  The heated and soaked slab after discharge are descaled in a bar hydraulic descaler, and enters the reversing four-high roughing mill. The mm thick slab is Cited by: 1. Many of these old mills are still running today as a result of upgraded electrical and hydraulic systems, including hydraulic screwdowns, hydraulic roll bend, and tension control. This book does not focus on these specific rolling mill manufacturers and their various methods of manufacturing and patentability. individual components for descaling systems as well as complete descaling units for the removal of primary and secondary scale. The equipment is designed according to the latest state of the art in descaling technology using Lechler descaling software. Numerous rolling mills throughout the world have benefited from the reliability. steel making technology, basic principles of width change, plate mills, hot strip mills, quality assurance, testing and inspection, bar and rod mills. It will be a standard reference book for professionals, entrepreneurs, those studying and researching in this important area and others interested in the field of steel rolling.

High-pressure piping will be made of pipe steel, in order to connect pipe flow to the valves for descaling and complete with heavy-duty PP clamps, fittings, hoses, etc. Descaling speed on the liner = –4 m/sec. Water descaling unit operates according to the required rolling speed/ mill capacity. Rolls are tools used in rolling mills to reduce the cross section of metal stock. The weight of rolls may vary from a few kilograms up to tonnes. Under rolling conditions the contact area between roll and stock suffers wear, the other parts of a roll - body and necks - have to be considered as normal parts of designed components under high. Descaling: Audits of existing hydro-mechanical descaling systems in hot rolling mills as a method to enhance product quality Contribution paper for The Iron & Steel Technology Conference and Exposition , Charlotte N.C., USA – 05/ Jürgen FrickRead now (pdf, KB). 18 Roll Hydraulic Rolling Mill There are two types of roll hydraulic rolling mill—-Z-high type and S-high type, in which 4 sets of side support devices are added to the HC six roll mill. The rolling mill is suitable for processing stainless steel, carbon steel and non-ferrous metal strips.

  Hot strip mills use hydraulic descaling to remove oxide scales from steel strip formed after the reheat furnace and during hot rolling. In the present work, a novel analytical–artificial neural network (AANN) model was developed to improve the efficiency of high pressure (HP) hydraulic descaling operation using flat spray nozzles. soaking wascompletely removedby hydraulic descaling before rolling in low Si steel, whereasthat was not removedin high Si steel. edger to the entrance of rolling mill through a water jet descaler.   Hot rolling therefore involves the formation of mill scale (ferric oxide 2Fe 2 O 3), that has to be removed before the process is finished. In this step, which is referred to as “spray descaling”, the rolled bar passes through a descaling system prior to further forming. Some quick googling shows that a hydraulic descaler is an industrial device that uses liquid to clean scale (like limescale) from other industrial components. Some of the industrial processes using hydraulic descalers include removing scale from rolled steel in a steel mill, or the removal of caked-on gunk from oil rigs, vats, and deep fryer s.
