Description
技术领域technical field

目前生产钒钛合金的方法主要是铝热法，铝热法的特点是生产成本低、生产工艺简单，主要工艺流程为冶炼炉准备-配料-冶炼-成批处理，由于工艺较为简单，通过该工艺制得的钒铝合金成品存在以下方面的缺点：一是在冶炼过程中，因为混料不均等原因会造成部分料渣和合金分离不彻底，从而使形成的合金表面夹渣；二是在冶炼完成后，制得的钒铝合金锭在后续的工序中由于受到外力震荡，使钒铝合金锭断裂，会在钒铝合金锭的断裂面形成氧化膜。不论是夹渣还是氧化膜一般都存在于合金锭的断裂缝隙或者表面凹陷处，处理起来非常麻烦，费时费力，且不易处理干净，严重影响成品质量，会产生大量废品。At present, the method of producing vanadium-titanium alloy is mainly the aluminothermic method. The aluminothermic method is characterized by low production cost and simple production process. The main process flow is smelting furnace preparation-batching-smelting-batch processing. The vanadium-aluminum alloy finished product produced by the process has the following disadvantages: first, in the smelting process, due to the uneven mixing of materials, some of the slag and the alloy will not be separated completely, so that the surface of the formed alloy will contain slag; After the smelting is completed, the obtained vanadium-aluminum alloy ingot is subjected to external shocks in the subsequent process, causing the vanadium-aluminum alloy ingot to break, and an oxide film will be formed on the fractured surface of the vanadium-aluminum alloy ingot. Both slag inclusions and oxide films generally exist in the fracture cracks or surface depressions of alloy ingots. It is very troublesome to deal with, time-consuming and laborious, and it is not easy to clean, which seriously affects the quality of finished products and produces a lot of waste products.

c、将喷砂处理后的钒铝合金锭进行破碎，使钒铝合金锭在冶炼炉中形成的氧化膜暴露出来，由于钒铝合金锭在冶炼炉中冶炼完成后会受到外力震荡，大块的钒铝合金锭断裂后会在断裂面或者断裂缝隙中形成氧化膜，此步骤对钒铝合金锭进行破碎，则钒铝合金锭会顺着之前的裂缝断开，使裂缝中的氧化膜暴露出来，便于后续步骤进行清理；c. Break the vanadium-aluminum alloy ingot after blasting to expose the oxide film formed in the smelting furnace. Since the vanadium-aluminum alloy ingot will be subjected to external shocks after smelting in the smelting furnace, large pieces After the vanadium-aluminum alloy ingot is broken, an oxide film will be formed on the fracture surface or in the crack. Come out for easy cleaning in subsequent steps;
d、人工将破碎后的钒铝合金锭中含有氧化膜的合金块和不含氧化膜的合金块分离开来，将完全不含氧化膜的合金块破碎到符合要求的粒度后进行包装；d. Manually separate the alloy block containing oxide film from the alloy block without oxide film in the crushed vanadium-aluminum alloy ingot, and pack the alloy block completely without oxide film to a particle size that meets the requirements;
e、用喷砂机对含有氧化膜的合金块进行二次喷砂处理，完全去除断裂面上的氧化膜；e. Use a sandblasting machine to perform secondary sandblasting on the alloy block containing the oxide film to completely remove the oxide film on the fracture surface;
f、将处理干净的合金块破碎到符合要求的粒度后进行包装。f. Pack the cleaned alloy blocks after crushing to the required particle size.
步骤b和步骤e中，喷砂机所使用的喷砂介质为无杂质白刚玉或高纯铝粉，进行喷砂清理时，不会将杂质带入钒铝合金锭中，可保证成品的纯度。In step b and step e, the sandblasting medium used by the sandblasting machine is impurity-free white corundum or high-purity aluminum powder. During sandblasting, no impurities will be brought into the vanadium-aluminum alloy ingot, which can ensure the purity of the finished product .
