Inspection of brazing furnace

2021-10

New items and contents for brazing furnace inspection, preliminary inspection, specifications and total quantity, leakage inspection of each pipeline, load current and motor grounding resistance of the circuit, accurate measurement of grounding resistance of electric heaters, and confirmation of conveyor belt operation inspection work ability of electric heaters. Raw materials and raw material tests required in the agreement on purchase of aluminum brazing furnace, attitude test of full flow spray equipment.
The final project acceptance of the new project of the high-temperature brazing furnace (in the buyer's processing plant), the appearance inspection of each brazing furnace equipment (no deformation, rust, paint loss, pipeline leakage), the test and evaluation of each equipment, the continuous spraying of tin equipment, the measurement of welding spray, drying equipment, the temperature control and temperature rise detection of up to 350 ℃, the commodity heating experiment confirmed that 180 ℃ and 200 ℃ can be kept for 0.5~1.5 minutes.
The maximum brazing temperature is 650 ℃, with a temperature error of+3 ℃ in the product temperature chart, and a temperature error of+5 ℃ in the furnace temperature. In the heating room, the temperature error is taken as the guarantee value for the soaking area of key products within the temperature range of 580-610 ℃. Accurate measurement of oxygen concentration in the furnace: braze the furnace core at 580-610 ℃ in the brazing furnace and measure the oxygen concentration.
Continuous brazing furnace production capacity and brazing characteristics, basic welding products and workpieces can be continuously welded for 8 hours and 3 times. Continuous brazing furnace production capacity: Check whether the production of products and workpieces is consistent or inferior to the agreement.
Surface cleanliness of the brazing furnace: without adhering all oil stains, with a fitting gap of 0.10 millimeters. Fixture: installed on the fixture of the product workpiece, even during thermal deformation, it is not easy to produce relaxation during the entire brazing process in the aluminum copper brazing furnace.
