John G. Lenard, in Primer on Flat Rolling (Second Edition), 2014 2.7 Generation III – Coil Box Hot Strip Mills. In the 1970s, Stelco of Canada developed the hot coil box designed for installation in hot strip mills ahead of the finish mill for coiling the transfer bar from the roughing mill and uncoiling it into the finishing mill. The coil box reduced the distance between the roughing mill ...
predominantly defined during the processes in the hot strip mill (HSM). In this plant, steel slabs of typical dimensions L x W x H = 12 m x 2 m x 0.22 m are heated in
Critical to the Hot Strip Mill is its walking-beam reheat furnace, state-of-the art equipment that replaced and now outperforms three older- (pusher-) style furnaces. Nominally rated to produce 270 tons-per-hour, improvements in efficiency and some sace in slab temperature uniformity enable extended production rates 25% above design.

hot-strip mills are the reduction of strip-width deviations and the avoidance of below-minimum widths after the finish-ing mill, which is why Primetals Technologies has devel-oped model-based strip-width control. Recognizing that tension can be used to manipulate the strip width in the finishing mill, model-based width control compensates

Measures strip and sheet temperature to efficiently set up the rolling mill to match the steel's temperature. These sensors also detect the presence of hot metal to accurately time the roll stand operation for maximum efficiency. LumaSense IS 320 Pyrometer, 150C TO 1200C and LumaSense IGA 320/23, 200C TO 1800C were utilized.

2. The Evolution of Microstructure in the Hot Rolling Process The layout of the hot strip mill of voestalpine Stahl is shown in Fig. 1. Slabs are heated to rolling temperature in the reheating furnace, subsequently descaled and rolled in the roughing stand to the transfer bar thickness and - after a second descaling step -
The temperature in the hot strip mill is only measured at a few places in the process: after the roughing mill, after the finishing mill and at the down coiler. It is only possible to measure the temperature at the surface of the strip and the temperature gradients therefore have to be calculated.
A method for controlling the temperature of a workpiece in a hot strip mill includes calculating temperature changes of the strip at each mill stand location by determining changes in workpiece deformation resistance and correlating the changes in deformation resistance to changes in temperature.
Hot Strip Mill Temperature Monitoring. We are a high-end mining machinery manufacturer in Asia. The main production equipment includes crusher, sand making machine, ball mill, Raymond mill, cement equipment and other products. Our products are widely applied in industries such as metallurgy, mines, chemical engineering, building materials ...
In a hot strip mill the workpieces are heated in a reheat furnace to a temperature of around 2200 degrees Fahrenheit (°F.). The reason the workpieces are heated to such an elevated temperature is that the temperature of the workpiece influences the resistance to deformation of the workpiece.
A technique using intrinsic thermocouples was developed to monitor the thermal response of steel samples during hot rolling. A series of hot-rolling tests was conducted with the thermocoupleinstrumented samples on CANME's pilot mill to simulate individual stands of Stelco's Lake Erie Works hot-strip mill. A mathematical model of heat transfer in the roll bite has been employed to back ...
