On August 23, 2022, China's leading electrothermal alloy material manufacturer: SCPG Alloy Material Technology Corporation released new product information:
From the feedback from trial customers, the company's newly developed high-performance Cr20Ni80 electrothermal alloy wire products for high-power electric furnaces have a trial period of more than one year, and their service life is more than 40% higher than the average level of the same industry in China. Other comprehensive indicators have also been praised by customers. After customer demonstration, we successfully obtained the qualification of qualified suppliers who can participate in the bidding.
It is reported that Cr20Ni80 electric heating alloy has the characteristics of high melting point, high resistivity, low temperature coefficient of resistance, and good oxidation resistance at high, medium and low temperature. one of the basic materials.
China is a major consumer of electrothermal alloys. Based on the strong demand for industrial upgrading and import substitution, SCPG researchers have systematically studied the effects of alloy composition, smelting process, processing technology and heat treatment process on the properties of Cr20Ni80 electrothermal alloys based on material design. Influence law, and further optimized the composition of Cr20Ni80 electrothermal alloy and the whole process production process.
After several rounds of laboratory small ingot type test verification and numerical simulation verification, industrial trial production was actively carried out, and the whole process of production of high-performance Cr20Ni80 electric heating alloy wire products for high-power electric furnaces was successfully opened. The product quality reached the standard and the comprehensive performance reached the international leading level.
