Overview

Yuanhang Large-Scale Medium Frequency Graphitization Furnace is a high-end industrial electric furnace specially developed for high-temperature treatment of carbon materials in large batches. Compared with the commonly used Acheson furnace in the market, it effectively solves a series of industry challenges such as prolonged power-on time, significant heat loss, large temperature differences in the furnace core, and the mixing of materials with resistor materials. With its high throughput and excellent temperature uniformity, this furnace type has become an ideal choice for the preparation of advanced materials like carbon nanotubes and high-purity graphite powder.
