What is quenching and tempering Quenching and tempering are processes that strengthen and harden materials like steel and other iron based alloys The process of quenching or quench hardening involves heating the material and then rapidly cooling it to

Jan 06 2013 · Rebar has a medium carbon content that s nearly like high carbon so if you make a quench of dawn soap salt and water it should be a pretty good blade

You can quench in ice water and get a bit more hardness out of it than room temp water would provide even though the boiling point is the same When you quench the boiling water on the surfaces insulate the steel slightly which is why it s recommended to move the piece through the water as you re quenching it

Establishment of South Rouhina Steel Complex Iran rebar started in 2010 on a 100 hectares land in Khouzestan province located in 7 th KM Dezful – Shoushtar road Rouhina Steel consisting of two steel rolling mill and steel making factory satisfying domestic needs has the utmost potential to be one of the main exporters of steel products

BILLET The main raw material for this process is iron scrap This scrap material is tested in lab for its various elements Then the scrap is melted in electric furnaces ex 5 Ton furnace 20 Ton furnace etc The melted liquid is then poured

QUENCHING The hot rolled bar leaves the finishing mill stand at 1050° Celsius which is rapidly quenched in a water box This is a chamber where water is made to impinge on the surface of the rebar at high pressure by split style nozzle with microprocessor based controlled cooling process

Steel Rebar Production process is initiated by charging the scrap used as raw material into the electric arc furnaces The charged raw materials are turned into liquid steel by being melted down in the electric arc furnaces The steel in the liquid state is then transferred to the ladle furnaces and the necessary alloying procedures are completed in here to obtain the targeted quality
