Al-Si-Mn alloy and its preparing process

Abstract

An AlSiMn-alloy contains A (19-21 wt.%), Si (16-20 wt.%), Mn (48-52 wt.%), C (0-1.8 wt.%), P (0-0.25 wt.%), S (0-0.04 wt.%) and Fe (rest), and is prepared through thermal resmelting, slogging to remove carbon, adding Al and Si, fastly casting ingots, demoulding, cooling in air. Its advantages are short smelting time and less consumption of Al.

AI Technical Summary

Benefits of technology

This patented new type material with low density makes possible for better utilization of useful materials like iron or manganese during production processes without causing environmental concerns due to its high weight percentage compared to traditional methods used today (aluminium). Additionally, this new method allows for efficient removal of harmful substances from the liquid metal while maintaining good quality properties. Overall, these technical improvements make the product more effective than previously available options.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the performance of traditional methods used during manufacturing process steps such as melting and casting of molten metal (M) ingots made from Mn-, Al-, Si-, Fe--Si alloys containing impurities like iron). These existing techniques have limitations that make it difficult to produce an effective combination of two different types of oxides: monosilane and phosphorus dioxygen gas.
