The shell of magnesium alloy furnace is made of high quality steel plate and high quality insulation material. The furnace has advanced structure, low energy consumption and fast melting speed. The design of double chamber crucible is reasonable and can be used in two die casting machines at the same time. High quality imported radiation processing thermal components, long service life, high thermal efficiency.

I. What are the advantages of magnesium alloy smelters?

1. Enhanced furnace body and insulation layer design, excellent high temperature performance, furnace wall temperature is lower than the national industrial furnace standards.

2. Bimetallic composite steel plate manufacturing crucible, does not pollute the magnesium liquid, long service life.

3. Siemens programmable control system and Siemens temperature module can ensure the precise control of the furnace system.

4. The gas flowmeter imported from USA can accurately control the protective gas.

5. Pot and related hot work parts and imported steel from German enterprises can be used to optimize the production process design and manufacturing, high temperature performance, corrosion resistance, wear resistance, long service life. Magnesium alloy hot chamber die casting machine melting preservation bright simple Qian De Zhi long strong temperature furnace, perfect design, excellent manufacturing, hot parts are made of imported steel, corrosion resistance, high temperature resistance, this series of furnaces can be used with all types of hot chamber die casting machine.

Second, what is the method of ladling magnesium alloy furnace?

1. Preheat ladle of ladle tool for 10 minutes and clean ladle surface.

2. Take the magnesium ingot mold out of the oven preheated at about 150℃ and place it on the ground. Keep the N2 flowmeter value at 100 before ladling and feeding. Adjust the SF6 flowmeter value to 20-30. Keep the mixed flow value at 80. Keep ventilation for 5 minutes at this flow rate.

3. Put on protective clothing, mask and heat protective gloves, lift the furnace cover, tilt the feeding spoon 30 degrees, slowly into the feeding liquid, 3/4 of the feeding spoon capacity, slowly raise the liquid level, gently pour the feeding liquid into the magnesium ingot mold, and cover the magnesium ingot mold.

4. After opening the cover, the longest opening time is 3 minutes, otherwise it may cause material fire, must be timely not closed the furnace cover.

5. After taking the material, close the furnace cover. If you want to take the material again, wait for 10 ~ 15 minutes.

6. When taking out materials, the liquid materials and burning materials on the ground should be extinguished with dry sand in time, and the ground should be cleaned up.

7. Fifteen minutes later, the ratio of each table is normal, and the flow rate of N2 is 100. The flow rate of SF6 is 7-8. The value of mixed air flow is 70-80.

Note: There should be no waste slag on the sealing surface of the furnace cover. It should be removed if it falls off accidentally when cleaning the slag. Otherwise, it will cause bad sealing of the furnace and accelerate the oxygenation of liquid material.

Iii. What is the safe operation of magnesium alloy furnace?

1. Personnel shall not enter the equipment area without training.

2. Lighting an open flame or smoking where there is magnesium dust, magnesium powder or magnesium dust may cause explosion.

3. Personal injury or death may occur if the equipment parts are live and the electrical equipment is improperly maintained or the grounding cable is not firm.

4. Random modification of equipment may reduce the safety of equipment and may result in injury or death.

5. Dangerous or incorrect operation of the equipment may result in injury or death.

6. Adding wet or dirty magnesium ingot, magnesium dust, magnesium powder and magnesium slag into the furnace may cause explosion risk. Therefore, the magnesium alloy added to the crucible should be dry, oil-free, dirty, preheating not less than 150℃.

7. The molten magnesium can overflow in the crucible and cause death, so wear protective clothing when melting or eating the magnesium alloy.

Magnesium alloy continuous ingot casting machine manufacturers said that, at present, lead ingot casting equipment has been widely used in domestic lead smelters, the main operation has achieved varying degrees of mechanization or automation, casting, the use of lead pump molten lead pot liquid lead pump into the casting bag, liquid lead through the casting bag quantitative pouring device injected into the ingot mold for casting, scraper liquid lead ingot surface slag layer, Then, after cooling forming, printing and demudding process, the demudding lead ingot is stacked by cantilever hanging. It plays an active role in improving the working conditions and reducing the labor intensity of finished lead ingot.

The core of magnesium alloy continuous ingot casting machine is continuous casting technology

The core of magnesium alloy continuous ingot casting machine is continuous casting technology. Continuous casting is a casting method in which liquid metal is continuously injected into one end of the die and molding materials are continuously pulled out from the other end. When the casting is drawn from the metal form to 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 in order to obtain a certain length of casting. Magnesium alloy continuous ingot casting machine can be used for casting various high density plate, round bar, hollow pipe and other profiles.

Structure introduction of magnesium alloy furnace, come to collect!

Magnesium alloy smelters say that magnesium alloys are very active among all metals because they have an ignition point of 550℃ and a melting point of 650℃. At high temperatures, it reacts with oxygen to form magnesium oxide, while it reacts with water to form hydrogen and magnesium oxide, which causes an explosion. Therefore, metal oxidation or combustion must be prevented effectively in the process of melting magnesium alloy, which is usually achieved in the process of flux or no flux on the surface of metal melt. A large number of experimental studies show that gases such as C02.S02.SF6 can play a good protective role on magnesium and its alloy melt, but these substances will react with magnesium to form other substances. Such substances constitute impurities in magnesium soup, and a large number of impurities will float on the surface of the molten soup or adhere to the furnace side wall, and the dense ones will sink to the bottom of the furnace. When the substance becomes thicker and more concentrated, a large amount of this substance adheres to the crucible wall of the furnace. After a period of time, it will form a hard solid layer of material, causing a decrease in the volume of crucible. At the same time, heat from the external heating device of crucible cannot be properly transmitted into crucible, which reduces the melting speed and cannot meet the production requirements, thus reducing the production efficiency of die casting and seriously affecting the service life and product quality of crucible.

What are the advantages of magnesium alloy smelters? Let's find out.

Function and application of magnesium alloy furnace

In magnesium alloy smelting process, metal oxidation reaction should be avoided to prevent metal combustion. To achieve this effect, we usually sprinkle some flux on the metal melt. Sometimes, we can also use fluxless processes. The common flux is beryllium metal, and the common flux free process is flux free melting. The melting process of magnesium alloy is mainly flux melting. The flux removes impurities from the magnesium and forms a protective film on the surface of the magnesium alloy melt to isolate air. However, the effect of flux film on air isolation is not very ideal, and the magnesium loss caused by oxidation combustion in smelting process is relatively large.
