回转筒体焊接工艺守则(国外英文资料) Welding procedure procedure for rotary tube 1 blanking Section 1.1 shall be made according to the drawing and workmanship. The material shall be checked, and the physical mark shall be in conformity with the drawing requirements. The size requirement of 1.3 is shown in table 1: unit (mm) size tolerance The diagonal tolerance Keep the balance in the machine ≦ 2500 Plus or minus 3 0 ~ 3 4 ≧ 2500 ~ 6000 0 ~ + 10 0 ~ 6 4 ~ 6 More than 6000 0 ~ + 10 0 ~ 6 4 ~ 6 Test method: measurement tools: a tape measure The line is marked in the section 1.4 section Cutting adopts manual, semi-automatic, automatic fire cutting machine. When the steel plate is thick delta 36mm, it must be left for 500 ~ 600mm to be used for molding. The welding groove adopts mechanical machining and carbon arc gouging, and the groove form is in the form of drawing and process requirement. 2 forming and assembling 2.1 cylinder section and the plate thickness of the plate are required to roll the two ends of the steel plate before it is rolled. Table 2: unit (mm) Tube mill Rotary kiln, single cold machine, dryer Belting leather paragraph Other paragraph ≦ 5 0.15% D ≦ 0.20% D Test method: measuring instrument: tape measure and measuring rod The angular E of the butt weld shall not be greater than 0.1 S + 1, the maximum shall not be greater than 3mm, and the length of the string shall not be greater than 300mm. 2.4 to the wrong side shall not be greater than 2mm. The wrong amount of the weld shall not be less than 600mm. Measure with a tape measure. The length of the seam edge of the seam is not less than 75mm. Measure with a tape measure. The 2.7-barrel assembly is assembled into the shipping segment, and the line is 5mm in line. To measure it with a drawing line. 3 welding It is automatic welding for the longitudinal and circular seam of the cylinder. The fillet welds can be soldered by manual arc. In open welding, it is not allowed to be soldered on rainy days and snowy days. When t
