Description

Auxiliary deviation rectifying and adjusting structure for tension roller in furnace

Technical Field

The utility model belongs to the technical field of the metallurgical technology and specifically relates to an auxiliary deviation rectifying and adjusting structure of in-furnace tension roller.

Background

In the domestic metallurgical industry, on various continuous plate strip production lines with annealing furnaces: the continuous galvanizing unit, the continuous silicon steel production line, the continuous annealing unit and the like are accelerated to a high-speed unit from a conventional low-speed unit along with the gradual increase of the annual output of manufacturers, and the length of the annealing furnace is obviously lengthened.

A horizontal annealing furnace is usually equipped with a set of deviation-correcting device at the furnace inlet for deviation control of strip steel in the furnace. When the annealing furnace is lengthened and the running speed is increased, the strip steel still has the phenomenon that the strip steel at the outlet of the annealing furnace deviates from the central line of the unit in the high-speed long-distance running process in the furnace, the distance of the deviation rectifying equipment in front of the furnace is far, the deviation rectifying amount is limited, and the deviation problem of the strip steel at the outlet section of the annealing furnace cannot be completely solved. And an additional deviation correcting device cannot be additionally arranged in the furnace, so when the deviation phenomenon of the strip steel occurs in production, other means need to be considered for processing.

At present, the deviation of the strip steel in the annealing furnace is mainly controlled by a deviation correcting device at an inlet, and is assisted by the arrangement and the driving control mode of a furnace bottom roller. In production, the phenomenon of deviation of strip steel at the outlet of the annealing furnace can not be completely eliminated due to temperature fluctuation in the furnace and other comprehensive factors. Meanwhile, in order to ensure the stable operation of the strip steel in the annealing furnace, a set of thermal tension roller for providing the tension in the furnace is usually arranged at the outlet of the annealing furnace. The existing common thermal tension roller structure is only used for tension adjustment, does not participate in deviation rectification control, and cannot play other roles besides tension adjustment in strip steel deviation. The conventional bearing seat of the thermal tension roller is fixedly installed, and the angle offset of the roller body cannot be adjusted on line.

Therefore, an auxiliary deviation rectification adjusting structure for a tension roller in a furnace is needed to solve the technical problem.

The positions of two ends of the rotating shaft of the thermal tension roller 5 are respectively sleeved with a metal expansion joint 4, and the metal expansion joints 4 can compensate additional stress caused by temperature difference and mechanical vibration.

And a push-pull unit is arranged on the second roller support 7 and can push the sliding seat 11 to move linearly. The number of the thermal tension rollers 5 is not limited to one, each thermal tension roller 5 corresponds to one sliding seat 11 and one push-pull unit, and the matching structures at two ends of each thermal tension roller 5 are the same.

There are various embodiments of the push-pull unit, and two embodiments are described below.

The first implementation mode comprises the following steps: the push-pull unit comprises a driving assembly, a bearing seat 9 and a screw rod 10, wherein the driving assembly comprises an adjusting motor 8 and a reduction gearbox, the adjusting motor 8 is connected with the reduction gearbox, and an output shaft of the reduction gearbox is connected with the screw rod 10 through the bearing seat 9. The inside of slide 11 is provided with the screw hole, and the lead screw 10 imbeds inside the screw hole, and lead screw 10 and screw hole looks adaptation. When the adjusting motor 8 rotates, the screw rod 10 can be driven to rotate, so that the sliding seat 11 is driven to move, one end of the thermal tension roller 5 swings to form a deflection angle, an angle close to the vertical is formed between the central axis of the thermal tension roller 5 and the deviated strip steel, and the running direction of the strip steel is corrected.
