Background

A hot continuous rolling technology for manufacturing steel plate, flat coil and longitudinal cut steel band includes such steps as heating the plate blank (continuous casting blank), coarse rolling to obtain steel band, finish rolling to obtain hot steel band, laminar cooling, coiling, and finishing. The hot continuous rolling steel plate product has excellent performances of high strength, good toughness, easy processing and forming, good weldability and the like, so the hot continuous rolling steel plate product is widely applied to the manufacturing industries of ships, automobiles, bridges, buildings, machinery, pressure vessels and the like. With the increasing maturity of new control technologies of hot rolling size precision, plate shape, surface quality and the like and the continuous emergence of new products, hot continuous rolling steel plates and strip products are more and more widely applied and have stronger and stronger competitiveness in the market. It becomes important to improve the production efficiency of the hot continuous rolling process and the performance of the hot continuous rolled product.

In industrial production, the laminar cooling zone of a hot continuous rolling apparatus usually has a plurality of rolling mills, and the main components of each rolling mill are upper and lower working rolls and upper and lower supporting rolls. In the production process of steel rolling, corresponding upper and lower collecting pipes are arranged beside an upper working roll and a lower working roll, the collecting pipes spray water through spray heads, and when strip steel enters a laminar cooling area through a roller way, the upper and lower collecting pipes spray water to cool the upper and lower surfaces of the strip steel according to set flow and pressure so as to ensure that the coiling temperature of a steel coil meets the requirements of customers; typically the spray heads are arranged in rows along the axial direction of the work roll and a plurality of spray heads are arranged in each row; the spray head uninterruptedly sprays water to the surface of the strip steel so as to realize the purpose of cooling the strip steel. However, in actual production, scale is generated after the upper header is operated for a certain period of time, and impurities and scale in water block the water spray holes of the header. In addition, impurities such as oxide scales on the roller way fall into the lower collecting pipe to cause blockage. The blockage of the spray head of the upper collecting pipe can cause poor cooling effect of the strip steel and seriously affect the quality of the strip steel. The traditional solution is that, by using the maintenance time, an operator stands on a roller way, and each water spraying hole is manually cleaned through an electric drill, so that the method is low in efficiency and lacks of guarantee for the safety of operators.

The normal operating of shower nozzle can be ensured to this device, avoids using sewage to cool down and causes the problem of blockking up the shower nozzle. However, the device judges the used water quality through the PLC, so that the water flowing through the spray head is not easy to scale, and the blocked upper collecting pipe spray head is not treated.
