This show in detail.<\/p>\n<p><strong>Electric Arc Furnace (EF)<\/strong><\/p>\n<p>The electric arc furnace process is popularly steel making process in America. Many manufacture use this process around 20% in 1975 and increase to 50% in 2000 because of this process consume the energy less than other process. The electric arc furnace process start with input the scraps into the furnace after that the electrode rod that applied the electric current are moved to close the scrap. The high voltage electrode pole and scraps are more than 500 volt and occur electric arc that increase the temperature of scraps more than 2000\u02daC . This temperature will change solid scraps to liquid metal. While scrap have been melted ,the arc process will reduced gradually and then oxygen have been filled into the liquid metal for oxidation reaction. After oxidation reaction the impurities in liquid metal will be oxide form and form to slag. In this method will remove contaminated alloy and purify liquid metal. After that the liquid metal will transfer next process for add alloy as standard\u2019s requirement. All of this process are make batch to batch that not continuous production but the advantage of this process is better control the quality of each batch more than continuous process.<\/p>\n ","protected":false},"excerpt":{"rendered":"<p>Requirements of standard According to the requirements of TIS24-2548(2005) Thailand [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":595,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"inline_featured_image":false,"_monsterinsights_skip_tracking":false,"footnotes":""},"categories":[25],"tags":[],"class_list":["post-594","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-article-and-knowledge"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v26.2 - https:\/\/yoast.com\/wordpress\/plugins\/seo\/ -->\r\n<title>Production Process - Electric Arc Furnace (EF) - TATA STEEL (Thailand) PLC.<\/title>\r\n<meta name=\"robots\" content=\"index, follow, max-snippet:-1, max-image-preview:large, max-video-preview:-1\" \/>\r\n<link rel=\"canonical\" href=\"https:\/\/tatasteelthailand.com\/production-process-electric-arc-furnace-ef\/\" \/>\r\n<meta property=\"og:locale\" content=\"en_US\" \/>\r\n<meta property=\"og:type\" content=\"article\" \/>\r\n<meta property=\"og:title\" content=\"Production Process - Electric Arc Furnace (EF) - TATA STEEL (Thailand) PLC.\" \/>\r\n<meta property=\"og:description\" content=\"Requirements of standard According to the requirements of TIS24-2548(2005) Thailand [&hellip;]\" \/>\r\n<meta property=\"og:url\" content=\"https:\/\/tatasteelthailand.com\/production-process-electric-arc-furnace-ef\/\" \/>\r\n<meta property=\"og:site_name\" content=\"TATA STEEL (Thailand) PLC.\" \/>\r\n<meta property=\"article:published_time\" content=\"2020-03-26T17:55:55+00:00\" \/>\r\n<meta property=\"article:modified_time\" content=\"2020-07-11T12:54:21+00:00\" \/>\r\n<meta property=\"og:image\" content=\"https:\/\/tatasteelthailand.com\/wp-content\/uploads\/2020\/07\/5c9c92d27383c-1.jpg\" \/>\r\n\t<meta property=\"og:image:width\" content=\"600\" \/>\r\n\t<meta property=\"og:image:height\" content=\"400\" \/>\r\n\t<meta property=\"og:image:type\" content=\"image\/jpeg\" \/>\r\n<meta name=\"author\" content=\"unknown\" \/>\r\n<meta name=\"twitter:card\" content=\"summary_large_image\" \/>\r\n<meta name=\"twitter:label1\" content=\"Written by\" \/>\n\t<meta name=\"twitter:data1\" content=\"unknown\" \/>\n\t<meta name=\"twitter:label2\" content=\"Est. reading time\" \/>\n\t<meta name=\"twitter:data2\" content=\"1 minute\" \/>\r\n<script type=\"application\/ld+json\" class=\"yoast-schema-graph\">{\"@context\":\"https:\/\/schema.org\",\"@graph\":[{\"@type\":\"Article\",\"@id\":\"https:\/\/tatasteelthailand.com\/production-process-electric-arc-furnace-ef\/#article\",\"isPartOf\":{\"@id\":\"https:\/\/tatasteelthailand.com\/production-process-electric-arc-furnace-ef\/\"},\"author\":{\"name\":\"unknown\",\"@id\":\"https:\/\/tatasteelthailand.com\/#\/schema\/person\/550063028fc5e9a8208eed0238690334\"},\"headline\":\"Production Process &#8211;
