At present, graphite mould has been widely used in the following aspects:
Graphite mould for continuous casting and semi-continuous casting of non-ferrous metals
Artificial graphite is considered to be the most suitable material for continuous or semi-continuous casting of non-ferrous metals. Production practice has proved that the adoption of graphite mould, because of its good performance of thermal conductivity, thermal conductivity performance determines the speed of solidification of the metal or alloy), mold good self-lubricating performance factors, not only make the casting speed, and due to the size of the ingot casting precision, smooth surface, uniform crystal structure, can be directly for the next working procedure of processing. This not only greatly improves the rate of finished products, reduces the loss of waste, but also greatly improves the quality of products. Continuous casting methods are vertical continuous casting method and horizontal continuous casting method.
Die for pressure casting
Artificial graphite materials have been successfully used in pressure casting of non-ferrous metals. For example, zinc alloy and copper alloy castings produced in pressure casting molds made from artificial graphite materials are already used in automobile parts, among other things.
Graphite mould for centrifugal casting
Graphite molds have been successfully used in centrifugal casting. In order to prevent burning loss of artificial graphite mould, certain anti-oxidation measures can be taken. After casting a certain number of castings, if the inner surface of the mold is found to be burned, the size of the inner hole of the mold can be enlarged for casting large size casing.
Hot pressing die
Artificial graphite hot pressing die for cemented carbide pressure sintering has the following characteristics: one is if the pressing temperature is increased to 1350-1450 degrees, the unit pressure required can be reduced to 67-100 kg force/square centimeter (that is, 1/10 of the cold pressing pressure); Second, pressure and heating in the same process, after a short time of sintering can get dense sintering body.
Moulds for glass forming
Due to graphite material with chemical stability, susceptible to infiltration of molten glass, will not change the composition of the glass, graphite material thermal shock performance is good, and small size changes with the temperature characteristics, so in recent years become indispensable in the glass manufacturing mold material, it can be used to manufacture glass tube, pipe, funnel and other forms of special shape of glass bottle mould.
Sintering die and other diamond sintering die
The sintered die and bracket of the transistor can be made by using the characteristics of the artificial graphite material with very little thermal deformation. In addition, graphite molds are also used for casting of cast iron, durable casting of various non-ferrous metals, casting of steel, casting of heat-resistant metals (titanium, zirconium, molybdenum, etc.) and thermite welding of steel rails. The graphite mould used for hot pressing and sintering diamond tools plays a dual role of heating element and mould support in the manufacturing process of diamond tools. The quality of graphite mould directly affects the dimension accuracy and appearance shape of diamond tools.
Henan DaKing Import & Export Co., Ltd. was founded in 2004, which is a comprehensive enterprise focusing on the production, research ,development and sales of graphite products.
