Clay Pot Copper Melting Pot on sale

1.Introduction

     The material of graphite crucible  can be divided into artificial graphite,clay bonded graphite, and carbon bonded graphite.Artificial graphite crucible is made of graphite electrode as material and made out.

     Clay bonded graphite, the main ingredient is natural crystal graphite and clay Now only used in small amount of high-temperature melting of cast iron, cast steel melting and melting of precious metals.

     Carbon bonded graphite, the main ingredient is natural crystal graphite and silicon carbide. Mainly used in  the melting of  the majority of non-ferrous metals such as copper alloy and aluminum alloy.

2.Property

     Graphite crucible with good thermal conductivity and high temperature resistance, at high temperature in use process, small thermal expansion coefficient, the thermal shock, quenching has certain strain resistance. Of acid and alkaline solution of strong corrosion resistance, excellent chemical stability.

3. Function

     Graphite crucible, because has more excellent performance, so in metallurgy, casting, machinery, chemical and other industries, has been widely used in alloy tool steel smelting and smelting of nonferrous metals and their alloys. And has a good technical and economic effect.

 1.Crucible need to stored in ventilated and dry environment, avoid moisture to affected application.

2.Crucible should be handling gently, do not roll, in case not to damage the protective layer on the surface of crucible.

3.Before use,need baking crucible,the baking temperature from low to high slowly heat up, and constantly flipping crucible and let its uniform heat, eliminate moisture , preheating temperature gradually rises to more than 500℃ (if preheating undeserved, will lead to blowout, spalling,this not belong to quality problems, won’t be refund).

4.Crucible furnace need mating with crucible, the gap of around need to meet the requirements, furnace cover can't pressure on the crucible.

5.Need to avoid flame spray on the side of crucible, should be sprayed to the crucible bottom.

6.When feeding raw material, should be slowly, big size material don’t install too much and tight,avoid to crack crucible.

7.Crucible tongs need suitable with crucible, to avoid damage crucible.

8.Crucible better be continuous used, in order better to play its high performance.

9.Need to periodic rotation when using crucible, for heated evenly, prolonged use.

10.When remove the slag and stick cokes of crucible, should tap gently, to avoid damage to the crucible.
