Equipment for Glass Kilns Castings Industry knowledge

In view of the high requirements for the oxidation resistance of materials in glass kilns, what special processes or material treatment methods has the company adopted to improve the oxidation resistance of alloy steel parts and extend the service life of the equipment?

In view of the high requirements for the oxidation resistance of materials in glass kilns, Xinghua Dongchang Alloy Steel Co., Ltd. knows that the oxidation resistance is a key factor to ensure the long-term stable operation of alloy steel components in extreme high temperatures and complex chemical environments. To this end, the company has adopted a series of special processes and material processing methods to significantly improve the oxidation resistance of alloy steel components, thereby extending the service life of the equipment.

Material selection and optimization
In terms of material selection, the company strictly screens and optimizes the alloy composition to ensure that the selected alloy steel not only has excellent high temperature resistance, but also has excellent oxidation resistance. Specifically, the company has increased the content of elements such as chromium (Cr) and silicon (Si) in alloy steel. These elements can form a dense oxide film at high temperatures, effectively preventing oxygen from further diffusing into the material, thereby significantly improving the material's durability. antioxidant properties.

Surface treatment technology
In addition to the optimization of the material itself, the company also uses advanced surface treatment technology to enhance the oxidation resistance of alloy steel parts. A commonly used method is thermal spraying technology, which sprays coating materials with excellent anti-oxidation properties (such as aluminum oxide, chromium oxide, etc.) on the surface of alloy steel parts through high temperature to form a hard and dense protective layer. This protective layer can not only effectively isolate the erosion of oxygen and corrosive substances, but also maintain stable chemical properties at high temperatures, thus greatly extending the service life of the components.

The company has also explored and applied chemical heat treatment technologies such as aluminizing and siliconizing. These technologies infiltrate anti-oxidation elements such as aluminum and silicon into the surface of alloy steel to form a solid solution or compound layer with the base metal, thereby improving the anti-oxidation performance of the material. The surface of alloy steel after aluminizing treatment can form a dense aluminum oxide film, which has excellent stability at high temperatures and can effectively resist oxidation and corrosion.

microstructural control
In order to further improve the oxidation resistance of alloy steel parts, the company also focuses on regulating its microstructure. By optimizing the heat treatment process, such as controlling parameters such as heating temperature, holding time, and cooling rate, the grains can be refined, internal defects reduced, and the formation of beneficial precipitated phases promoted. These microstructural changes help improve the density and uniformity of the material, thereby enhancing its resistance to oxidation and corrosion.

Coating and protection technology
In addition to the above-mentioned processes, the company has also developed a variety of coating and protection technologies to further improve the oxidation resistance of alloy steel parts. For example, ceramic coating technology is used to coat the surface of alloy steel with a layer of high-temperature-resistant and corrosion-resistant ceramic materials to form a strong protective barrier. In addition, the company has also researched and applied composite coating technology, through the combined use of multiple coating materials, to achieve complementary advantages and improve the overall performance of the coating.

Quality testing and assessment
In order to ensure that the alloy steel parts produced have excellent oxidation resistance, the company has established a strict quality inspection and evaluation system. By simulating the high temperature and oxidizing environment of a glass kiln, accelerated aging tests and oxidation resistance tests are conducted on components. At the same time, advanced detection methods (such as X-ray diffraction, scanning electron microscopy, etc.) are used to analyze the microstructure and chemical composition of the components to ensure that product quality meets the design requirements.

Xinghua Dongchang Alloy Steel Co., Ltd. has significantly improved the oxidation resistance of alloy steel parts through various means such as material selection and optimization, surface treatment technology, microstructure control, coating and protection technology, and quality inspection and evaluation. Provides more reliable and durable component solutions for glass furnace equipment. These efforts not only extend the service life of equipment, but also create greater economic benefits for customers.
