AE series preheating continuous feeding equipment is the most
advanced, clean, energy saving and environmental protection
metallurgy off gas using equipment in nowadays. This is using the
off gas from the electric furnace to preheat the raw materials, and
avoided the high failure rate, complicated operation, can not
charging materials continuously and etc weakness from Shaft furnace
preheating and preheating bucket and etc traditional ways. This
system has been put into production in more than 20 factories in
china and several other countries. And had gain marked affects in
electricity saving, energy saving, production increasing, pollution
reduction, and brings great economic benefits for customers.
AE series preheating continuous feeding equipment hascharacteristics of continuous feeding, continuous melting,
continuous smelting and etc… which’s advantages are: smelting
period is short, low power consumption, low noises, low investment
cost and etc…
Compare with the traditional EAF, the technical index of
continuously preheating and feeding EAF process are:
lProduction capacity increases more than 10%.
lSmelting cycle is shortened by 10-15 Min.
lSave energy of 100-120kw.h/t for per ton Steel.
lElectrode consumption decreases by 0.5-0.8%, Refractory material
consumption reduces by 5%.
l20-30% reduction of CO2 volume which is releasedfrom per ton of Steel;Production site dustinessless than10mg/M.
lDioxin and CO emissions meets relative emission standards, smoke
and dust is decreased from 17kg/t to 11kg/t.
lFully utilization of waste heat: On the Conveyor section can
preheat the materials up to 300 degree Celsius and higher, and add
burner in conveyor section, can raise the materials up to 600
degree Celsius. The rear part of the waste heat can be used to
generate electricity or heating bysteamwhich is produced bywaste heat boiler, the gas from the boiler basically can go into the bag type dust
collector directly. But the traditional electric furnace system off
gas must go through the water cooled pipes, air forced cooler and
etc equipments, it will consumable much energy to cool the
temperature down and then can put the gas go into dust collector,
so waste the energy from the off gas.
lDe-duster Fan power reduces 30%.
lNoise is fewer than 90 decibels during the electric furnace
With fully considering for customers kinds of actual using status,
AE series preheating continuous feeding equipment brings directeconomic benefits to customers by lowest failure rate, highest
energy saving index, biggest investment return.
