- Quality stability: Under high pressure and quality guarantee system, it will fully ensure the stability of quality.
- High heat Conduction: High content of fixed carbon ensures the good heat conduction. It also shortens the time of dissolution. Furthermore, itremarkably reduces the energy consumption.
- Thermal stability: According to the quench acute thermal using conditions of graphite crucible. It is designedto ensure the reliability of product quality.
The gold melting crucible is mainly made of crystalline natural graphite. The Graphite crucible has good thermal conductivity and high temperature resistance. It has strong corrosion resistance to acid and alkaline solution and has excellent chemical stability. Quartz crucible is mainly made of High purity quartz sand, it has the advantages of high purity, high temperature resistance, good heat preservation, energy saving, stable quality, etc. Because of their excellent performance, graphite crucible and quartz crucible are widely used in the metallurgy, foundry, machinery, chemical and other industrial sectors for the smelting of alloy tool steel and the smelting of non-ferrous metals and their alloys.
Features for graphite crucible
Graphite crucible has a long service life. Also, it has a certain strain resistance to the thermal shock and quenching. The thermal stability is well.
Besides, It is according to the using conditions of gold melting crucible snap heat and cold. It is well corrosion resistance and impact resistance performance. As a result, it can ensure the reliability of product quality.
Excellently, it resistance to strong acid and strong alkali.
Graphite Crucible & Quartz Crucible
Graphite gold melting crucible is a container applied to hold metal for smelting in a furnace. And it’s available to smelt metals under the extreme temperatures. Hence the crucible material must have a much higher melting point than the melted metal and also it must have good strength even when white hot.
Besides, graphite crucible for gold melting can withstand the high temperature, and has good resistance to chemical erosions and thermal shock.
It is generally applied for melting precious metal such as gold melting, silver melting, platinum melting, etc. Additionally, graphite crucible is also suitable for aluminum melting, copper, stainless steel and etc.
Graphite crucible and quartz crucible should be stored in dry place and do not get it wet. After drying the crucible, don’t make it touch with water. Also be careful not to give a mechanical impact force, not from a fall or impact.
Under high pressure and quality guarantee system, it will fully ensure the stability of quality.
High Heat Conduction
High content of fixed carbon ensures the good heat conduction. It also shortens the time of dissolution. Furthermore, itremarkably reducesthe energy consumption.
According to the quench acute thermal using conditions of graphite crucible. It is designedto ensure the reliability of product quality.
Even and fine basic design will delay the erosion of the graphite crucibleand quartz crucible.
Graphite crucible can bear high thermal impact, so can carry out all process.
The adding of special materials will greatly improve the quality of graphite crucibleand quartz crucible for gold melting. Especially its index of acid resistance. And will prolong the service life of crucible.
Control of Metal Pollution
The component of material is under strict control. It ensures that graphite crucible and quartz crucible will not pollute the metals when dissolving.
Using in High Temperature Process
thermal expansion coefficient is small. It has resistance strain performance to hot and cold. Strong corrosion resistance to the acid and alkali solution;
Graphite crucibles are mainly used to smelt steel, iron and other non-ferrous metals such as copper, brass, zinc and lead and their alloys.It is available in a variety of sizes ranging from 250g to 500kg.
It is used to refine high-purity metals, as well as to be used to melt small amounts of precious metals such as gold, silver, platinum and high purity metals or high melting point metals and oxides.
Quartz crucible has good heat stability and can be directly placed on the flame to heat. As quartz is brittle and easy to break, so it must be very careful when using it.
Non-ferrous and ferrous metals melting.
Precious metal melting, like gold, sliver and platinum, etc.
Semiconductor material melting.
Specialized steel, iron and copper melting.
Metal alloy melting, like aluminum alloy, zinc alloy and copper alloy,etc.
Welding diamond/carbide saw blade, diamond cutting tools, grinding tools and drilling welding.
Carbide cutting tools for machining welding. Such as turning and milling cutter welding.
Mining tools welding, such as pillar gear drill bits, dovetail coal drill bits, drill rods riveting, all kinds of shearer.
The welding of wood working tools, such as woodworking planer, milling and drill.
Hot forming for all kinds of standard parts, fasteners, machinery parts, hardware tools and straight shank twist drill. Metal annealing, such as: tensile steel; wire, nail wire heating and stainless steel annealed.
What is a melting crucible made of?
Modern crucibles may be small laboratory utensils for conducting high-temperature chemical reactions and analyses or large industrial vessels for melting and calcining metal and ore; they may be made of clay, graphite, porcelain, or a relatively infusible metal.
Can you melt brass in a steel crucible?
Yes, but you will want to get a new crucible for each metal you melt. Cast iron has a higher melting point than brass, so if your furnace can do cast, then brass should be a piece of cake. Brass is a mix of copper and zinc.
What does a crucible symbolize?
The Doll in the Proctor’s house is a traditional symbol of voodoo and witchcraft. It symbolizes the transformation of good to evil. Nowadays, the doll represents childhood innocence and brings happiness.
What is the purpose of a crucible?
In chemistry, a crucible is a kind of laboratory equipment that is usually a cup, made of porcelain or non-reactive metal, used to heat chemical compounds to very high temperatures using a bunsen burner. One of the earliest uses of platinum was as a material in crucibles.
