Abstract
The utility model discloses a light annealing cooling device for a stainless steel welded pipe and solves the problems of the existing light annealing cooling device that the graphite powder adheres to the tubular product, affects the product quality and rusts the stainless steel welded pipe when in use, and the tubular product wears the graphite block to lower the production ratio and decrease the yield and have effects on the product quality. The device is provided with a cooling body with flanges at both ends, and is characterized in that the cooling body has a tubular shape and a ring-shaped cooling jacket is arranged in the cooling body; and graphite pipes are arranged in the cooling body; as the graphite pipes are adopted, the contact between the tubular product and the graphite pipe is non-rigid, the graphite powder can not drop off or adhere to the tubular product; besides, the cooling method is changed into radiation and convection method from the former heat conducting method, the cooling effect is good and the product quality is obviously improved; moreover, the tubular product has little wear to the graphite pipe, thus repair is not needed, the changing period is prolonged and only the graphite pipe close to the inlet end of the tubular product needs changing.
Description
Technical field
The utility model is particularly related to a kind of stainless steel welded pipe clean annealing refrigerating unit.
Background technology
Existing stainless steel welded pipe clean annealing refrigerating unit is a cooling body of establishing watercooling jacket by interior, the graphite block that radially is located on the cooling body constitutes, the problem of its existence is: 1, described graphite block leans on tubing by the holding device that is located on the cooling body, because graphite block closely contacts with tubing, Graphite Powder 99 is floating on tubing, influence quality product, make stainless steel welded pipe produce corrosion in use.2, tubing has wearing and tearing to graphite block, will shut down after use for some time graphite block is repaired, and will frequently regularly replace.Therefore, both influence production schedule, and caused the lumber recovery of tubing to descend again, increased production cost; 3, by holding device graphite block is held tightly tubing, after the spring in the holding device weakened, cooling performance descended, and influences quality product.
Summary of the invention
The purpose of this utility model is to solve the problems referred to above that prior art exists, and a kind of good product quality is provided, and production efficiency is good, the stainless steel welded pipe clean annealing refrigerating unit that production cost is low.
Technical solution of the present utility model is: it has two ends to be provided with the cooling body of flange, and its special character is: described cooling body is a tubulose, and is provided with the annular cooling water cover in cooling body, is placed with carbon tube in cooling body.
Above-mentioned stainless steel welded pipe clean annealing refrigerating unit, described carbon tube is divided into two sections, and near one section internal diameter of the tubing leading-out end internal diameter greater than another section, collides with carbon tube when preventing that tubing from causing.
The utility model has the advantages that: owing to adopt carbon tube, make and be non-rigid the contact between tubing and the carbon tube, the Graphite Powder 99 of carbon tube can not come off and float on tubing, and the type of cooling is changed into radiation, convection type by original thermal conductance mode, good cooling results, quality product obviously improves; Tubing is little to the carbon tube wearing and tearing, need not to repair, and has prolonged the replacement cycle, only need change the carbon tube near the tubing inlet end during replacing.
