Description

Technical Field

[0001] The utility model relates to the technical field of thin plate braking, in particular to a belt head braking device for a continuous retreat cleaning section. Background Art

[0002] After the continuous retreat entrance welding machine welds, it is necessary to build a strip and start the car to the digging edge to cut the digging edge. In the early stage, there were many accidents in which the strip was disconnected in the heat induction area after the strip was built. Once the strip was disconnected, the cleaning tension could not be withdrawn in time. The entrance tension roller brake alone could not play a braking role, causing the strip to be forced forward. If there is no external intervention, the strip will be pulled into the cleaning section box, and the unit will be forced to shut down. The manhole door of the cleaning section box will be opened manually to take the lead and pull the strip back to the welding machine for welding, which will seriously affect the normal operation of the unit.

[0038] Example

[0039] like Figure 1 As shown, the utility model provides a continuous retreat cleaning section belt head braking device. The braking device is installed on the first steering roller of the cleaning section, which can effectively reduce the unit shutdown accidents caused by the inlet belt head being dragged into the cleaning section box, thereby improving the unit operation efficiency.

[0040] The lifting and lowering of the pressure roller is controlled by an electrical signal switch. When the unit speed is lower than 30m / min, or the unit is in a fault state, or the steel plate weld is in progress, the rodless chamber of the cylinder is ventilated, the cylinder rod extends, driving the pressure roller downward and the swing arm to move; when the unit resumes normal operation, the rod chamber of the cylinder is ventilated, the cylinder rod retracts, driving the pressure roller to lift; the synchronous operation of the pressure roller and the steel plate is controlled by a program.

[0041] After the improvement, the number of shutdown accidents caused by the strip head being dragged into the cleaning section is reduced by an average of one per month. The total length of the continuous annealing furnace area is 2100m, the length of the heating section and the soaking section is about 600m, the average length of each coil of continuous annealing strip is 2800m, and the average coil weight is 23.5 tons. Therefore, about 5.04 tons of waste are generated due to the temperature mismatch between the speed reduction heating section and the soaking section. The price difference between the genuine product and the waste is 22,460 yuan, and the annual benefit = 5.04*4*0.2246*12 = 135,800 yuan.
