Background
The steel industry is commonly provided with corresponding descaling processes during slab hot rolling, including traditional blasting, mechanical crushing, plastic deformation and the like, and the descaling process is used for removing primary and secondary scale formed in a heating furnace in the previous working procedure, so that the surface quality of a rolled material is improved. The hot rolling descaling at home and abroad generally adopts high-pressure water based on the fluid mechanics principle to remove primary and secondary iron scales, and the mechanical impact force of the high-pressure water is used for removing the iron scales, so that the method is the most economical descaling method, is uniform in form, has larger difference in arrangement and is mainly determined according to the rolling process of products, the shapes of the products and the requirements of product standards.
In the actual use process of the existing water dephosphorization equipment, the descaling effect is often found to be remarkably reduced after a period of use. It has been found that this is mainly due to the blockage of the spray head inside it. Because during water descaling, high pressure water jets form mechanical impact to remove scale, but form oxide dust, because the atomized droplets do not overflow and are largely able to flush out for collection, the problem of head clogging is not initially recognized. The researchers of the invention find that when the actual oxide dust is affected by the atomized liquid drops to sink and is flushed, a small part of the oxide dust is actually accumulated in the nozzle under the influence of the water tension on the surface of the nozzle, and especially in a short period of time after the operation of the nozzle is finished, a sufficient amount of atomized liquid drops are not needed to enable the oxide dust to completely sink and flush, and a large amount of oxide dust enters the nozzle and is deposited in the nozzle, and then the oxide dust is dried and solidified. In the past, can block up in the nozzle and fill a large amount of firm plugs, lead to the water yield of shower nozzle to reduce, easily damage to this plug is not in time clear away then can be continuous accumulation and firm more, to the last mode that only can be through whole change shower nozzle maintains water dephosphorization equipment. Greatly improves the maintenance cost and maintenance frequency of the water dephosphorization equipment, and causes unnecessary waste.
Therefore, how to improve the spray heads in the water dephosphorization equipment is the key of the invention.
