The utility model provides a kind of blooming mill XA roller pass structure, its objective is reduction production cost.

To achieve these goals, the technical scheme that the utility model is taked is:

Blooming mill XA roller pass structure of the present utility model, the corresponding grooved of two XA rollers up and down of described blooming mill, constitutes overall pass, for the split rolling method of steel billet; The distance of described two XA rollers is up and down 20mm; Described pass comprises: A type, Type B, C type, D type and E type; Form the grooved of above-mentioned pass, its groove width × groove depth is respectively: 175 × 55mm, 210 × 65mm, 260 × 75mm, 345 × 75mm, 385 × 75mm;

The quantity of described A type is one, and the quantity of C type is two.

Particularly:

By the axis being parallel to described XA roller and towards on the direction of driving end, described pass distribution sequence and quantity are respectively:

One, A type; Type B one; One, C type; Type B one; One, C type; One, D type; One, E type.

The utility model adopts technique scheme to carry out pass reformation, and production actual production reaches and increases considerably than prior art, reduces the roll loss per ton steel of rolling process, reduces production cost.

Accompanying drawing explanation

Fig. 1 is the structural representation of prior art;

Fig. 2 is structural representation of the present utility model.

Detailed description of the invention

Contrast accompanying drawing below, by the description to embodiment, detailed description of the invention of the present utility model is described in further detail, have more complete, accurate and deep understanding to help those skilled in the art to inventive concept of the present utility model, technical scheme.

Structure of the present utility model as shown in Figure 2, be a kind of blooming mill XA roller pass structure, the claimed technical scheme of the utility model is applicable to the pass Curve guide impeller of rollcogging-roll in iron and steel enterprise's Rolling production.

The corresponding grooved of two XA rollers up and down of described blooming mill, constitutes overall pass, for the split rolling method of steel billet; The distance of described two XA rollers is up and down 20mm; Described pass comprises: A type, Type B, C type, D type and E type; Form the grooved of above-mentioned pass, its groove width × groove depth is respectively: 175 × 55mm, 210 × 65mm, 260 × 75mm, 345 × 75mm, 385 × 75mm.

Shown in Fig. 2, A type, Type B, C type, D type and E type are in figure respectively: BX3004, BX3003, BX3002, BX3001, BX3501.

In order to solve prior art Problems existing and overcome its defect, realize the goal of the invention reducing production cost, the technical scheme that the utility model is taked is:

As shown in Figure 2, blooming mill XA roller pass structure of the present utility model, wherein, the quantity of described A type is one, and the quantity of C type is two.

By rolling the quantity of type and redistributing of position to BX3002, BX3003, BX3004, reach the roll loss per ton steel reducing rolling process, reduce the object of production cost.

Particularly:

By the axis being parallel to described XA roller and towards on the direction of driving end, described pass distribution sequence and quantity are respectively:

One, A type; Type B one; One, C type; Type B one; One, C type; One, D type; One, E type.

Below technical solutions of the utility model are made a concrete analysis of:

1, cogging production technology characteristic is rolled according to two, box roller BX3002 groove utilization rate is the highest, Φ 105 ~ Φ 120 specification (corresponding BX3004) rolling 4 times, Φ 130 ~ Φ 150 specification (corresponding BX3003) rolling 4 times, Φ 160 ~ Φ 180 specification (corresponding BX3002), Φ 200 ~ Φ 210 specification (corresponding BX3001) rolling 3 times, Φ 190 specification (corresponding BX3501) rolling 5 times, according to roll pass sequence feature, be increased to two by an original BX3002 groove;

2, reduce to one by original two BX3004 grooves, that is: retain a BX3004 groove, even if when producing Φ 105 ~ Φ, 120 specification, this cover roller still can use, and ensures that Φ 105 ~ Φ 210 specification all can the omnipotent roller of rolling;

3, original BX3003 groove is changed greatly, become BX3002 groove; Original BX3004 groove is changed greatly, becomes BX3003 groove.

After carrying out pass reformation in a manner described, production actual production reaches than for increasing considerably before transformation, reduces the roll loss per ton steel of rolling process, reduces production cost.

By reference to the accompanying drawings the utility model is exemplarily described above; obvious the utility model specific implementation is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present utility model is conceived and technical scheme is carried out; or design of the present utility model and technical scheme directly applied to other occasion, all within protection domain of the present utility model without to improve.
