La description

Graphite crucible

The crucible is an utensil or melting tank vessels that is made of refractory material (such as clay, graphite, quartz or difficult molten metal iron, etc.).

Graphite crucible, with is special advantages and Plasticity, is widely used in the smelting area, e.g. gold smelting, silver smelting, aluminum smelting, cooper smelting, etc.

Using field:

1. often used in metallurgy, casting, mechanical, chemical and other industrial sectors

2. Widely used in smelting the alloy tool steels, nonferrous (e.g. gold,silver,aluminum, etc), nonferrous metal alloy, jewelry, glass and other suitable area.

Specification:

1.C:*9.9 %

2.Density:1.***1.*5g/cm³

3.Compressive strength :****0Mpa

Property:

-Perfect sealing performance, long service life and low maintenance

-Fine grain and high density and minimum wet ability to molten metals

-Homogeneous structure and high mechanical strength

-Excellent thermal conductivity and proper electrical conductivity .

-Frmed by isostatically pressing with the high density.

-Excellent thermal conductivity.

-Long service time : Compared with ordinary clay graphite crucible , in terms of different material can improve the life of more than 5 times ,Aluminum alloy , Zinc alloy smelting life **8 months .

-Heat resistance.

-Good thermal stability : Use the high thermal conductivity material ,compact structure , low porosity , fast heat conduction.

-High oxidation resistance :Advanced oxidation mechanism , making the graphite crucible get good protection .

-High level material and scientific design strong erosion resistance.

Operating notice:

1.The crucible should be stocked in the dry situation

2.Carry the crucible lightly

3.Warm the crucible in the drying machine or near the furnace.The warming temperature should be up to **0â„ƒ.

4.The crucible should be put under the furnace month flat.

5.When put the metal into the crucible, you should take the crucible capacity as your reference.If the crucible is too full,it will be damaged by expansion.

6.The clamps shape need as that of crucible.Avoid the concentrate stressed destroy of the crucible

7.Clean the crucible regularly and lightly.

8.The crucible should be put in the center of the furnace and leave some distance between the crucible and furnace.

9.Turn the crucible once in one week and this will help lengthen the service life.

*0.The flame should not touch the crucible directly.

*1.*4 hours constant use will make crucibles have longer service life.

The smelt soup in the crucible should be cleared out when the furnace stop working, in order to avoid molten soup solidificating and will be expanded when fire to reheat, and affect the service life of crucible or even burst.

*2.we suggest that about 2 months for crucible melting aluminum alloy (every week for melting copper alloy), hanging out to check whether there is something wrong in the surface, and clean furnace hearth as well as turn the crucible, this operation is helpful to prolong the service life of crucible.

Note:

1.We can make as your drawings or samples.

2.We can recommend you the best material as your using situation.

3.We can guarantee the best quality and delivery date.
