The high-temperature circulating fan in the metal strip continuous annealing furnace blows 800°C HN protective gas to the strip surface and plays a core role as a power source for jet heating or a suspended air source to support the strip. High-temperature resistant alloy materials are one of the main materials for manufacturing high-temperature fans. Their high-temperature mechanical properties, high-temperature creep resistance and high-temperature oxidation resistance are of great significance to the manufacture and use of high-temperature fans. This article will introduce the experimental research results of Haynes HR-120 in the manufacturing of high-temperature fans at 800°C.
1. Overview of Hastelloy HR-120
Hastelloy is a high-temperature alloy material composed of nickel, chromium, iron, aluminum, etc. It has good high-temperature oxidation resistance, high-temperature strength and high-temperature creep properties. HR-120 is a low-cost Hastelloy alloy, its price is only half of Inconel 601, but its high-temperature creep resistance and high-temperature oxidation resistance are very good, and it is suitable for the manufacture of high-temperature fans with operating temperatures above 800°C.
2. Selection of high-temperature resistant alloy materials in high-temperature fan manufacturing
In the manufacturing of high-temperature fans, the selection of high-temperature resistant alloy materials is very important. Common high-temperature alloy materials include Inconel 601, Inconel 617, Inconel 625, HR-120, etc. They all have their own advantages and disadvantages. Inconel 601 has good high-temperature oxidation resistance, but its high-temperature creep resistance is poor; Inconel 617 has good high-temperature creep resistance, but its high-temperature oxidation resistance is poor; Inconel 625 has good high-temperature resistance Oxidation properties and high temperature creep resistance, but its price is more expensive. In contrast, HR-120 not only has better high-temperature oxidation resistance and high-temperature creep resistance, but also has obvious price advantages, so it has broad application prospects in high-temperature fan manufacturing.
3. Experimental research on Haynes HR-120 in the manufacturing of high-temperature fans at 800°C
Through experimental methods, the high-temperature mechanical properties, high-temperature creep resistance and high-temperature oxidation resistance of several high-temperature resistant alloy materials were comparatively analyzed. The conclusion shows that the high-temperature creep resistance and high-temperature oxidation resistance of HR-120 alloy are better than Inconel 601 and Inconel 617, with their obvious price advantages, are very suitable for the manufacture of high-temperature fans with operating temperatures above 800°C. Therefore, in the manufacturing of 800°C high-temperature fans, choosing HR-120 as a high-temperature resistant alloy material has certain advantages.
4. Conclusion
The manufacturing of high-temperature fans places higher requirements on the selection of high-temperature resistant alloy materials. Among several common high-temperature alloy materials, HR-120 alloy not only has good high-temperature oxidation resistance and high-temperature creep resistance, but also has obvious price advantages. It is very suitable for the manufacture of high-temperature fans with operating temperatures above 800°C.
