Ultra high frequency furnace front to cater to the ribbed bar better quality
In 2013?October,?the superior?sent a?notice,?notice as follows:
1?reinforcement application technology?specification?to actively promote the?high strength steel,?which provides technical support for the?comprehensive?application of 400Mpa,?500Mpa grade steel,?and in some?range?(beam,?columnlongitudinal stress?reinforced)?in?the elimination of HRB335steel.?Iron and steel enterprises should?advance?equipment modification?and technical reserves?400Mpa,?500Mpa grade steel?production,?good?production HRB335?reinforcedpreparations.
2 HPB235?steel?is no longer?used,?and?used HPB300 steel,the?application of?departments and enterprises?should be prepared to.?Future?of Q235 wire rod?construction?directlyapplication?(but?less?traffic,?railway,?hydraulicengineering?temporarily?also?application),?the minimum diameter?of HPB300 reinforced bar?should be 6MM,?production units?and the use of?units are not?adhere to the?6.5mm?do not put.
3 in the?application of HPB300 reinforcement?of the transition period,?the production units and?the use of?units should be?used?for small diameter,?high strength steel?tomake the transition.
4 strengthen quality?deviation control,?avoid?negative deviation?exceed the standard?of reinforced?approach,resulting in adverse?impact?and economic loss.
So far,?the new high frequency?furnace /?Henan Chao?Feng electrical?introduction of?high frequency induction
heating equipment.?The?annealing?ribbed bar?were studied.?The success of the?experiment?the?heating method?can make the best?of the cold-rolled ribbed bars!
