Understand the production process of 304 stainless steel ball head!
The conical stainless steel head has exquisite quenching, smooth surface, acid resistance, alkali resistance and heat resistance, elegant appearance design and strong layering characteristics. The tapered stainless steel head looks like a spherical shape, so it is called a tapered stainless steel head. The production and processing method of spherical stainless steel head is high-precision CNC milling machine milling, usually CNC lathe boring, gas shielded welding and other production and processing of tapered stainless steel head application points: alloy Steel stainless steel head can crack under natural environment such as salt, ammonia, sodium partial alkali, etc. Please indicate to remove the remaining ground stress when purchasing stainless steel head. Stainless steel plates can cause stress corrosion cracks in the special natural environment with chloride ions. Please select suitable raw materials in the design concept. For carbon steel vessels that require hot dip galvanizing or aluminizing, please do quenching and tempering first.
stainless steel ball treatment, except for the remaining in-situ stress stainless steel head is the machine equipment of high-pressure vessel heating furnace. According to different requirements, there are specifications such as ball type, oval type, butterfly type and cone type. Regulations on production and processing of stainless steel heads: Before laser cutting edges of stainless steel heads, check whether their specifications are appropriate and review them when necessary. When laser cutting the edge of the stainless steel head, it is necessary to draw the line after the effect. And the standard line is vacated, and the laser cutting edge is cut according to the drawing line to prevent the welding seam of the oblique stainless steel head from being cut. There are also many materials used to produce the conical head according to the welding side, and carbon steel is more common, stainless steel plate and carbon steel.
crafts inspection. The cone-shaped head is applied, because it looks like a cone, and the ground stress of the plastic film is generated at the large end under the external pressure effect of a part of its main body. At the joint of the cone and the barrel, because of the discontinuity of the geometry, the radius of curvature has plummeted, so that there will be a large transverse thrust, resulting in a large edge stress, which is very easy to produce bending, therefore, it is required to improve. The big end method of conical head is used. The weld surface shall be polished and smooth, and non-destructive testing technology shall be carried out according to the provisions of the sample drawing. After the carbon steel stainless steel head is made, the sand blasting process should be carried out to eliminate the air oxide layer on the surface; Pickling and passivation shall be carried out on the surface of stainless steel head of stainless steel plate.
The surface of the stainless steel head should be prevented from bumping and scratching. During the whole process of heating and water cooling, the water cooling rate of the stainless steel head is different from that of the stainless steel head, the composition temperature difference will cause the volume to rise and reduce the unevenness and cause the stress, that is, the welding stress. Under the actual effect of welding stress, because the surface is less than the core at the beginning, the reduction also exceeds the core and then the core is pulled, when the water cooling is completed, because the main canal suspected of discharging sewage from Haixing County sewage treatment plant in the first-class protection zone of the production process of 304 stainless steel spherical head in Yiyang county behind the core only adopts temporary measures of blocking by piling soil. The reduction of water cooling volume cannot be carried out on its own and then the surface is pulled by the core. That is, under the actual effect of welding stress, the steel surface is finally stressed and the core is pulled. This kind of situation is harmed by factors such as water cooling rate, raw material composition and heat treatment method.
