Rolling system

Abstract

A cooling method of a rolling system is disclosed. Upper and lower supporting rollers are cooled through a cooling pipe and a cooling water tank by adjusting intensity or flow of a cooling medium and water, and the supporting rollers conduct to cool a working roller so as to realize the purpose of cooling the rolling system efficiently. The invention also provides a rolling cooling system which comprises the supporting rollers, the working roller, a first cooling component which comprises the cooling pipe used for cooling the circulating medium and rotationally contacted with the supporting roller at the upper side and a circulating device communicated with the cooling pipe, and a second cooling component which comprises a cooling water tank and a circulating pipe system, wherein the circulating pipe system is communicated with the cooling water tank; the cooling medium is arranged in the cooling water tank; and the supporting roller located at the lower side is soaked in the cooling medium. The supporting rollers are cooled through the first cooling component and the second cooling component; and the supporting rollers at a low temperature are in contact with the working roller to realize the purpose of cooling the working roller efficiently.

Description

technical field [0001] The invention relates to a roll system. Background technique [0002] In the usual rolling production, the spray cooling method is used to cool the roll, and the cooling medium includes water, 5% emulsion or full oil. [0003] The micro-oil "dry lubrication" used in the cold composite roll of the two metals is almost a "dry lubrication" roll that is carried out without cooling medium at all; [0004] Due to the particularity of metal clad rolling, the spray cooling and lubrication method is completely inapplicable to the cooling method of metal clad rolling. Therefore, the cooling method generally uses hollow work rolls to pass water or fans to cool the rolls. [0005] Due to the restriction of the strength of the rolls, the water flow through the hollow work rolls cannot be large enough, and the water flow rate is not enough to continuously cool the work rolls; [0006] Due to the restriction of the ambient temperature, the fan blowing cooling is no...

AI Technical Summary

Problems solved by technology

[0006] Due to the restriction of the ambient temperature, the fan blowing cooling is not enough to effectively and continuously cool the temperature rise of the roll system;

[0007] Therefore, neither of the above two cooling methods can fully and continuously effectively solve the problem of roll production convexity caused by the continuous rise of roll temperature, especially in spring, summer, and summer and autumn, the temperature rise and cooling of the roll system is particularly important.

[0008] In summary, how to design a new cooling process device system and method that can effectively and continuously solve the thermal crown problem of roll production caused by the temperature rise of the roll system in the metal clad rolling process has become an urgent need for those skilled in the art. the primary problem to be solved
