Example Embodiment

[0025] Example 1

[0026] As shown in Figure 3, according to the specific conditions of the molten metal, the holographic numerical simulation and optimization of the heating and flow of the liquid metal in the molten channel are carried out on the computer to determine the optimal technical parameters, and then design the optimized molten channel drawing.

[0027] Use solid, dry wood to make a mold (hollow) that fully meets the optimal technical parameters described in the previous paragraph, and then use super glue and bamboo pins to connect the segments into a continuous cavity inside the mold as a whole, and the surface is brushed The insulating varnish is repeatedly baked and baked to form a layer of anti-seepage protective film on the surface of the wooden mold to ensure that it is not deformed or immersed in water.

[0028] Fix the mold in the wooden shell of the sensor body.

[0029] Fix the stainless steel sleeve 4.

[0030] Cast refractory materials.

[0031] After the r...

Abstract

The invention discloses a manufacturing method of a core-type induction furnace ring hearth. The method adopts wooden die and uses might bond and bamboo pin to connect the die sections into a ring hearth die with coherent cavity inside, before fixing the die inside the induction shell, with watertight treatment on the surface; after casting, refractory material dries out naturally. Use a resistance wire through the hollow wooden die, and blow clean by compression air and form ring hearth by gradually baking until the wooden die burnout, with electrifying and heating. The invention guarantees the ring hearth of no deformation, with the shape totally in accordance with theoretical design requirements and obtains pre-sintering ring hearth effect, with the advantages of no cracking, and long service life over two years, which is one year longer than steel ring hearth on average.

Description

technical field [0001] The invention relates to a method for preparing key components of non-ferrous metal smelting equipment, in particular to a method for manufacturing a melting channel of a cored induction furnace. Background technique [0002] At present, the power frequency cored induction furnace is one of the main equipments currently used in the melting or heat preservation of copper, aluminum, zinc and other non-ferrous metals and alloys. Its key component is the induction body. For the most widely used high-power jet type As far as the inductor is concerned, the most critical part is the melting channel, as shown in Figure 1. It has a steel shell 1, after the cavity melting channel 5 is formed in the refractory castable 2, the induction body is installed on the electric furnace body, the coil is energized after pouring liquid metal, and the induction body starts to work to heat the liquid metal. Because it directly determines the service life of the induction bod...
