Description

Technical Field

[0001] This utility model relates to the field of alloy production technology, specifically to an alloy production line for green calcium treatment. Background Technology

[0002] Green calcium treatment typically refers to the treatment of metallic materials (especially alloys) using environmentally friendly calcium-based materials (bio-calcium) or processes to improve their performance or reduce the environmental burden during production. In aluminum rod production, calcium-based alloys are added to achieve the purposes of deoxidation, desulfurization, grain refinement, and reduction of impurities.

[0003] In the aluminum rod production process, aluminum raw materials and additives are generally added to a furnace for melting. After melting, impurities in the molten aluminum float to the surface and need to be skimmed off manually with tools to improve the purity of the molten aluminum. However, the molten aluminum is prone to splashing during melting, and manual skimming with tools poses a high risk and certain safety hazards. Utility Model Content

A slag-skimming port 6 is opened on the outside of the furnace 1, and the slag-skimming port 6 is aligned with the skimming component 2.

[0019] The skimming assembly 2 includes a support frame 21 and a skimming plate 22. The support frame 21 is movably disposed on the outside of the furnace 1. The skimming plate 22 is inclined and movably engaged within the skimming port 6. Symmetrically distributed racks 23 are movably passed through the outside of the support frame 21. One end of each rack 23 is fixedly connected to one side of the skimming plate 22. A gear 24 meshes with the opposite side of the rack 23. A rotating shaft 25 is fixedly passed through the middle of the gear 24. A reduction motor 26 is disposed above the gear 24. The end of the output shaft of the reduction motor 26 is fixedly connected to one end of one of the rotating shafts 25. The reduction motor 26 can drive the rotating shaft 25 to rotate, which in turn drives the gear 24 to rotate. The gear 24 can then drive the rack 23 to move, causing the skimming plate 22 to move in and out of the furnace 1, thus facilitating the discharge of impurities. A fixing plate 27 is fixedly provided on the side of the 21 near the gear 24. The geared motor 26 is fixedly installed on the fixing plate 27. The fixing plate 27 makes it easy to install the geared motor 26. A limiting plate 28 is fixedly provided at the end of the two racks 23 away from the support frame 21. The limiting plate 28 can prevent the racks 23 from disengaging from the support frame 21. The two gears 24 mesh with each other, which can facilitate the transmission between the two gears 24. A guide chute 5 is fixedly provided on the side of the furnace 1 near the slag skimming port 6. The guide chute 5 is located below the slag skimming port 6. The guide chute 5 can guide the discharged waste slag and impurities. A drain valve 8 is installed at the bottom of the furnace 1. The drain valve 8 is aligned with the flow channel 3.

The inner sides of the flow channel 3 and the guide chute 5 are coated with an anti-stick coating.

[0020] The adjusting assembly 4 includes adjusting frames 41, which are symmetrically distributed and fixedly installed on the outside of the furnace 1. The two ends of the support frame 21 are located inside the two adjusting frames 41 respectively. Adjusting blocks 42 are slidably disposed inside the adjusting frames 41, with one side of each adjusting block 42 fixedly connected to the outside of the support frame 21. A guide groove 43 is provided on the outside of the adjusting frames 41, and a guide block 44 is slidably disposed inside the guide groove 43. The opposite side of each guide block 44 is fixedly connected to the outside of the adjusting block 42. A cylinder 45 is fixedly disposed at the top of the adjusting frames 41. The cylinder 45 is driven... The end is fixedly connected to the upper surface of the adjusting block 42. The driving end of the cylinder 45 drives the adjusting block 42 to move downward. The guide block 44 keeps the adjusting block 42 moving stably in the guide groove 43. The adjusting block 42 drives the support frame 21 to move, which in turn drives the skimming plate 22 to move downward, so that the lower side of the skimming plate 22 moves into the liquid surface of the solution, thereby facilitating the control of the skimming plate 22. A guide rod 46 is fixedly provided inside the guide groove 43. One end of the guide rod 46 moves through the guide block 44. The guide rod 46 can keep the guide block 44 moving stably.

[0021] Working principle: First, aluminum raw materials (aluminum ingots or recycled aluminum) are added to furnace 1 to melt the aluminum raw materials. After the aluminum raw materials are melted, alloying elements such as silicon and copper are added, followed by refining and stirring with bio-calcium. This allows the calcium to react with oxygen in the molten metal to form calcium sulfide (CaO) or calcium aluminate (CaAl2O4), reducing the oxygen content. Calcium also reacts with sulfur to form calcium sulfide (CaS), reducing sulfide inclusions. Calcium adsorbs hydrogen (H2) in the melt, reducing porosity defects. Subsequently, argon gas is introduced to stir the melt, promoting the floating of impurities. Next, the geared motor 26 is started, causing it to operate. The output of the geared motor 26 drives the rotating shaft 25 to rotate, which in turn drives the gear 24 to rotate. Through meshing, the two gears 24 rotate in opposite directions. The gear 24 drives the rack 23 to move towards furnace 1, and the rack 23 moves the skimming plate 22 into furnace 1. Inside, cylinder 45 is activated, causing it to start working. The drive end of cylinder 45 moves the adjusting block 42 downward, and the adjusting block 42 is kept stable in the guide groove 43 by the guide block 44. The adjusting block 42 moves the support frame 21, which in turn moves the skimming plate 22 downward, so that the lower side of the skimming plate 22 moves into the liquid surface of the melt. Then, the reduction motor 26 is activated to reverse and drive the skimming plate 22 to move in the opposite direction, so that the skimming plate 22 scrapes the impurities floating on the melt and moves them. The lower side of the skimming plate 22 is in contact with the inner side of the furnace 1. Then, cylinder 45 is activated to control the skimming plate 22 to move upward, so that the skimming plate 22 moves the impurities to the slag outlet 6 and falls from the slag outlet 6 into the guide trough 5. Then, the drain valve 8 is opened, and the melt is discharged from the furnace 1 into the flow channel 3 and flows into the mold of the casting device 7 to cast the melt. Finally, the aluminum rod is taken out by the hoisting equipment.
