Its performance and service life directly affect the quality and stability of heating equipment. In the production process, a series of technical requirements need to be met in terms of material selection, processing, process control, etc. The following are the main technical requirements for the production of electric heating wire:<\/p>\n<hr \/>\n<h3><strong>1. Raw material selection<\/strong><\/h3>\n<ul>\n<li><strong>High quality alloy material<\/strong>: Commonly used electric furnace wire materials include iron-chromium-aluminum alloy (Fe-Cr-Al) and nickel-chromium alloy (Ni-Cr).\n<ul>\n<li><strong>Iron-chromium-aluminum alloy<\/strong>: With high resistivity and excellent oxidation resistance, it is suitable for high temperature applications (operating temperature up to 1400\u00b0C).<\/li>\n<li><strong>Nichrome<\/strong>: It has good toughness and corrosion resistance, suitable for low temperature and humid environment.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Purity requirements<\/strong>\uff1aThe impurity content in the raw materials needs to be strictly controlled to avoid problems such as oxidation, embrittlement or breakage at high temperatures.<\/li>\n<li><strong>Uniformity<\/strong>\uff1aThe material composition is evenly distributed to ensure stable resistance value and avoid uneven heating or local burning.<\/li>\n<\/ul>\n<hr \/>\n<h3><strong>2. Production process requirements<\/strong><\/h3>\n<h4><strong>(1) Alloy smelting<\/strong><\/h4>\n<ul>\n<li><strong>High temperature melting<\/strong>: Melting must be completed under vacuum or protective atmosphere to reduce oxidation and impurities.<\/li>\n<li><strong>Ingredients Ratio<\/strong>: Strictly control the content of each element in the alloy, such as chromium, nickel, aluminum, etc., to achieve the resistivity and mechanical properties required by the design.<\/li>\n<\/ul>\n<h4><strong>(2) Wire drawing and rolling<\/strong><\/h4>\n<ul>\n<li><strong>Wire drawing process<\/strong>: To process the alloy billet into wire of required diameter, it is necessary to control the drawing rate and cooling speed to avoid excessive internal stress.<\/li>\n<li><strong>Dimensional accuracy<\/strong>: The diameter error of the electric furnace wire should be within \u00b10.01mm to ensure the stability of the resistance value.<\/li>\n<li><strong>Surface quality<\/strong>: The surface after drawing should be smooth and free of cracks to avoid local defects causing breakage.<\/li>\n<\/ul>\n<h4><strong>(3) Heat treatment (annealing process)<\/strong><\/h4>\n<ul>\n<li><strong>Purpose<\/strong>: Annealing can eliminate residual stress during the drawing process and improve the toughness and oxidation resistance of the material.<\/li>\n<li><strong>Temperature control accuracy<\/strong>: The annealing temperature needs to be precisely controlled, generally in the range of 800\u00b0C to 1100\u00b0C, to avoid overburning or insufficient annealing.<\/li>\n<li><strong>Protective atmosphere<\/strong>: Annealing is performed in an inert gas or vacuum environment to prevent surface oxidation.<\/li>\n<\/ul>\n<h4><strong>(4) Surface treatment<\/strong><\/h4>\n<ul>\n<li><strong>Cleaning and polishing<\/strong>: Remove surface oil, oxides and impurities to ensure a smooth surface.<\/li>\n<li><strong>Coating<\/strong>\uff1aSome special purpose electric furnace wires may need to add anti-oxidation or anti-corrosion coating to extend the service life.<\/li>\n<\/ul>\n<h4><strong>(5) Forming and cutting<\/strong><\/h4>\n<ul>\n<li>According to customer needs, the electric furnace wire is processed into a specific shape (such as spiral) or cut into a specified length. Mechanical damage should be avoided during the forming process.<\/li>\n<\/ul>\n<p><img fetchpriority=\"high\" decoding=\"async\" class=\"alignnone size-full wp-image-30400 aligncenter lazyload\" src=\"data:image\/gif;base64,R0lGODlhAQABAIAAAAAAAP\/\/\/yH5BAEAAAAALAAAAAABAAEAAAIBRAA7\" data-src=\"https:\/\/www.ray-tron.com\/wp-content\/uploads\/2024\/11\/202411201600162.jpg\" alt=\"\" width=\"650\" height=\"457\" \/><noscript><img decoding=\"async\" class=\"alignnone size-full wp-image-30400 aligncenter lazyload\" src=\"https:\/\/www.ray-tron.com\/wp-content\/uploads\/2024\/11\/202411201600162.jpg\" alt=\"\" width=\"650\" height=\"457\" srcset=\"https:\/\/www.ray-tron.com\/wp-content\/uploads\/2024\/11\/202411201600162.jpg 650w, https:\/\/www.ray-tron.com\/wp-content\/uploads\/2024\/11\/202411201600162-300x211.jpg 300w, https:\/\/www.ray-tron.com\/wp-content\/uploads\/2024\/11\/202411201600162-600x422.jpg 600w\" sizes=\"(max-width: 650px) 100vw, 650px\" \/><\/noscript><\/p>\n<hr \/>\n<h3><strong>3. Performance Testing<\/strong><\/h3>\n<h4><strong>(1) Electrical properties<\/strong><\/h4>\n<ul>\n<li><strong>Resistivity<\/strong>\uff1aIt must meet the design standards, and the general measurement error should be within \u00b11%.<\/li>\n<li><strong>Heating uniformity<\/strong>: When heating, the surface temperature distribution should be uniform to avoid local overheating.<\/li>\n<li><strong>Temperature coefficient<\/strong>: Test the resistance change rate at different temperatures to ensure stable performance.<\/li>\n<\/ul>\n<h4><strong>(2) Mechanical properties<\/strong><\/h4>\n<ul>\n<li><strong>tensile strength<\/strong>: The material standard value must be met to prevent breakage during use.<\/li>\n<li><strong>Ductility and toughness<\/strong>: The electric furnace wire should have no cracks when bending or forming to meet processing requirements.<\/li>\n<\/ul>\n<h4><strong>(3) High temperature resistance<\/strong><\/h4>\n<ul>\n<li><strong>Antioxidant<\/strong>\uff1aTest the oxidation rate in a high temperature environment to ensure that oxidation and shedding will not occur during long-term operation.<\/li>\n<li><strong>Corrosion resistance<\/strong>: Test the corrosion resistance of materials in a humid or corrosive gas environment.<\/li>\n<\/ul>\n<h4><strong>(4) Service life<\/strong><\/h4>\n<ul>\n<li>Durability tests are carried out through simulated working conditions to evaluate the life of electric furnace wire under high temperature and long-term operation.<\/li>\n<\/ul>\n<hr \/>\n<h3><strong>4. Packaging and storage requirements<\/strong><\/h3>\n<ul>\n<li><strong>Moisture-proof and anti-corrosion packaging<\/strong>: Use moisture-proof packaging materials to seal and prevent the material from getting damp or oxidized.<\/li>\n<li><strong>Standardized storage<\/strong>: Store in a dry, ventilated warehouse and avoid contact with acidic or alkaline substances.<\/li>\n<\/ul>\n<hr \/>\n<h3><strong>5.
