Problems solved by technology

[0010] Due to the adoption of step A, the shape and size of the steel mold cannot be made completely in accordance with the requirements of the optimized design drawings, and the production method can only be simplified, which has a certain adverse effect on the electrical parameters; due to the adoption of step E, the forced demoulding, It may cause deformation of the melting channel; due to the adoption of step F, the hole plugging part is likely to cause leakage during the work process, and it is actually shown that this defect often causes zinc leakage

Embodiment 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, the optimal technical parameters are determined, and the optimized molten channel drawing is designed.

[0027] Use strong and dry wood to make a mold (hollow) that fully meets the optimal technical parameters described in the previous paragraph, and then use superglue and bamboo pins to connect each section into a melt channel mold with a coherent cavity inside. The surface is brushed The insulating varnish is applied multiple times and baked repeatedly to form a layer of anti-seepage protective film on the surface of the wooden formwork to ensure no deformation and no water immersion.

[0028] Fix the mold inside the induction body wood case.

[0029] Fix the stainless steel sleeve 4.

[0030] Pouring refractory material.

[0031] After ...

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...
