Brief Introduction
We produce and sell graphite electrodes and nipples to them. According to its high quality and low quality, it can be divided into ordinary power graphite electrode, high power graphite electrode and ultra high power graphite electrode. Any interests for our graphite electrode, pls email us for more information :info@refractorymanufacture.com
