Skin Pass Mills. The device uses skin pass rolling to improve the mechanical properties and surface texture, and improve flatness, in order to form materials such as hotrolled steel sheets, coldrolled steel sheets, stainless steel plates, and aluminum plates into final products. Since it conducted tests with its own test equipment in 1965 ...

The coldrolled ribbed steel bar rolled by cold rolling mill is an updated product of cold drawn lowcarbon steel wire in prestressed concrete members. In castinsitu concrete structure, it can replace grade I steel bar to save steel. It is a better kind of coldworked steel of the same kind. If speed regulation is not required in the rolling ...
Coldrolling mill The 5stand 6high UCMW is equipped with workroll shifting to compensate for edge drop. The UCMW mill concept for shape control also includes workroll and intermediateroll bending, as well as intermediate roll shifting.
I'm working on a tension leveller design which consists of 3 main sections. These are. Input Bridle Rolls Zone: Increase the strip tension coming out of the decoiler. Leveller Zone: Strip goes through reversed bendings and gets plastically deformed under tension. Output Bridle Rolls Zone: Decrease the strip tension to recoil. Both 1. and 3. sections use srolls.

This is article is part 1 of a fourpart series covering flatness and stability in cuttolength, slitting, and tension leveling operations. This article covers how flat rolled metal gets unflattened, including the 3 categories of defects, how defects are created at hot and cold mills, and how coil processors also create defects.

Tandem cold rolling is a highspeed, highefficiency, and complex production process. In some cases, minor interference or disoperation may result in large economic losses. To improve control performance and enhance system robustness, an optimal tension and thickness control method is presented in this paper.

Fig 1 A pair of grooved rolls. Rolls are required to take all type of stresses, loads from normal and abnormal rolling conditions in the rolling mill and the stresses which are changing with roll wear during rolling. Rolls are required to carry out the heavy work of reduction during hot and cold rolling. Roll design is required to take care of ...
Tension bridles for a cold rolling reducing mill are provided. The reducing mill reduces the thickness of a metal strip passing through the reducing mill. The tension bridles create tension on the metal strip between the bridle and the first reducing stand to receive the metal strip and between the final reducing stand and the exit bridle so that a greater reduction can be made in the ...

Abstract. According to the present invention, a snubber roll for holding a steel sheet refracted by the bridle roll in transferring a steel sheet such as a cold rolled coil strip to a transport wheel such as a bridle roll can be stopped at the same time without an operation delay when the bridle roll stops. It is related with the snubber roll ...

The focus of the paper is on the tensionlevelling operation which is one of the first that is performed in the rolling mill and can have a relevant influence on the strip mechanical characteristics. To reach this aim, a predictive model applicable to the tensionlevelling process was developed, as this process is used to minimize flatness ...
