Embodiment Construction

[0051] Below in conjunction with accompanying drawing, the present invention is further described;

[0052] A processing technology for a W-shaped regenerative radiant tube, characterized in that the processing steps are as follows: straight tube casting - elbow casting - straight tube and elbow welding to assemble into a W-shaped tube body - convex flange production - panel production - Furnace wall bracket production - flat flange production - radiant tube finished product.

[0053] Described straight pipe casting comprises the following steps to form,

[0054] 1) According to the requirements of the design drawing of the pipe body, the mold is designed and made of 25CrMo or 35CrMo mold steel.

[0055] 2) Mold inspection, check inner hole size, roughness, coaxiality, roundness, straightness, wall thickness, etc.

[0056] 3) Casting, using the centrifugal casting method to cast the pipe body, and the casting temperature is controlled at 1450°C-1500°C;

[0057] 4) Capillary...

Abstract

The invention discloses a processing technology for a W-shaped heat accumulation type radiation pipe. The processing technology is characterized by comprising the following processing steps: casting a straight pipe, casting an elbow, welding the straight pipe and the elbow to assemble a W-shaped pipe body, preparing a male flange, preparing a panel, preparing a furnace wall bracket, preparing a flat flange and preparing a radiation pipe finished product.

Description

technical field [0001] The invention relates to the field of radiant tube manufacturing and processing, in particular to a processing technology of a W-shaped regenerative radiant tube. Background technique [0002] In the production of cold-rolled steel strip, the steel strip after cold deformation should be heated above the recrystallization temperature in the heating furnace, so that the deformed grains can be re-transformed into uniform equiaxed grains, so as to eliminate the cold-rolled steel strip. Deformation hardening and residual stresses. In order to meet the increasingly higher requirements for the surface quality of strip steel, most modern continuous annealing furnaces for strip steel use radiant tube heating furnaces. Using this heating method, the combustion gas does not directly contact the strip steel, and will not oxidize the surface of the strip steel, and the nitrogen-hydrogen mixed protective gas is also used in the furnace, which has a certain reducing...
