Graphite electrode, graphite, graphite anode is industry will use three kinds of equipment or materials, their use is directly related to production safety and efficiency. If the materials appear oxidation corrosion problems, industrial production can not be the normal operation, safety index greatly increased. To solve the problem of high temperature oxidation corrosion material also reflect a country's science and technology level, domestic Beijing Chi Sheng Wei Hua company closed high temperature oxidation resistant coatings with high technology content, strongscientific research technology.
The temperature can reach 1400 ℃ graphite electrode during normal operation, in such a high temperature, the graphite electrode lining in high temperature flame grill, heat preservation brick, lining insulation wool insulation material high temperature very oxidative aging, material crisp, decrease the insulation effect, graphite electrodesafety index dropped sharply. This graphite electrode lining 3-5 graphite electrode lining should be replaced a number of, and cause material waste, reducing graphite electrode normal working hours, for enterprises is to throw the helve after the hatchet!
Graphite anode plate under the environment of high temperature oxidation corrosion is faster, the oxidation of graphite anode plate refers to Shi Moyang plate in high temperature gas and oxygen or oxygen-containingsubstances such as water vapor, CO2, SO2 and other chemical reaction, into graphite anode oxide, graphite anodeoxide and graphite anode plate away, can not form a whole. High temperature corrosion problems in the petrochemical, energy, power, metallurgy, aerospace and other fields. Graphite anode corrosion at high temperatureoxidation which will cause the graphite anode plate appear brittle layer, hardness, strength, toughness, Shi Moyangplate index decreased greatly, very easily lead to major accidents and explosion.
High temperature graphite including graphite electrode, graphite and graphite crucible three, these three kinds ofmaterials in the graphite under high temperature, the graphite is prone to oxidation combustion reaction, resulting inthe rubber surface carbon layer porosity increase and loose structure, affect the service life. In conventional steel ladle baking for example, carbon (graphite) refractory after baking the general surface decarburization loose layerabove 15mm, decarburized layer in steel containing quickly eroded. Graphite electrode loss of steel mills to account for more than 1/10 of the cost of steel production, high temperature oxidation in Zhi Wei Hua Sheng laboratory to see, a 3 kg of graphite crucible for 3 hours at the temperature 1600 ℃, the weight of more than 30%, that is 3 kg ofgraphite crucible is changed to 2 kilograms, oxidation really soon. Graphite is more precious materials, corrosioncaused by oxidation of enterprise production cost increase, energy waste materials.
Integrated afore-mentioned, high temperature, graphite, graphite anode oxidation at high temperature can produceharm, and prevent oxidation under significant security implications and energy efficiency. In order to solve the high temperature graphite electrode, graphite, graphite anode oxidation, to find a material, this material has high temperature resistance, good compactness, strong oxidation resistance, adhesion level and other factors.Remember in the multilateral understanding, one can fully meet the above indicators of material ---ZS-1021 high temperature resistant sealing coating, the coating with high temperature resistance, Chi Sheng Wei Hua special high-temperature solution, temperature can reach 1800 ℃, can long time fire barbecue, material using nano scalesheet structure, good compactness, hardness can reach 7-8H, the hardness is higher than that of graphite anode plate hardness. The paint can form a dense coating on graphite electrode, graphite, graphite anode plate, with a strong anti rust anti-corrosion, anti-oxidation, anti discoloration, wear-resistant properties. ZS-1021 high temperature resistant sealing coating on graphite electrode, graphite, graphite anode plate and so on, to prevent the high temperature oxidation rate can reach 80%, the material energy utilization rate can reach more than 90%, industrial high temperature materials for production safety accident rate can be decreased by more than 95, objective data.
