Clients can avail these graphite crucibles in various varieties.

Attributes:

High density graphite casting crucibles find wide applications in vacuum/ inert atmosphere furnaces are available Almost similar to grade 2 but cheaper by fifteen to twenty percent. Chain makers mainly demand economical and high quality graphite crucibles

In general, the inspection work of graphite crucible before use should mainly do the following:

1. First, check the graphite crucible for cracks before work. If there is no crack, the graphite crucible should be heated to 600 ° C or more and fully dried.

2. There should be no water around the furnace and in the pit in front of the furnace, and irrelevant objects should not be stacked near the graphite crucible.

3. Strictly inspect the furnace charge for explosives. The furnace charge must be preheated and dry, and the graphite crucible must be slow.

Before using the graphite crucible, be sure to do the above points, otherwise it is very likely to cause the graphite crucible to explode during use.

The main purpose of the graphite crucible is to heat the experimental material that needs to be heated. Generally, the graphite crucible is used to heat the solid material in the experiment. The graphite crucible has a variety of models. The crucible can be selected according to the number and type of materials to be heated and the degree of thermal expansion. model. In general, when using graphite crucibles, we must pay attention not to fill the crucible with heated materials, which is very dangerous, not only easily cause experimental accidents, but also have a great impact on the life of the graphite crucible. In addition, it should be noted that under normal circumstances the crucible must be heated to four or five Baidu, at this time must not place graphite crucible or touch the graphite crucible by hand, this is very dangerous. Graphite crucible for glass,graphite crucible with hole,graphite crucible images,graphite crucible set,graphite crucible suppliers

1. The requirements for the fire resistance of graphite crucibles are very high. Therefore, we must require the fire resistance of the raw materials of graphite crucibles, so that the graphite crucibles can be used more safely;

2. We often use graphite crucibles in chemical smelting that is more corrosive, so the chemical stability of graphite crucibles is also very important, so that corrosion can be reduced;

3. The hardness and toughness of graphite crucible are also factors we need to consider, to avoid brittle fracture of graphite crucible in use.

The above is the material selection method we should adopt when making graphite crucibles. Only by selecting materials according to the above standards, can graphite crucibles be able to give full play to its performance.
