It is understood , HRB400E test seismic reinforcement steel is rolling

Tonghua Iron and Steel Group has successfully developed high-speed wire production HRB400E
November 21 , Tonghua Iron and Steel Group, Shougang Tonghua Steel new line of high-speed wire rod plant produced a total HRB400E8 mm rebar 42 99.7 tons , HRB400E8 mm rebar development and production won success.
It is understood , HRB400E test seismic reinforcement steel is rolling temperature requirements are  very strict , is a newly developed product is currently being pilot production   phase. The production is the fourth year the plant rolling, rolling is the largest number of the best one , spinning temperature for the first time dropped to 900 ℃, changing the spinning temperature is not lower than the previous record of 1000 ℃ .
In the production process of organizing high precision bearing , the plant production department and rolling rolling workshop related personnel to develop a reasonable program , repeatedly revised operating points , follow the guidance and technical personnel on-site , requiring workers reasonably controlled roller speed, to ensure open rolling Wind turbine bearing temperature , temperature and spinning into the finishing temperature , to strengthen the mill grooves , guide and guard the entrance examination , timely adjustment of the finished wire size , seismic steel products to ensure customers' dimensional accuracy requirements to ensure the quality of pruning to ensure end to end water cooling and defective parts are not all clean and trim so storage product quality to meet market and customer needs.
It is reported that the feedback from the technical center sampling data, the indicators uniformity , yield strength and tensile strength to meet quality requirements.
