Recently, the spinning workshop of Shandong Qilu Petrochemical Machinery Manufacturing Co., Ltd. has produced a titanium 304 composite plate (12+3) head with a diameter of 2500 mm and a wall thickness of 15 mm. It has been tested that the head has uniform thickness, hardness and accuracy. Within the standard range. The creation of the limit for the entire plate spinning of titanium composite panels this time broke the precedent that such materials cannot be formed by special materials experts, and became the first domestic enterprise to master the primary cold forming technology of high-strength, large-size reactor heads.
After receiving this task, the spinning workshop of Shandong Qilu Petrochemical Machinery Manufacturing Co., Ltd. immediately set up a research team to set up a special project for the special material composite plate head, formulate a detailed and thorough construction plan, and finally, with the joint efforts of relevant personnel in the workshop One spin was successful.
It is understood that domestic enterprises usually use hot press forming when processing large-size and thick plate heads. Due to uneven heating, steel structure changes, and large finished product size tolerances, product reliability and production efficiency are restricted. This technological breakthrough is conducive to improving production efficiency under the premise of ensuring higher processing accuracy in future production. At the same time, cold spinning has less impact on the structure of steel, and the pressure resistance and destructive resistance of the product in use are also better than Traditional processing methods.
