Quenching systems are used at hot rolling mill factories for rebar products to increase strength and hardness of production by applying pressurized water via special nozzles system. Design of quenching system can be manufactured according to needs and type of hot rolling mill. The quenching boxes of length and number of ways ( like 2 ways -3 ...

basic equipment list for tmt quench line Cooling Pipes (with built-in high pressure water spraying and specially designed wear resistant nozzles). The cooling pipes are of varying sizes and each size is for the production of a batch of bar sizes i.e. 8 to 12/16 mm, 12/16 to 25 mm, 28 to 36 mm.

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 = 1.5–4 m/sec. Water descaling unit operates according to the required rolling speed/ mill capacity. MODEL 2.

From bar mill to section mill, from chimney to complete reheating furnace, from roll stand and water quenching system to complete rolling mill train, from cooling bed area to bar/coil handling area, from flying shear to cold shear, full Automation System and from engineering services to turn-key plants ASPM is the one-stop solution for all your ...

The hot testing system consists of a water-cooled testing head, testing electronics and various software tools that together form a comprehensive, fully automated system. It can be fully integrated in the mill control network. 4.1 Water-Cooled Test Head The sensor is a robust, water-cooled test head through which the hot material passes

rolling mill, dedicated roll cooling systems are required to fulfill the required functions. Examples are suitable roll cooling and lubricationsystems to fully utilize the advantages of HSS rolls in hot strip mills, and selective roll cooling systems as a method to control the flatness of the strip in cold rolling mills.

Wire Rod Mill. weikeduo provides bar and wire rod mill systems that meet various customer needs. For example, we provide solutions to meet customer needs, such as a slit rolling system and a high-speed rolling mill (40m/s) that increase productivity, and a hot direct rolling system directly connected to the continuous caster instead of through a heating furnace, thereby …

Hot rolled bar leaving the final mill stand is rapidly quenched by a special water spray system. This hardens the surface of the bar to a depth optimized for each section through formation of martensite rim while the core remains hot and austenitic as shown in figure-4(a).

SYSTEM IDENTIFICATION: Rolling mill roll cooling water. SOLIDS/LIQUID: Mill scale, water. PROBLEM: When rolling hot steel ingots or slabs into plates, heat is transferred to the rolls, causing them to expand. At the rolling mill, cooling water is used to maintain dimensional stability of the work and backup rolls.

The rebar leaving the last stand of the hot rolling mill passes through a special water cooling section. The cooling efficiency of this installation is such that a surface layer of the bar is quenched into martensite, the core remaining austenitic. The quenching treatment is stopped when a determined thickness of martensite has been formed
