[0003] In the existing cooling system, due to the intermittent production in the strip steel production process, that is, the water spray cooling of the cooling system is in a discontinuous water spray state, and in order to ensure the timeliness of system response, the system water supply pump is generally opened continuously; For this contradiction between water supply and water consumption, the existing cooling system generally installs a pressure relief valve on the water supply pipe. When there is no need to spray water to cool the strip, the excess cooling water can be discharged through the pressure relief valve.
However, when the pressure relief valve is working, it will cause strong vibration of the water supply pipe, which is not conducive to the stability of the cooling system

The invention relates to a strip steel cooling system. The strip steel cooling system comprises a spraying mechanism and a water supply mechanism supplying water to the spraying mechanism. The water supply mechanism comprises a water supply pump and a plurality of water supply branch pipes which are arranged in parallel. A three-way valve is arranged on each water supply branch pipe. Each three-way valve comprises an inflow port and two outflow ports. The inflow ports are communicated with the water supply pump. One outflow port of each three-way valve is communicated with the spraying mechanism. The other outflow port of each three-way valve is connected with a drainage pipe. The cooling system is high in stability, cooling capacity and cooling precision and capable of effectively improving the performance of strip steel products.
Description
Technical field [0001] The invention relates to the technical field of cooling of hot rolled strip steel, in particular to a strip steel cooling system. Background technique [0002] It is an effective way to develop hot-rolled products to improve the properties of rolled products by controlling cooling after rolling. In recent years, with the continuous demand for high-strength steel grades, it is particularly important to improve the cooling capacity of the cooling system. Due to the improvement of the cooling capacity, the length of the cooling zone of the cooling system is shorter, so the arrangement of the cooling system equipment is restricted. The common laminar cooling system adopts a separate flow control valve for each spray tank to control the flow rate. In order to improve the control accuracy of such a high-strength cooling system to adapt to specific cooling processes of different steel grades, it is necessary to improve the layout of the cooling system. [0003] In...
