Problems solved by technology

[0002] At present, the magnetic strips of electromagnetic induction heating coils sold in the market are all made of ferrite, and ferrite can be divided into two types: manganese-zinc system and nickel-zinc system. For more than 20 hours, the temperature of the furnace needs to be as high as 1000°C during sintering, which consumes a lot of power, and will cause a lot of powder during production, which will pollute the environment and is listed as a polluting enterprise prohibited by many local governments.

Abstract

The invention discloses a method for manufacturing a magnetic stripe of an induction cooker. The method comprises the following steps: 1, taking 50-54 parts of ferric oxide, 20-27.5 parts of manganese oxide, 18-23 parts of zinc oxide and 1-3 parts of calcium oxide in parts by weight, mixing and carrying out oxidation sintering to prepare a Mn-Zn-Fe material; 2, grinding the sintered Mn-Zn-Fe material into granules; 3, taking 65-80 parts of the granular Mn-Zn-Fe material and 20-35 parts of plastic material in parts by weight, mixing, pumping into particles, and then baking the granulated mixture of the Mn-Zn-Fe material and the plastic material at 100-150 DEG C for 2 hours; 4, making the granulated mixture of the Mn-Zn-Fe material and the plastic material into the magnetic stripe in an extrusion and injection molding mode. Compared with the prior art, the method has the advantages of simple production process, capable of greatly improving production efficiency and greatly reducing cost, little in pollution, and energy-saving.

Description

Technical field [0001] The invention relates to a magnetic strip for an induction cooker, in particular to a manufacturing method of the magnetic strip for an induction cooker. Background technique [0002] At present, the magnetic strips of electromagnetic induction heating coils sold on the market are all ferrite, which can be divided into two types: manganese-zinc series and nickel-zinc series. The production process is particularly complicated, and it is only required for sintering in the furnace. For more than 20 hours, sintering requires a furnace temperature of up to 1000°C, which consumes a lot of electricity, and will cause a large amount of powder during production, which will pollute the environment and is listed as a banned polluting enterprise by many local governments. Summary of the invention [0003] The main purpose of the present invention is to provide a method for manufacturing a magnetic strip for an induction cooker with simple production process, high produc...
