Sep 08, 2017· Several types of descaling processes are used for removal of scale from the surface of the hot rolled steels. These descaling processes are usually classified into four categories. These are (i) flame cleaning process, (ii) mechanical descaling processes, (iii) hydraulic descaling process, and (iv) chemical descaling processes.

primary descaler in hot strip mill

Regarding hot rolling of steel, the quality of the rolled metal surfaces depends to a large extent on effective descaling. In order to avoid surface damage, iron oxide scale layers are therefore removed from the hot steel surface by high-pressure water spraying prior to the actual hot rolling process.

In part because further descaling is not particularly practical once finish rolling begins, the #2 Scale Breaker is the last opportunity to remove oxidation before the finished hot-rolled strip is coiled. Typically, the descaling system in the Hot Strip Mill is very effective at removing primary (from the furnace) and secondary (regrown

Mechanical descaling | Wheelabrator

Running the descaler pump at constant speed wastes energy and water, and heavy maintenance is required on the motor, bypass valves, and the pump. Control system tests in a steel mill using a variable speed pump showed annual electrical savings of 1,320 MWh/year. With an electricity cost of $0.10 per kWh, the savings are $132,000 per year.

descaling system for hot rolling mill

The temperature of the hot melt is reduced by means of a chilled roll. The melt is cooled down very quickly, with possible flow rates of up to 100 kg/h. After cooling, the product is reduced to flakes by means of a kibbler. The subsequent milling procedure can be done on line by directly adding a hammer mill or a conical mill.
