Aluminum alloy hot top induction cooker casting technology is how to?Hot top electromagnetic casting method and the difference between ordinary electromagnetic casting process adopts special shield structure, and its internal made from refractory heat at the top end of liquid top solution forming, namely hot top with the function of the shield.Hot top electromagnetic casting technology has the following advantages:
1, compared with the electromagnetic casting technology, the heat have the function of the constraint of liquid forming.Metal level position control by contrast more easily, and is conducive to the stability of the liquid column height.
2, heat the top section is gradually increasing because of from bottom to top, in the process of casting metal burn note the amount of increase or decrease the effect of liquid column height is significantly weakened, so as to enhance the stability of the liquid column height and ingot casting size.
3, heat is advantageous to the liquid metal casting, reduces the impact of the water flow of metal liquid column.
4, due to the liquid - solid interface of liquid column still rely on the electromagnetic constraint to a state of suspension, guarantees the ingot casting side surface in the condition of free surface solidification, does not weaken the electromagnetic stirring effect of liquid cavity, inherited the electromagnetic casting ingot surface brightness and density of the internal organization.
Hot top electromagnetic casting technology which give full play to the advantages of the ordinary electromagnetic casting and electromagnetic casting and to enhance the operability of the system, and the magnetic field intensity and magnetic pressure distribution is reasonable, can effectively control the ingot casting inclusion and improve the quality of ingot casting surface and internal.
