Electrode paste is an indispensable material in industrial production, widely used in fields such as steelmaking, ferroalloy production, and carbide manufacturing. As one of the main raw materials for electrode paste, forged anthracite has unique characteristics and excellent performance, which plays a decisive role in the quality and performance of electrode paste. This article will explore in detail the characteristics and properties of forged anthracite coal.
Definition of Forged Anthracite Coal
Forged smokeless coal refers to smokeless coal that has undergone high-temperature calcination treatment. The calcination process can remove impurities and moisture from coal, increase the fixed carbon content and mechanical strength of coal, and make it have better conductivity and oxidation resistance.
characteristic
a. High fixed carbon content: The fixed carbon content of forged anthracite coal is usually above 90%, which makes it have excellent conductivity and thermal stability under high temperature conditions.
b. Low ash and low sulfur content: Forged anthracite coal, after high-temperature calcination, can effectively remove the ash and sulfur content in the coal, making it produce less pollutants during combustion and has good environmental performance.
c. High mechanical strength: After high-temperature forging and burning, the mechanical strength of forged anthracite coal is significantly improved, which can withstand high temperature and high pressure environments in industrial production, reduce crushing and wear.
d. Good antioxidant performance: Forged anthracite coal has high antioxidant performance, which can resist oxidation under high temperature conditions and extend its service life.
Performance a. Conductivity: Forged anthracite coal has excellent conductivity, which can effectively conduct current, improve the conductivity of electrode paste, and ensure the efficient operation of equipment such as electric arc furnaces and submerged arc furnaces.
b. Thermal stability: Forged anthracite has good thermal stability, which can maintain structural integrity under high temperature conditions, reduce thermal expansion and contraction, and improve the thermal stability of electrode paste.
c. Antioxidant performance: Forged anthracite coal has strong antioxidant performance, which can effectively resist oxidation at high temperatures, prolong the service life of electrode paste, and reduce electrode consumption.
d. Environmental performance: The low ash and low sulfur characteristics of forged anthracite coal result in less pollutants generated during combustion, and it has good environmental performance, meeting the environmental requirements of modern industrial production.
