Scrap iron impurities on exercise is very harmful, low silicon powder recycled aluminum, iron too much time would constitute a brittle metal crystals in aluminum, then reduce its mechanical function, and weaken their resistance to corrosion. Iron content should normally be controlled at 1.2% or less. About iron content of 1.5% or more of lead scrap can be used deoxidizer steel industry, commercial aluminum rarely use high iron content of scrap melting. Currently, low silicon powder specifications, the aluminum industry has not been very successful way to satisfactorily remove excess scrap iron, low silicon powder price, especially in the presence of iron stainless way. The main unit is recycled aluminum melting furnace and the essence of purifying furnace, usually use oil or gas furnace dedicated stand. China's largest recycled aluminum company is located on the outskirts of Shanghai Shanghai Sigma Metals Co. Ltd., which has two sets of 50t melting holding furnace, low silicon powder, a group of fuel melting holding furnace 40t; 12t of fuel a rotary kiln . Small companies can choose furnaces, crucibles kiln exercise. p>? head casting combination of both shortened technical process, but also a maximum limit to prevent air pollution, and so that net metal recovery rate is greatly improved. Low silicon powder specifications, NWS metallurgy (online consultation), low silicon powder by the newly created Anyang Metallurgical Materials Limited. New Year Anyang Metallurgical Materials Co., Ltd. (www.ayxyyj.com) (www.ayxcyj.com) is Anyang, powder metallurgy leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum meet customer needs. In the New Year metallurgy leadership with the staff warmly welcome all inquiries negotiations, a total innovation create a better future for metallurgy.
