For descaling carry out the rotation of the arms and nozzles, which neobhodimosti speed hot rolled. Rotation is transferred to the bracket using the engine and gearbox supply system liquid cooler, making installation difficult in constructive design and maintenance.
out on a Gleeble3500 Thermal Mechanical Simulation System to simulate a hot finishing strip mill. An investigation of scale growth on an assupplied surface proved that the growth of the original 21m layer of scale decreased as the steel μ oxidized further. The effects of hot rolling on the surface roughness and oxide layers such as reduction, roll speed, and entry temperature, were investigated to identify any
Sep 11, 2014· Hot rolled steel is typically cheaper than cold rolled steel due to the fact that it is often manufactured without any delays in the process, and therefore the reheating of the steel is not required (as it is with cold rolled).
Optimum roll cooling in hot and cold rolling mills. In the metalworking rolling process in hot and cold rolling mills, heat is generated by friction and deformation in the mechanical forming of the rolling stock. As a result, efficient cooling of the rolls as well as the surrounding roll area is essential for the forming process in order...
The influence of processing parameters (slab thickness, water flow of interstand cooling and oil flow in roll gap lubrication system) on the thickness and composition of the tertiary scale formed during hot strip rolling, was studied in a low carbon steel in factory. The scale formed on the rolled ...
The chemical descaler or descaling agent is a chemical or substance that we used to remove the limescale from the metal surface in contact with hot water, such as in kettles, water heaters, and boiler.

The present invention provides a descaling system for hot strip or plate mills. The descaling system includes upper and lower spray headers which are offset from each other along the pass line. Each spray header is adapted to direct a highpressure water spray on the metal product to descale the upper or lower surface thereof. The upper and lower spray headers are offset at a distance greater ...
Descaling hot rolled steel is very important, because the heat scale does not provide a very good adhesive surface for the coating. You are only missing one thing. A .
After a recent repair, a hot mill's descaling pump failed just 12 hours into operation. The hardness of the wear ring, greater than that of the impeller, caused the wear ring to act as a cutting tool slicing into the impeller shrouds and causing the impellers to break apart.
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.

May 19, 2016· Hauhinco descaling system for new rolling mill. 19 May 2016. Hauhinco, an intelligent hydraulic water solutions company with operations in Evans City, Pennsylvania, has been contracted by a customer to engineer a descaling system for a new rolling mill for stainless steel panels.
Mar 31, 2007· Thread: Removing Scale on hot rolled angle iron. It is 4x6x3/8 steel angle that has to be powder sent out a sample to be powder coated with out grinding but did not turn out like we have many pieces to grind after they have been welded. These are display cases 32"x48" top and bottom with 2x2 steel tube between making them 72"...
High Pressure Descaling before the Finishing Mill. For wear reduction and better water drain inside the descaler box we received the order to modernize the descaling unit on the entry side of the finishing mill. We reused the existing rotating descaling system.
Descale valves are designed to operate with raw water, reprocessed water, and recycled water fluids. Our new ceramic technology allows for a ceramic controlled pilot circuit, alongside hardened stainless steel internals including stainless steel seats.
Designing a plate mill is far more than an exercise in mechanical engineering. It is a special and unique example of combining operational efficiency and metallurgical function. Plate products derive their properties from the deformation and temperature path they follow, and this means that the flexibility to roll a broad mix in a single mill must be built into the layout and the machine parameters.
