據(jù)悉，該項(xiàng)發(fā)明通過(guò)控制引燃過(guò)程的工藝，能夠保證完全引燃反應(yīng)，防止內(nèi)部有未反應(yīng)生料；通過(guò)控制補(bǔ)熱過(guò)程的工藝，可延長(zhǎng)高溫還原反應(yīng)時(shí)間，保證還原反應(yīng)完全；通過(guò)控制排氣過(guò)程的工藝，電流分階段梯度降低的送電制度，通過(guò)電流及電壓的作用，使合金內(nèi)的氣體慢慢由合金內(nèi)排出，防止內(nèi)部氧化及氣孔產(chǎn)生。
通過(guò)此項(xiàng)技術(shù)能夠通過(guò)不同電壓、電流的作用，控制電鋁熱法冶煉釩鋁合金的反應(yīng)過(guò)程，使合金中產(chǎn)生的氣體能夠及時(shí)排出合金，有效避免了冶煉過(guò)程中產(chǎn)生的產(chǎn)品氧化及夾渣問(wèn)題，提高了釩鋁合金的產(chǎn)品質(zhì)量。
