Materials generally include carbon manganese steel, stainless steel, zirconium, nickel base (Hastelloy, Monel, Inconel) alloy and other composite materials. The general understanding of reaction kettle is that stainless steel vessel with physical or chemical reaction is treated by second-hand reactor. Structural design and parameter configuration of vessel are carried out according to different process conditions. Design conditions, process, inspection, manufacturing and acceptance shall be in accordance with relevant technical standards. Jining second-hand reactor is used to realize heating, evaporation, cooling and low and high-speed mixing Response function
