Working principle:
Using the high temperature generated by electrode arc to melt
special alloys, electrical energy is input into the furnace through
graphite electrodes or other special electrodes. An arc is formed
between the electrode end and the furnace material, converting the
electrical energy into heat energy to melt the special alloy raw
materials in the furnace and complete the high-temperature
metallurgical reaction.
Structure Design:
Furnace body: It is often made of all stainless steel material, such as square
or vertical cylindrical structures, with double-layer water-cooled
walls, which can effectively cool down, prevent corrosion, extend
the life of the furnace body, and maintain a stable working
environment.
Electrode system: Water cooled electrodes, such as tungsten or graphite electrodes,
are usually used, which can move 360 degrees and adjust their
position flexibly to meet different melting needs, with less
electrode consumption during melting.
Vacuum system: Equipped with a high vacuum system consisting of mechanical pumps,
diffusion pumps, or molecular pumps, it can achieve high vacuum
inside the furnace and meet the requirements of special alloys for
melting environment.
Observation and control device: equipped with a large aperture observation window for real-time
observation of the furnace situation, and also equipped with an
operation simulation screen for intuitive display of control data,
achieving PC/PLC fully automatic control and manual touch screen
control.
Performance characteristics:
High temperature melting capability: capable of producing temperatures above 3000 ℃, meeting the
melting needs of high melting point special alloys such as tungsten
molybdenum palladium iridium.
Accurate temperature control: It can precisely control the furnace temperature, ensuring the
stability and uniformity of temperature during the melting process
of special alloys, and ensuring the consistency of alloy
composition and properties.
Flexible atmosphere control: By adjusting the atmosphere inside the furnace, such as vacuum,
inert gas protection, etc., it is possible to prevent easily
oxidizable elements in special alloys from being oxidized and
improve alloy quality.
High melting efficiency: The arc discharge directly acts on the furnace charge, resulting
in high energy conversion efficiency. It can complete the melting
of special alloys in a short period of time, improving production
efficiency.
Technical Parameter:
The parameters of special alloy electric arc furnaces of different
models and specifications vary, including electric furnace
capacity, transformer capacity, electrode diameter, smelting
temperature range, vacuum degree, cooling water flow rate, and
pressure.
