Product Overview
Electric angle steel is mainly used to fabricate frame structures, such as towers for high-voltage transmission, frames on both sides of the main beams of steel-structured bridges, columns and booms of tower cranes on construction sites, columns and beams in workshops, etc.
Specification
Product Application
-
Double straightening + strong straightening
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.
-
Unique chemical composition design
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.
-
The development of ∠220 and ∠250 large size Angle steel
Was applied to the first ±800KV UHV direct current transmission project of "Hami-Zhengzhou" in China.
-
Energy saving and environmental protection auto production
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.
-
Research and Development
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.
-
Cooperative research and development
Cooperate with State Grid to develop low temperature resistant high strength Angle steel.
-
Automatic spray anti-rust paint
Developed anti-rust products in rainy season.
