Graphite electrode, graphite, graphite anode plate high temp
Graphite electrodes, graphite, and graphite anode plates are all three kinds of equipment or materials that must be used in industry. Their use is directly related to the safety and efficiency of industrial production. If the material has oxidative corrosion problems, industrial production will not function properly and the safety hazard index will increase greatly. Solving the problem of oxidative corrosion of high-temperature materials also reflects the level of science and technology in a country. The domestic high-temperature closed anti-oxidation coatings of Beijing Zhisheng Weihua Company have high technical content and strong scientific research technology.
When the graphite electrode works normally, the temperature can reach 1400 °C. Under such high temperature, the graphite electrode is lined under the high-temperature flame grilling, and the heat-insulating material such as the heat-insulating brick and the heat-insulating cotton lining is highly oxidized and aged, and the material is crispy. The thermal insulation effect decreased, and the graphite electrode safety index dropped sharply. In this way, the graphite electrode lining should be replaced with a batch of graphite electrode lining for 3-5 years, and the waste of materials and the normal working time of the graphite electrode can be reduced. For the enterprise, the wife and the soldier are lost!
The graphite anode plate is oxidized and corroded in a high temperature environment. The high temperature oxidation of the graphite anode plate means that the graphite anode plate is chemically reacted with oxygen or oxygen-containing substances such as water vapor, CO2, SO2, etc. in a high-temperature gas phase environment, and converted into a graphite anode plate. Oxide, graphite anode plate oxide has been separated from the graphite anode plate and cannot form a whole. High temperature corrosion problems are common in petrochemical, energy, power, metallurgy, aerospace and other fields. Graphite anode plate high temperature corrosion oxidation will cause the graphite anode plate to appear embrittled layer, hardness, strength, toughness and other indicators of graphite anode plate drop greatly, it is easy to produce major safety accidents such as explosion.
Graphite at high temperature includes graphite electrode, graphite mold and graphite crucible. The graphite in these three materials is prone to oxidative combustion reaction at high temperature, resulting in increased porosity and loose structure of the surface of the carbon layer of the material. life. Taking the conventional baking of ladle as an example, the carbon-containing (graphite) refractory material generally has a decarburized loose layer of 15 mm or more after baking, and the decarburized layer is quickly eroded after being filled with steel. The graphite electrode loss of the steel mill accounts for more than one tenth of the steel mill's production cost. In the Zhisheng Weihua High Temperature Oxidation Laboratory, a 3 kg graphite crucible has been reduced in weight by 30 hours after the high temperature of 1600 ° C for 3 hours. More than %, that is, 3 kg of graphite smashed into 2 kg, oxidation is really fast. Graphite is a relatively expensive material, causing increased production costs and waste of energy materials due to corrosion oxidation.
In summary, the high temperature oxidation of graphite and graphite anode plates at high temperatures can cause hazards and prevent significant safety and energy saving benefits under oxidation. To solve the high temperature oxidation of graphite electrode, graphite and graphite anode plate at high temperature, it is necessary to find a material which has the characteristics of high temperature resistance, good compactness, strong oxidation resistance and adhesion level. Remember to learn from a multi-party, a material that can fully meet the above-mentioned indicators---ZS-1021 high temperature sealing coating, this coating is high temperature resistant, using Zhisheng Weihua special high temperature solution, the temperature can reach 1800 °C, can Long-term refractory barbecue, the material adopts nano-fish scale structure, good compactness, hardness can reach 7-8H, hardness is higher than the hardness of graphite anode plate. The coating can form a dense coating on the graphite electrode, graphite and graphite anode plate, and has strong rust and corrosion resistance, oxidation resistance, anti-tarnishing effect and wear resistance. ZS-1021 high temperature resistant sealing coating is applied on graphite electrode, graphite, graphite anode plate, etc., to prevent oxidation rate of over 80% under high temperature, energy saving utilization rate of material can reach more than 90%, industrial high temperature production material safety accident rate can be Drop more than 95, objective data.
