Description
Technical field
This patent relates to a kind of novel wear resistant structure of high-pressure roller mill compression roller side built-up welding hard formation, belongs to Roller of High wear-proof technique field, especially the abrasion-proof structure of high-pressure roller mill compression roller side built-up welding hard formation.
Background technology
At present, the compression roller of two opposite direction rotatings of high pressure roller mill, under hydraulic system effect, produces huge extruding force by crushing material.The compression roller Life Relation of high-pressure roller mill is to operation rate and maintenance cost.The roller side of tradition roll mill adopts overall structure, and wearing and tearing appear in side in use for some time, cause compression roller and side shield and lower side panel excesssive gap, thereby makes side leak material, and the local material of side is pressed the phenomenons such as inadequate.This kind of structure is unfavorable for the sustainable use of roller shell, once may wear to a certain degree, even whole roller shell will be scrapped, and increased the duration and cost of maintenance of equipment.
Utility model content
The problem existing for solving prior art, the purpose of this utility model is to design a kind of novel wear resistant structure of high-pressure roller mill compression roller side built-up welding hard formation.It is high that this structure has hardness, and wearability is good, and the features such as long service life can reduce maintenance of equipment expense, reduces the maintenance of equipment time, effectively improves operation rate.Simultaneously can also indirect protection side shield and lower side panel, slow down its rate of wear, limited extension device service life.
For realizing object as mentioned above, the utility model adopts technical scheme as described below:
A novel wear resistant structure for high-pressure roller mill compression roller side built-up welding hard formation, is provided with the roller shell that is sleeved on compression roller outside, and a plurality of studs that roller shell is located at hot hard formation outer surface by hot hard formation and nail form.
Two lateral edges of roller shell described in the utility model are respectively equipped with an annular groove, are welded with ring-like built-up welding hard formation in annular groove.
The end face of built-up welding hard formation described in the utility model is higher than the end face of roller shell.
Built-up welding hard formation described in the utility model is comprised of a plurality of ring-like hard formations
.
Owing to adopting technical scheme as above, the present invention has superiority as described below:
A novel wear resistant structure for high-pressure roller mill compression roller side built-up welding hard formation, is applicable to the industrial circle brittle mineral grinding operations such as metallurgy, mine, coal, chemical industry.The abrasion-proof structure of its compression roller side built-up welding hard formation is comprised of roller shell, built-up welding hard formation, and roller side of the present utility model has the features such as hardness is high, erosion resistance strong, long service life.
The novel wear resistant structure of high-pressure roller mill compression roller side built-up welding hard formation, has increased the wearability of roll surface side, effectively prevents that side from leaking material, and Granularity Distribution is produced to active influence, has improved the mill efficiency of roll mill.Simultaneously, the method that the resurfacing welding material that the abrasion-proof structure of this high-pressure roller mill compression roller side built-up welding hard formation adopts carries out built-up welding hard formation is than existing roll surface side structure, roll surface hard formation erosion resistance is good, even can carry out repeated overlaying weldability roller side hard formation to it after wearing and tearing, roller shell can continue to use, also make the replacement cycle of roller shell greatly extend, and extended service life, because the built-up welding of roller side is convenient, reduced roller maintenance cost, reduce maintenance time and maintenance cost, effectively improved operation rate.

In figure: 1, compression roller, 2, hot hard formation, 3, stud, 4, side transition zone, 5, side hard formation, 6, roll surface transition zone, 7, roll surface hard formation I, 8, roll surface hard formation II, 9, roller shell, 10, annular groove, 11, built-up welding hard formation.
The specific embodiment
As shown in the figure, a kind of novel wear resistant structure of high-pressure roller mill compression roller side built-up welding hard formation, be provided with the roller shell 9 that is sleeved on compression roller 1 outside, roller shell 9 becomes an integral body with compression roller hot charging, and a plurality of studs 3 that roller shell 9 is located at hot hard formation 2 outer surfaces by hot hard formation 2 and nail form.
Two lateral edges of described roller shell 9 are respectively equipped with an annular groove 10, are welded with ring-like built-up welding hard formation 11 in annular groove 10, and described built-up welding hard formation is piled on roller side, reaches the effect of in use protecting roller side.
The end face of described built-up welding hard formation 11 is higher than the end face of roller shell 9, and minimizing abrasive material contacts with roller shell, protection roller shell avris.
Described built-up welding hard formation 11 is comprised of a plurality of ring-like hard formations.Comprise side filter course 4, side hard formation 5, roll surface filter course 6, roll surface hard formation I 7 and roll surface hard formation II 8, when one of them hard formation damages, can change separately.
The novel wear resistant structure of a kind of high-pressure roller mill compression roller side built-up welding hard formation that the utility model is related; roller shell adopts superior alloy steel; and through Overheating Treatment; make roller shell surface hard formation reach certain hardness; and hard formation reaches certain degree of depth; for hot hard formation; punching dress stud on roller shell; this stud roll surface is under high pressure during comminuting matter; have stronger erosion resistance, roller shell side is outputed two ring grooves, built-up welding welding material in this annular groove; form hard formation, in use protect roller side.
After described compression roller 1 becomes an integral body with roller shell 9 hot chargings, at roller shell side processing annular groove, as shown in Figure 2; Side filter course 4, side hard formation 5, roll surface filter course 6, roll surface hard formation I 7 and roll surface hard formation II 8 heaps are soldered in manufactured roll side side ring groove 10, heap is soldered heat-treats compression roller, remove the stress producing in weld deposit process, then in roller shell Surface Machining stud hole, stud is installed.The welding material that the abrasion-proof structure of described compression roller side built-up welding hard formation adopts, heap postwelding hard formation hardness, higher than 55HRC, adopts this kind of resurfacing welding material, has hardness high, the feature that erosion resistance is strong.
High pressure roller mill is when comminuting matter; owing to having certain gap between roller side and side shield and lower side panel; in use; more tiny material enters wherein; thereby wearing and tearing are very fast; by the compression roller side abrasion-proof structure of inlaying the roller shell 9 of stud 3 and the hard formation of roller side built-up welding and forming, will effectively protect roller shell side, slow down wearing and tearing.In addition, because the built-up welding hard formation of roller shell side is easy to maintenance, built-up welding repeatedly, has effectively extended roller shell service life, thereby improves the service life of compression roller and complete machine.
