e contact surface between the end of the electrode and the coke layer at the bottom of the furnace. If it is a new electrode, the steel plate at the bottom of the head should be thicker.
calcium carbide furnace
The size of the electrode diameter is determined by the current density allowed by the current passing through the electrode cross-sectional area. If the diameter is small, the allowable current density is large
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
In production practice, depending on the specific circumstances, there may be many factors. Everyone is welcome to communicate.
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.
The relationship between the ash content and the specific resistance is affected by many factors, such as the material itself, the composition of the ash, the processing temperature, and the material configuration. Ratio, product density, etc.
The calcined anthracite is fed by an electromagnetic vibrating feeder, and is fed into a double-layer horizontal vibrating screen and a single-layer horizontal vibrating screen via a belt conveyor and a bucket elevator.
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.
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. If the electrode paste is too high, the coarse and fine particles in the electrode paste are prone to stratification
Electrode paste is a conductive material supplied to electric furnace equipment such as ferroalloy furnaces and calcium carbide furnaces. Electrode paste is also called self-baking electrode.
