A cooling method and cooling equipment for the manufacture of anti-corrosion steel pipes

Abstract

The invention provides a cooling method and cooling equipment for manufacturing anti-corrosion steel pipes. The cooling method for the manufacture of anti-corrosion steel pipes is as follows: when the first pipe end of the steel pipe advances from the anti-corrosion work area to the cooling area, the first internal cooling device moves along the steel pipe axis at the same speed, and the cooling nozzle reaches the cooling working position and starts, with The telescopic mechanism also moves to the inside of the steel pipe at the same speed, so that the cooling nozzle remains still; when the second pipe end of the steel pipe advances to the position of the cooling nozzle, the first internal cooling device returns to the initial position and waits; the first internal cooling device and The second internal cooling device alternately internally cools the steel pipes passing through the cooling zone continuously. The cooling equipment for implementing the above cooling method includes a transmission device, a first internal cooling device, a second internal cooling device and a control system. The cooling method and cooling equipment of the present invention realize uninterrupted internal cooling of the continuously produced anti-corrosion steel pipes, and improve the anti-corrosion quality and cooling efficiency of the steel pipes.

Description

technical field [0001] The invention belongs to the field of anticorrosion steel pipe manufacture, and relates to a cooling method and cooling equipment for anticorrosion steel pipe manufacture. Background technique [0002] The anti-corrosion steel pipe production line includes four main functional areas: pretreatment area, anti-corrosion operation area, cooling area and post-processing area. The cooling area is set next to the anti-corrosion operation area to cool the high-temperature anti-corrosion steel pipes connected end to end from the anti-corrosion operation area. [0003] The current anti-corrosion steel pipe production line mainly adopts external cooling method to cool the anti-corrosion layer and steel pipe. The outer layer of anti-corrosion layer is cooled first, and the inner layer of steel pipe is cooled later. If there are multiple layers of anti-corrosion layers, it is also cooled layer by layer from the outer layer to the inner layer. Due to the slow heat t...
