The enameled ladle must be pre-baked at a certain temperature, and the paint can be dried after being dried in the shade for 24 hours. Oil furnace (1) Check the condition of the oil furnace crucible before use, replace the crucible in time, and the new crucible should be preheated; (2)
Check whether the oil nozzle is faulty and the incineration channel is blocked before incineration. . The upper limit is 10% and 2%. There are coke-like sinters, it is necessary to clean up; (3) When replacing the crucible, make sure that the bottom of the crucible is flush with the upper edge of the atomizing nozzle; (4) The oil inlet switch of the oil furnace should be small and then large, and gradually adjusted to ensure sufficient fuel Incinerate. 2.
The runners are returned to the furnace on site, and the waste parts require clean oil pollution.3%~0.5% of the furnace weight; the dosage of each flux must meet the specifications to avoid affecting the mechanical function and various components of the alloy.12 24.00 95.23 Fe 3 2% 0. Preparation of master alloy 103 master alloy (AlFe alloy) smelting technology, according to the share of 103 plus two burns, and then enter the furnace for smelting. Preparation of raw materials and return materials.
Centrifugal casting machine (1) Before pouring, check whether the circuit of the centrifugal casting machine, maintenance shell, cover plate, mold fixture, Copper tape for disconnect connection etc. Taking into account the secondary smelting, the theoretical burning loss of aluminum and iron should be preset at 16% and 4%, that is, the amount that should be used when smelting master alloys is shown in Table 1.00 12. The theoretical burning loss of Al is 4%-10%, and the theoretical burning loss of Fe is 1-2%. Pouring equipment I. 4.06 3. Things (1) Melting things, such as steel drills, sample spoons, slag spoons, mixing griddles, charging tongs, bell jars, etc. Table 1. II. Smelting equipment I
