To enrich the product range, Minhe Guangda Carbon has newly built a production plant covering an area of 6,000 square meters in the second phase and added various types of production equipment, including a 350 KW vibration forming machine, an 18-chamber ring-type natural gas roasting furnace (with a furnace chamber size of 1.55x4.5x7m), and a CNC large-scale automatic processing line for carbon/graphite electrodes, etc. It is mainly used for the production of large-size carbon/graphite electrodes for metal silicon in electric furnaces with diameters ranging from φ960 to φ1320mm. This type of electrode is made mainly from graphitized petroleum coke and coal tar pitch as the binder. It is produced through processes such as raw material preparation- batching - kneading - forming - baking -(for graphite electrodes, impregnation - graphitization is also required)- machining. In metal silicon applications, with its low resistivity, low ash content, high bulk density, good electrical and thermal conductivity, and high mechanical strength, it can withstand the large current density during high-temperature smelting processes, resist the internal stress caused by changes in furnace temperature, and has good thermal shock resistance. The electrode is equipped with male and female threads/single joints. The thread processing accuracy is high, which facilitates the rapid extension of the electrode during the continuous smelting process and ensures the continuous and stable production. There is no need for electrode cylinders, which effectively reduces the iron element content in the smelting products and improves the purity of the smelting products. It has obvious comparative advantages in effectively reducing smelting costs (electricity consumption, electrode consumption), increasing smelting output, improving smelting efficiency and safety, etc. The annual production capacity of large-sized carbon/graphite electrodes of the company is 20,000 tons.
