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.

Water Requirements of the Iron and Steel Industry By FAULKNER B. WALLING and LOUIS E. OTTS, JR. ... Water use in the iron and steel industry varied widely and depended on the ... try generally considers all water used in rolling mills as cooling water, it is reported as such in this report. Intake water is water added to a
Continuous Caster Cooling Water Continuous Caster – Water Recycle. Since the 1960s, continuous casting has become increasingly important in modern steel production. Today more than 80% of the worldwide production uses this process. Liquid steel flows out of the ladle into the tundish, and then into a watercooled copper mold.

Steel Steel Treating of steel: In principle, heattreating already takes place when steel is hotrolled at a particular temperature and cooled afterward at a certain rate, but there are also many heattreating process facilities specifically designed to produce particular microstructures and properties.
Cooling Tower Bypasses. Cooling tower bypasses are generally specified for towers installed in cold climates. The bypass is used to prevent overcooling of the water when there is little or no heatload in the system. The bypass should discharge into the tower basin as far as possible from the cooling water .

The steel industry has historically presented challenges for effective water treatment because it is a high water user and the applications may involve high heat, critical noncontact cooling, direct contact cooling, high suspended solids waters, oil and grease contamination, and complicated cascading.
The Oxelösund plant''s recycling process operates by collecting both the cooling water and the slag formed on the surface of steel by the roller cooling in a basin under the rolling mill. This basin empties by gravity to a large sump, which receives about 1,000 m3 per hour of the slurry formed by the cooling water and slag particles.
EPA promulgated the Iron and Steel (IS) Effluent Guidelines and Standards (40 CFR Part 420) in 1974, and amended the regulation in 1976, 1982, 1984, 2002 and 2005. The regulation covers any facility that is engaged in iron or steel manufacturing, forming, and finishing, including coke manufacturing.
Nordic Water''s preferred solution is a large screw dewaterer. This is basically a settling tank where the material settles out, and a screw conveyor removes and dewaters the settled scale. Although used for many years in mineral treatment, application in steel mills is fairly recent.

and noncontact cooling water is also sent to the Final Treat. Wastewaters entering the Final Treatment Plant are treated through this system to adjust pH, remove solids and remove any remaining oil. The effluent from this facility is discharged through NPDES Internal Outfall 104 and ultimately through NPDES Outfall 004 into Burns Waterway.
Jul 13, 2015· Another use of process water is for pickling, cleaning, and coating operations in the cold rolling mills. The major use of water in the steel plant is for the purpose of cooling. Cooling water is generally classified as either noncontact or indirect cooling water and contact or direct cooling water.
by the city as part of their water treatment program, while the majority of the phosphate was due to the treatment of the system. BACKGROUND A mini mill customer was experiencing severe scaling of their cooling tower, which was critical for continuous casting contact cooling. The system uses city water as makeup source for the cooling tower.
This conference will bring stampers and die shops up to date on new lubricants for stamping and tool and die machining, and help them evaluate new formulations and select the right lubricant for the job.
Direct Cooling Water Circuits In the hot strip mill, high pressure water is sprayed on the hot rolled plates/coils as they move on the turnout table for descaling. Water is also sprayed to cool the rollers and bearings .The hot return water, laden with mill scale and lubricating oil, is drained into scale and medium sized mill scales
