Description

[0002] Electric crucible furnace is the simplest smelting equipment, mainly used to melt non-ferrous metals with low melting points, such as copper, aluminum and their alloys. In this furnace, the alloy is melted in the crucible, and the heat is transferred to the items in the pot through the crucible. The items in the crucible are not in contact with the external air, so the chemical composition of the alloy is almost unaffected by factors such as high temperature and air, and the temperature of the alloy liquid is also relatively uniform.

[0003] After searching, the announcement number is CN212902616U, which discloses a new type of tilting electric crucible furnace electric belt suspension structure, including a furnace body composed of multiple refractory bricks and an electric belt, a plurality of evenly distributed upper hook nails are embedded on the inner side of the furnace body, one end of the upper hook nail extends outside the furnace body and is provided with a bending portion, a plurality of evenly distributed conduits are embedded in the furnace body below the upper hook nail, and lower hook nails are slidably sleeved in the plurality of conduits.

[0004] In the process of realizing the utility model, the inventors found that at least the following problems exist in the prior art and have not been solved: the electric heating belt is installed between the upper hook nail and the lower hook nail, and then the bolt is rotated with a wrench. When the bolt is rotated under force, the lower hook nail is driven to rotate, and when the lower hook nail is rotated, the limiting rod is driven to rotate. When the limiting rod rotates to the lower dead point, the nut on the locking bolt is tightened, so that the limiting rod cooperates with the bent portion on the upper hook nail to suspend and install the electric heating belt. However, during installation and use, the sealing of the electric crucible furnace is easily destroyed, and the distance between the upper hook nail and the lower hook nail cannot be adjusted. Only one size of the electric heating belt can be limited and fixed, and the scope of use is limited.

[0005] Therefore, we propose a tilting electric crucible furnace electric heating belt suspension structure, which can solve the above problems. Utility Model Content

[0008] As an optional solution of the technical solution of the present application, there are two groups of connection blocks inside the connection groove, and the two groups of connection blocks are respectively placed on the upper and lower sides of the connection groove.
