Equipment Technology of Used Electric Arc Furnace for Sales in India
Overview
5t three-phase used electric arc furnace for sale in India, the structure of the used electric arc steelmaking furnace adopts the furnace cover to remove the top charging, the tapping nozzle taps, and the right or left operation is selected by the user. Electrode lifting is mechanical, furnace body tilting and furnace cover lifting and rotation are hydraulic, and electrical control is controlled by PLC (Siemens) regulator.
Main features of the used electric arc furnace for sale in India:
This steelmaking used electric arc furnace for sale in India can use alkaline or acid lining as required and can melt carbon steel, high-quality carbon steel, alloy steel, stainless steel, and other varieties. This electric arc furnace equipment has the following main features:
- The electric furnace equipment is the furnace cover unscrewing, top charging, tapping nozzle, and semi-elevated arrangement.
- Using copper-steel composite conductive cross-arm, the whole is a column type.
- Using large-section water-cooled cables.
- Using the whole furnace shell, the structure is firm and the rigidity is good.
- Using water-cooled furnace cover structure, long service life.
- The most advanced intelligent PLC electrode regulator is adopted to ensure the accuracy and reliability of the electrode automatic system to the greatest extent.
