Embodiment 1
[0025] Put the preheated 748.3kg magnesium ingot into figure 1 The round crucible of the melting furnace is melted with flux. The amount of flux accounts for 4-7% of the total charge. During the melting process, a covering agent is sprinkled to prevent burning. The entire melting process is controlled within 3-6 hours, and the final temperature of the magnesium liquid is controlled at 670- 690°C. After melting, use a stirring device to add 11.6kg of zinc ingots and 6.7kg of manganese powder during the process of heating and stirring. At 720-750°C, use a feeding device to evenly add refining agent. The amount of refining agent accounts for 2-3% of the total furnace charge. Refining 40 -60min, after refining, use the slag extractor to clean the slag, then raise the temperature to 760-770°C, add 22.4kgMg-30%Nd, 12.50kgMg-30%Y with a colander, and blow and refine for 5-10min. The magnesium liquid is left to cool down to allow the flux and inclusions to settle. The whole process t...
Embodiment 2
[0027] Put the preheated 741kg magnesium ingot into figure 1 The round crucible of the melting furnace is melted with flux. The amount of flux accounts for 4-7% of the total charge. During the melting process, a covering agent is sprinkled to prevent burning. The entire melting process is controlled within 3-6 hours, and the final temperature of the magnesium liquid is controlled at 670- 690°C. After melting, use a stirring device to add 19.8kg zinc ingots and 11kg manganese powder during the process of heating and stirring. When the temperature is 720-750°C, use a feeding device to evenly add refining agent. The amount of refining agent accounts for 2-3% of the total furnace charge. After 60 minutes of refining, clean the slag with a slag extractor, then raise the temperature to 760-770°C, add 20.0kgMg-30%Nd, 14.50kgMg-30%Y with a colander, and refine by air blowing for 5-10min. The magnesium liquid is left to cool down to allow the flux and inclusions to settle. The whole p...
Embodiment 3
[0029]Put the preheated 734kg magnesium ingot into the round crucible of the melting furnace shown in Figure 1 and add flux to melt. The amount of flux accounts for 4-7% of the total charge, and the covering agent is sprinkled during the melting process to prevent burning. The entire melting process is controlled at 3- 6 hours, and the final temperature of the magnesium solution is controlled at 670-690°C. After melting, use a stirring device to add 15.2kg of zinc ingots and 6.5kg of manganese powder during the process of heating and stirring, and add refining agent evenly with a feeding device at 720-750°C. The amount of refining agent accounts for 2-3% of the total furnace charge. Refining 40 -60min, after refining, use the slag extractor to clean the slag, then raise the temperature to 760-770°C, add 22.0kgMg-30%Nd, 17.50kgMg-30%Y with a colander, and blow and refine for 5-10min. The magnesium liquid is left to cool down to allow the flux and inclusions to settle. The whole...
