Causes of electrode hard breaking accident
When the electrode paste changes from solid to liquid, the mechanical strength drops to its lowest point when the temperature reaches 400 degrees Celsius.
Characteristics of graphite electrodes
As mentioned earlier, the current of the calcium carbide furnace is converted into heat energy by inputting the electrode into the furnace. In order for the electrode to work normally at the high temperature generated by the arc
New energy electrode paste airtight paste
It can be processed into rectangles, squares, oval shapes and other shapes according to user needs. Weight of lumpy product.
Application of self-baking electrode in submerged arc furnace
The use of high-strength electrode paste was tested in a 20MVA submerged arc furnace. The results show that it can effectively prevent electrode accidents and play a key role in improving the economic indicators of smelting.
Definition of electrode paste height
The height of the electrode paste refers to the height from the upper end of the electrode clip to the top of the electrode paste.
The important role of electrode paste in submerged electric furnace
Therefore, the electrode paste occupies an extremely important position in the above submerged electric furnaces, so it is called the “heart” of this type of electric furnace.
Electrode paste application range
The use of electrode paste to supply ferroalloy furnaces, calcium carbide furnaces and other electric furnace equipment has become another trend. The main raw materials for the production of electrode paste are anthracite and metallurgical coke. Currently, two electrode pastes with different formulations are produced.
One is the so-called standard electrode paste. It is widely used in ferroalloy furnaces and medium and small calcium carbide furnaces. This electrode paste uses medium pitch with a softening point of 65-75°C (determined by the mercury method) as the binder.
Factors affecting the plasticity of electrode paste
The electrode paste is burned in a submerged electric furnace (sintered in an electrode barrel made of steel plate) and consumed, so it is also called a continuous self-baking electrode.
Pasting process of electrode paste
Reduce the control height of the paste column from 4-4.5 meters to 3.5-4 meters for control. The installation of electrode paste follows the principle of adding less and more frequently.
