Electrode paste is a conductive material used as self-baking electrode in the production of various types of ferroalloys, calcium carbide and other mineral heaters. Due to the different design parameters of the furnace type, the electrode quality parameters required are different. With the rapid development of mineral furnace technology, the electrode as the heart of the normal operation of the mineral furnace, it needs the electrode paste, the quality requirements are more and more stringent. Our company produces asphalt product quality and stability, excellent performance, in the electrode paste sintering temperature of 300 - 800 ℃, as the volatile coal asphalt has been discharged, the remaining coal asphalt has been carbonized to form a network, and a variety of electrode paste raw materials are fused together, the mechanical strength of the product indicators to meet the requirements of the properties of asphalt has a crucial role in the mechanical strength of the electrode paste.
