FAQ
Q: What is the difference between RP, HP, and UHP electrodes?
A: RP (Regular Power) electrodes are for small furnaces and low current density operations. HP (High Power) electrodes have better properties for medium-sized furnaces. UHP (Ultra High Power) electrodes are designed for large EAFs operating at high current densities, with superior strength and lower resistivity. Higher grade electrodes allow faster melting and lower specific consumption.
Q: What size electrodes do you supply?
A: We supply graphite electrodes in diameters from 100mm to 700mm, with standard lengths of 1800mm or 2400mm. Custom lengths and nipple designs are available. Please provide your furnace specifications, and we will recommend the optimal electrode size and grade.
Q: How can I reduce electrode consumption?
A: Electrode consumption is affected by furnace operating conditions, oxygen blowing, and electrode quality. Proper voltage/current settings, controlled oxygen lancing, and using high-quality electrodes with tight nipple connections all contribute to lower consumption rates and reduced operating costs.
