Embodiment Construction
[0038] refer to figure 1 A method for guiding the smelting process by measuring the relative carbon content in a solid sample of aluminum-silicon alloy smelted by electrothermal method, comprising the steps of:
[0039] (1) A quartz tube 1 with a diameter of 50 mm, the front end of the quartz tube 1 is a capillary joint 5, and the length of the capillary joint 5 is 40 mm; Out of electric furnace 200mm;
[0040] (2) heating the tubular electric furnace 2 into three temperature zones of 800°C, 1000°C, and 1100°C and keeping it stable;
[0041] (3) The porcelain boat 3 was calcined to a constant weight at 1100°C, and the sample 4 to be tested was dried to a constant weight at 110°C with a moisture analyzer;
[0042] (4) Inert gas argon is passed through a piston at the rear end of the quartz tube 1, and a pressure reducing valve is used to adjust the gas delivery rate so that the gas intake is constant during the whole process;
[0043] (5) Put the sample 4 into the porcelain ...
