground into fine particle with the various materials between mixing roll between mill.Grind in the process of roller shell conducting powder mill operation, not only need to overcome formation abrasion, cutting abrasion, cutter skiving and undermine fatigue wear, simultaneously in the drying course due to grinding material, also need to bear-variations in temperature of 20-400 ℃, so high abrasion, high-fire resistance are the operations of mixing roll long-term safety, reduce the deciding factor of spare parts cost.Owing to grinding roller shell, be easily-consumed products, domestic many producers are in order to improve its service life for this reason, the numerous and confused alloy material of high abrasion that adopts is made, so just increased substantially the production cost that grinds roller shell, after grinding simultaneously the roller shell wearing and tearing, can only melt down casting processing again, so greatly increase the production cost that uses producer, do not met " minimizing, recycling, recirculation, manufacture again " development principle of recycling economy.
Summary of the invention
The object of the invention is to provide a kind of composite build up welding grinding roller of new structure, grinding roller shell is that the overlay cladding on basal layer forms by the basal layer as aperture surface and built-up welding, basal layer is selected the mode one-shot forming of the material of high tenacity and Heat stability is good by casting, overlay cladding selects high abrasion and the built-up welding of high-fire resistance material on basal layer, thereby solved the existing existing series of problems of roller shell that grinds, have the advantages such as life cycle is long, safe and reliable, low cost of manufacture, after overlay cladding wearing and tearing simultaneously, built-up welding is compound again, meets the requirement of recycling economy development.
The technical scheme that realizes the object of the invention is:
A kind of composite build up welding grinding roller comprises and grinds roller shell, axle sleeve and grinding shaft that described axle sleeve is sleeved on described grinding shaft, and the described roller shell that grinds is fixed on described axle sleeve, it is characterized in that: at the described outer surface that grinds the basal layer of roller shell, one overlay cladding is arranged.
The described roller shell that grinds is by cone voussoir and some equally distributed being bolted on described axle sleeve.
The present invention compared with prior art has following advantage:
1. change original manufacture of grinding the roller shell integrally casting, adopt the method for cast welding combination, basal layer is selected the mode one-shot forming of the material of high tenacity and Heat stability is good by casting, overlay cladding selects high abrasion and the built-up welding of high-fire resistance material on basal layer, increases substantially the service life of grinding roller shell.
2. after the overlay cladding wearing and tearing, built-up welding is compound again, has reduced the production cost that uses producer, meets the requirement of recycling economy development.
3. adopt the basal layer of straight carbon steel or low-alloy steel material, can account for and grind more than 80% of roller shell weight, the overlay cladding that the special substance cost is high only accounts for 20% weight, with original roller shell that grinds, all adopt the manufacture of high alloy material to compare, decrease the consumption of expensive material, realize the remarkable decline of manufacturing cost.
4. grind roller shell by cone voussoir and some equally distributed being bolted on described axle sleeve, the installation of conveniently grinding roller shell on the one hand, guarantee the concentricity of grinding roller shell and grinding shaft by the cone voussoir on the other hand.
The accompanying drawing explanation
Fig. 1 is the structural representation of composite build up welding grinding roller of the present invention.
In figure: 1. grind roller shell, 2. overlay cladding, 3. basal layer, 4. cone voussoir, 5. bolt, 6. axle sleeve, 7. grinding shaft, 8. mill.
The specific embodiment
Following examples are for illustrating the present invention, but are not used for limiting the scope of the invention, and all technical schemes that are equal to also belong to category of the present invention, and scope of patent protection of the present invention should be limited by every claim.
As can be seen from Figure 1, a kind of composite build up welding grinding roller, comprise and grind roller shell 1, axle sleeve 6 and grinding shaft 7, described axle sleeve 6 is sleeved on described grinding shaft 7, the described roller shell 1 that grinds is fixed on described axle sleeve 6 by cone voussoir 4 and some equally distributed bolts 5, at the described outer surface that grinds the basal layer 3 of roller shell 1, one overlay cladding 2 is arranged.
In order to guarantee that mill 8 and the anti-wear performance that grinds roller shell 1 are consistent substantially, on mill 8 also built-up welding identical material is arranged overlay cladding 2 in process of lapping, the various materials between the overlay cladding 2 of mill 8 and grinding sleeve 1 are subject to the relative extruding of grinding sleeve 1 and mill 8 and are ground into fine particle.
Claims (2)
1. composite build up welding grinding roller, comprise grind roller shell (1), axle sleeve (6) with grinding shaft 7, (6) described axle sleeve is sleeved on described grinding shaft and (7) goes up, and (1) the described roller shell that grinds is fixed on described axle sleeve and (6) goes up, and it is characterized in that: one overlay cladding is arranged (2) at the described roller shell basal layer (1) outer surface (3) that grinds.
