Product Description
Electric Arc Furnace / EAF for steel making, melting and refining.
Overview
Steelmaking electric arc furnace (EAF) is divided into normal power, high power and ultra high power according to matched power.
There are left operation and right operation types for end user's option.
It could be divided into continuous charging and non-continuous charging according to loading pattern.
The electric arc furnace consists of furnace body, furnace roof (lid), tilting device, furnace lifting & rotating device, electrode lifting device, water-cooling device, hydraulic device, furnace transformer, secondary bus bar system, HV cabinet, LV electric and automatic control system etc.
Function
1. Used for scrap melting, decarbonization, dephosphorization, desulfuration, deoxygenation and molten steel heating etc., for melting steel in different grades and composition.
2. Partial hot metal charging or charging pig iron, sponge iron (DRI) and hot briquetted iron (HBI).
3. Additional charging during the melting process and primary alloying process.
Main characteristics
1. Refractory material saving due to the water cooled roof and water cooled panels.
2. Slag less tapping and tapping temperature reducing result from EBT.
3. Impendence of large current reducing due to the cooper and steel composited conductive arm and large section water cooled cable.
4. Power consumption for per ton of steel and smelting period are reduced due to adopting furnace door C-O lance and furnace wall coherent oxygen lance.
5). Fume collection rate is increased due to adopting furnace roof fourth hole and other fume discharging methods.
6). Scrap steel continuous charging and preheating system could be applied thus save energy, reduce consumption and improve smelting efficiency.
7). Raw material (DRI, HBI), lime and alloy automatic charging system could be equipped.
8). Equipped with advanced PLC control system and smelting model.
