 (1) The measurement should be made twice in each shift, once during the shift, and once during the shift, and make a record. (2) The measuring position of each shift must be in the same position (inner triangle or outer triangle). (3) Each shift should decide how much electrode paste should be installed according to the height of the electrode paste. (4) The measuring personnel should be careful not to touch the two-phase electrodes at the same time to prevent electric shock. (5) The measurement must be accurate.

 The anti-oxidation coating graphite electrode is a coated electrode made of graphite electrode as the substrate and sprayed with an oxidation-resistant coating on the surface of the body. The preparation process is to fuse a thin layer of aluminum-based cermet on the surface of the processed graphite electrode. The coating material, which can conduct electricity and is resistant to oxidation, is formed by the eutectic of aluminum and refractory mud with multiple components. Its characteristics and functions are as follows: 1. Provide the electrode with a high-efficiency oxygen barrier layer and a highly conductive outer surface layer, which can prevent the electrode surface from being oxidized and reduce electrode consumption, and can reduce the current density inside the electrode. 2. The anti-oxidation coating can withstand quite high temperature without melting, and the decomposition temperature of the coating is 1850. Above C. 3. The coating is well combined with the electrode sur

 Electrode paste is also called self-baking electrode. It is a kind of semi-finished electrode material made of electric forging coal, residual electrode, etc. as aggregate, and asphalt, tar, etc. as binder. In the process of use, the electrode paste needs to be injected into the submerged arc furnace. When it is heated to about 400 degrees, the electrode paste melts and then completes sintering to become a solid. When it is heated to 800 degrees, the arc combines with the original ore to generate huge heat to complete the ore Smelting. The so-called airtight paste is only for the type of submerged arc furnace. Submerged arc furnace is divided into closed type, semi-closed type and open type. These different types of submerged arc furnaces use electrode pastes. Because of the different furnace types, over time, the electrode pastes applied to closed submerged arc furnaces are called closed electrode pastes, or closed pastes for short; they are used in open or semi-closed arc furnaces.
