How Should Carbon Electrodes, Graphite Electrodes And Self-Baked Electrodes Be Used CorrectlyⅡ?

Self-baking electrode uses anthracite, coke and asphalt and tar as raw materials to make electrode paste at a certain temperature, and then put the electrode paste into the electrode shell installed on the electric furnace. In the production process of the electric furnace, it relies on the Joule heat generated when the current passes through and the conduction heat in the furnace to sinter and coke on its own. This kind of electrode can be used continuously, and the long side is used to form the junction, and it can be baked into a large diameter. Self-baking electrodes are not only simple in process and low in cost, so they are widely used in the production of ferroalloys. Graphite electrode joint manufacturer shares with you.

The main technical performance of the electrode

The electrode material should have the following physical and chemical properties:

① The conductivity is better, the resistivity should be smaller, to reduce the loss of electrical energy, reduce the voltage drop of the short network, and increase the effective voltage to increase the power of the molten pool;

② The melting point should be high;

③The coefficient of thermal expansion should be small, when the temperature changes rapidly, it is not easy to deform, and small cracks cannot be generated due to the internal stress brought by the temperature change to increase the resistance;

④ Sufficient mechanical strength at high temperature;

⑤ Impurities should be low, and the impurities should not pollute the smelted varieties.

Selection of electrodes in ferroalloy industry

Self-baking electrodes are widely used in ferroalloy smelting, refining ferrosilicon, silicon chromium alloy, manganese silicon alloy, high carbon ferromanganese, high carbon ferrochromium, medium and low carbon ferromanganese, medium and low carbon ferrochromium, calcium silicon alloy, ferro tungsten Wait. Self-baking electrode is easy to increase the carbon production alloy, iron belt into carbon, production of iron alloy and pure metal with very low carbon content, if carbon ferrochrome, industrial silicon and metal manganese should use carbon electrode or graphite electrode.
