HBIS ShiSteel to install eco-friendly reheating furnace
Chines steelmakers are committed to
choosing green technologies for non-polluting
performance
Shijiazhuang Iron & Steel Company within
China’s HBIS Group signed a contract with
Fives for the delivery of two reheating furnaces,
each with a production capacity of
130 tons per hour. The ultimate choice was
Stein Digit@l Furnace ® due to its green performance.
This walking beam furnace,
operating on natural gas, is equipped with
patented wide flame burners and a combustion
system with individual on/off control.
The wide flame burners improve the
crosswise and lengthways temperature
profiles of the products, while the individual
on-off control allows high thermal efficiency
while reducing fuel consumption
and NO x emissions. HBIS ShiSteel is now
relocating its steelmaking facilities 80 kilometers
away from Shijiazhuang city to set
up new standards for cleaner, more flexible
and more efficient steelmaking in China.

completely executed by Fives Stein Metallurgical
Technology (Shanghai), a Fives’

First heat at Chongqing Kingsley Titanium
This project represents the first successful
commissioning of an INTECO TI-VAR
furnace in China.
The Chinese steel producer Chongqing
Kingsley Titanium Technology awarded
INTECO with the engineering and supply
of a Titan vacuum arc remelting plant
(Ti-VAR), with which ingots with an approximately
weight of 17 t and a diameter of
1,200 mm can be remelted in one melt
station. After the on schedule delivery
beginning of 2019 and the erection finalized
this spring, now and very much to the
pleasure of the client and the INTECO
expert time on site the first heat was carried
out successfully.
The remelted ingot was produced with
the so called “double-stick” method,
where one long electrode is welded out of
two smaller ones. First the stub is welded
with the consumable part and then the
second electrode is welded with the first
one in the furnace according to predefined
process parameters.
