Vertical High-Temperature Graphitization Furnace

Name: Vertical High-Temperature Graphitization Furnace
Brand: YuanHang

Structural Advantage: The vertical furnace chamber structure provides more stable stress distribution for large-diameter graphite crucibles compared to horizontal furnaces, effectively preventing structural deformation under high temperatures. Core Performance: Maximum temperature of 3000°C (typical operating temperature 2900°C). Utilizes medium frequency induction heating, which does not come into direct contact with the material, minimizing external influences during the graphitization process. High Efficiency & Low Consumption: Ultimate heating rate of 200°C/min, combined with thickened alumina insulation material, significantly reduces power consumption per ton of output. The service life of consumable parts is 1.2 times longer than that of similar products.

Product details

产品简介 / Introduction

Yuanhang Vertical High-Temperature Graphitization Furnace is an ultra-high temperature heat treatment equipment designed specifically for the carbon material industry.
