Seamless steel tube straightness has a great impact on precision machinery tubes and hydraulic cylinder tubes. Seamless Steel tube straightness precision improves customers' post-processing efficiency and reduces production costs. Seamless steel tube is the most afraid of buying seamless steel tube can not be processed, become waste, waste production costs and delay delivery, so choose a quality assurance manufacturer is very important.
1. Straightening equipment is backward
Backward straightening equipment, straightening accuracy is not good, seamless steel tube out after the straightness has not been greatly improved, can only do visual no bending. Such seamless steel tube straightness requirements for precision machining industry is not up to the requirements, such as hydraulic cylinder, for steel pipe straightness has a higher requirement, the need to maintain the consistency of the inner hole, if the straightening equipment is backward, is far from the requirements. We have advanced straightening equipment that can control seamless steel tube straightness to 0.5mm/m to meet the requirements of hydraulic cylinder production.
2. Seamless steel tube production process
Seamless steel tube is manufactured using two seamless steel tube processes: finish rolling and cold drawing. Generally speaking, the straightness of seamless steel tube after finishing rolling is better than that after cold drawing. Because finishing rolling is rolling, seamless steel tube will not have great elasticity. But in the process of cold drawing, seamless steel tube is stretched and has great elasticity. Plastic deformation occurs when seamless steel tube is removed from the drawing machine.
The above is seamless steel tube straightness factors have what answer, straightness for precision pipe is an important index, the better the straightness, the better the post-processing rate will be. For example, hydraulic cylinders, mechanical parts and other fields have higher requirements for seamless steel tube straightness.
