HXZ series DC electric arc furnace

Use: HZX series three-phase steelmaking electric arc furnaces are used to smelt carbon steel and various alloy steels, with a capacity from 0.5 tons to 100 tons.

Features

The power matching of HZX series three-phase steelmaking electric arc furnace is divided into ordinary power, high power, and higher power; according to the operation form, it is divided into left operation and right operation; the furnace cover is unscrewed top feeding type; the complete set of design is reasonable and running reliable and superior performance.

Furnace composition

Furnace body

There are two types of steel channel tapping and eccentric bottom tapping. According to the power matching, there are traditional furnace shells and tubular water-cooled furnace shells.

Furnace tilting mechanism

Electrode lifting mechanism: It can be divided into trolley mobile type and column lifting type, and its driving methods are motor driven and hydraulic driven. The electrode arm has a new fully water-cooled conductive cross arm and an ordinary copper tube cross arm.

Furnace cover lifting and rotating mechanism:

Divided into basic integral type and basic separated type.

Cooling water and its monitoring and alarm system.      

Hydraulic station and control valve system

Electrical control system:

The electrical control system adopts a new type of variable frequency speed regulation-motor type regulator or microcomputer control-hydraulic regulator. And can configure CRT display.The control and interlock protection of each part of the equipment adopt PLC control.
