Optimum addition of Eccomelt to an A356 charge that will provide an economic gain without compromising the metallurgical quality of the casting produced

Eccomelt是House of Metals的子公司，通过获得专利的清洁和破碎工艺，生产和销售一种通过回收铝圈生产和销售的铝合金。这种产品被称为Eccomelt356.2，其成分与A356.2钢锭非常相似，并作为原铝A356.2的替代品提供给铸造厂。为了增加其在关键汽车市场的市场份额，金属之家希望发展铸造实践，包括在不影响全部或部分由Eccomelt356.2制成的铸造产品的机械性能的情况下，用A356.2原锭稀释。本项目的目标是研究液态金属处理对T6和T61回火铸件冶金质量的影响，这些铸件包括砂型、金属型和通常采用特殊热处理的高压压铸件。采用最佳的熔融金属处理工艺，以不同的初生锭与Eccomelt356.2的混合比例制备Eccomelt炉料。金属质量将通过从这些熔体浇注的样品进行拉伸测试、PODFA夹杂物含量和金相评估来评估。该研究项目将使工业合作伙伴更好地了解铸造条件对ECcomelt356.2铸件性能的影响。有了这个项目中获得的数据，金属之家将能够指导其客户(铸造厂)优化其产品的使用，以获得尽可能好的铸件性能。这将使Eccomelt365.2合金在作为可回收产品的初始经济和环境优势之外，获得额外的竞争优势。Cégep de Trois Rivières的一名学生将在项目的每一年参与该项目。

Eccomelt, a subsidiary of House of Metals, produces and markets an aluminum alloy from the recycling of aluminum rims through a patented process of cleaning and fragmentation. This product, known as Eccomelt356.2, has a composition very similar to that of A356.2 ingots and is offered to foundries as a substitute for primary aluminum A356.2. To increase its market share in the critical automotive market, House of Metals wants to develop foundry practices including dilution with A356.2 virgin ingots without affecting the mechanical properties of cast products made in whole or in part from Eccomelt356.2. The project goal is to study the effect of the molten metal treatment on metallurgical quality of casting in the T6 and T61 tempers of sand, permanent mold and high pressure die casting usually with special adapted heat treatments. Charges of Eccomelt will also be prepared with different mixing ratio of virgin ingots to Eccomelt356.2 treated with the best molten metal treatment processes. Metal quality will be assessed by tensile test from sample poured from those melt, by PoDFA for inclusion contents and metallographic evaluation.This research project will enable the industrial partner to gain a better understanding of the effect of casting conditions on the properties of parts cast from Eccomelt356.2. With the data obtained in this project, House of Metals will be able to guide its customers (foundries) towards an optimal use of its product in order to obtain the best possible properties of the castings. This should give the Eccomelt365.2 alloy an additional competitive advantage in addition to its initial economic and environmental advantage as a recycled product. One student from the Cégep de Trois Rivières will participate in the project for each year of the project.
