Heating furnace bottom vaporization cooling pipeline lower support device

Abstract

A heating furnace bottom vaporization cooling pipeline lower support device comprises a fixing base and an adjusting assembly. A spring is arranged in the fixing base, one end of the spring abuts against the bottom wall of an assembling groove, and the other end of the spring is provided with a check ring sleeve. The adjusting assembly comprises an adjusting screw, one end of the adjusting screw is adjustably connected with the top face of the check ring sleeve, a bracket is arranged at the other end of the adjusting screw, the upper side face of the bracket is a bearing face used for making contact with a pipeline, the bearing face is of a V-shaped face structure, and the bracket is of a hollow structure. The heating furnace bottom vaporization cooling pipeline lower support device has the beneficial effects that the structure is simple, and usage is convenient; the heating furnace bottom vaporization cooling pipeline lower support device can solve the problem that when a pipeline expands due to heat and shrinks due to cold and inner stress is generated, a pipeline support structure is likely to cause pipeline stress accumulation, and structure damage (fatigue crack) is likely tohappen; due to usage of the heating furnace bottom vaporization cooling pipeline lower support device, the water leakage accident can be effectively prevented; the heating furnace bottom vaporizationcooling pipeline lower support device has the functions of heat isolation, buffering and vibration absorbing; and a V-shaped structure is adopted on the top face of the bracket, pipeline positioning is accurate, and the pipeline arrangement stability degree can be improved.

Description

technical field [0001] The present invention relates to the technical field of heating furnaces and related equipment, and more specifically, relates to a lower support device for vaporization cooling pipelines at the bottom of a heating furnace. Background technique [0002] At present, during the operation of the furnace bottom vaporization cooling pipeline in the steel rolling heating furnace, the pipeline will produce normal thermal displacement to a certain extent, and the pipeline will also produce vibration and swing at a certain frequency and amplitude, which will affect the cooling pipeline. The installation puts forward higher technical requirements. [0003] In the prior art, when arranging the pipeline support, if the pipeline is fixed by a rigid support, once the above situation occurs in the pipeline, internal stress will be generated, and the accumulation of internal stress will cause fatigue and cracks in the pipeline, seriously This can lead to water leakag...
