How is the oxidation rate of the graphite tube?

       High temperature furnace, graphite, metal high temperature oxidation may occur damage, as well as serious safety risks and energy saving benefits to prevent oxidation. To deal with the high temperature oxidation of kiln, graphite and metal at high temperature, it is necessary to find the materials with high temperature resistance, good density, strong oxidation resistance, first-class adhesion and other elements. 

       After many inquiries, the material can fully achieve the above target- - -ZS-1021 high temperature resistant stop coating, this coating has high temperature resistance, using the wisdom Sheng Weihua special high temperature solution, temperature resistance up to 1800℃. The loss of graphite electrode accounts for more than one-tenth of the production cost of steel mills. Zhisheng Weihua high temperature oxidation laboratory saw that 3 kg of graphite crucible was kept at 1600℃ for 3 hours, and the weight was reduced by more than 30%., That is, a 3 kg graphite crucible into 2 kg at a time, the oxidation speed is really very fast.

       Graphite is a more expensive material than the precious graphite powder. Corrosion and oxidation lead to increased interest in production and waste of energy materials. It offers both fire resistance and long-time barbecues. The material is made of nanoscale fish scales with good fineness and hardness.7-8H, higher than metal. The coating can form a fine coating on the kiln, graphite and metal, and has a strong anti-rust, corrosion prevention, anti-oxidation, anti-graphite powder color change, wear resistance and other characteristics. ZS-1021 high temperature resistant coating is applied in kiln, graphite, metal, etc., to prevent the high temperature oxidation rate can reach more than 80%, the material energy saving utilization rate can reach more than 90%, the accident rate of safe industrial high temperature production materials can be reduced by more than 95%, objective data. 

       Graphite powder at low temperature includes graphite electrode, graphite tube and graphite crucible, as summarized above. The graphite in these three materials is easy to oxidation and burn at high temperature, the porosity of the rubber carbon layer on the surface of the material is increases, and the structure is loose, which affects the service life. Take the baking of conventional graphite powder in the ladle as an example, after the baking of carbon (graphite) refractory material, there is usually more than 15mm of decarbonization loose layer on the surface, and the decarbonization layer is quickly corroded after the steel filling.
