AI Technical Summary

Technical Problem

During the hot rolling process of galvanized strip steel, the service life of the rolling roll is greatly reduced due to the long-term high-temperature and high-pressure load environment, and it is easy to cause the rolling roll deformation, affecting the rolling quality of the strip steel.

Method used

A galvanized strip production and rolling equipment is designed, including rolling rolls, cooling chambers, air coolers and air outlet ducts. The cold air is introduced into the roll cooling chamber through the cold air, taking away the heat of the roll, and converting the heat into hot air for preheating or drying.

Benefits of technology

It effectively reduces the temperature of the roll, extends the service life of the roll, improves the rolling quality of strip steel, and saves energy consumption.

Abstract

The utility model relates to the technical field of strip steel rolling, in particular to galvanized strip steel production rolling equipment. According to the technical scheme, the device comprises an air outlet pipe, a fixing frame, rollers and an air cooler, the rollers are symmetrically and rotationally installed in the positions, close to the upper surface and the lower surface, of the interior of the fixing frame, cooling cavities are formed in the two rollers, and the two ends of each roller are fixedly connected with a rotary joint A and a rotary joint B correspondingly; connecting pipes A are fixedly connected to the outer sides of the two rotating joints A, the tail ends of the two connecting pipes A are fixedly connected to the outer surface of an air outlet pipe, and an air inlet pipe is fixedly connected to the tail end of the air cooler output pipe. In the hot rolling process of the galvanized strip steel, the temperature of the roller is reduced, the service life of the roller is prolonged, heat of the roller is converted into hot air, production raw materials needing to be heated can be preheated, meanwhile, the hot air drying device can be used for drying the galvanized strip steel after follow-up cleaning operation, and energy consumption is saved.
