Description
Technical field
The utility model is related to local heating tooling in Field of Heat-treatment.
Background technology
In pressure vessel manufacturing processing industry, it is often necessary to carry out local heat treatmet to workpiece.Heat exchanger is with refinery
With the fast development of coal chemical industry, structure feature becomes increasingly complex, and the material of tube bank is not limited solely to stainless steel-like, low conjunction
Golden steel tube bank is more and more common, and the postwelding local heat treatmet of tube head part is that tube bank welding point stress is eliminated in manufacturing process
One of important measures.The common electrical heating method heater of high pressure heat exchanger low alloy steel beam tube head and thermal insulation material are fixed tired
Difficulty, complicated for operation, construction period is longer；Heater is bonded poor with tube sheet, and heat conduction efficiency is relatively low, and temperature gradient is larger, dissipates
Heat is big, and thermal effectiveness is poor, and capacity usage ratio is low.
Invention content
The purpose of this utility model is to overcome prior art defects, provide a kind of tube bank tube head electrical heating tooling, really
It protects heater effectively to heat, ensures thermal effectiveness.
A kind of tube head electrical heating tooling, structure have：Bottom plate 1, electric heater 3, thermal insulation material 4, panel 5, connects gusset 2
Connect wire guide 6 etc.；The bottom plate 1 is placed in construction site, supporting ＆ stablizing tooling；The gusset 2 is respectively welded in 5 both sides of panel,
Fixed panel 5 is in bottom plate 1；Electric heater 3 and thermal insulation material 4 are fixed on the panel 5, and connection is opened on thermal insulation material 4 and panel 5
Wire guide 6 is for connecting electric heater 3；3 center of electric heater can be effectively bonded with heat exchanger tube tube head.
A kind of tube head electrical heating tooling application method is as follows：
1. placing electrical heating tooling and tube bank on construction ground, adjustment tube bank center is with 3 center of tooling heater same
On horizontal plane；
2. requiring setting temperature measuring point, MT non-destructive testing points according to technology in tube sheet end face；
3. adjustment electrical heating tooling makes electric heater 3 be effectively bonded with the heat exchanger tube tube head heated；
4. can be put simultaneously using more than two heaters according to the needs of the heat exchanger tube tube head heated
Set its front and back or surrounding；
5. electrical heating tooling with by heating tube sheet outer rim use thermal insulation material auxiliary heat preservation；
6. electric heating control cabinet connection jaws are connect with electric heater 3 with power cord；
7. according to electrical heating regulation electrified regulation, heat treatment process is executed；
8. restraining tube head to complete after being heat-treated, electrical heating tooling is removed；Remove temperature measuring point and MT non-destructive testing points on tube sheet.
The beneficial effects of the utility model：Improve the thermal efficiency, it is ensured that tube bank tube head local heat treatmet quality；Operation
Simply, easy for installation, it improves work efficiency.
