 The mechanical strength of electrode paste includes compressive strength, flexural strength and tensile strength 　　The electrode paste height refers to the height from the upper end of the electrode clamp 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 delamination, or the electrode barrel is damaged due to the pressure of the paste column is too high. If the electrode paste column is too low, it is difficult to obtain a dense electrode due to the pressure of the paste column is too small and the filling property is poor. The electrode paste is consumed too quickly. The proper height of electrode paste column can improve the quality of electrode baking and reduce consumption. 　　Electrode paste is the conductive electrode of various submerged arc furnaces and is an indispensable product in industrial production. In the national standard of electrode paste, there is no mechanical strength q

 Electrode paste is a relatively simple product in the production of carbon products, but their production links are basically the same from the calcination of raw materials to crushing, screening and the front-end of ingredients. Moreover, it is very important to directly affect the output of finished products, the cost of production, the final quality of products, the scale of capital construction, the investment of capital construction and the cycle of capital construction. 　　In order to obtain good products and control the performance of products, regular carbon production enterprises with scale must first break and screen the calcined carbon raw materials, store the materials separately according to various particle sizes, then design the formula according to the use, variety and specification of the products, and strictly measure the ingredients according to the formula. In order to obtain good products, ensure the good performance of products and ensure the use of products.

 The new type of electrode paste is made of refined raw coal, desulfurizer, combustion-supporting agent and other materials. It is made through fine washing, desulfurization, and vacuum stirring mechanisms. It can be processed into rectangles, squares, oval shapes and other shapes according to user needs. Weight of lumpy product. The product has the following characteristics (compared with natural lump coal): 1. Uniform particle size and regular shape; 2. The void ratio is high, and the reaction activity is high; 3. The thermal efficiency is 20% higher than that of raw coal; 4. Reduce emissions of hazardous substances by 40%; 5. The broken rate is reduced by 30%; 6. Reduce the screening process. In the process of vigorously promoting new energy production, the new electrode paste will be a new type of environmentally friendly product that replaces raw coal, especially for smelting enterprises, 20%-30% of electrode paste can be added to reduce the amount of coke and greatly reduce smelt

 The use process and consumption of the electrode paste In terms of the characteristics of use, the electrode paste is a continuous self-baking electrode. During use, the outer layer is a cylinder made of a 1-2mm thick steel plate. The electrode paste is regularly added to the cylinder. As the production progresses, the electrode paste is gradually softened-melted-baked. During roasting, a large amount of volatile matter is released. After entering the conductive clip part of the electrode, it changes from semi-coking to complete coking due to the high temperature, and finally becomes a conductive carbon electrode. The electrode paste is baked into a conductive electrode by various heat of the electric furnace itself, so it is called a self-baking electrode. During the working process of the electrode, a section of cylinder is connected to the top of the electrode at regular intervals, and a certain amount of electrode paste is added, and this is repeated.

 The two materials of electrode paste and smelting flux seem to have nothing to do with each other, but many engineers in the smelting industry crush the electrode paste into 5-10mm particles with a jaw crusher, which is used as a material for repairing the bottom of the furnace and used as a smelting flux. . The reason, let me talk about it slowly. Melting flux is a mixture of various materials formulated and then heated and melted. The melting method can be heated by flame or arc, and the heating temperature is generally 1500 to 1600 degrees Celsius. During the entire heating and melting process, the carbonate in the ore is decomposed, the high-valence manganese is reduced to MnO and forms silicate with SiO2, and the SiO2 is burned. Then pour the refined flux into water at a temperature lower than 20 degrees Celsius to form the flux into particles, which is called wet method; or use compressed air to blow the molten flux into small particles, which is called dry method. The wet-proce
