大型圆筒混合机筒体施工制造过程(国外英文资料) Large cylinder mixing machine construction process Structural features and technical key The cylinder is the most important and critical component of the whole mixer. This single weighing one hundred tons, the largest cylinder diameter 5.1 m, the largest barrel length up to 30 m, with enough rigidity large cylinder, is by the inner diameter of different wall thickness, such as paragraph of section tube compound structure. The accuracy of the coaxial precision is the most basic technical condition for the negative loading and running stability of the cylinder. The radial round and the end of the disc of the donut of the donut of the large toothed ring are guaranteed to have a high mesh accuracy. Especially the retainer cylinder, big gear ring, cylinder liner board accessories such as a complete set of unit weight and mix blend dynamic impact load rolling circle roundness, alignment accuracy is sure the basis of the mixing machine running smoothly. These technologies are the key to ensure the quality of the products in the manufacturing process. And in order to ensure the simplified strength and service life, avoid internal cylinder weld defects and completely eliminate the welding stress in full, the same shall be of particular concern is in manufacturing process manufacturing. Unit 2 assembly manufacturing Cylinder is forged from two pieces of wall thickness of 280 ~ 320 mm roller ring and 55 ~ 65 mm, 40 ~ 45 m m, 30 ~ 36 mm, 22 ~ 24 mm thick as well as more than a combination of inner diameter tube section welding form structure. It is based on the characteristics of this composite structure that determines its staging and welding combination. Section 2.1 tube welding technology measures of shell welding construction quality for simplified strength, service life and the importance of the overall accuracy is directly related to, so to take strict construction measures as follows: (1) comprehensive consideration should be taken into considera
