The specific embodiment
Embodiment is an example with practical operation of the present invention.Its operation principle is: the guipure by guipure transmission device 1 is sent to body of heater 5 (brazing area) with mother metal from feeding platform 3 (feeding area) and carries out soldering, after water jacket 6 (cooling zone) cooling, exports from discharge pedestal 7 (discharge zone); Feed gas after liquefied ammonia decomposes in the body of heater as protection gas, prevent and avoid workpiece in heating, brazing process, oxidation to take place, guarantee brazing quality.
Network bringing type brazing furnace must carry out baker before back or idle half a year of above use are installed, and removes the moisture content in the body of heater, improve insulating properties, make furnace lining 51 mortar joint sintering, increase furnace lining structure intensity, the furnace lining minimizing in use causes the refractory material cracking because of heating up rapidly and damages behind baker.
The furnace drying time table
The valve of the jacket water of fetching boiling water turnover, control flow of inlet water size.Open the heating furnace body switch of electric control cabinet, set and regulate the control temperature parameter, regulate converter parameter, open running guipure transmission device.During normal the use, beginning is carried out according to following heat temperature raising step: be warming up to 300 ℃ of insulations 30 minutes, be warming up to 600 ℃ of insulations 30 minutes then, be warming up to 850 ℃ of insulations 60 minutes again, rise to temperature required then.The stage temperature that heats up when can reduce flue 54 heating is uneven and be out of shape, and the length percentage elongation prevents that with certain buffering the furnace temperature intensification is too fast when heat to flue, and the surface temperature that causes heating element heater 55 is too high and damage.Use intensification to reach 650 ℃ at body of heater, elder generation feeds nitrogen, after treating to have driven air in the flue, feeds hydrogen, nitrogen, assurance flow when logical hydrogen, nitrogen, and pipeline is answered unimpeded must not dying; As hydrogen takes place die, connect the nitrogen air supply system fast.When being cooled to 650 ℃ after the use, by fill hydrogen, nitrogen changes nitrogen into, the inflated with nitrogen time can stop after being about 15 minutes.Furnace temperature must not cut off the water supply more than 300 ℃, and the water temperature of cooling water is about 40 ℃.
Control brazing area of the present invention is realized stepless voltage regulation, guarantee the interior temperature constant of flue of heating rear furnace body, temperature stability reaches ± and 1 ℃, when mother metal was carried out soldering, the soldering position was accurate, the efficient height, solder is evenly filled, the mother metal distortion is little, and welding point is smooth smooth, has effectively guaranteed dimensional accuracy, quality and the outward appearance of brazing product.For safe operation, body of heater is provided with that hydraulic pressure is under-voltage, ammonia is under-voltage, divide protective device such as under-voltage, the overtemperature alarm of venting one's spleen, the continuous and automatic operation, and operating efficiency improves more than the thirtyfold than the traditional vacuum soldering oven.The size of flue manufactures and designs according to the specification and the output of user's different product in the body of heater, and specificity and versatility are all stronger.
