Induction furnace The elaboration and fusion of high added value materials or the improvement of the materials’ physical properties all take place in vacuum or controlled atmosphere furnaces. The following technologies can be used: n n n n Cold crucible (crucible with cooled copper or stainless steel parts); Hot crucible (graphite or other); Susceptor or muffle radiating (on the heated material); Plasma solutions. TYPES OF APPLICATION Elaboration and fusion of materials titanium, Inconel®, zirconium, uranium, steel, aluminum, copper, cobalt, nickel, glass, enamel, ceramic, silicon, high added-value alloys Improving the materials’ physical properties In addition to the previous materials: graphite, carbon*carbon , aluminum, stainless steel, steel n Complex processes at high temperature (3,000 °C) n Quick temperature increases (from 30 °C/s to 600 °C/s) n Can be used in complex environments like explosive atmospheres, corrosive or nuclear environments (uranium, zirconium, glass…) n Reproducible, robust induction system requiring few consumables n Guarantee of the purity of the material produced in a cold crucible (titanium, Inconel®…) Conventional furnaces typically use graphite, refractory, porcelain or metallic crucibles depending on the requirements of the process being developed. The capacities can range from a few kilograms to a few tons for R&D or industrial uses. COLD CRUCIBLE This technology can be used to attain high temperature requirements (3,000 °C), to melt highly reactive materials at high temperatures (oxides, titanium and others) or to obtain a high level of purity. Capacity from one kg to several hundred kg (e.g. 500 kg of oxides at 3,000 °C) Examples of titanium-based specifications Titane 1,800 °C

POTENTIAL MODULARITY Our furnaces are also designed to be flexible and modular, meaning that they are also designed to facilitate the development of new materials and to allow the integration of various technical improvements resulting from R&D programs. n Laboratory furnace Hot crucible and cold crucible with a multi-sampling system Gravity casting The alternative to traditional tilting casting Under air, neutral gases and vacuum up to 1,200 °C DEVELOPMENT OF PROCESSES ECM Technologies works closely with its partners from the initial R&D stage right up to the delivery of a turnkey...
