graphite, graphite anode plate high temperature anti-oxidation coatings have excellent performance. It is a place rich in hp, uhp graphite electrodes, refine, furnaces. hp, uhp graphite electrodes, refine, furnaces, graphite, and graphite anode plates are all three types of equipment or materials that must be used in industry. The quality of their use is directly related to the safety and efficiency of industrial production. If the material has oxidation and corrosion problems, industrial production will not be able to operate normally, and the potential safety hazard index will increase greatly. Solving the problem of oxidation and corrosion of high-temperature materials also reflects the level of science and technology in a country.

The temperature of hp, uhp graphite electrodes, refine, furnaces can reach 1400 ℃ during normal operation. Under such high temperature, hp, uhp graphite electrodes, refine, furnaces are lined under high-temperature flame barbecue, and the lining of thermal insulation bricks, thermal insulation cotton, etc. Thermal insulation materials are extremely oxidative and aging at high temperatures, the materials become brittle, the thermal insulation effect is reduced, and the safety index of hp, uhp graphite electrodes, refine, and furnaces drops sharply. In this way, hp, uhp graphite electrodes, refine, furnaces lining 3-5 years hp, uhp graphite electrodes, refine, furnaces lining must be replaced by a batch, and cause material waste, reduce hp, uhp graphite electrodes, refine, furnaces are normal Working hours, for the enterprise, it is a loss of wife and loss of soldiers!

Graphite anode plates oxidize and corrode faster in high-temperature environments. High-temperature oxidation of graphite anode plates means that graphite anode plates undergo chemical reactions with oxygen or oxygen-containing substances such as water vapor, CO2, SO2, etc. in a high-temperature gas phase environment to transform into graphite anode plates. 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. High temperature corrosion and oxidation of graphite anode plate will cause embrittlement layer of graphite anode plate, and the index of graphite anode plate such as hardness, strength and toughness will drop greatly, and it is easy to cause major safety accidents such as explosion.

Graphite at high temperature includes hp, uhp graphite electrodes, refine, furnaces, graphite molds and graphite crucibles. In these three materials, graphite is prone to oxidation and combustion reactions at high temperatures, resulting in the porosity of the carbon layer on the surface of the material. Increase and loose structure, affect the service life. Taking the conventional baking of ladle as an example, after baking, the carbon-containing (graphite) refractory generally produces a decarburized loose layer of more than 15mm on the surface, and the decarburized layer is quickly eroded after the steel is contained. The loss of graphite hp, uhp graphite electrodes, refine, and furnaces in steel mills accounts for more than one-tenth of the production cost of steel mills. In the Zhisheng Weihua High Temperature Oxidation Laboratory, we saw that a 3 kg graphite crucible at a high temperature of 1600 ℃ lasts 3 times. After an hour, the weight has been reduced by more than 30%, that is, a 3 kg graphite crucible will become 2 kg at a time, and the oxidation is really fast. Graphite is a relatively expensive material. Corrosion and oxidation cause increased production costs and waste of energy materials.

In summary, the hazards caused by high-temperature oxidation of graphite and graphite anode plates at high temperatures, and the significant safety significance and energy-saving benefits of preventing oxidation. To solve high temperature oxidation of hp, uhp graphite electrodes, refine, furnaces, graphite, graphite anode plates, it is necessary to find a material that has high temperature resistance, good density, strong oxidation resistance, and first-class adhesion. Elements. Remember that under the understanding of many parties, we have obtained a material that can fully meet the above-mentioned indicators—ZS-1021 high temperature resistant sealing coating. This type of coating has high temperature resistance. It uses Zhisheng Weihua’s special high-temperature solution, and the temperature can reach 1800℃. Long-term fire-resistant grilling. The material adopts nano-scale fish-scale structure with good compactness. The hardness can reach 7-8H, which is higher than that of graphite anode plate. The coating can form a dense coating on hp, uhp graphite electrodes, refine, furnaces, graphite, and graphite anode plates. It has strong anti-rust, anti-corrosion, anti-oxidation, anti-tarnishing, and wear-resistant properties. ZS-1021 high temperature resistant sealing paint is applied to hp, uhp graphite electrodes, refine, furnaces, graphite, graphite anode plates, etc., to prevent oxidation rate at high temperature can reach more than 80%, material energy-saving utilization can reach more than 90%, industrial The safety accident rate of high-temperature production materials can be reduced by 95%.
