Description

Technical Field

[0001] The utility model belongs to the technical field of stainless steel plate production, in particular to a device for improving the washing of oxide scales of austenitic stainless steel red-hot billets. Background Art

[0002] During the heating process of the billet in the production of stainless steel plates, a large amount of oxide scale will be produced on the surface of the billet, which needs to be cleaned. The most common treatment methods are water descaling and roller brush descaling.

[0003] After searching, the prior art announcement number is CN 218692635 U. A high-pressure water dephosphorization device includes a dephosphorization box, a conveying assembly, a dephosphorization assembly and a steel brush. The conveying assembly runs through the dephosphorization box and is used to convey the steel billet. The dephosphorization assembly includes a water tank, a spray pipe and a nozzle. The water tank is located on the dephosphorization box, the spray pipe is connected to the water tank, and the nozzle is arranged on the spray pipe, and the nozzle is located in the dephosphorization box. This technical solution adopts a common water descaling method; however, the use environment of the nozzle and the nozzle is relatively single, and adaptive adjustment cannot be performed to adapt to the flushing of different types of steel billets.

[0004] After searching, a device for descaling a stainless steel slab with a prior art announcement number of CN 217095595 U is found. The device transports water inside a water tank to a nozzle along a water pipe through a water pump, and sprays the water from the nozzle onto the surface of the stainless steel slab to wash away the scales on the surface of the stainless steel slab. The scales flow into the lower water tank along with the water, and the water passes through the filter screen into the water tank. The scales are blocked by the water tank and remain in the lower water tank. The water forms a cycle between the water tank, the water pump, the water pipe, the nozzle and the first roller, so that the water can be recycled, thereby improving the utilization rate of water and avoiding the waste of water resources. The water tank is removed, the filter screen is removed, and the accumulated scales can be taken out, so that the scales can be collected together to avoid the scales polluting the environment. The disadvantage is that when the filter screen accumulates oxide scale, the water tank needs to be removed and the filter screen needs to be removed to remove the oxide scale. The cumbersome process leads to low efficiency in the recycling and use of water resources. Summary of the invention
