Magnesium and magnesium alloy half a continuous casting engineering system point:
Melt the surface of the liquid magnesium oxide film is loose, and is lively element, and oxygen binding force strong, smelting, and oxygen in the atmosphere, water vapor, nitrogen response, generating oxide and nitrogen compounds, which becomes a impurities, inclusion place often with porosity and vent. So the melt purification magnesium effect and to strictly control the pouring temperature is half the continuous casting key, good equipment engineering system is smooth running of the premise

The department magnesium and magnesium alloy half a continuous casting system features below:

(1) with mechanical agitation and gas mixing combine to make the crucible of magnesium in liquid produce circumference and upper and lower rolling cycle to flow to make the refining of magnesium in flux and melt of oxide inclusions fully combined adsorption, because produce compounds proportion than magnesium melt, heat preservation quiet place precipitation in the crucible bottom when, a proportion of the lighter oxide impurities floating in magnesium melt surface, so as to achieve the purpose of purifying magnesium melt. Using this device to melt and refining of magnesium agent in effectiveness and efficiency combined ways than the general blender have greatly increased, can generally make refined agent in less to good refined effect;

(2) USES the many kinds of gas shielding mixed smelting technology, the technology to greatly improve the grade of magnesium alloys, the general SF6 + N2 + dry bath air, SF6 + CO2 + dry bath empty or SO2 + N2 + dry air mixing a gas, we have successfully used by the central supply system to each line of the gas supply gas path control control system
(3) according to the customer's specific requirements, and magnesium and magnesium alloy  using relevant melting mode, we have successfully used by a resistance heating melting furnaces + a heat insulation resistance standing for furnace + vertical twin screw half a continuous casting machine in the casting bar system, including melting furnaces of magnesium slag removal by liquid purification, heat preservation stalling, turn by turn, pump liquid pipe (electric heating), transfer to holding furnace, then the rest for heat preservation, the pouring pump, pouring the transfer to the middle pack (former liquid box), then the tundish to a half the continuous casting machine. Turn of pump and the middle box we have applied for the national patent. Also can be customized according to the need of the regenerative heating furnace burning gas + insulation pattern, so as to make energy efficiency by ****0%
