electrode paste price
Introduction to the use and production of electrode paste price
The electrode paste price is also called self-baking electrode. It relies on the heat in the submerged arc furnace to complete the roasting. Therefore, matching the consumption speed of the electrode and the roasting speed is the key to the use of the electrode paste price. Due to the development of submerged arc furnace technology, gradually In the direction of large-scale and airtight development, the electrode has developed from an open furnace to a closed furnace during the baking process. The heat obtained by the electrode from the furnace is greatly reduced. This requires the improvement of the sintering performance of the electrode paste price to make up for this. One deficiency. For the manufacturers of electrode paste price, the two taboos are soft and hard electrode breakage. Soft breakage is more terrible and can easily cause accidents. Hard fracture is caused by insufficient strength of the electrode paste price after sintering; soft fracture is that the electrode sintering speed is not as fast as the consumption speed, and the lowering is too fast. The electrode is not completely sintered and cannot withstand the stretching and lateral impact of the lower electrode, causing fracture. These two problems are directly related to the performance of the carbon manufacturer’s electrode paste price, and are also related to the operation during use.
There are only two main links in the production of electrode paste price, namely ingredients and kneading. Among them, the kneading is basically the same at present, as long as the kneading equipment is a regular equipment (the above intermittent double-shaft kneading pot), the kneading temperature and time can be controlled in the process. The key to the ingredients is a reasonable formula; the selection of raw materials, the particle size ratio, and the softening point of the binder asphalt and the amount of binder used are especially important.
At present, the main problem that plagues manufacturers is that the roasting speed of the electrode paste price is too slow, so some manufacturers adopt methods to reduce the amount of asphalt used. This method is effective to a certain extent, but the low amount of pitch causes the fluidity of the electrode paste price to deteriorate, and the electrode paste price is not easy to be filled in the electrode barrel. The poor density after sintering is likely to cause hard fracture. Another method is Lower the softening point of the pitch and increase the sintering speed of the electrode. However, the softening point of the pitch cannot be reduced indefinitely. Because the pitch with a too low softening point reduces the coking rate of the pitch, the strength of the electrode is also reduced, and the phenomenon of hard fracture occurs.
Therefore, in addition to properly mastering the above two methods in the production of the electrode paste price, the sintering speed of the electrode must be improved through the adjustment of the formula. For example, the graphite material with good conductivity and heat transfer performance is appropriately added in the formula to increase the electrode. The conduction heat obtained from the furnace can speed up the firing speed, and at the same time try to reduce the consumption of the electrode to reduce the speed of the electrode lowering, which can also match the consumption of the electrode and the firing. I began to study the production technology of electrode paste price in the 1980s, and conducted experiments on the production of electrode paste price for the electric nickel furnace of Northwest Jinchang Company. I also adopted certain additives in the asphalt, which also had a certain effect. After that, he successively developed products for a number of large-scale calcium carbide furnaces and ferroalloy furnaces and gained certain experience. Therefore, the production of the electrode paste price should prescribe medicines, multi-pronged, comprehensive consideration, appropriateness, and complementary advantages in order to produce good products and satisfy users.
