The rolling steel inlet and outlet water cooling guide refers to the device that uses the water cooling system to cool the rolling mill during the steel rolling process. It is mainly composed of two parts: the water inlet guide and the water outlet guide. The water inlet guide is used to introduce cooling water into the rolling mill to reduce the temperature of the rolling mill and prevent overheating. The water inlet guide is usually located at the entrance of the rolling mill, and the cooling water is evenly sprayed on the rolling mill through the nozzle to form a film-like water film, so that the surface of the rolling mill can quickly dissipate heat. The water outlet guide is used to discharge the cooled water out of the rolling mill to keep the cooling water circulating. The outlet water guide is usually located at the outlet of the rolling mill, and the cooling water is discharged through the drainage pipe, and is recycled after treatment. The role of the rolling steel inlet an…
