Application of self-baking electrodes in smelting brown corundum and black corundum
As an important form of electrode, self-baking electrode has shown its unique advantages and wide application prospects in the smelting of brown corundum and black corundum.This article will discuss in detail the application of self-baking electrodes in the smelting of brown corundum and black corundum from the basic principles, application advantages, technical details and economic benefits of self-baking electrodes.
The basic principle of self-baking electrode
The self-roasting electrode uses the heat of the furnace mouth surface and the melt in the furnace to roasting the electrode cylinder and electrode paste, so that it gradually softens and sinters to harden, and then has a certain mechanical strength and electrical conductivity.The preparation process of this electrode is simple, the cost is relatively low, and it can be used continuously, and it can be sintered and formed while using the long side.Its main raw materials include anthracite coal, coke, asphalt and tar. These raw materials are mixed at a certain temperature to make an electrode paste, and then loaded into the electrode shell that has been installed on the electric furnace.
Application advantages of self-baking electrodes in the smelting of brown corundum and black corundum
Solve the problem of tight electrode supply
Smelting brown corundum and black corundum with self-baking electrodes can effectively solve the difficulty of tight supply of forming electrodes.The production cycle of traditional molded electrodes is long and the cost is high, while self-baking electrodes can be prepared on site, which has strong flexibility and greatly improves production efficiency and stability.
Improve economic efficiency
The use of self-baking electrodes can significantly reduce the cost of brown corundum and black corundum abrasives.According to relevant data, under normal continuous working conditions, the self-baking electrode consumes 1kWh of electrical energy per kilogram of electrode paste, which is much lower than the energy consumption of traditional electrodes.In addition, the cost of raw materials for the preparation of self-baking electrodes is relatively low, further reducing the overall production cost.
Waste heat utilization and energy saving
During the smelting process, the heat loss of the flue gas of the smelting furnace is large, usually more than 15%.The self-roasting electrode can use this part of the waste heat for the roasting of the electrode, which realizes the efficient use of energy, improves the energy utilization efficiency, and reduces the energy consumption cost.
Technical details
Smelting equipment structure
For the smelting of brown corundum and black corundum, the use of self-baking electrodes needs to be combined with specific smelting equipment.For example, a self-roasting electrode dumping furnace structure suitable for brown corundum smelting includes a dumping furnace cylinder, furnace cover, electrode load-bearing steel platform, electrode hole, sheath, copper tile, conductive copper tube and other components.The structure is reasonably set up and easy to operate, which is conducive to ensuring that the electrode can be raised before the furnace is poured normally, and the electrode pressure-discharge cycle and pressure-discharge amount can be controlled under the premise of normal furnace pouring.
Electrode pressure release and lifting
In the smelting process, the pressure release and lifting of the electrode are the key steps.Through the precise control of the control cylinder and the pressure and discharge cylinder, the lifting of the electrode shell and copper tile can be realized, thereby ensuring the stability and controllability of the electrode in the smelting process.At the same time, this design can also meet the special requirements of brown corundum dumping furnace smelting, that is, under the premise of ensuring that the electrode can be raised before the furnace is poured normally, the cycle and amount of electrode pressure discharge can be controlled.
Economic and social benefits
The application of self-baking electrodes in the smelting of brown corundum and black corundum has not only improved production efficiency and product quality, but also brought significant economic and social benefits.On the one hand, by reducing production costs and energy consumption costs, the profitability of enterprises has been improved; on the other hand, the wide application of self-baking electrodes has also helped to alleviate the problem of tight electrode supply and promote the healthy development of the abrasive industry.
