Two separate rolling mills are employed to process the raw steel blooms into rebars and highquality steel bars to be used in the automotive industry or in machine construction. To this end, the blooms are once again heated up in a pushertype or in a walkingbeam furnace respectively prior to hotrolling into the size requested by the customer.
#0183;#32;Hot rolling is a mill process which involves rolling the steel at a high temperature (typically at a temperature over 1700#176; F), which is above the steels recrystallization temperature. When steel is above the recrystallization temperature, it can be shaped and formed easily, and the steel can be made in much larger sizes.

Steel Hot Rolling Mills Temperature Monitoring Temperature Control in Hot Rolling Mills. Hot Rolling Mills are used to reheat shapes of steel to soften them enough so that they can be rolled thinner and longer through a series of rolling stands. The finished product can be either a strip, plate, rod, bar, wire, or shape (rails and Hbeams).
NOTE: Hotrolling and coldrolling should not be mistaken for different grades of steel. Steels of different grades can be produced as hotrolled or coldrolled. HOTROLLED STEEL. Hotrolling refers to a mill process in which you roll the steel at a temperature above its recrystallization temperature; a heat that typically exceeds 1000#176; F.
Hot rolling begins with heating the billet or blooms to a high temperature of around 1100 degrees Celsius. The temperature is of particular importance. Hot rolling and hot extruding drawing involves working above the recrystallization point of the steel. The mill passes the heated material through a variable number of stands.

ENDLESS ROLLING MILL ADVANCED SOLUTIONS FROM THE MARKET PIONEERS The concept of endless hot rolling was introduced to meet the increasing demands for hotrolled steel sheet using a costeffective process compared to the conventional batchtype process.
Rolling of steel in Hot Strip Mill. satyendra; December 3, 2015; 0 Comments ; AGC, edger, finishing mill, hot strip mill, Laminar cooling, rolling speed, scale breaker, slab. roughing mill, tension,; Rolling of steel in Hot Strip Mill. Hot strip mills in these days are either conventional hot strip mills or strip mills for rolling thin slabs.
#0183;#32;The oxide scale shows various behaviors in hot rolling; (a) uniform deformation with matrix steel, (b) cracking, (c) fragmentation, (d) indentation to matrix steel, etc.
Rolling processes date back to 1779. The first rolling mill was built in Fontley, Hampsire where Henry Cort developed and received patents for his ideas. The two types of temperaturedependent rolling processes are hot rolling and cold rolling, and they each have their own specific use. Hot Rolling
Our Hot Rolling Mills are flexible amp; offer custom sizes in Flat Bars, Angles, Hexagons, Squares amp; Round Bars in Stainless Steel grades 303, 304L, 316L, 416, 430F, 431 etc.
The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semifinished 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.
American Steel Products Leading the Industry in a Variety of Rolling Mill Lines. The hot rolling process is only done while at extremely elevated working temperatures, hence the name hot rolling. It is used to break down imperfections such as billets and ingots off of flat rolled steel coils.
