As the core equipment for material reactions in industries such as chemical, pharmaceutical, and food, the heating uniformity of stainless steel reaction vessels directly affects product quality, reaction efficiency, and production safety. When there is uneven heating in the reaction kettle, it may lead to local overheating of the material, an increase in reaction by-products, unstable product quality, and even equipment damage or safety accidents. Therefore, it is crucial to solve the problem of uneven heating in stainless steel reaction vessels.
