The scalped slab is then placed inside the preheating furnace to be preheated / homogenized and made ready for the hot rolling process.The heated slab is hot rolled back and forward several times through the hot resersing mill to achieve a certain thickness prior to roll in the 1+2 Stand Tandem Mill.The finished products are hot rolled coils and plate materials for further process.
strip is going to enter the rolling mill. The least square method is used to fit the control curve, with the data of the points. After the curve fitting, the polynomial equation is sent to the PLC for the strip head and tail sharp control. The flow chart of the control model is shown as Figure II.
The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished steel slabs of steel nearly to their melting point, then roll them thinner and longer through 12 successive rolling mill stands driven by motors totaling 77,000 hp, and finally coiling up the lengthened steel sheet for transport to the next process.
A typical layout of a mill using the kraft chemical pulping process is shown in figure 2-1. Mechanical, semichemical, and sulfite pulp mills differ in detail, particularly in wood preparation, fiber separation, and bleaching, but many of the downstream refining, bleaching, and papermaking processes are similar.

pulp is such at this point that relatively hot water in a high velocity stream greatly expedites the work of dislodging and washing away the pulp. A typical application is an S&K Figure 320 heater to supply hot water hoses on machine room floors. Sample performance: 11/2" Fig. 320 continuous heater discharging 36 gpm of water at 120 F. Cold -
After this process, the product is referred to as HRPO ("hot-rolled pickled and oiled"). Cold Rolling Mill (CRM) The Cold Rolling Mill reduces the thickness of HRPO coils to the required thickness, with the percentage reduction ranging from 50 – 90%. After this process, the product is referred to as "cold-rolled" or "full-hard steel".

G. Engberg, L. Karlsson, in Fundamentals of Metallurgy, 2005 11.5.1 Hot rolling. Mill data from the hot strip mill has been used to calculate the mean flow stress in each pass, assuming the material to be elastic – ideally plastic. The roll force model used was a classical slab method with constant friction assumed in the roll gap. For the roughing mill (reversible 4-high) both roll force ...
