摘要： A metal melting apparatus has a heating furnace, a melting furnace mounted on the heating furnace, a high-cycle regenerative system (FIRS), a raw material feeding device and a melted material feeding device mounted on the melting furnace. The HRS heats and recycles high temperature air in the heating furnace and guides the high temperature air to the preheating screw to preheat metal materials in the preheating screw. Thus, a time for melting the metal materials from solid to liquid is greatly shortened. Furthermore, a series of processes for preheating the metal materials in the raw material feeding device, melting the metal materials in the melting furnace and injecting the molten materials to the molds is fluent, time-saving and safe, and can progress continuously.

摘要： This invention provides a method for overcoming the adverse effects of disintegration of molten steel streams due to sub-surface growth of carbon monoxide bubbles when exposed to reduced pressures and thus permits refining of liquid scrap much the same way as if it were a quiescent liquid melt. Steel scrap contaminated with copper, tin, zinc and organics, such as PVC coating, is preheated and melted continuously using melt circulation and then continuously refined in-line to yield high quality liquid steel and separate non-ferrous metal byproducts by straightforward physical desorption under reduced pressure using an inert strip gas within a desorber and then subsequent iron vapour condensation by direct contacting with liquid steel followed by selective condensation of copper initially and then recovery of tin. Formation of dioxins from scrap containing chlorine is precluded by inline scrubbing of pyrolysis gas formed during scrap preheating. The initial melting of preheated scrap employs melt circulation and gas combustion rather than fossil fuel generated electricity and is thus inherently energy efficient.
摘要翻译：本发明提供了一种克服当暴露于减压时由于一氧化碳气泡的亚表面生长而导致的钢水流分解的不利影响的方法，并且因此允许液体废料的精炼与其静态液体熔体相同。用铜，锡，锌和有机物（如PVC涂层）污染的废钢被熔融循环连续预热和熔融，然后在线连续精炼，得到高品质的液态钢，并通过直接的物理解吸分离有色金属副产物在解吸器内使用惰性带状气体减压，然后通过与液态钢直接接触随后的铁蒸汽冷凝，然后首先选择性地冷凝铜，然后回收锡。通过在废料预热期间形成的热解气体的在线洗涤排除了含有氯的废料形成二恶英。预热废料的初始熔化使用熔体循环和气体燃烧而不是化石燃料发电，因此本来就是能量效率。
