The company has formed a production scale of steel plates, steel pipes, steel profiles, and other products, with a planned layout of science, advanced Q345NQR2 hot rolled bridge steel chemistry technology and equipment, reasonable resource allocation, environmental protection, energy saving and high efficiency. BBN company has become a large-scale iron and steel enterprise integrating steel Q345NQR2 hot rolled bridge steel chemistry production, mineral resource development, steel structure and engineering construction, real estate and modern logistics.
Titanium microalloying is an element of Q345NQR2 hot rolled bridge steel chemistry strengthening complex with carbon and nitrogen. The addition of micro amount of titanium in the steel can fix almost all nitrogen and part carbon in the steel, so as to eliminate the strain aging phenomenon and improve the aging impact performance of the steel. At the same time, it can refine the grains and change the morphology of the compounds. According to the atomic weight ratio of Ti and N in Q345NQR2 hot rolled bridge steel chemistry tin formula (Ti = 3.4n), the content of Ti in steel should be controlled between 0.015 and 0.025%. Generally, the amount of ferrotitanium added to each ton of steel is 1kg.
