Problems solved by technology
[0004] 1. The device has a simple structure and poor sealing performance. When spraying, the emulsion overflows through splashes, which pollutes the workshop environment and is not conducive to the recycling of rolling emulsion.
Moreover, the emulsion is slippery, which brings safety hazards to the production environment of the workshop
[0005] 2. The injection pressure of the device is low, which cannot form enough striking force, which affects the descaling effect and thus affects the surface quality of the finished product
[0006] 3. The nozzle has no filtering and flow stabilization function. After a period of use, the nozzle is prone to clogging, which increases the difficulty of later maintenance.

A novel high-pressure water descaling device is provided with a high-pressure liquid supply system, a descaling box and a nozzle beam. The high-pressure liquid supply system comprises a high-pressure pump, an energy storage device and an emulsion tank which are connected in sequence, and the emulsion tank is used for providing high-pressure emulsion for the nozzle beam; the descaling box is provided with an upper box body and a lower box body, and the upper box body and the lower box body can be opened and closed under the action of a hydraulic cylinder; and one group of nozzle beams is arranged in the upper box body, and the other group of nozzle beams is arranged in the lower box body. And the descaling box can prevent the emulsion from splashing to pollute the environment, so that the safety of the production environment is guaranteed. And the descaling rhythm is accelerated through opening and closing of the dephosphorization box, and maintenance of the nozzles is also facilitated. The high-pressure liquid supply system can provide stable high pressure for the nozzle beam, and the nozzle beam can form planar jet flow. No dead angle is left when the planar jet flow is jetted on the surface of the copper strip blank, and the planar jet flow has larger impact force and smaller impact surface, so that the descaling effect is good, the heat loss of the copper strip blank is small, and the control on the rolling temperature is facilitated.
Description
technical field [0001] The invention relates to the field of metal rolling, in particular to a novel high-pressure water descaling device. Background technique [0002] Copper strip blanks are usually heated in a heating furnace before rolling, and a large amount of metal oxides will appear on the surface of copper strip blanks. In order to prevent metal oxides from being pressed into the interior of the copper strip blank during rolling, a high-pressure water descaling device is usually installed near the left and right entrance roller tables of the rolling mill to remove the metal oxide on the surface of the copper strip blank. things. [0003] Such as figure 1 As shown, the traditional high-pressure water descaling device is equipped with a booster pump, a pipeline 9 and a spray beam 1 in the existing rolling mill process lubrication system. The spray beam 1 is equipped with a nozzle, and the nozzle sprays emulsion to the copper strip to remove Metal oxide. It has the...
