were awarded the first prize of Jiangsu provincial scientific and
technological advancement award, second prize of national scientific
and technological advancement award, and won national invention patent.
These technologies have been widely popularized in China＊s metallurgical
Huaigang continues to strengthen R & D capabilities,
and there is a strong R & D team and institution. Approved by
the State Ministry of Personnel, Huaigang became the national post-doctoral
scientific research workstation. With approved from Jiangsu Department
of Personnel and Economic & Trade Commission, Huaigang is the
first company to set up Post-doctoral Technological Innovation Center
among metallurgical companies in Jiangsu, and together with Central
Iron & Steel Research Institute Huaigang Past-doctorial workstation
was established. At the mean time, Huaigang works closely with Northeastern
University and Jiangsu University so that Huaigang become a teaching

4. Recycling, Energy Saving and Consumption
To promote energy saving and emission reduction,
and achieve cost lowering and efficiency improving, Huaigang is committed
to reform traditional growth pattern of ※mass production, mass consumption,
mass emission, mass pollution§, actively develop recycling economy
and has achieved high efficient utilization of resources and energy.
Wastes are utilized and changed into valuables.
Huaigang uses sintering as an important process to recycle iron bearing
solid metallurgical wastes. Precipitator dusts from EAF, BOF, Blast
Furnaces and Sintering Machine, oxide scales from rolling, BOF and
EAF slag with iron content up to some certain percentage are all reclaimed
for sintering production, by which dust pollution is reduced, and
also iron bearing solid metallurgical wastes are effectively utilized.
International advanced harmless processing method
was adopted for blast furnace slag. Ultra fine slag powder produced
from blast furnace slag was directly mixed into cement. The mixing
ratio is up to 40% and concrete strength is increased by 30%. Consequently,
consumption of mineral resources for cement production and emission
of harmful gases are reduced and production cost of construction industry
Tailings separated magnetically from BOF and EAF slag
are used for sidewalk encaustic brick manufacturing, machine-made
bricks for construction, construction backfill and so on, resulting
in zero emissions of solid wastes.
Recycling of secondary energies. Currently BOF
gas, blast furnace gas and coke oven gas can be fully recycled at
Huaigang. BOF gas and steam recovered reached 110 m3, 80 kg per ton
steel respectively, and steelmaking with minus energy consumption
has been achieved.
Recycling of blast furnace gas, coke oven gas and
BOF gas. 36,000 tons of coal are saved annually by substituting coal
for gas, using coke oven gas for pellets producing, closing the coal
gas generator of pellet plant. BOF gas is also used for lime production.
At present, BOF gas recovered at Huaigang can not only meet the demand
of two sleeve lime kilns which produce more than 800 tons of lime
daily, but also some of the remaining BOF gas goes back to BOF workshop
for ladle heating. Substituting oil for gas, rolling plants utilize
low calorific blast furnace gas for billet heating in stead of heavy
oil and have achieved oil free reheating in rolling plants, thus save
about 100,000 tons of heavy oil consumption. By heating ladles and
tundishes with coke oven gas in both BOF and EAF meltshop, the company
saves more than 6500 tons of diesel annually.
Recycling of stream. Steam recovered from BOF is
used for the heating of operation rooms, lounges and offices during
winter time, replacing electric heating and air conditioning, thus
2.6 million kWh of electricity are saved annually. In May 2008, during
the major overhaul of EAF, Huaigang carried out energy saving retrofit
of EAF dedusting system - EAF residual heat recovery using heat pipe
technology. Through this retrofit, 17 tons of steam are recovered
hourly, resulting in more than 10,000 tons of standard coal saving
annually. Thus EAF dedusting with minus energy consumption was realized.
Recycling of coking byproducts. All byproducts
during coke making are recycled. Coke tars are used in Rolling Plant
No.1 to make up for the lack of coke oven gas. Benzene, naphthalene,
and thiamine are recovered as production raw materials for chemical
enterprises. Coking fumes are desulfurized to reduce air pollution
and promote cleaner production of the company.
Orderly recirculating of water and adopting ※dry§
process instead of ※wet§ process. Huaigang has always carried out
the water utilization program of ※classified supply and resuing, staged
treatment§ combined with ※orderly recirculating utilization§.
Huaigang＊s comprehensive energy consumption per
ton steel continued to maintain top 10 among key metallurgical enterprises
in the country and ranks top 5 among similar companies. Recirculating
rate of water is above 97% and fresh water consumption per ton steel
is less than 3.6 tons, which maintain national advanced level in metallurgical
In the last years of the ※11th Five Year Plan§,
Huaigang will focus on the expansion of industrial chain backed by
3 million tons of special steel. Huaigang＊s goal is to realize 30
billion RMB sales revenue at the early stage of the ※12th Five Year
Plan§ while strive to reach 50 Billion RMB, and become China＊s modern
large-scale special steel company.
