Quenched and Tempered Reinforcement bars – IspatGuru

Quenched and Tempered Reinforcement bars The reinforcement steel bars (rebar) are produced these days by the application of the technology of quenching and tempering of the bars during its production in the rolling mill. The rebars produced by this technology are popularly known TMT (thermo-mechanically treated) reinforcement bars.

Tempcore process for the Production of TMT …

Tempcore process for the production of reinforcement bar (rebar) is a patented process in which the hot rolled bar is intensively surface quenched by water, immediately as the bar emerges from the last hot rolling stand of the rolling mill and during the subsequent air cooling the quenched outer layer is tempered by the dissipation of retained heat from the core.

01.10.2014· Rebars are “hot rolled” from steel billets and subjected to on-line thermo mechanical treatment in three successive stages : Quenching: 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 martensitic rim while the core remains hot and austenitic.

BAR AND MERCHANT BAR MILLS - SMSgroup

A water box for quenching and selftempering of the steel bars will allow the mechanical properties specifically required by the local construction industry to be achieved. The mill is complete with cooling bed and downstream finishing facilities. Among the most flexible configurations, the com-bined bar and wire rod mill using a single finish-ing block can either be operated to produce ...

What are Annealing and Quenching? - Steel Rolling Mill …

An operation in which steel is heated above a critical point or recrystallization temperature for a period of time and then slowly cooled to a cooling rate less than that in still air is called annealing. After the steel is austenitized and rapidly cooled at a rate greater than the critical cooling rate, the supercooled austenite can be transformed into martensite. This operation is called ...
