FAQ
Q: What size electrodes are used in phosphorus furnaces?
A: Yellow phosphorus furnaces typically use graphite electrodes in the range of 300-500mm diameter, depending on furnace power and transformer capacity. The exact electrode size is determined by the furnace design and operating current. Please consult us with your furnace specifications for the optimal electrode size recommendation.
Q: How do you control electrode quality?
A: Our electrodes undergo rigorous quality control including resistivity testing, density measurement, flexural strength testing, and visual inspection. Each batch is tested to ensure it meets the required specifications before shipment. We also provide mill test certificates with each shipment.
Q: What is the typical electrode consumption rate?
A: Electrode consumption depends on furnace type, operating conditions, and electrode quality. For phosphorus furnaces, typical consumption is 50-80 kg/ton of phosphorus produced. Proper furnace operation and using high-quality electrodes can significantly reduce consumption rates.
