Jul 20, 2015#0183;#32;The guide features a robust fabricated steel body with replaceable wear plates and incorporates single symmetrical adjustment of guide rolls. The guides are constructed either with two roller holders and a spacer piece or with four individual holders one for each rollers. The guides also have a feature of independent direct lubrication and water cooling feeds for ensuring maximum service life
Nov 27, 2015#0183;#32;Two half circle water pipes for each roll also deliver secondary cooling water to assure the heat of rolling does not penetrate the roll body. The application of cooling water is to be controlled so that the water does not fall on the rolling stock at the entry point to the rolls. In case it happens, it only cool the rolling stock, create steam pockets between the roll and the rolling stock, and waste water that could

For roll cooling applications of hot steel pure water is normally used as a coolant. The water is usually recirculated in the plant and should have a sufficient filtration grade in order to prevent clogging of the nozzles. The maximum particle size shouldnot exceed 1/3 of the smallest nozzle internal passage.
P. Kucsera et al. Hot Rolling Mill HGC Thickness Control Improvement 98 Another way to determine the thermal expansion of the work roll is the modelling of the heat transfer between the work rolls and the strip. This depends on the roll speed, strip thickness, the properties of the strip, roll gap, contact time and cooling parameters.
Coolant is used for multiple reasons: 1) to cool rolls; 2) to provide lubrication (in cold mills); 3) to control product temperatures (for example in interstand cooling stations in hot mills); and 4) to control the thermal profile (in most cold sheet mills, many other cold mills, and increasingly even in hot mills).

Dec 03, 2015#0183;#32;The interstand facilities are vitally important for the production of hot rolled strip with top surface quality. Important equipment includes (i) entry and exit guides, (ii) work roll cooling system, (iii) anti peeling device, (iv) roll gap lubrication system, and (v) interstand cooling and descaling systems.
These rolls can either be flat or grooved (contoured) for the hot rolling of rods or shapes. Under these conditions, the rolls grip the piece of metal and deliver it, reduced in crosssectional area and therefore, increased in length. x The initial hotworking operation for most steel products is done on the primary roughing mill
They want the rollers to stay below 40#176;C to prevent the algae material being oxidized. And we had to turn on the cooling system, which can maintain the roller temperature #177;23#176;C around ambient temperature. It is very common for rollers to get warm after a prolonged period of continuous running.
Each heavyplate mill features its own individual layout. That depends on the product mix, the product geometries, and the installation site. Common to all mills are the main process sections: reheating furnaces, mill area with one or two reversing 4high stands, plate cooling and hot plate leveler, cooling beds, shearing line, finishing line, heavy plate line, and heat treatment line.

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.
