The invention provides a fire
processing method for a thin-wall
quartz tube, and relates to the field of
quartz products. Comprising the following steps: S1, roughly
machining a tube body and a
flange of the
quartz tube, and reserving
machining allowance on the tube body; s2, finely burning the
pipe body and the
flange, annealing, cooling and cleaning; s3, the
pipe body and the
flange are fixed to the two sides of a
rotating disc machine correspondingly, a semicircular gun lamp is turned on, the to-be-bonded portions of the
pipe body and the flange are heated through flames, the
rotating disc machine is turned on at the same time, and the pipe body and the flange rotate at the same speed; after the to-be-bonded parts of the pipe body and the flange are heated to be bright and transparent, the pipe body makes contact with the flange, the semicircular gun lamp is turned off, and after cooling is conducted, the
rotating disc machine is turned off, and preliminary bonding is completed; s4, manually rotating the rotary disc machine, and heating by using a 3mm small gun until the bonding part of the workpiece is completely fused, so as to finish the bonding; and S5, the pipe body is machined, and the
machining allowance is removed. According to the machining method, firstly, the machining allowance is reserved at the fire machining part so as to increase the wall thickness of the pipe body, and the pipe body is prevented from deforming in the fire
machining process.
