Wrapper Roll Control System of Hot Strip Mill 2018-10-14 Wrapper roll is one of the most important components in rolling coiler. And it has great relation to the quality of the final products. Based on the programming and optimization experience, a hot strip coiler

speed of the hot run out table, pinch roll and wrapper roll is less than the speed of strip, the value of lag rate is given in man-machine interface by the console. In the process of the whole tension control and speed control switch,

Equations are derived for the normal roll pressure, specific roll load and torque in hot rolling mills, using the condition for plastic deformation in rolling derived by Orowan, together with von Krmn's equation of equilibrium. Although applying strictly to the rolling of

P. Kucsera et al. Hot Rolling Mill HGC Thickness Control Improvement – 98 – Another way to determine the thermal expansion of the work roll is the modelling of the heat transfer between the work rolls and the strip. This depends on the roll speed, strip thickness

Hot rolled steel and cold rolled steel both have their uses and advantages deriving from their respectibe manufacturing methods. As opposed to hot rolling, cold rolling occurs with the metal below its temperature of recrystallisation. This is still only half the truth.

You'll appreciate X-Roll hot strip mills from SMS group as all-round plants for high-quality hot strip. They are designed to produce flat steel from thin strip with a minimum final gauge of 1.2 millimeters to high-strength pipe steels up to 25.4 millimeters thick

The invention of the rolling mill in Europe may be attributed to Leonardo da Vinci in his drawings. The earliest rolling mills in crude form but the same basic principles were found in Middle East and South Asia as early as 600 BCE. Earliest rolling mills were slitting mills, which were introduced from what is now Belgium to England in 1590. . These passed flat bars between rolls to form a

steel strip. Accelerated cooling has been implemented in hot strip mills to reduce the heat loss on the delay table, to achieve the required coiling temperature and to obtain the desirable grain stru cture. Appropriate cooling application with better understanding of

Roll Gap Lubrication System For Hot Strip Mills

4 Roll wear is inherent during hot rolling •Abrasion with the oxide layer of the strip and the particles detached from the roll •Adhesion of scale or strip to roll and consequent detachment or simply adhesion of roll particles to strip. •Surface fatigue, by thermal and mechanical crack

roll bite and in a typical Cold Tandem Mill, work roll temperatures normally fall in the range of 55oC – 70oC with strip recoil temperatures and inter-stand strip temperature rarely exceeding 160 o C depending on product.

1 INTRODUCTION In the early 80s, the Chrome steel work roll grade was developed by European rollmakers and introduced since then in most of the existing roughing stands of hot strip mills (HSMs) as well as into the early finishing stands of compact strip mills.

Hard chrome plating rolls for cold rolling and skin-pass 2006 Q. Dear All, I work as a process engineer in a cold rolling company in Egypt. I want to make a trial of chrome plating our work rolls that are used to cold roll carbon steel sheets.

SMS DEMAG Hot Strip Mills 4 A slab sizing press in the roughing mill area offers decisive advantages for more flexibility in hot strip pro-duction today and in the future. Width reductions of up to 350 mm in one pass enable the number of different casting sizes in the

1. Hot rolling and rolling defects: 1.1 Front and back tensions: We have seen that the rolling load is dependent on roll diameter, higher the roll dia, higher the roll force. Similarly, smaller reductions requires lower roll force. In order to reduce the roll force, we can
