The height of electrode paste refers to the height from the upper end of electrode clip to the top of electrode paste. If the electrode paste is too high, the coarse and fine particles in the electrode paste are prone to delamination, or the electrode cylinder is swollen due to the pressure of the paste column. If the electrode paste column is too low, it is difficult to obtain a dense electrode because the pressure of the paste column is too small and the filling property is poor. Electrode paste consumption is too fast.
The proper height of electrode paste column is conducive to improving the quality of electrode roasting and reducing consumption. Before filling, the electrode paste should be broken into 80~100mm small pieces, so that the electrode paste can pass smoothly between the two ribs. If the particle size is too large, it is easy to cause electrode paste suspension failure; If the particle size is too small, it is easy to cause spray paste. It is better to buy the finished material of electrode paste. If the material supplied by the manufacturer is of qualified particle size, it can be directly filled. The powder of broken electrode paste is reduced, the utilization rate of electrode paste is improved, and the cost of calcium carbide is reduced.
Use a forklift to transport the trolley or special tools to the calcium carbide furnace, and use an electric hoist to hoist it into the electrode barrel. Pay attention to hoisting during loading *. When adding electrode paste, pay attention not to scatter the electrode paste on the equipment outside the electrode barrel, so as to avoid electric fire accidents. Each time the electrode paste is filled, the site should be cleaned, especially the electrode paste scattered on the equipment. When adding electrode paste, people should not touch the two electrodes at the same time to prevent electric shock. It should also be noted that conductive objects should not remove the two-phase electrodes at the same time to prevent power connection. In addition, domestic electrode pastes are mostly square and three piece connected.
It needs to be broken in use. At present, some manufacturers have improved the shape of electrode paste to make an ellipsoid with appropriate particle size. For example, the sealed electrode paste produced by Fuzhen carbon is 72mm*65mm*120mm, with a mass of about 500g. It has the following advantages:
(1) convenient loading, unloading, storage and transportation;
(2) The finished products, loading and other processes have been screened and slag removed for many times, without weight loss;
(3) Less dust pollution, *, reliable;
(4) The particle size is moderate, and there will be no electrode paste spray accident.
