Electric angle steel

Double straightening + strong straightening is becoming perfect to ensure that the straightness accuracy of each Marine section steel is less than 1‰， reaching the international advanced level.

At one stroke, the yield strength of high-strength large-size Angle steel is easy to be low, and the steel has good impact toughness.

Was applied to the first ±800KV UHV direct current transmission project of "Hami-Zhengzhou" in China.

The automatic production line is composed of online automatic straightening and rust removal, cold drawing and score, online heating by high-frequency induction heating furnace (secondary quenching heating and primary tempering heating), automatic control of cooling water temperature of heat treatment, water through heat treatment, online rust prevention treatment of finished products and SVG harmonic elimination + reactive power compensation and other advanced technology and equipment. Realize the mode of energy saving and environmental protection automatic production; At the same time, ensure the product quality to reach the domestic advanced level.

Customers have a large pipe diameter in the production of sea piles, generally 800-1200mm, and the largest one even reaches 1500mm. Therefore, when customers choose prestressed steel rods, they require steel rods to reach 14mm or above. Through the full cooperation of all departments of the branch, samples have been produced for customer trial.

Cooperate with State Grid to develop low temperature resistant high strength Angle steel.

Developed anti-rust products in rainy season.
