Detailed Description
Example 1
The utility model provides a centreless response aluminium melting furnace inductor, includes inductor and the crucible that is arranged in the inductor, the drain pipe of crucible is located the lower part, and the inductor has four circles at the drain pipe department at least, and two circles that are located liquid outlet upper portion constitute two ascending arcs with the copper pipe of the same radius with the circle, and two circles that are located liquid outlet lower part constitute two ascending arcs with the copper pipe of the same radius with the circle, and the both ends of every arc correspond respective turn and connect.
The radius of the inner opening at the joint of the liquid outlet pipe and the crucible is larger than that of the liquid outlet pipe.
The ratio of the radius of the inductor to the radius of the liquid outlet is 1: 9-10.
The ratio of the effective induction height of the inductor to the radius of the liquid outlet is 1: 25-29.
The number of turns of the inductor is 30-40 turns.
Example 2
As shown in fig. 1, as a specific design of example 1, the diameter of the inductor 1 is 980mm, the effective induction height is 1350mm, the number of turns is 33 turns, and the power distribution source is 500 KVA. Crucible 2 is located inductor 1, designs drain pipe 3 below crucible 2, corresponds design arc return bend 4 on the inductor 1.
The inductor is different from the inductor of the conventional coreless induction furnace in that:
the liquid outlet of the prior crucible at the top is moved to the lower part, which seems to be a simple design, but increases the design difficulty. How to design the lower outlet in the core content of the device is to design a liquid outlet pipe at the lower part of a crucible, wherein the inner diameter of the liquid outlet pipe and the interface of the crucible is set to be 200mm, the diameter of the liquid outlet is set to be 100mm, then four turns of an inductor at the liquid outlet pipe are respectively disconnected from the center of the liquid outlet to the positions 100mm away from the center of the liquid outlet, then copper pipes which are the same as the turns are bent into arcs and respectively connected, the upper two turns of connecting arc copper pipes face upwards, the lower two turns of arc copper pipes face downwards, and the radius of the inner opening at the connecting part of the liquid outlet pipe and the crucible is twice of. The design can prevent the liquid outlet from solidifying when the liquid outlet produces the aluminum liquid, the machine can be not stopped when the liquid outlet produces the aluminum liquid, the liquid outlet generates the induction heating, the product percent of pass is greatly improved, and the problems in the prior art are thoroughly solved.
The above description is only for the specific embodiments of the present invention, and not limited thereto, and any person skilled in the art can easily conceive of the changes or substitutions within the technical scope of the present invention, and all the changes or substitutions should be covered within the protection scope of the present invention.
