Abstract

The invention provides a cooling method and device for anticorrosion steel pipe manufacturing. The cooling method for anticorrosion steel pipe manufacturing includes the steps that after the first pipe end of a steel pipe enters a cooling region from an anticorrosion working region, a first internal cooling device moves in the axial direction of the steel pipe at the same speed as the steel pipe, a cooling nozzle arrives at the cooling working position and is opened, a belt-shaped telescopic mechanism moves towards the interior of the steel pipe at the same speed as the steel pipe as well, and the cooling nozzle is kept still; when the second pipe end of the steel pipe enters the cooling nozzle position, the cooling nozzle is closed, and the first internal cooling device returns to the initial position for use; and the first internal cooling device and a second internal cooling device alternately conduct interior cooling on steel pipes passing the cooling region continuously. The cooling device applying the cooling method comprises a transmission device, the first internal cooling device, the second internal cooling device and a control system. By means of the cooling method and device, the anticorrosion quality and cooling efficiency of the steel pipes are improved, and production cost is lowered.

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...
