In the hot strip rolling process, accurate prediction of bending force can improve the control accuracy of the strip flatness and further improve the quality of the strip. In this paper, based on the production data of 1300 slitting mill with series of disc cutters to slit flats into narrow strips. As per record available, rolling of iron into thin flats was first done in Bristol, the UK in 1666. As per a pamphlet on ‘British Iron Trade published in 1725,’ all bars were made by hammering even at that date. By 1682, large rolling mills for hot rolling ofIntroduction to Rolling Process Cambridge University
Before we can start rolling out the slabs, they need to be heated until they reach a temperature of around 1.000° to 1.270° C. This is done in the reheating furnaces of the hot strip mill. A slab coming out of the furnace Downcoiler is one of the major facilities in hot strip mill operation. The key to good coiling is having good equipment, modem control systems, excellent maintenance and an understanding of coiling process. This study aims to develop a program that is useful for simulating coiling process and develop the improved coiling control method.Coiling Simulation and Control Method for Hot Strip
The hot metal is converted into steel through a steelmaking process called the LD process. Flat Products: The steel is cast into slabs, which are then rolled into hot rolled coils in the Hot Strip Mill & Thin Slab Caster. Some of the hot rolled coils are further rolled into cold rolled and galvanisedcoils in the Cold Rolling Mill. Long Products:Figure 3 shows the flow chart for the determination of the gap during hot rolling by involving the hybrid mill set-up model.

The production process for metallic coated and organic coated steel begins with the pickling or cleaning of hot-rolled coils in order to remove the iron oxide scale which is formed during hot rolling of steel. The Cold Rolling Mill reduces the thickness of HRPO coils to the required thickness, with the percentage reduction ranging from 50Download scientific diagram Hot strip rolling mill layout from publication: Disturbance Rejection in iron and steel process: Problems and current solutions It is shown in this paper that theHot strip rolling mill layout Download Scientific Diagram

With a view to the wide size range of the hot rolled strip thicknesses from 1.5 mm to 20 mm, width from 750 mm to 2200 mm as well as the conditions and costs for maintenance of the coiler station, a three OVERVIEW OF THE HOT STRIP MILL PROCESS Algoma's Mill. The hot strip rolling complex at Algoma consists of the following units as depicted in Fig. 1 and 2: two 220-tonne/hr walking beam reheat furnaces; a 3150 mm (126") wide, 3000 kw (4000 hp), 2 Hi reversing rougher with close coupled vertical edgers; a 4150 mm (166") wide, 7350 kw Design Requirements for a Hot Strip Mill Process Computer
During the hot strip tandem rolling (HSTR) process, the strip is compressed and elongated continuously, causing significant elastic deformation of rolls. At the same time, the strip temperature undergoes rapid increase and decrease, and distributes unevenly along the strip width direction. Elastic deformation of rolls and strip temperature Mill designers and operators are keenly interested in proper design and control of the hot strip rolling precess. The specific goals to be achieved by process design and control may vary depending on the need of the manufacturers and customers, but product quality as well as production economy is a fundamental consideration in most cases.Strip Rolling an overview ScienceDirect Topics
A schematic layout of the hot strip mill is shown in Fig. 5 . According to Fig. 5,the industrial HSMP basically consists of 6 subunits in turn: reheating furnaces, roughing mill, transfer tableSteel factory hot rolling mill problem definition. The function of the hot rolling mill is based upon the simple mechanism of using rolls to press steel slabs and reduce their thickness, as illustrated in Fig. 3. Before slabs can be rolled into hot rolling mills, slabs should be heated to the deformation temperature using reheating furnaces.A review of planning and scheduling methods for hot rolling mills
