Why does the medium frequency melting furnace have a dump design?
The inductor of the medium frequency diathermy furnace is designed according to the length of the heated workpiece and the diameter of the workpiece, so the inductor has lengths and shorts. But in general, the medium frequency diathermy inductor is generally relatively long (referring to the axial direction of the heated workpiece), and its purpose is to ensure that the heating temperature and the temperature difference between the core and the surface meet the requirements under the condition of the heating workpiece tempo unchanged.
There are basically two types of lining assembly for medium frequency heating inductors, one is knotted lining, and the other is assembled lining. Whether it is knotted lining or fabricated lining, long-term work under high temperature will change (mainly thermal expansion and contraction and oxidation). If used improperly, the heating material will collide and squeeze the furnace lining phenomenon, so the use of the furnace lining has a certain period of time.
Once the medium frequency induction heating furnace lining cracks, if it is a knotted lining, it must be filled with knotting material in time if the crack does not exceed 2mm. If the crack exceeds 2mm, the lining must be knotted again; if it is a fabricated lining, it must be replaced. Therefore, the user must take necessary measures based on the actual situation, and do not act hastily or even burn out the medium frequency heating sensor.
In daily life, precious metal materials are widely used. With the increase in consumer demand, people’s demand for gold, platinum, silver and other precious metal materials to make jewelry and watch products is also increasing. In the precious metal material manufacturing industry, to produce high-quality precious metal products, the smelting furnace is one of its important determinants.
Precious metal material smelting is to use an medium frequency melting furnace to smelt the precious metal material alloy in the presence of oxygen, and then melt it into a liquid for casting. Generally, the molten liquid is transferred to the mold manually. The existing medium frequency melting furnace is placed separately from the mold, and the manual transfer operation is inconvenient. In addition, the mold is placed on the platform, and it is necessary to manually suspend the crucible containing the molten liquid to transfer the liquid to the mold, which is inconvenient and dangerous to operate.
The medium frequency smelting furnace for smelting precious metal materials has been improved, and a dump-type medium frequency smelting furnace is designed to solve the above problems caused by smelting. The shell of the tilting medium frequency smelting furnace is provided with an accommodating groove for accommodating the platform, and the shell of the smelting furnace is provided with a push rod for driving the platform to turn back and forth, and a support for support is provided under the platform. The support includes a first extending vertically. A supporting arm and a second supporting arm extending in the left-right direction.
The first support arm is fixed on the left end of the second support arm, and the upper end of the first support arm is slidingly fitted with the bottom of the platform. The main body of the smelting furnace is provided with a telescopic groove for extending and retracting the second support arm in the left-right direction. After the smelting is completed, only need to push the push rod, you can easily pour the metal into the graphite tank to form. This design makes the smelting operation easier and more convenient for pouring.
The dumping design of the medium frequency smelting furnace solves the safety problem of precious metal jewelry production and is an important measure that fits the actual situation and meets the production needs.
