It is easy to crack, production requirement can be met well.
In order to achieve the above objectives, the technical solution adopted by the present invention is that:
The present invention provides a kind of butt-joint process of heavy caliber quartz ampoule, for docking after the quartz ampoule melting by two major diameters
Fixed, butt-joint process includes following procedure of processing:
Facade pretreatment, polishes to two faces that two quartz ampoules connect, so that becoming substantially smooth radial section；
Pre- thermal conditioning, the burners set small fire for fused quartz tube preheat 2 ~ 3min, until each blowtorch inner hole in burners set
Aqueous vapor, which is parched into burning, melts process；
Heating, which is burnt, melts, and adjusts the position of each lamp cap in burners set, so that lamp cap is directed toward quartz ampoule to be processed, improves and enters spray
The hydrogen-oxygen throughput of lamp group is warming up to quartz ampoule color and bleaches until the radial section vaporization dazzling, quartz ampoule is to be docked is smoldered
Afterwards, two quartz ampoules are docked, and 25 ~ 30min of continuous heating；
Docking is clapped, and continues the hydrogen-oxygen throughput for keeping burners set after the docking of two quartz ampoules, while contacting stone using resistance to hot wafering
The interface of English pipe realizes the pressing to quartzy tube outer surface；
Heat preservation, gradually reduces hydrogen-oxygen throughput, and entire temperature-fall period continues 10 ~ 15min, not dazzling and hair at band quartz ampoule docking
It shuts down, stop the supple of gas or steam when white；
Cooling, is wrapped at the docking of quartz ampoule, temperature fall time is removed from machining tool after continuing 30 ~ 40min with silica wool
Quartz ampoule；
Cooling, the quartz ampoule removed is placed in stuffy place, when the temperature of quartzy joint is down to naked hand and be can contact
It sends to laundry, and then finished product.
For above-mentioned technical proposal, there are also further Optimized Measures by applicant.
Further, in pre- thermal conditioning, the aqueous vapor of blowtorch inner hole blocks the stone of docking respectively using silica wool after parching
The both ends of English pipe are burnt subsequently into heating melts process, and removes the silica wool after cooling, cooling process and send to laundry again.
Further, when entering cooling process, the temperature at docking just can remove both ends when reaching 40 degree or less
Silica wool.
Further, when being cooled down, using graphite cushion block pad in the lower section of quartz ampoule, so that the docking of quartz ampoule
Place's suspension.
It further, include multiple blowtorch in the burners set, multiple blowtorch are arranged in same perpendicular and entirety
Setting annular in shape, and the lamp cap of blowtorch is directed toward its center, and quartz ampoule is right through the center.
Due to the above technical solutions, the present invention has the following advantages over the prior art:
The butt-joint process of heavy caliber quartz ampoule of the invention can guarantee two by the monitoring and regulation for heated condition
Being reliably welded and fixed in quartz ampoule docking operation, stabilized structure, while rate of temperature fall can be effectively controlled in cooling procedure, prevent
Only the problem of rapid cooling brought Local Cracking, the yields of product is improved, reduces production cost.
