1.High thermal conductivity. silicon carbide graphite crucibles have high-density body and low apparent porosity greatly improve its heat conductivity.
2.Long working life
Normally 6-13months,even longer under good maintenance.Its working
life is increased more than 5 times over clay crucible.
3.New-style materials. silicon carbide graphite crucibles new heat conduction material ensures faster heat conductivity and reduces adherent slag.
4.Resistance to corrosion.Better anti-corrosion than clay crucibles.
5.Resistance to oxidation. Advanced process dramatically improves its oxidation resistance,which ensures persistent heat conductivity and long working lifetime.
6.High compression strength. silicon carbide graphite crucibles high-density body and logical structure define better compression property.
7.Saving metal. The crucible contains the prevention of oxidation in order to saving metal
8.Eco-friendly. Energy-efficient and pollution-free.It not only ensures the purity of its metal
products,but also benefits to environmental sustainability.
9.Wide Application.silicon carbide graphite cruciblescan be used in electric furnace,gas furnace,oil furnace and induction furnace.
Pay Attention To When you use
1.Graphite crucibles 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 crucibe
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.
