Six main products series ( 5.0 million tons)
1. Welding Materials
2. Shipbuilding section
3. High-strength pre-stressed concrete steel bar
4. Forging ingot series
5. Steel ball series for bearing & mining industry
6. Flange & End Plate

7: Steel thick plate

 

As part of our development strategy, we have always been focused on the complete production process model. We believe this will bring us synergy effects. Therefore, recently, a new product, namely welding consumables, has been added to our catalogue. It will cover all series such as gas shielded solid welding wires, flux-cored welding wires, submerged arc wires, argon arc wires, etc., as well as medium and heavy plate series (thickness 6-800mm). Width: 1500mm-3650mm, maximum single weight: 60t

Our LT welding wire has two main advantages:
A fully integrated production process, that is, supported by the world-class upstream steel manufacturing facilities of the same group company.
The newly developed production process, which adopts the latest technologies and know-how, namely fully automatic production, will ensure quality control.
Our advantages of medium and heavy plates:
Complete electric furnaces and off-furnace refining equipment
The rated capacity of the ultra-high power electric furnace is 115 tons, and the maximum steel output per furnace is 130 tons
It has two 115-ton LF refining furnaces and one double-station VD furnace
The largest-sized steel ingots and continuous casting billets
The largest flat steel ingot is 60 tons, and the largest plum blossom steel ingot is 270 tons
The maximum single weight of the ingot steel plate: 60 tons (forged and rolled combined process)
Continuous casting adopts the techniques of dynamic light pressing, dynamic secondary cooling and heavy pressing
The maximum cross-sectional specification of the continuous casting billet is 460*2600*3600mm
Complete rolling line equipment
Advanced split vertical rolling mill

 

In the development history of Longteng Special Steel, the progress at each stage has been defined by the degree of understanding of quality. Each stage of development corresponds to the company's brand-new understanding of quality. The development and progress of Longteng Special Steel are based on an excellent quality culture.

In 2001, China officially joined the World Trade Organization. Longteng Special Steel seized the opportunity and promptly grasped the trend of the rapid development of the national economy. It vigorously developed an export-oriented economy and continuously researched and developed "specialized, refined, distinctive and innovative" products. Among them, the Marine section steel passed the certification of 9 national classification societies around the world, and the products were sold to 26 countries and regions, earning it the title of "supermarket of Marine section steel".

Longteng - Where Dreams Set Sail

"Steel is cast in fire and quenching. Only in this way can it become hard and afraid of nothing..."

"How is the steel tempered?" It is cast by our hands, our sweats, and our strong will.

While casting the steel, we are cultivating ourselves at the same time, which makes us stronger and indestructible. It is with the stiffness of the steel and fortitude like the iron that we, Longtengers, make difference again and again;

It is by virtue of the obsession with the iron and steel industry and a vision of a better future that we, Longtengers,strive in the forefront of iron and steel production;

We, Longtengers, are definitely the "steel" that is hard and afraid of nothing.

While, Longteng is the place where we train, grow and shine.

●Because we have a dream, Longteng is where dreams set sail;

●Because we love the iron and steel industry, Longteng is where we devote our life;

●Because we are the hard "steel", Longteng is where we temper ourselves.
