6000升不銹鋼聚合釜的容积为6米~2,設計工作压力为12公斤/厘米~2,操作温度80～120℃。用于苯乙烯单体的聚合反应。整台設备由釜体、封头、夹套、攪拌軸、填料函和减速机等組成(见本期封面)。釜体及封头材料为1Cr18Ni9Ti钢,內徑1800毫米,壁厚16毫米,釜內要求抛光,焊縫須进行AM法晶間腐蝕試驗,制成后要求进行不少于24小时的气密性运轉試驗,平均每小时泄漏量不得超过0.25%。現将我厂对其中几个主要零部件的加工工艺介紹如下。
6000 liters stainless steel polymerization vessel volume of 6 m ~ 2, the design pressure of 12 kg / cm ~ 2, the operating temperature of 80 ~ 120 ℃. For the polymerization of styrene monomer. The entire device from the kettle body, head, jacket, mixing shaft, stuffing box and reducer, etc. (see this issue cover). Kettle body and head material 1Cr18Ni9Ti steel, inner diameter 1800 mm, wall thickness 16 mm, the kettle required polishing, the weld should be AM intergranular corrosion test, made after the request of not less than 24 hours of air tightness Running test, the average hourly leakage shall not exceed 0.25%. Now I plant of which several major components of the processing technology are as follows.
