AE series preheating continuous feeding equipment is the mostadvanced, clean, energy saving and environmental protection metallurgyoff gas using equipment in nowadays. This is using the off gas fromtheelectric furnace to preheat the raw materials, and avoided the highfailurerate, complicated operation, can not charging materialscontinuously and etcweakness from Shaft furnace preheating andpreheating bucket and etctraditional ways.This system has beenputinto production in more than 20 factories in china and several othercountries.And had gain marked affectsin electricity saving, energysaving, production increasing, pollutionreduction, and brings greateconomic benefits for customers.
AE series preheatingcontinuous feeding equipmenthas characteristics of continuous feeding, continuous melting,continuoussmelting and etc… which's advantages are: smelting period isshort, low powerconsumption, low noises, low investment cost and etc…
Compare with the traditional EAF, the technical index of continuouslypreheating and feeding EAF process are:
- Productioncapacity increases more than 10%.
- Smeltingcycle is shortened by 10-15 Min.
- Save energyof 100-120kw.h/t for per ton Steel.
- Electrodeconsumption decreases by 0.5-0.8%, Refractory material consumption reduces by5%.
- 20-30% reduction of CO2 volumewhich is released fromper ton of Steel; Production sitedustiness lessthan 10mg/M.
- Dioxin and CO emissions meets relative emission standards,smoke and dust is decreased from 17kg/tto 11kg/t.
- Fully utilization of waste heat: On the Conveyor section canpreheat the materials up to 300degree Celsius and higher, and addburner in conveyor section, can raise thematerials up to 600 degreeCelsius. The rear part of the waste heat can be usedto generateelectricity or heating by steam which is producedby waste heat boiler,thegas from the boiler basically can go into the bag type dustcollectordirectly.But the traditional electricfurnace system offgas must go through the water cooled pipes, air forcedcooler and etcequipments, it will consumable much energy to cool thetemperature downand then can put the gas go into dust collector, so waste theenergyfrom the off gas.
- De-dusterFan power reduces 30%.
- Noise isfewer than 90 decibels during the electric furnace smelting cycle.
With fullyconsidering for customers kinds ofactual using status, AE series preheatingcontinuous feeding equipmentbrings direct economic benefitsto customers by lowest failure rate,highest energy saving index, biggestinvestment return.
