The core of the magnesium alloy continuous ingot casting machine is the continuous casting technology. Continuous casting technology is a kind of casting method that continuously injects liquid metal into one end of the through-mould and continuously pulls out the moulding material from the other end. When the casting is pulled out from the metal type after a certain length, the casting can be cut off while pouring; it is also possible to stop pouring when the casting reaches a certain length to obtain a certain length of casting. Magnesium alloy continuous ingot casting machine can be used for casting all kinds of high-density plates, round bars, hollow tubes and other profiles.

The development of magnesium alloy continuous ingot casting machine has changed the status quo of low efficiency and high consumption of metal materials, and has incomparable technical advantages. Generally speaking, magnesium alloy continuous ingot casting machine has the following technical characteristics:
1, due to the rapid cooling of the metal, its crystallisation is fine, dense organisation, good mechanical properties; continuous casting, the crystallisation process will make the casting’s organisation uniform throughout its length;.
2、Because there is no gate, can save the amount of metal, improve the rate of finished products;.
3、Simplify the process, eliminating the need for styling and other processes, reducing labour intensity; the required production area is also greatly reduced;.
4, continuous casting production is easy to achieve mechanisation, automation, improve production efficiency.
5, if the continuous casting of high-temperature ingots obtained immediately rolled, you can save the ingot in the general rolling before the heating process, can greatly save energy and improve efficiency.
Magnesium alloy continuous ingot casting machine feeding pot and related hot parts and Germany imported steel, using optimised process manufacturing, has good high temperature performance, corrosion resistance, wear resistance, long service life. Magnesium alloy hot chamber die casting machine solidification holding furnace is well-designed and manufactured, the hot parts are made of imported steel, corrosion-resistant and high-temperature-resistant, this series of furnaces can be used with all kinds of hot chamber moulds – casting machine, low energy consumption, high condensation rate, gas protection device is perfect, and the gas is mixed evenly.
Low energy consumption, high condensation rate perfect gas protection device, gas mixing uniformity, stable flow, full protection, equipped with automatic switching device bimetallic composite steel plate manufacturing crucible, no pollution of magnesium liquid, long service life of the heating element work stably, with a long service life of a number of thermocouples to control the temperature of the furnace chamber and the box body automatic alarm device: over-temperature alarm, liquid leakage alarm.
In 1200-1250 ℃, 1.33Pa vacuum conditions recycling production of crude magnesium, through the melt refining, ingot casting, surface treatment to get the finished magnesium ingot. Pijiang magnesium smelting defects: consumption of 1 ton of magnesium metal ingots need to consume 12-14 tonnes of dolomite; 8-10 tonnes of anthracite and bituminous coal; 5-6 tonnes of by-products of recycling slag, these recycling slag in the past did not find a better use, pollution of the environment; labour intensity, raw material workshop dust pollution is serious, nickel content is too low, the recovery of the use of flotation, but impurity magnesium may not be easy to control.
