Abstract
The utility model discloses a kind of heat-resistant antifriction charge roll mill table roller, it comprises roll shaft, roller shell, adpting flange and high-strength bolt, described roller shell is set on the axle body of roll shaft, roll shaft is also arranged with the adpting flange that two lay respectively at roller shell two ends, adpting flange and roller shell are fastenedly connected by high-strength bolt, and adpting flange is fastenedly connected by welding with roll shaft.
Description
Technical field
The utility model belongs to charge roll mill technical field, particularly relates to a kind of heat-resistant antifriction charge roll mill table roller.
Background technology
At present, on the steel rolling production-line of the various model of rolling, specification, the devices such as all kinds of rollgang, working roll are absolutely necessary one of visual plant, roller on existing each rollgang and the structure of working roll generally all adopt solid forging, casting adds the structure such as welding, alloy seamless welding, roller in the course of the work, because the body of roll on it is different with the operating mode at roll shaft position, therefore, also just different to its performance requirement; But the roller of existing structure is owing to being entirety or Welding Structure, the material capability at each position is all identical or close, this just can not meet the performance requirement at each position of need of production simultaneously, and this just causes, and the life-span of roller is shorter, replacing is frequent, makes production cost higher.
Summary of the invention
In order to solve problems of the prior art, the purpose of this utility model is to provide a kind of heat-resistant antifriction charge roll mill table roller.
In order to realize foregoing invention object, the utility model adopts technical scheme as described below:
A kind of heat-resistant antifriction charge roll mill table roller, it comprises roll shaft, roller shell, adpting flange and high-strength bolt, described roller shell is set on the axle body of roll shaft, roll shaft is also arranged with the adpting flange that two lay respectively at roller shell two ends, adpting flange and roller shell are fastenedly connected by high-strength bolt, and adpting flange is fastenedly connected by welding with roll shaft.
Further, described roll shaft adopts 40Cr material.
Further, described roller shell adopts KmTBCr20 material
.
Owing to adopting technique scheme, the utility model has following superiority:
The utility model adopts the roll shaft with the 40Cr steel matter of higher-strength and has the overall structure that KmTBCr20 material roller shell that is heat-resisting, anti-wear performance is preferably connected, the performance requirement of roller each working position in the course of the work all can be met, substantially prolongs working life, reduce production cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure: 1-roll shaft; 2-roller shell; 3-adpting flange; 4-high-strength bolt.
Detailed description of the invention
Below in conjunction with drawings and Examples, the technical solution of the utility model is described in further detail.
As shown in Figure 1, a kind of heat-resistant antifriction charge roll mill table roller, it comprises roll shaft 1, roller shell 2, adpting flange 3 and high-strength bolt 4, described roller shell 2 is set on the axle body of roll shaft 1, roll shaft 1 is also arranged with the adpting flange 3 that two lay respectively at roller shell 2 two ends, adpting flange 3 and roller shell 2 are fastenedly connected by high-strength bolt 4, and adpting flange 3 is fastenedly connected by welding with roll shaft 1.
In actual process, described roller shell 2 external diameter reserves certain allowance for finish, heats 120 DEG C-150 DEG C and is set on the axle body of roll shaft; On roll shaft 1, all cooperation positions reserve allowance for finish, sheathed two adpting flanges laying respectively at roller shell two ends, flange and axle body adopt key be connected and realized by welding fastening, adpting flange and roller shell are fastenedly connected by high-strength bolt, after fastening, bolt is welded with adpting flange, after whole assembling process completes, carry out fine finishining.
Roll shaft in the utility model adopts the 40Cr material steel with higher-strength and toughness, roller shell adopts the material with better heat-resistant antifriction performance, make roller in the course of the work roll shaft and the body of roll service behaviour require all can meet, compared to the roller of traditional structure, the working life of roller of the present utility model can improve 10-20 doubly, greatly reduces production cost.
