Abstract
The utility model provides a kind of Compound Extrusion roller, comprises compression roller roller embryo, it is characterized in that roller embryo surface is provided with prime coat, transition zone, hardstanding and surge layer from inside to outside successively.The surface recombination Rotating fields formed by multiple layers of different materials, effectively improve the integral hardness of compression roller roll surface, make it that there is higher polishing machine, make this compression roller in use there will not be the problem of surface layer peeling, substantially increase the service life of compression roller.Additionally by the setting of prime coat, transition zone, hardstanding, surge layer, making press roll surface in weld deposit process without the need to carrying out preheating and after-baking, simplifying construction procedure, improve product quality.
Description
Technical field
The utility model relates to a kind of compression roller, particularly a kind of Compound Extrusion roller, belongs to Machine Design manufacturing technology field.
Background technology
In manufacture of cement industry, cement grinding system adopts roll squeezer as the pre-grinding of ball mill or half end milling equipment.Because roller press squeeze roll condition of work is severe, so roll surface wearing is comparatively serious.After generally running half a year continuously, the wear-resisting decorative pattern of roll surface just weares and teares totally, makes producer have to repair roll surface.Not only increase the production cost of cement producer like this, and adverse effect can be caused to product quality.According to comparatively wear-resisting integral cast alloy roller as compression roller, normally carrying out of production can be affected because repairing after damage.And the roller adopting submerged-arc welding to prepare product as an alternative, the roller can prepared because of submerged-arc welding again needs to carry out preheating and after-baking and makes troubles to site operation.Therefore be necessary to be improved prior art.
Summary of the invention
For solve roller machine roller that existing cement grinding system uses due to wearability poor, need to repair roll surface after using a period of time, cause cost increase and affect the problems such as product quality, the utility model provides a kind of Compound Extrusion roller.
The utility model is completed by following technical proposal: a kind of Compound Extrusion roller, comprise compression roller roller embryo, it is characterized in that roller embryo surface is provided with prime coat, transition zone, hardstanding and surge layer from inside to outside successively, to increase the wear resistance of compression roller by the four-layer structure of built-up welding.
Described prime coat is set to austenite stainless steel layer, and its thickness is 4 ~ 8mm.
Described transition zone is set to middle manganese stainless steel layer, and its thickness is 6 ~ 10mm.
Described hardstanding is set to high-chromium cast iron alloy layer, and its thickness is 8 ~ 12mm.
Described surge layer is set to high chromium height niobium cast-iron alloy layer, and it is the tongue and groove arranging one week vertical bar line along hardstanding surface, and the groove of tongue and groove is high is 4 ~ 6mm.
The utility model has following advantages and effect: adopt such scheme, the surface recombination Rotating fields formed by multiple layers of different materials, effectively improve the integral hardness of compression roller roll surface, make it that there is higher polishing machine, make this compression roller in use there will not be the problem of surface layer peeling, substantially increase the service life of compression roller.Additionally by the setting of prime coat, transition zone, hardstanding, surge layer, making press roll surface in weld deposit process without the need to carrying out preheating and after-baking, simplifying construction procedure, improve product quality.Be a desirable compression roller in fact.
