There are three types of stainless steel, ferritic stainless steel and martensitic stainless steel with chromium as the main alloying element. There are also austenitic stainless steels with Cr-Ni as the main alloy. Chromium and nickel are all alloy elements that can expand the austenitic phase zone. When nickel is added to steel containing more than 18% chromium, single-phase austenitic steel can be obtained at room temperature. If quenched at 1050~1100 degrees C, the sub-single-phase austenitic structure can be obtained with 8% nickel content, which is our most commonly used Cr18Ni8 series stainless steel.

The R&D content of DEAR Air Separation Argon Recovery Project includes: the selection of process routes, and the selection of more reasonable and effective process routes through comparison; Design of equipment parameters: design the drawings of individual equipment according to the route and equipment parameters provided by the process; The overall design is to connect all equipment into a system through pipelines to achieve the goal of process route. After the completion of the project, it can be put into experiment and operation, achieve the goal of continuous argon production, and continuously save the use cost of liquid argon for customers. If there is other need, you can copy this product or improve the design on the original basis. Meet the customized needs of users.

DEAR air separation adopts the "software and hardware integration" scheme to implement the energy-saving transformation of air separation. Under normal conditions, the transformation can reduce the power consumption by about 15%. The cooperation supports the EMC (energy management contract) mode. The customer does not need to invest in advance, and the two sides share the saved electricity revenue.

In terms of technology, different from most manufacturers that only guarantee the output of oxygen and nitrogen, Deere realizes the full extraction of oxygen, nitrogen, argon, helium, neon, krypton and xenon, and the output and purity of various products meet or exceed the contract indicators, so as to fully tap the value of Air Resources. In terms of delivery, the integrated mode reduces the connection problems caused by multi-party subcontracting, shortens the construction cycle, helps customers put into production quickly, and shortens the return on investment cycle. The system energy consumption is stable and meets the contract design standard, and the problem of "paper energy saving, actual high consumption" is eliminated. Intelligence is a highlight. The project applies Deere's self-developed blue bank intelligent operation and maintenance system for the first time, relying on big data, AI model, robot and UAV inspection, to realize real-time monitoring, intelligent analysis and
