30+ YEARS OF EXPERIENCE IN CARBON INDUSTRY

DC electrode paste is an indispensable core conductive material in the field of submerged arc furnace smelting. From ferroalloys to calcium carbide production, from industrial silicon smelting to nickel-iron processing, DC electrode paste has always played a crucial role. High-quality DC electrode paste not only determines smelting efficiency but also directly affects production energy consumption and equipment safety. Therefore, selecting and using the right DC electrode paste is a core aspect of cost reduction and efficiency improvement for metallurgical enterprises.

DC electrode paste is made from anthracite and metallurgical coke powder as the main aggregates, combined with modified coal tar pitch as a binder, through precise proportioning and kneading

. The ash content, resistivity, and other indicators of the DC electrode paste directly determine its performance. During submerged arc furnace operation, the DC electrode paste forms conductive electrodes through a self-baking process. Its high-temperature resistance and thermal shock resistance allow it to withstand arc temperatures of 3500℃, while its density slows down oxidation and extends electrode life.

In ferroalloy smelting, controlling the consumption of DC electrode paste is crucial to production costs. Each ton of ferrosilicon production requires 35-50 kg of DC electrode paste, and optimizing the DC electrode paste formula can effectively reduce this consumption. In calcium carbide furnaces and industrial silicon furnaces, the sintering speed of the DC electrode paste directly affects furnace stability

. High-quality DC electrode paste can prevent accidents such as soft breakage and hard breakage, and the adaptability of the DC electrode paste is a core requirement for large-capacity submerged arc furnaces.

Currently, customized DC electrode paste is becoming a trend to meet the needs of large-scale submerged arc furnaces

. The production process of DC electrode paste is constantly being upgraded, from raw material screening and grinding to mixing temperature control; every step aims to improve the conductivity and mechanical strength of the DC electrode paste. As a fundamental material for energy-intensive industries, the technological upgrade of DC electrode paste is driving the metallurgical industry towards green and efficient development. Selecting the right DC electrode paste is fundamental to ensuring stable production and controllable costs for enterprises.
