Detailed Description

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.

Advantages of the crucibles:

1.good thermal conductivity

2.High-temperature resistance

3.Small thermal expansion coefficient.

4.Strong corrosion resistance to acid and alkali liquid

5.Good chemical stability

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 500.

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.

10.The flame should not touch the crucible directly.

Our service:

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.
