• Quenched and Tempered Reinforcement barsIspatGuru

    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.

    5. The hot rolled Re-bars are passed through the Quenching box designed using the Tempcore process. The water temperature and the pressure are maintained by monitoring Flow temperature using PID gain controller and the use of variable frequency driven motor pumps. The quenching is done by soft water.

  • Rolling (metalworking)Wikipedia

    Hot rolling is a metalworking process that occurs above the recrystallization temperature of the material. After the grains deform during processing they recrystallize which maintains an equiaxed microstructure and prevents the metal from work hardening. The starting material is usually large pieces of metal like semi-finished casting products such as slabs blooms and

  • Boiling water quench.Heat Treating general discussion

    Jul 22 2019 · Bob good question. I would expect the hot water to be a very slow quench since you already have it to a rolling boil. It would not accept much more heat from a second source. My concern would be that the steam that is evolving in the water especially around the part being quenched would cause erratic heat removal.
