Description

technical field

[0001] The invention relates to a rolling heat preservation device, which can change the shape of the heat preservation cover according to the size of the conveyed material to improve the heat preservation effect. Background technique

[0002] The material for rolling is transported to the rough rolling process after being heated to about 1300-1400° C. in a heating furnace. When the material heated as above goes through the rough rolling process, its temperature drops to about 900-1100° C. due to the influence of cooling water or the atmosphere, and a temperature deviation in the length direction appears as the length increases.

[0003] The material after the rough rolling process is transported to the finishing rolling process along a conveying line (roller table) of about 100 meters. During this process, the temperature of the material drops further due to air cooling. Based on the rolling time point in the finish rolling process, the temperature deviati...
