CN205949499U - Broken phosphorus draws rectifys quick -witted backing roll range structure - Google Patents

Abstract

Broken phosphorus draws rectifys quick -witted backing roll range structure, a plurality of backing roll alternating expressions arrange in the roller box on the frame. The utility model discloses the backing roll hands over misalignment cloth can make the working roll bigger with the area of contact of backing roll, and it is undulant to make the working roll reduce when handling the not good belted steel of board type like this to improve life, the backing roll is crisscross to make the stress surface of backing roll be unlikely to too single, has increased the life of backing roll.

Description

Broken phosphorus supporting roller of straightening machine arrangement architecture

Technical field

The utility model is related to brokenly phosphorus withdrawal straightening machine accessory technical field and in particular to a kind of broken phosphorus supporting roller of straightening machine arranges Structure.

Background technology

Broken phosphorus withdrawal straightening machine is the visual plant before descaling bath in sour Continuous mill train, and the quality of cold rolling plate face pickling effect is directly Determined by broken phosphorus withdrawal straightening machine.Broken phosphorus withdrawal straightening machine can remove the iron scale of plate face, and improves template, thus reaching pickling effect Good result.Roller box on the support of descaling mill includes about two sets bending roll groups and a set of aligning roller group composition.In roller group Support roller using symmetrically uniformly arranging, during long-term rolled band steel, roller group upper backup roll unbalance stress, lead to strip table Face produces backing roll roll marks, or even produces flexural deformation.

Utility model content

The utility model provides a kind of broken phosphorus supporting roller of straightening machine arrangement architecture, to solve the support of prior art presence Roller symmetrically uniformly arranges unbalance stress and leads to belt steel surface to produce the problem of backing roll roll marks.

The utility model solves its technical problem and be employed technical scheme comprise that：

A kind of broken phosphorus supporting roller of straightening machine arrangement architecture, some support roller alternating expressions are arranged in the roller box on support.

The utility model support roller is staggered to make working roll bigger with the contact area of support roller, so can make work Make roller and reduce fluctuation in the bad strip of process template, thus improving service life；Support roller is interlocked and is made support roller Stress surface be unlikely to too single, increased the service life of support roller.

Brief description

With reference to the accompanying drawings and examples the utility model is further illustrated.

Fig. 1 is structural representation of the present utility model.

In figure 1 support, 2 roller boxes, 3 support rollers.

Specific embodiment

As illustrated, a kind of broken phosphorus supporting roller of straightening machine arrangement architecture, some support roller 3 alternating expressions are arranged on support 1 Roller box 2 in.

The utility model support roller is staggered to make working roll bigger with the contact area of support roller, so can make work Make roller and reduce fluctuation in the bad strip of process template, thus improving service life；Support roller is interlocked and is made support roller Stress surface be unlikely to too single, increased the service life of support roller.

Claims (1)

1. a kind of broken phosphorus supporting roller of straightening machine arrangement architecture, is characterized in that some support roller alternating expressions are arranged in the roller box on support In.
