May 21, 2019· The company primarily produces flat rolled steel, including hot- and cold-rolled coils, heavy plates, tin-coated and tin-free sheets, and a variety of heavy sections. RH vacuum degassing plant from Primetals Technologies installed in the converter Steel Works # 2 of Altos Hornos de Mexico (AHMSA) in Monclova, Mexico
appreciate that cooling water is a vital part of the facility operation or production process; and second, that misinformation, fraudulent products, and marketing hype are common when cooling water treatment is the issue under discussion due to the proprietary nature of the water .
The life cycle of water Water management in the steel industry ... without pre- or post-treatment. It does not come into contact with the material or equipment. Fresh water is mainly used for processes and cooling. It comes into contact with the material and equipment and is treated
Our cooling tower water treatment programs are designed to provide proper chemical water treatment and preventive maintenance of open recirculating, once-through and closed recirculating cooling tower systems. | Ecolab
Jun 19, 2017· The final dimensional quality of the rolled product is determined by the rolling stands within the finishing mill. The dimensional accuracy in the final product depends on many factors including the initial stock dimensions, roll pass sequence, temperature, microstructure, roll surface quality, roll and stand stiffness and the stock/roll friction condition.
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
The cooling rate of oil is much less than water. Intermediate rates between water and oil can be obtained with a purpose formulated quenchant, a substance with an inverse solubility which therefore deposits on the object to slow the rate of cooling. Quenching can also be accomplished using inert gases, such as nitrogen and noble gasses.
The Hot Rolling Process The primary function of the Hot Strip Mill is to reheat semi-finished 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.
A high pressure water jet pump is used to remove both primary and secondary scales formed as a result of reheating of billet. It helps to improve surface quality of both hot rolled and cold drawn products. Rolling Mills Rolling mills, also known as reduction mills, are where the square billet passes through number of rollers to reduce its size ...
We understand that your productivity and product quality could be impacted by the cooling water system. Industrial cooling tower and closed loop efficiency can be adversely affected by corrosion, scaling, fouling and biological contamination. Nalco Water offers a full array of solutions including chemicals, equipment, automation and software ...
Refineries, steel mill's, petrochemical manufacturing plants, electric utilities and paper mill's rely on equipment and processes that require efficient temperature control. Mill's cooling towers, cools process water for re-use however the process water is often contaminated.
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 water-cooled copper mold.
Alongside the cold rolling mill and its auxiliary equipment, the peripheral equipment, such as the demineralized water unit, fire extinguishing system, closed cooling water circuit and air treatment systems for balanced shop air management, including preheating and heat recovery, is part of SMS group's scope of supply.
Mini Steel Mills. 343. suspended solids less than 10 g/t. For hot roll-ing, the corresponding values are 10 g/t and 50 g/t, respectively. Emissions Guidelines. Emissions levels for the design and operation of each project must be established through the en-vironmental assessment (EA) process on the ba-sis of country legislation and the ...
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 de-scaling. 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 pits.Large and medium sized mill scales

Hot-rolled is based on the slab (mainly billet) as raw material, heated by a roughing mill and finishing mill group made of steel. From finishing the last one out of the hot strip mill by laminar cooling to the set temperature, the coiling machine rolled steel strip coils, steel roll cooled through different finishing line processing and become steel, flat volume and slitting steel products.

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.
