 Electrode accidents are common accidents in ferroalloys and calcium carbide enterprises smelted by submerged arc furnaces. The cause of electrode accidents is analyzed and judged accurately, and targeted preventive measures can be taken to reduce the occurrence of electrode accidents. However, due to the analysis of electrode accidents, it is supplied by electrode paste. The manufacturer and the electrode paste use the interference of multiple factors. To accurately determine the cause of the electrode accident requires objective evidence recognized by both parties, and the electrode section is a good objective evidence, so the analysis of the electrode section is of great significance. . 1. Electrode paste segregates, resulting in layering of aggregate and powder 1. Section status: There is obvious particle layer segregation on the section of the electrode. According to the size and cross-section of the radiant heat source for electrode baking, there are two situations, one is the ac

 This process mainly has several forms in terms of the layout of process equipment. A flat layout: all the crushing equipment, screening equipment, milling equipment, and storage bins are all on the same plane. It is basically manual operation, the environment is very poor, and the labor intensity is high. This arrangement method is mainly used by some small enterprises and manufacturers with small output. The process is simple and the investment is small. Not suitable for large-scale production requirements and environmental protection requirements. Belongs to extensive production methods. It is characterized by low investment, high labor intensity, high pollution, and low efficiency. In today's social environment where people-oriented, safety and environmental protection are first, small factories should also improve the method of eliminating this kind of medium-crushed ingredients. graphite electrode, cold ramming paste, semi coke, electrode paste, graphite carbon block, smelt m

 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 residual electrode is the part that must be replaced with a new anode from the electrolytic cell in order to prevent the steel claws from melting after the pre-baked anode has been used in the electrolytic cell for a period of time. After high-temperature roasting, the residual pole has higher mechanical strength and lower porosity than petroleum coke. Using residual pole as a raw material for the production of carbon products can improve the quality of carbon products to a certain extent. As the "heart" of the calcium carbide furnace, the electrode paste, which is called a carbon functional material, requires sufficient strength and thermal shock resistance. With the advent of the low-carbon era, it is an inevitable trend for large enclosed calcium carbide furnaces to replace small semi-closed calcium carbide furnaces and open calcium carbide furnaces. Therefore, higher requirements for the quality of electrode paste are also put forward. Rongxin Carbon has been special

 So, is there really an electrode paste without coal tar? have! Our factory has processed 2000 tons of electrode paste without coal tar for a group of well-known companies in the industry. Coal tar is used as a binder in the manufacture of electrode paste. Although coal tar is missing, there is pitch. Of course, this is only based on the special requirements of customers. Generally speaking, the electrode paste requires coal tar. The combination of coal tar + pitch binder can make the electrode paste melt perfectly and then sintered in the submerged arc furnace. If the coal tar is missing It will affect the softening process of the electrode paste. The goose egg-shaped electrode paste, trapezoidal electrode paste, and cylindrical electrode paste produced by our factory are all formulated with coal tar. If it is nickel-iron high-standard airtight paste, the requirements for the formula are more stringent. Therefore, the standard electrode paste needs to be added with coal tar. There are

 As the self-baking electrode of submerged electric furnace, electrode paste has been widely used in the smelting of various products of submerged electric furnace. Although the cost of electrode paste in the production of calcium carbide, ferroalloy and other products is relatively low, the quality of the electrode paste and the firing of the electrode directly affect the stability of the operation of the submerged electric furnace. Due to the various types of submerged electric furnaces, the different furnace conditions, and the increasing capacity of electric furnaces, when the quality index of the electrode paste meets the requirements, the roasting quality plays a decisive factor, which requires us to focus on calcium carbide, ferroalloys, etc. The actual production of the product starts with the management of the electrode paste, strictly implements the operating procedures, regularly and quantitatively lowering the electrodes, and maintains the normal and stable operating parame
