Abstract

The utility model discloses a roll of a conveying roller table of a rolled steel inlet/outlet furnace, which belongs to the field of rolled steel conveying devices. The technical scheme is as follows: the table roll comprises a hollow roll body; two ends of the roll body are provided with roll-end plates; spigots are arranged at the coordination parts of the inner wall of the roll body and the roll-end plates; roll shafts are fixedly connected at the center of the outer end surface of the roll-end plates axially; and ledges are arranged at the connection parts of the roll shafts and the roll-end plates. The roll of the conveying roller table of the rolled steel inlet/outlet furnace has simple structure, low investment cost, and breaks the traditional using method of an integral cast part; all parts are assembled and combined, the spigots are arranged at the coordination parts of the roll body and the roll-end plates, and the ledges are arranged at the connection parts of the roll shafts and the roll-end plates, therefore, the structure of the roll is more firm and reliable, thus reducing the wear degree of the roll body, overcoming the phenomenon of easy crack of the roll shafts, improving the durability of the roll, solving the problem of frequent replacement, and reducing the operating cost of the roll simultaneously.

Description

A kind of steel rolling goes out, goes into stove transmission roller channel roller

Technical field

The utility model relates to a kind of steel rolling and use the transmitting device field, refer in particular to the roller that a kind of steel rolling mill goes out, goes into stove district transmission roller channel.

Background technology

At present, the existing roller that goes out, goes into stove district transmission roller channel of steel rolling mill's workshop, great majority are that to adopt the body of roll and roll shaft be the cast member of one, in process of production, on the one hand the roller load that is in operation is heavier, moreover starts too continually, cause body of roll wearing and tearing very fast, consumption is big; On the other hand, the roller of this casting exists defective because material is more crisp on the manufacturing process, cause the wearing and tearing of stove district transmission roller channel comparatively seriously, roll shaft is ruptured easily, cause all needing in every month more to renew roller, like this, improved the operation cost of device greatly.This is the existing in prior technology weak point.Therefore, needing to adjust the structure of roller, improve the quality of roller, improve the abrasion resistance of roller surfaces, reduce the operation cost of roller-way device, is the key of head it off.

The utility model content

The purpose of this utility model, be exactly at the existing in prior technology deficiency, and a kind of improved technical scheme is provided, in this scheme, described body of roll inwall and roll end plate cooperation place are provided with seam, make roller structurally more solid and reliable, and the junction of described roll shaft and roll end plate is provided with shoulder, overcome the phenomenon of roll shaft easy fracture, the wearing and tearing of the body of roll have been reduced, avoided the problem of frequent roll change, greatly reduced in the transmission roller channel device, the cost of roller in operation.

The technical scheme that its technical problem that solves the utility model adopts is: a kind of steel rolling goes out, goes into stove transmission roller channel roller, described roller-way roller comprises the body of roll of hollow, the two ends of this body of roll are equipped with roll end plate, described body of roll inwall and roll end plate cooperation place are provided with seam, center, outer face in described roll end plate, be fixedly connected with roll shaft vertically, the junction of this roll shaft and roll end plate is provided with shoulder.

The concrete technical scheme that the utility model adopted also has: the above-mentioned body of roll is a seamless steel pipe, and above-mentioned roll shaft is a round steel.

The beneficial effects of the utility model are learnt by the such scheme narration: the utility model is simple in structure, cost of investment is cheap, broken the use of traditional integrally casting spare, by each assembling of assembly ground and combination, and be provided with seam at the body of roll and roll end plate cooperation place, the junction of roll shaft and roll end plate is provided with shoulder, make roller structurally more solid and reliable, thereby reduced the degree of body of roll wearing and tearing, overcome the phenomenon of roll shaft easy fracture, strengthen the durability of roller, solved the problem of frequent replacing, also reduced the operation cost of roller simultaneously.This shows that this programme compared with prior art has substantive distinguishing features and progress, the beneficial effect of its enforcement also is conspicuous.

Fig. 2 is the M partial enlarged view of Fig. 1.

Among the figure: 1, the body of roll, 2, roll shaft, 3, roll end plate, 4, shoulder, 5, seam.

The specific embodiment

For clearly demonstrating the technical characterstic of this programme,, this programme is set forth below by a specific embodiment.

As shown in Figure 1 and Figure 2, a kind of steel rolling goes out, goes into stove transmission roller channel roller, described roller-way roller comprises the body of roll 1 of hollow, the two ends of this body of roll 1 are equipped with roll end plate 3, the described body of roll 1 inwall and roll end plate 3 cooperation places are provided with seam 5, center, outer face in described roll end plate 3 is fixedly connected with roll shaft 2 vertically, and this roll shaft 2 is provided with shoulder 4 with the junction of roll end plate 3.

The described body of roll 1 is the seamless steel pipe of 20# steel, described roll shaft 2 is the round steel of 45# steel, described roll end plate 3 is the steel plate of Q235A material, the described body of roll 1 inwall and roll end plate 3 cooperation places are provided with seam 5, make roller structurally more solid and reliable, junction in described roll shaft 2 and roll end plate 3 is provided with shoulder 4, has overcome the phenomenon of roll shaft 2 easy fractures.

In addition, reach the hardening heat of production requirement for making roller surfaces, heat-treat on the pair of rollers surface, makes the body of roll 1 case hardness reach HRC=58-63, and the hardness of roll shaft 2 reaches HB217-235.

Claims
