应釜的广义理解即有物理或化学反应的容器。反应釜材质一般有碳锰钢、不锈钢、锆、镍基（哈氏、蒙乃尔）合金及其它复合材料。可采用SUS304、SUS316L等不锈钢材料制造。不锈钢反应釜广泛应用于石油、化工、橡胶、农药、染料、医药、食品等生产型用户和各种科研实验项目的研究，用来完成水解、中和、结晶、蒸馏、蒸发、储存、氢化、烃化、聚合、缩合、加热混配、恒温反应等工艺过程的容器。

反应釜的材质一般有碳锰钢（内衬搪瓷）、不锈钢、锆、镍基合金及其它复合材料，广泛应用于石油、化工、橡胶、农药、染料、医药、食品等许多行业，反应釜的搅拌器有锚式、框式、桨式、涡轮式，刮板式，组合式等；密封装置可采用机械密封、填料密封等密封结构；反应釜的加热、冷却可采用夹套、盘管、米勒板等结构；加热与冷却方式有：蒸汽、电加热、导热油、水、冷冻盐水等，以满足耐酸、耐高温、耐磨损、抗腐蚀等不同工作环境的工艺需要。

The general understanding of the reactor is the container with physical  chemical reaction. Generally, the materials of the reactor are carbon manganese steel, stainless steel, zirconium, nickel base (Hastelloy, Monel) alloy  other composite materials. It can be made of SUS304, SUS316L  other stainless steel materials. Stainless steel reactor is widely used in petroleum, chemical, rubber, pesticide, dye, medicine, food  other production-oriented users  various scientific research  experimental projects. It is used to complete hydrolysis, neutralization, crystallization, distillation, evaporation, storage, hydrogenation, alkylation, polymerization, condensation, heating  mixing, constant temperature reaction  other technological processes.

Generally, the materials of reaction kettle are carbon manganese steel (lined with enamel), stainless steel, zirconium, nickel based alloy  other composite materials, which are widely used in many industries such as petroleum, chemical industry, rubber, pesticide, dye, medicine, food, etc. the agitators of reactor include anchor type, frame type, paddle type, turbine type, scraper type, combined type, etc.; the sealing device can adopt mechanical seal, packing seal, etc Sealing structure; jacket, coil, Miller plate  other structures can be used for heating  cooling of reaction kettle; heating  cooling methods include steam, electric heating, heat transfer oil, water, frozen brine, etc., to meet the process requirements of different working environments such as acid resistance, high temperature resistance, wear resistance  corrosion resistance.
