The flame retardancy of the alloy increases with the addition of Ca and Y
The Mg-3.5Y-0.8Ca flame-retardant magnesium alloy with excellent flame-retardant effect was obtained by the addition of Y and Ca at the same time, and the unprotected melting of magnesium alloy under atmospheric conditions was realized. The surface analysis results of XRD, SEM and AES showed that when Mg-3.5Y-0.8Ca flame-retardant magnesium alloy was exposed to the atmosphere at high temperature, a layer of oxide film dominated by Y2O3 would be formed on the alloy surface. The Y2O3 film has dense structure, strong spreading ability, solid and non-volatile at high temperature, and low conductivity, These properties determine that it is an excellent protective oxide film, which can prevent the further oxidation of magnesium alloy matrix

Compared with cast magnesium alloys, semi-continuous casting casting magnesium alloys are finer in structure, more uniform in composition, denser in interior, and have higher strength and higher elongation than cast magnesium alloys.
1 Through pipetting, secondary scouring, high purity and low impurity, the magnesium liquid is poured directly from the heating and holding furnace to rapidly crystallize, which improves the denseness of the internal metallographic structure of the magnesium rod, and the internal crystal is more reasonable and compact. Physical properties It is also greatly enhanced over traditional cast products.
2 The slag content of flux in molded products tends to be zero, that is, the semi-continuous alloy adopts the new inert gas protection device in the current magnesium smelting industry, which changes the smelting process in the traditional process to be completely exposed to the air, and can only rely on flux and other flame retardants. The material is the most flame-retardant method in magnesium molding products, which greatly reduces the flux slag content and improves product quality.
3 The surface is smooth and clean, no air hole, shrinkage hole, slag inclusion.
4 Flexible length and length, existing specifications Φ 93, Φ 112, Φ 170, Φ 212, Φ 217, Φ 230, can be stripped and cut according to user requirements. In addition, other products with different specifications can also be produced to meet customer requirements. .
5 It is also possible to semi-continuously cast a variety of magnesium alloy flat bars (eg: 200mm x 500mm thick)
