When the mould is dried and solidified,aluminum solution of about 700 ℃ is poured into the mould according to the process of ZCAST technique,and the syphon casting is successfully made.

Development of Isothermal Holding Furnace for High Quality Aluminum Alloy Melt;

The on-line testing of hydrogen content in the molten aluminum alloy is very important for producing aluminum alloy castings of high quality.

In order to clear the phenomenon,the Al-Fe alloy liquids used in hot dip aluminizing were quickly solidified and slowly solidified respectively.

Analyzing the reasons producing gas and impurity in Molten aluminium alloy,the auther presented the technical principle of purifying process Discussions on the advantage of spray blowing refine,the technology and equipment of spray blowing refinement in China and abroad were put forwar

The fluoride aluminum complex solution from the bastnaesite oxidation roasting-dilute sulphuric acid leaching-extracting and washing was used as raw material,cryolite was precipitated by making up villaumite and sodium salt in the solution,and controlling F/Al ratio,Na/Al ratio and adjusting the pH value,after filtering,washing and drying to obtain cryolite product.
