November 21 , Shougang Tonghua Iron and Steel Group through high-speed wire rod plant new lines of production HRB400E8 mm rebar 42 99.7 tons , HRB400E8 mm rebar awarded the successful development and production .
It is understood , HRB400E test  seismic reinforcement steel is rolling temperature requirements are very strict, new product development is currently under trial production stage. The production is the fourth rolling plant this year, but also the largest number of rolling , the best one, spinning temperature first drops 900 ℃, changing the spinning temperature is not lower than the previous record of 1000 ℃ for .
In the organization of production vibration measurement process, production department and rolling mill plant personnel to develop a reasonable plan rolled repeatedly revised operating points , the technical personnel at the scene to track the guidance requires workers reasonable control roller speed to ensure open rolling temperature , temperature and spinning into the finishing temperature , strengthen inspection high precision bearing of rolling groove , guide and guard the entrance , timely adjust the size of the finished wire , seismic steel products to ensure customer requirements for dimensional accuracy , quality assurance 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 data center sampling technique from watching the indicators uniformity , yield strength and tensile strength are up to quality requirements.
