Due to the properties of magnesium itself, it is easy to burn, so it is easy to have fire accidents in the production and processing of magnesium, and its danger is still worth paying attention to. Then we can try to prevent the occurrence of fires from four aspects. 
Magnesium alloy processing parts First, prevent the combustion and explosion of magnesium dust and magnesium dust during magnesium alloy processing Magnesium alloy processing process will produce some dust, can control the processing speed, ensure relatively low humidity, increase the feed rate and eating force, can not be in the processing process pause time is too long, the back corner of the tool and chip space should not be too small, to use the knife cutting liquid, to avoid metal collision sparks, avoid the accumulation of chips and other aspects of control to ensure the safety of the magnesium alloy processing process. Second, magnesium alloy processing operator operation specifications: There should be no flammable and explosive materials at the production site, sufficient fire extinguishing facilities and equipment in the operation area and management area, high space in the production site, good natural ventilation, and strict smoking ban. Operators should conduct safety training and standardize the use of equipment before they can go to work, standardize the use of labor protection supplies and pay attention to safety precautions. Magnesium alloy processing case Third, the magnesium alloy processing and production process is correct fire extinguishing: Let's say something goes wrong at the manufacturing plant and you need to put out the fire. Water is definitely not an option because – as we know – it can make things worse. You can choose from the following fire extinguishers: Dry Class D fire extinguishers are more effective at extinguishing magnesium fires. G-1 blunt graphite-based powder or Met-L-X sodium chloride-based powder cartridge pressurized fire extinguisher, if necessary, can also use storage tanks and barrels to bulk G-1 blunt graphite-based powder to prevent fire development in a serious direction. Fourth, the processing of some magnesium alloys: All heating processes of magnesium alloys should be electrically heated, and a hot air circulation furnace should be used, and the furnace itself must be cleaned regularly to avoid debris or contamination, and the furnace and billet should be completely dried. Shielding gas generally has a dual role: first, it can prevent surface oxidation; Second, in case the furnace temperature is too high, it can effectively prevent the common burning phenomenon. The three shielding gases commonly used are SF6, SO2, and CO2, and other inert gases can also be used. However, due to the high cost of inert gases, they are not suitable in most cases. In the fine grinding and polishing process, because the fine chips and fine powder produced have a large "surface: volume" ratio, so it is easy to reach the ignition temperature, so it is necessary to use inert cutting oil for process lubrication (foreign magnesium alloy strip processing and production is widely used), which can effectively avoid process fire. The above briefly talks about the key points of safe operation in the die-casting and machining process of magnesium alloy, so as to facilitate safe production, protect personal safety and property safety.
