In order to achieve the goal of building the first chemical large-scale non-standard equipment manufacturing base in Shanxi, Fengxi Group Chemical Equipment Co., Ltd., through independent research and development and joint research institutes, has overcome a number of technical difficulties. Among them, alumina evaporation equipment manufacturing technology has been highly evaluated by foreign experts.
The company and Northeastern University jointly digested and absorbed French technology, and produced the complete set of equipment for the evaporation section of the 1 million tons alumina project of Shanxi Luneng Yuanping. The company's first super-built 4.5-m-meter, 5100-m heat-exchange area and 150-ton-heavy domestic first super. Large tubular heat exchangers form a manufacturing technology with independent intellectual property rights.
In addition, the company also cooperated with Sichuan General Chemical Technology Co., Ltd. to solve the problems of forming, pairing, welding and heat treatment of the equivalent expansion coefficient of the 13MnMoNiNbR duplex stainless steel, and overcame the technical difficulties in the manufacture of the methanol synthesis tower; in conjunction with Tianliang Chemical Design Institute, Designed and developed key equipment such as heating furnace for coke oven gas to methanol, oxygen-enriched preheating furnace, etc.; meanwhile, it overcomes all-position CNC pulsed tungsten-arc welding technology for tubes/tubesheets, making the heat exchanger tubes and U-tubes. The automatic connection of the nozzle and the tube plate to achieve automatic argon arc welding. The development and application of these new technologies have increased the technical content of the equipment and have played a key role in further expanding the market and improving the competitiveness of enterprises.
