Wherein the method comprises the following steps: the method comprises the following steps: smelting, rolling, annealing, surface treatment and drawing.
Wherein the method comprises the following steps: the method comprises the following steps:
smelting: adding an alloy element into pure Fe with the purity of 99.5%, wherein the alloy element is added in the form of Cr-Fe alloy as an alloy element Cr; vacuum degree of less than or equal to 1 × 10-2Smelting in a smelting furnace with the smelting temperature of 1500 and 1550 ℃ under Pa, and casting ingots;

the surface treatment comprises alkaline boiling and pickling;
and the drawing is to draw the electrothermal alloy wire by 18 passes.
Compared with the closest prior art, the technical scheme provided by the invention has the following excellent effects:
according to the technical scheme provided by the invention, the rare earth elements (La, Ce and Er) improve the composition of the Fe-Cr-Al alloy oxide film, and the formed rare earth compound is enriched on the interface layer, so that the diffusion speed of oxygen to the interior of the alloy is slowed down, and the oxidation resistance is improved.
The main function of the chromium element in the technical scheme of the invention is to improve the medium corrosion resistance, because when the content of Cr exceeds 26 percent of the invention, sigma phase is easy to generate to cause alloy embrittlement, so the content of the chromium element is controlled to be Cr: in the range of 23-26%.
The aluminum in the technical scheme provided by the invention is a key element for improving the oxidation resistance of the alloy. The basic reason for the superior oxidation resistance of the iron-chromium-aluminum alloy is the existence of aluminum element, but the aluminum element can cause strong embrittlement of ferrite and sharply reduce the plasticity of the alloy, so the invention controls the aluminum content in the iron-chromium-aluminum alloy within the range of 5-7%.
The Ti in the technical scheme provided by the invention is controlled within the range of 0.02-0.1%, so that the processing performance of the alloy can be improved, and the service performance of the alloy can also be improved.
The technical scheme provided by the invention can also improve the oxidation resistance of the alloy by adding the silicon element with the Si content of less than or equal to 0.3 percent, and the excessive silicon element can cause the plasticity of the alloy to be poor, so the content of the silicon element is generally controlled to be less than or equal to 0.3 percent.
The manganese element in the technical scheme provided by the invention is an element carried by the raw material in the preparation process of the iron-chromium-aluminum alloy, generally plays no role, but the oxidation resistance of the alloy is reduced due to the excessively high content of the manganese element, so that the content of the manganese element is controlled to be less than or equal to 0.4 percent.
The C, P and S elements in the technical scheme provided by the invention are impurity elements in the alloy, and the C + P + S is controlled to be less than or equal to 0.03 percent.
According to the technical scheme provided by the invention, the rare earth element is compositely added into the Fe-Cr-Al alloy, the impurity elements are strictly purified and controlled by utilizing the interaction of micro-alloy elements, and the crystal grains are refined, so that the microstructure of the alloy is improved, and the electric service life of the electrothermal alloy is prolonged. Obtaining cast ingots (the vacuum degree is less than or equal to 1 multiplied by 10) by vacuum smelting-2Pa, the smelting temperature is 1500-.
