25500kVA Industrial Silicon Submerged Arc Furnace

1, Production process description

According to the actual production situation of industrial silicon electric furnace with capacity above 25500kva in China, it is suggested that the whole coal smelting process should be selected as the smelting process.

1.Principle of industrial silicon production

In the submerged arc furnace, using the heat energy converted by electric energy, silica and carbonaceous reductant react to produce industrial silicon.The reaction process is relatively complex, which can be simply expressed as SiO2 + 2C = Si + 2CO

Applications

HXZ series steelmaking DC arc furnaces are used for melting quality carbon steel and kinds of alloy steel. Their

normal capacities are from 3t to 100t.

Features

According to its power matching, HXZ series steelmaking DC arc furnaces can be divided into OP, HP and UHP;

According to its operation form, it can be divided into left and right operations. The type of roof is a kind of

spinning to add material. The whole apparatus is of a reasonable design, reliable operation and excellent

performance.

Description

· Furnace body

Tapping manners: Spout and EBT

Tubular water-cooled and traditional roof are available

· Tilting mechanism

· Electrode lifting mechanism

It can be realized by bogie movement lifting. And common copper tube arm or advanced water-cooled

conducting arm are available.

· Roof lifting mechanism

Integrated or separated foundation designs for your choice.

· Cooling-water monitoring and alarming system

· Hydraulic station and control valves system.

· Electric control system:

Automatic regulator of electrode lifting can be VVVF controlled or computer controlled. The later can equipped

with CRT displayer. The acting of all parts and interlooks is controlled by PLC.

Most advanced technologies of steelmaking arc furnace can be provided as request:

· Single-electrode D. C powering technology

· 50% less electrode consumption
