ODHla6qY) This film takes you through the processes within a hot rolling mill. ThyssenKrupp Steel Europe spent a quarter of a million euros on renovating its hot -strip rolling mill in. Weiter zu Iron and steel – 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 6BCE.
Earliest rolling mills were slitting mills, which were introduced . Hot Rolling Mill – ,rh:.

They are designed to produce flat steel from thin strip with a minimum final gauge of 1. Implemented here are many . Customers often ask us about the differences between hot rolled steel and cold rolled steel.
There are some fundamental differences between these two types of metal.
These differences relate to the ways these metals are processed at the mill , and not the product specification or grade. The slabs cool outside before being reheated in the reheat furnace. The slab ( 2mm thick and weighing over tonnes) is then transferred into the reversing rougher mill and is reduced in thickness with each pass. The steel is rolled down to about mm when it is coiled in the coil box (to retain heat).
Powerful drives and reliable automation systems, in combination with precise and flexible process models, optimize the rolling process from the reheating furnace to the downstream area. Our solutions are suitable for new mills as well . ENDLESS ROLLING MILL – ADVANCED SOLUTIONS FROM THE MARKET PIONEERS. The concept of endless hot rolling was introduced to meet the increasing demands for hot -rolled steel sheet using a cost-effective process compared to the conventional batch-type process.
Endless rolling involves the joining of the tail . Rolling is today one of the most important industrial processes because a greater volume of material is worked by rolling than by any other technique. Roll wear is a multiplex process where mechanical and thermal fatigue combines with impact, abrasion, adhesion and corrosion, which all depend on system interactions . Here, slabs are pulled to make steel strips. The rolled strip steel is then wound up like a roll of toilet paper ( called a hot coil). In rolling mills , intermediate steel products are given their final shape and dimension in a series of shaping and finishing operations.
Most of the slabs are heated in reheating furnaces and rolled into final shape in hot – or cold–rolling or finishing mills. While some products (e.g. reinforcement bars, steel plates) only require . Ordinance on Waste Water (Abwasserverordnung).
Water Pollution Control Levy Law (Abwasserabgabengesetz). Public Limited Company, plc. Best Available Techniques. Federal Immission Control Act (Bundes-Immissionsschutzgesetz).
Whether in the conventional hot strip mill , the CSP facility or in the Steckel rolling mill – the grinding of work and backup rolls with or without in chocks is nowadays state-of-the-art technology for WaldrichSiegen grinding machines. Especially the turning of large workpieces in the machine requires tremendous center heights. After leaving the last finishing stan of the hot strip mill , the rolled strip is delivered across a runout table that is equipped with top and bottom cooling sprays.
By controlling the amount, location and flow of cooling water to which the strip is expose the mechanical properties and shape of the hot rolled strip can be affected. Video created by Pohang University of Science and Technology for the course Ferrous Technology I.
