Description
[technical field]
The invention belongs to the electrovacuum technology field and specially refer to the turning process of a kind of electrovacuum with glass.
[background technology]
A kind of unformed shape by the fusion object obtains through cooling is called vitreous state, and it is a kind of state of material outwardness, is similar to gaseous state, liquid state, crystallization etc.Glass belongs to the material of this class " vitreous state " exactly, and it is that various oxide compound heating and meltings become melt, obtains through overcooling again.
The development of electron tube once generally adopted glass as insulating material in the pipe shell-and-tube in early days, and at present, the electrovacuum ceramics that performance is more good has replaced glass in a large number, particularly is used widely in the microwave tube at electron tube.But because glass has the advantage of himself, it is at electron tube, especially still have a wide range of applications in display device, the photoelectric device etc., even in microwave tube, the also still a spot of output window that is used as some pipe of glass, the resonant window of discharge tube etc.
In the course of processing of traditional electron tube, all be to adopt diamond cutter to cut and grinding with the glass component.Along with the development of technology, the function of glass component is more and more, and shape becomes increasingly complex, and needs the amount of processing also more and more.With diamond cutter cost height, working (machining) efficiency is also low.
[summary of the invention]

[embodiment]
1, the electrovacuum annealing process of glass material:
In traditional glass processing, bursting that the glass internal stress causes is the not high one of the main reasons of passing rate of processing.Glass all can cause stress in heating, cooling and the course of processing.In order to eliminate this stress, must carry out anneal.So-called annealing reheats glasswork to conversion temp exactly, insulation for some time, and then slowly be cooled to normal temperature.The conversion temp of glass is meant the minimum temperature that the glass solid-state properties disappears, and being commonly defined as viscosity is 10
13Pool (1 pool=1 dyne. second/centimetre
2) temperature be conversion temp.This temperature can be found in the material behavior of producer, and each producer all is not quite similar.
The ANNEALING OF GLASS standard of the present invention regulation is, glass heats is high about 5 ℃ to the conversion temp that provides than producer, and insulation 30min cools to room temperature then with the furnace, do not allow to adopt form such as forced air cooling to improve its rate of cooling in process of cooling.
