In the past, it is known that there is a method of heating the iron metal parts and aluminum metal parts by holding zinc or zinc wire between the iron metal parts and aluminum metal parts and joining the two parts. Then, let's understand the production method of zinc wire together.

Zinc wire can inhibit the gasification of molten zinc solution and melt Si powder. However, even in this case, because the specific gravity of Si is smaller than that of Zn, when Si powder is added to z molten zinc solution, it will cause the problem that Si powder will be suspended near the liquid level of the molten zinc solution, and it will be difficult to mix evenly. Thus, ZN-Si alloy with uniform composition can be obtained.

The zinc wire comprises a process of heating metallic Zn arranged in the crucible of a heating furnace to obtain a molten zinc solution; The process of heating the metal Zn in the crucible in the heating furnace to obtain molten zinc solution, the process of melting the metal Si powder under the condition of covering the molten zinc liquid surface with carboniferous materials, the process of melting the metal Si powder, lifting the floating suppression part of the metal Si powder, so that the molten Si dispersed in the molten zinc solution. Steps for obtaining the molten liquid of the Zn-Si alloy, and the steps for filling the molten liquid of the Zn-Si alloy into the casting mold

The zinc wire melts the metal Zn in a crucible arranged in a heating furnace. This is because at this time the material present in the said crucible is Zn and unavoidable impurities, and can in fact be regarded as Zn only. Therefore, molten zinc (Zn) liquid can be obtained by heating the crucible to a temperature above 420C, the melting point of Zn, in a heating furnace.

Then, add metal Si powder to the molten zinc solution to melt the metal Si powder. Here, the melting point of Si alone is 1414C, which is the temperature above the boiling point of Zn 907C. However, by using Zn-Si alloys, it is possible to bring the melting point of Si to a temperature lower than the boiling point of Zn.
