Power Generation Applications-Market-Longteng Special Steel Group

Industry Overview

Wind energy is one of the pollution-free energy sources, as a clean renewable energy, get more and more attention from all countries in the world.

Wind power has the advantages of clean, good environmental benefits, renewable, short infrastructure cycle and flexible installed scale. Wind power is an essential part of renewable energy development, an important force to promote energy technology progress and industrial upgrading, and an important measure to promote energy structure adjustment. China's wind power and other new energy power generation industries have very broad development prospects and are expected to maintain rapid development for a long time in the future.

Product Application

Wind power generation uses wind to drive the windmill blades to rotate, and then uses a speed increaser to increase the rotation speed to prompt the generator to generate electricity. Slewing bearing is a new type of mechanical component that is gradually emerging around the world. It consists of inner and outer rings, rolling elements, etc., and is an important structure of wind turbines. Bearing steel ball products are used as rolling elements in yaw bearings of wind turbines and large slewing bearings of pitch bearings.

Welding Materials

Our welding materials products consist of three major series: solid welding wires, flux-cored welding wires, and welding electrodes, with over 200 varieties in total. In addition to their conventional applications, our products are also evolving towards specialized welding materials for high-strength steel, heat-resistant steel, stainless steel, and non-ferrous metals. These welding materials are widely used in various industries, including steel structure construction, shipbuilding, pressure vessels, oil pipelines, rail transit, marine engineering, and nuclear power.

Bearing steel ball

Bearing steel balls are very important basic component. Where is rotation, Where are bearing balls. We have the annual production capacity of 30,000 tons of various types of bearing steel rolling element blanks. Our products are widely used in metallurgical mining machines, mechanical bearings, engineering machinery slewing bearings, motor bearings, wind power equipment yaw and pitch bearings, automobile parts and other fields.
