• 30 MT/12.5 MW induction furnace of 2 Nos.  25 MVA with production of 960-1000 MT per day in practical.
• 35 MT LRF can be used.
• Power consumption will be 525 Kwh/ MT. No Oxygen lancing is required.
• Being Static load power factor remains 0.94 to 0.97
• MDI demand 40% less compared to arc furnace for same production.
• Being study load no consideration of fault level
• No problem for any connection. Power station are enough capacity for induction furnace
• Induction load is steady and without any fluctuation.
• Due to 12 pulse harmonics distortion level will be comparatively very low. Small capacity of harmonics filter may require. Even need not for Harmonic filters.
• In Induction furnace no electrode is used

• For 60 tonne electric arc furnace require 40 MVA with production of 840-900 MT per day in practical.
• 70 MT LRF is required.
• Power consumption will be minimum 600 Kwh / MT plus 20 Oxygen / Ton
• Power factor will vary from 0.75 to 0.80 and to be increased by capacitor bank to 0.92 at extra cost.
• MDI demand will be 1.5 than Induction furnace as compared to production.
• The fault level in Arc furnace will be around minimum 50 times means power substation should be of 2000 MVA capacity
• Generally Saudi Arabia power station are not strong to provide connection for more than 20 MVA arc furnace due to fault level
• There is to too much flickering, power fluctuation affecting the substation and power lines.
• In arc furnace the harmonics level is high and not acceptable to electricity board and you have to provide harmonics filter
• Electrode consumption in arc furnace is around 4 Kg per MT costing around US$15 per tonne

PRODUCTION

• Production will be around 960-1000 MT per day

• Production will be around 840-900 MT per day

REFRACTORY

• Acidic ramming mass (Silica quartz) is used and the per tonne cost is 1/4 of arc furnace

• High Alumina and Magnesite ramming mass and bricks are used in lining

• If similar scrap is used burning loss is not more than 5% to 6 %

• In arc furnace burning loss is 10 %

• Ferro Alloy consumption is about 70% due to calculated charge mixes compare to arc furnace.

• Due to slag making technology and oxidation Ferro alloys consumption is high.

• Oxygen lancing is not required

• In arc furnace oxygen gas lancing is must.

• We can manufacture all types of alloy comparable to arc furnace. There is no problem for any alloys. Alloy steel can be manufactured with calculated charge and with help of LRF.

• Alloy steels can be manufactured to micro control to chemical composition

• Maintenance is around 30% as compared to arc furnace due to non moving parts and electronics base.

• Maintenance cost in arc furnace is very high, minimum 3 times than induction furnace due to too much mechanical and electrical system

• In induction furnace a few skilled technical personnel is required.

• In arc furnace skilled people’s team of mechanical, electrical & metallurgical is required. Costing double than induction

• Labour cost is low as 70% of arc furnace

• Labour cost is high

• Induction furnace is a compact furnace and required about half area as compare to arc furnace.

• In arc furnace three times area is required due to high volume and area of the furnace as induction furnace

• 35 MT LRF is required for minor composition adjustment.

• 70 MT LRF is must for arc furnace for composition control.

• In case of induction furnace capital investment will be around 50% of arc furnace

• Capital investment required in arc furnace is 3 times the induction furnace due to high cost of plant and machinery infrastructure cost, area requirements.
