AdTech Metallurgical Material Co,.Ltd. is a manufacturer specializing in the development of new materials, and production of graphite rings. AdTech has devoted to research and development hot-top casting series products used to hot-top casting since 2012, such as: casting thimble, distribution plate, transition plate, hat plate, graphite ring, distribution launder and other products. These products are always used cooperatively for precision molten aluminum casting. Especially matching with the air slip casting unit. Our control flow series products have been widely approved by the market.
AdTech’s graphite ring made of high purity graphite materials and produced by precision CNC equipment. It is the best choice for hot-top aluminum casting with high corrosion resistance, high geometric precision, smooth surface, long service life, low maintenance cost and non-pollution to molten aluminum. Can meet the high value-added, high-tech performance aluminum casting requirement.
Parameters of graphite rings
Overview of Adtech graphite rings:
AdTech’s graphite ring is made of high purity graphite materials and produced by precision CNC equipment. It is the best choice for hot-top aluminum casting with high corrosion resistance, high geometric precision, smooth surface, long service life, low maintenance cost, and non-pollution to molten aluminum. Can meet the high value-added, high-tech performance aluminum casting requirement.
Advantages of Adtech graphite rings:
High hardness, high erosion resistance, high geometric precision, low maintenance cost, smooth surface;
Non-peeling off, and non-pollution to molten aluminum obviously improves the quality of aluminum alloy;
Good thermal shock resistance, corrosion resistance;
Can be used for 800-1200 times casting, energy saving.
The graphite ring adopts flexible graphite tape or flexible graphite braided packing and is molded into ring products of different sizes. Suitable for hot water, high temperature, high-pressure steam, heat exchange liquid, nitrogen, organic solvent, hydrocarbon, low-temperature liquid, and other media. For compressors, pumps, valves, chemical instruments, meters, etc. Pressure (Mpa): 25 Temperature (℃): -200～850 Line speed (m/s): 30 PH value: 0～14 Graphite rings are divided into flexible graphite and carbon-graphite rings. Carbon-graphite rings are mainly used in the sealing of mechanical rotating parts. The carbon-graphite ring has the characteristics of high-temperature resistance, corrosion resistance, and wear resistance.
