Treating technology for ductile iron pipes after annealing

Abstract

The invention discloses a treating technology for ductile iron pipes after annealing. The treating technology comprises the following steps that a mapping table of a production line and relative positions of the on-line ductile iron pipes on the production line are preset in a computer control system; the mapping tablet records information, such as appearances, pipe diameters, ovality, wall thicknesses of the ductile iron pipes respectively, and number the ductile iron pipes respectively according to a sequence of the ductile iron pipes out of an annealing furnace; orders of the ductile iron pipes on the production line are set; the ductile iron pipes enter a first transportation line and a second transportation line in sequence after the annealing; the ductile iron pipes of which the diameters, the ovality, the wall thicknesses and the appearances are all qualified enter a subsequent finishing operation procedure; the ductile iron pipes with the unqualified ovality enter an ovality correction area; and the ductile iron pipes with the unqualified pipe diameters, wall thicknesses and appearances enter a waste pipe area. The treating technology is simple and precision in process; pipe sizes can be managed automatically; a quality control level of products can be raised; the traceability of the products can be improved; the efficiency can be improved; and the labor intensity of workers can be reduced.

Description

technical field [0001] The invention relates to a process for manufacturing pipes, in particular to a treatment process for ductile iron pipes after annealing. Background technique [0002] The current cast pipe process arrangement is that after the cast pipe is annealed, it is manually classified according to the specifications, and then manually sent to the subsequent production line according to the specifications or temporarily stored in the storage area according to the specifications, which cannot realize the automation of the entire process, and the entire process Time-consuming, manual measurement has low accuracy, low efficiency, and high labor intensity. Contents of the invention [0003] The object of the present invention is to provide a treatment process for ductile iron pipes after annealing. The process is simple and accurate, and can be completed automatically, so as to improve efficiency, reduce labor intensity of workers, and make product quality control ...
