On November 27, 2016, Hunan Zhenhua Analytical Instruments Co., Ltd. signed a procurement contract with CRRC Qishuyan Institute of Locomotive and Rolling Stock Technology for a GYH-A high-temperature anti-oxidation test furnace. After manufacturing and factory commissioning, the equipment was delivered to Changzhou, Jiangsu, on January 20, 2017. Installation, commissioning, operator training, and initial acceptance followed.
A second acceptance was scheduled six months after delivery, subject to stable equipment operation. The milestone was reached in August, completing the final acceptance requirement.
The GYH-A high-temperature anti-oxidation test furnace is designed in accordance with GB/T 13244, “Test Method for Oxidation Resistance of Carbon-Containing Refractory Materials.” The control system records test results automatically.
Oxidation resistance is the ability of a material to withstand corrosive oxidative atmospheres at elevated temperatures. Boiler superheaters, water-cooled wall tubes, turbine casings, and turbine blades are identified as high-temperature components susceptible to oxidation corrosion. The stated oxidation-corrosion-rate limit for materials such as superheater tubing is 0.1 mm/a.
