Product description Skin passing is characterized by a small strip elongation process of between 0.2 and 3.0%, but temper rolling provides greater elongation of up to 12%. A a new lateral movement model (LMM) for temper rolling is derived from the approximation model for cold-strip rolling, considering the temper rolling reduction is very small.

A temper mill is a finishing equipment that processes steel strips in order to give them added strength and uniform flatness to the surface. The metal forming method at a temper mill involves rolling steel strips through a cold reducing process or temper pass. This increases the density of the steel by reducing its overall thickness betweenSingle or double-stand Skin-Pass Mills are placed in-line at the exit of continuous annealing and continuous galvanizing lines. 6-high UC-MILLs are supplied in response to recent requirements to roll harder material, such as hard tin plate and AHSS, with improved strip flatness control capability. Main benefits: Tight strip elongation tolerances.Skin-Pass Mill Solutions by Primetals Technologies

In Southeast China, SEHPS is the major hot rolling mill supplier with the greatest capacity of forging and casting. The largest net weight of mill housing built at SEHPS is 430 tons for Shougang Jingtang.In terms of our own development and research, SEHPS designed and manufactured thin-strip casting rolling mill for HEIBEI JINYE (first Abstract. Two and four degree of freedom (DOF) systems describing chatter in sheet rolling are investigated. In the two DOF case, this includes studying the nonlinear behavior that arises due to the deformation at the work-backup roll interface.

Section snippets 250 high-stiffness rolling mill. To develop an analytical method for spatial vibration analysis of rolling mill, a 250 mm (diameter of the roll) high-stiffness rolling mill (without housing) is taken as an object for analysis.As shown in Fig. 2, the upper and lower chocks are connected by two square columns and two rods with left rolling mill was derived analytically using the factors causing negative and positive damping [8]. However, up till now, to remove chatter completely remains unsuccessful. Hence, it is a great challenge to reduce chatter from Relative movement between strip and roll (b) Lubricating performance of temper fluid (c) Stability of friction A Review on Chatter Analysis in Cold Rolling process

Skin pass rolling experiments were performed on a laboratory rolling mill in a two-high configuration, with roll diameter of 136.5 mm and width 200 mm. The surface roughness of the rolls was Ra = 0.16 mm and Rz = 1.42 mm. The rolling speed was adjusted at two different levels: 1500 mm/min and 4600 mm/min.Applications: These rolls are suitable for Intermediate and Finishing Mill stands for TMT Bar Mills, Rail and Structural mills.
