The advantages and precautions of graphite crucible [graphite crusher]

Graphite crucible has excellent wear resistance, thermal conductivity and electrical conductivity and so on. Using this kind of graphite crucible can not only increase the service life, reduce current consumption, but also save energy and reduce system load. At the same time, graphite crucible also plays a very important role in energy saving and environmental protection. Based on the above advantages, Tianjin graphite crucible manufacturer is also a trusted manufacturer.

Graphite crucible is refined from natural high-quality graphite, which has good thermal conductivity and high temperature resistance. The thermal expansion system used in high temperature environment is not only small, but also has resistance to rapid cold and rapid heat strain, and has excellent chemical resistance to acid and alkali. Stable performance. There are many varieties and complete specifications. They are used in metallurgy, machinery, chemical, foundry and other industrial sectors. Steel smelting, non-ferrous metal and alloy smelting have also been the most widely used.

We also need to pay attention to the items when we use graphite crucibles. Graphite crucibles need to be protected from moisture. They must be carefully placed in a dry place or on a wooden frame. When handling, handle with care, and do not drop and shake. Before use, it must be heated in the drying equipment or beside the furnace to allow the temperature to gradually rise to 500°C. The crucible should be placed below the furnace mouth level to avoid the furnace lid from wearing the crucible upper mouth. The graphite crucible should be charged according to the melting amount of the crucible, not too much, and too tight to avoid expanding the crucible. The tools and crucible clamps should conform to the shape of the crucible, and the middle part of the clamp should avoid damage to the crucible by local force. When removing molten slag and coke on the inner and outer walls of the crucible, tap lightly to avoid damaging the crucible. A proper distance should be kept between the crucible and the furnace wall, and the crucible should be placed in the middle of the furnace. Excessive use of combustion aids and additives will reduce the service life of the crucible. During the final use, rotating the crucible once a week can prolong the service life of the crucible.
