Intelligent with-tension deep cooling friction speed asynchronous experiment rolling mill of single-chip strips and rolling method

Abstract

The invention relates to an intelligent with-tension deep cooling friction speed asynchronous experiment rolling mill of single-chip strips. The intelligent with-tension deep cooling friction speed asynchronous experiment rolling mill comprises a friction speed asynchronous rolling mill frame and a thermotank, wherein rolling pieces are single-chip strips; the moving direction of the rolling pieces is the left-and-right direction; a left side box body and a right side box body of the thermotank are symmetrically buckled to the friction speed asynchronous rolling mill frame from the left side and the right side, so that supporting rollers and working rollers of the rolling mill are located in a box; a left side working platform is arranged in the left side box body; a hydraulic clamp I is arranged on the left side working platform; a right side working platform is arranged in the right side box body; a hydraulic clamp II is arranged on the left side working platform; two ends of the rolling pieces are respectively clamped by the hydraulic clamp I and the hydraulic clamp II; and cooling gas and lubricating liquid input pipelines enter the box from pipeline inlet and gas outlets in the left side box body and the right side box body, and are respectively connected with a corresponding cooling gas and lubricating liquid nozzle at a roll gap entrance and exit. Through the adoption ofthe intelligent with-tension deep cooling friction speed asynchronous experiment rolling mill disclosed by the invention, the usage amount of liquid nitrogen or cooled nitrogen gas can be effectivelyreduced, besides, with-tension deep cooling friction speed asynchronous rolling can be realized, and the operation of the rollers is still under the deep cooling condition is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of metal material rolling, and in particular relates to an intelligent deep-cooling different-speed asynchronous experimental rolling mill and a rolling method for a single strip with tension. Background technique [0002] Ultrafine-grained metal materials have attracted extensive attention from academia and engineering circles in the past 20 years, and a large number of large plastic deformation methods have been opened up to study and prepare ultrafine-grained metal materials. Among them, cryogenic asynchronous rolling is one of the methods. Cryogenic asynchronous rolling uses liquid nitrogen or nitrogen to cool the rolled piece, and then roll it immediately. At the same time, nitrogen is used to cool the rolls. However, when nitrogen is directly used for cooling in the atmospheric environment, nitrogen volatilizes immediately, resulting in a large waste of energy and greatly increasing the manufacturing...

Problems solved by technology

However, when nitrogen is directly used for cooling in the atmospheric environment, nitrogen volatilizes immediately, resulting in a large waste of energy and greatly increasing the manufacturing cost of cryogenic asynchronous rolling

In addition, as the cryogenic asynchronous rolling experiment traditionally uses coils for rolling, this will cause a lot of waste for laboratory research
