Controlled cooling device for outlet side pipe body of steel pipe heat treatment furnace

Abstract

The invention relates to a steel pipe heat treatment furnace outlet side pipe body controlled cooling device, and belongs to the technical field of controlled cooling devices, the steel pipe heat treatment furnace outlet side pipe body controlled cooling device comprises a temperature control device, one side of the temperature control device is connected with a turbid circulating water pipeline through a pipeline, the pipeline is sequentially provided with a pipeline pump, a pneumatic butterfly valve and a pressure gauge, and the other side of the temperature control device is provided with a water drainage device; the temperature control device with the pneumatic butterfly valve for flow control is arranged on the outlet side of the normalizing furnace, the temperature control device adopts the annular eccentric spray seam assembly, a proper number of water jacket rings are selected to be combined and arranged according to the temperature control requirement, and the temperature control effect is good. The pipeline pump and the pneumatic butterfly valve are combined to control the water inlet flow and the pipeline pressure, rapid cooling and temperature control treatment is conducted on the heated pipe body on the outlet side of the heat treatment furnace, the purposes of improving the grain size of the pipe body and improving the mechanical property are achieved, and the strength of the pipe body and the stability of the mechanical property are improved.
