Longteng Special Steel Group is a well-known private enterprise in
China's special steel industry. Founded in 1993, it is a deep
processing enterprise of metal products integrating sintering,
ironmaking, steelmaking, refining, continuous casting, rolling and
metal product processing. It has an annual output of 4.5 million
tons of various special steels and its products are sold to more
than 40 countries and regions. Longteng Special Steel Group has ten
major business segments. Its leading products include: hot-rolled
Marine sections, prestressed concrete (PC) steel bars, high-end
wear-resistant steel balls, high-end welding materials, oil and gas
pipe fittings, new energy forgings, medium and heavy plates, etc.
Among them, the three major products of Marine steel sections, PC
steel bars and wear-resistant steel balls have all become the
largest production bases in China, with market shares of over 60%
in the domestic niche industries. Among them, wear-resistant steel
balls have become the second largest supplier in the world's
grinding industry

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
Plate Flange HG/T 20592-2009 PN2.5/6/10/16/25/40 Heat Treatment
