Embodiment 1
[0017] The present embodiment adopts the 150KW intermediate frequency induction furnace with a melting capacity of 170 kilograms, and the specific process is as follows:
[0018] Step 1: Batching: Use No. 1 electrolytic copper, No. 1 electrolytic aluminum, No. 1 electrolytic nickel, and iron sheet for batching in a full furnace. After calculation, the mass percentage of each element in the batching is required to be: Al, 9.5%, Ni, 5.0%, Fe .
[0019] Step 2: Furnace installation: Check that the equipment of the 150KW intermediate frequency induction furnace is qualified, put all the No. 1 electrolytic nickel blocks into the bottom of the crucible of the induction furnace, insert the No. 1 electrolytic copper plate along the vertical direction of the crucible wall, and insert the iron sheet into the gap of the copper plate. The iron sheet placement method can help the iron sheet melt; The aluminum bronze refining agent is evenly sprinkled into the crucible, and N is 5; the re...
Embodiment 2
[0025] The present embodiment adopts the 150KW intermediate frequency induction furnace with a melting capacity of 160 kilograms, and the specific process is:
[0026] Step 1: Batching: Use No. 1 electrolytic copper, No. 1 electrolytic aluminum, No. 1 electrolytic nickel, iron sheet and the same grade of recycled material with clear chemical composition for full furnace batching. The quality of the recycled material is 30% of the total mass of the batching. After calculation The mass percent of each element in the required ingredients is: Al, 9.5%, Ni, 5.0%, Fe, 5.0%, Cu, the balance; the quality of the selected aluminum bronze refining agent with the characteristic of not increasing silicon is 0.4% of the total mass of the ingredients .
[0027] Step 2: Furnace installation: Check that the equipment of the 150KW intermediate frequency induction furnace is qualified, put all the No. 1 electrolytic nickel blocks into the bottom of the crucible of the induction furnace, insert t...
Embodiment 3
[0033] The present embodiment adopts the 150KW intermediate frequency induction furnace with a melting capacity of 150 kilograms, and the specific process is:
[0034] Step 1: Batching: Use No. 1 electrolytic copper, No. 1 electrolytic aluminum, No. 1 electrolytic nickel, iron sheet, and the same grade of recycled material with clear chemical composition for full furnace batching. The quality of the recycled material is 40% of the total mass of ingredients. After calculation The mass percent of each element in the required batching through calculation is: Al, 9.5%, Ni, 5.0%, Fe, 5.0%, Cu, the balance; 0.5%.
[0035] Step 2: Furnace installation: Check that the equipment of the 150KW intermediate frequency induction furnace is qualified, put all the No. 1 electrolytic nickel blocks into the bottom of the crucible of the induction furnace, insert the No. 1 electrolytic copper plate along the vertical direction of the crucible wall, and insert the iron sheet into the gap of the c...
