The thickness of strips rolled on the hot strip mill ranges from to, the maximum strip width is to, and the rolling speed of the final stand is about km/min. After hot rolling, hot rolled strips are cooled and coiled.

Methods and systems for scheduling work International ...

A method for scheduling work in a hot strip mill, comprising the steps: establishing conditions for all processing units in the host strip mill area and fir the available slabs in stock; group the slabs with similar routes, and identifying the critical sequences for each route; .

Hot rolling

The slabs heated to the temperature of hot forming are rolled by the rougher into transfer bars with a thickness of 24 36 mm (depending on the gauge, width and quality of the rolled sheet). The reversing roughing mill is composed of one vertical, socalled edging mill stand and one horizontal twohigh mill .

US Patent for Close coupled reversing rougher and ...

A hot strip mill includes at least one roughing reversing mill and a finishing train with the reversing mill spaced from the finishing mill by a distance greater than the length of the transfer bar on the penultimate pass but less than the distance of the final pass through the roughing reversing mill so as to be close coupled to the finishing train on that last pass.

USA Hot strip plant Google Patents

In this invention, a reversing roughing mill and a reversing finishing mill are disposed at such a distance that a material can reach the finishing mill only in the final pass of roughing, can thus prevent damage to and surface deterioration of finishing rolls in the roughing pass, can reduce the heat loss of the material located between the roughing mill and finishing mill and can produce a ...

Study of the longitudinal stability of strip made of ...

A method has been developed for experimentally studying the longitudinal stability of strip being rolled in vertical rolls on a strip mill with and without tension. The method makes it possible to study the effect of tension of the strip and reduction of its edges for different ratios of strip thickness to width. Quantitative results are obtained to evaluate the loss of stability and limiting ...

Width necking at the rougher in a hotstrip mill ...

Abstract The accuracy of the width of a hot strip is very important for the improvement of yield, both for the steel maker and the steel user. One of the important technical problems concerning width accuracy is securing a final hot strip with uniform width along the whole length. In the top or tail portion of a hot strip, a local contraction of width unavoidably occurs, called "width ...
