CO.RAM, a strategic partner of CD Automation for several years, has extensive expertise in addressing challenges related to light alloy metallurgy, a relatively new field that undergoes continuous and exciting innovations.<\/p>\n<p><iframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/moR8QCsFLwA?rel=0&amp;controls=1&amp;showinfo=0&amp;loop=1&amp;playlist=moR8QCsFLwA\" width=\"640\" height=\"410\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/p>\n<h2>A delicate transition<\/h2>\n<p>The biggest change in furnaces for the metallurgical treatment of light alloys is the <strong>transition from gas heating systems to electric systems<\/strong>. This is a change that is as necessary as it is challenging, requiring not only new skills but also<strong> timely and continuous support between companies<\/strong>. Hence the need to forge strategic partnerships, in a two-way exchange of know-how that enhances the authority of the entire sector.<\/p>\n<h2>Resistive elements and silicon carbide: limitations and solutions<\/h2>\n<p>Delving into the specific application, CO.RAM turned to CD Automation for the <strong>correct management of the resistive elements<\/strong> used in electric heating systems. The main objective of the partnership was linked to the need to deliver the maximum possible power to the system without compromising the operation and integrity of these resistors.<\/p>\n<p>To date, <strong>silicon carbide<\/strong> is the most efficient resistive element. It has the highest specific power rating on the market; however, its crystalline structure imposes significant limitations in terms of <strong>fragility<\/strong> and power degradation.<\/p>\n<p>To compensate for this fragility, CO.RAM has adopted the <strong>latest generation of CD Automation power units<\/strong>, which include a <strong>soft-start function<\/strong>. This function allows the output power to be limited over a certain period of time or to ramp up to the set point when the control is activated, in order to avoid thermal shock to the heating elements.<\/p>\n<p>The problem of power decay for resistors in electric heating furnaces has been solved by using a leading product from CD Automation: <a href=\"https:\/\/www.youtube.com\/watch?v=uZ5nOxkK3js\" target=\"_blank\" rel=\"noopener\"><b>REVO C<\/b><\/a>. This unit can be connected to configuration software capable of analysing all the electrical data of the process and configuring the parameters necessary for the optimal use of silicon carbide heating elements, compensating for voltage in a linear manner in order to maintain power at a near-constant level.<br \/>\nThe advantage offered by the REVO C unit is therefore crucial, as <strong>it extends the lifespan of the silicon carbide elements<\/strong>.<\/p>\n<p><img fetchpriority=\"high\" decoding=\"async\" src=\"https:\/\/www.cdautomation.com\/blog\/wp-content\/uploads\/SiC-and-REVO-C.webp\" alt=\"REVO C Thyristor unit to drive SiC heating elements\" width=\"672\" height=\"377\" class=\"alignnone size-full wp-image-4553\" srcset=\"https:\/\/www.cdautomation.com\/blog\/wp-content\/uploads\/SiC-and-REVO-C.webp 672w, https:\/\/www.cdautomation.com\/blog\/wp-content\/uploads\/SiC-and-REVO-C-300x168.webp 300w, https:\/\/www.cdautomation.com\/blog\/wp-content\/uploads\/SiC-and-REVO-C-150x84.webp 150w\" sizes=\"(max-width: 672px) 100vw, 672px\" \/><\/p>\n<h2>Consumption monitoring<\/h2>\n<p>The REVO C power regulator meets another primary need for companies operating in the metallurgical treatment and smelting furnace sector: energy calculation. Through configuration software, data loggers and the most widely used field buses, the unit <strong>allows strategic data to be acquired on process variables<\/strong> such as voltage, resistance, current, power and absorption, in order to verify the efficiency and correct functioning of electric heating processes.<\/p>\n<h2>Control at your fingertips with your smartphone<\/h2>\n<p>The service offered by CD Automation also meets some of the objectives of <strong>Industry 4.0<\/strong>, a paradigm that encourages the use of <strong>remote assistance<\/strong> to reduce production costs, minimise maintenance downtime, optimise on-site solutions and streamline processes.<\/p>\n<p>In line with this objective, CD Automation has developed a <strong><a href=\"https:\/\/www.cdautomation.com\/products\/revo-c-family\/#app\" target=\"_blank\" rel=\"noopener\">new app<\/a><\/strong>, available for iOS and Android, which facilitates the connection of REVO C units with smartphones. The app can detect the various units within Bluetooth communication range, reporting operating and electrical parameters, as well as an analysis of energy consumption during the process. It also allows users to enable, disable, and configure features, as well as control the operation of the various units.<\/p>\n<p>Thanks to this app, the CD Automation team can provide top-level support to operators who interface with power units, displaying parameters in real time and suggesting the most appropriate solutions.<\/p>\n<p>To learn more about these topics and the comparison between CD Automation and Co.RAM on electric heating, watch the <a href=\"https:\/\/www.youtube.com\/watch?v=aWZcje8eZvg\" target=\"_blank\" rel=\"noopener\"><strong>full interview<\/strong><\/a> video with english subtitles.<\/p>\n<p><iframe title=\"YouTube video player\" src=\"https:\/\/www.youtube.com\/embed\/aWZcje8eZvg?rel=0&amp;controls=1&amp;showinfo=0&amp;loop=1&amp;playlist=aWZcje8eZvg\" width=\"640\" height=\"410\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/p>\n<p style=\"text-align: center;\"><strong>Would you like to learn more about how REVO C can make the thermoregulation processes of your electrically heated melting furnaces more efficient and sustainabl? <a href=\"https:\/\/www.cdautomation.com\/contact-us\/\">Contatact us<\/a> and book a free consultation session with one of our experts.<\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>The rapid spread and growing market interest in electric heating have inspired the creation of a series of interviews, available on our YouTube channel, dedicated to exploring the topics of greatest interest in the sector.
