Product Description

 

Specifications for Graphite Silicon Carbide Crucible For Aluminum Melting :

1.Long working lifetime: its working lifetime is increased 3-5 times over normal clay-crucible due to the compact body formed under high pressure.

2.High thermal conductivity: high-density body and low apparent porosity greatly improve its heat conductivity.

3.New-style materials: new heat conduction material ensures faster heat conductivity and pollution-free product, reduces adherent slag.

4.Resistance to corrosion:better anti-corrosion than normal clay-crucible.

Q:Can the alumina crucible be heated by electromagnetic induction?
May not!A substance that can induce heat in a high frequency electromagnetic field. Only substances with high levels of iron and iron can not be hot.
Q:How to cast aluminum parts
It's simple. First put the aluminum into the graphite crucible, and the equipment is preferably a medium frequency induction furnace.
Q:Why are there too many impurities in the gravity casting products of aluminum alloy, so they can not be welded well by argon arc welding?
The filter is not added in the casting process, some slag ran in, leading to the casting surface or internal slag, leakage or air pressure testing, due to impurities, argon arc welding welding is up to where there is always staying, not fusion. The solution, first of all to choose high purity aluminum ingots, some rural plant products do not choose, are turning or cutting scrap materials in investment, not too many impurities; secondly in the casting process, increase to two times to minimize the filtering impurities.
Q:Disadvantages of graphite crucibles
The graphite crucible is much better than the traditional crucible, to say the disadvantage is that the technical requirements are very high, and the life of the imported crucible and the domestic crucible is about 3:1.
Q:What is the porcelain crucible with a small hole under it?
Is the crucible, crystalline form of natural graphite as the main raw material, plastic refractory clay as binder, refractory graphite crucible with different types of clinker with which is mainly used in smelting special alloy steel, nonferrous metals and alloy melting. Graphite crucibles are an integral part of refractories in terms of their properties and uses.
Q:Intermediate frequency induction furnace melting copper with what dry pot?
Graphite crucible, because copper is non-magnetic metal, so the circuit needs to be heated by the crucible, and then the heat of the crucible will melt the copper metal
Q:What is the difference between the indirect method Zinc Oxide and the direct law Zinc Oxide?
Zinc Oxide direct method generally used for ceramics, glaze, glass frit, and pigment industry.Zinc Oxide: the indirect method can be used in rubber, varistors, paint, phosphating solution, film, conductive materials and other industries. The direct effect of heavy metal impurity content of the products of the heavy metal content of zinc or zinc, low heavy metal content of the products, but also can be used for livestock feed, medicine, health care and other industries.
Q:What kind of equipment is needed to refine the battery lead?
It depends on what kind of output you need. If you use a lot of lead, lead into the graphite crucible, graphite crucible, and high temperature, can be melted in a piece of lead. Made of lead ingots. The dirt method I said at this time. If you need to be advanced, use the electric stove to put the graphite crucible in the electric furnace, and then the lead will melt.
Q:Graphite and diamond are elemental elements made of carbon. Why are physical properties so different?
diamondDiamond is pure carbon, graphite and chemical properties are basically the same, but the physical properties are not the same. The diamond carbon atoms is a tetrahedral solid, a Pyramid shaped structure, the overall shape of the crystal was eight, the structure is very stable, which leads to the hardness of diamond is very high. In addition to diamond almost non-conductive, hard material is the most natural, it is of poor thermal conductivity, high melting point, colorless and transparent.
Q:Is the jade pressed by the machine natural?
The first is to make amorphous jade glass material. The reagent and reagent of sodium aluminum silicate and silicate containing colouring ions, formula according to jade composition content in a crucible into the mixing and grinding after the vessel, and then placed in a muffle furnace crucible is heated to 1100 degrees Celsius, and constant temperature cooling after a few hours, you will have to take the color of jade composition of amorphous glass material. The second is made of crystal jade glass. The amorphous glass will jade colored pieces to more than 125 meshes (i.e. particle size less than 0.125 mm), 600 kg / cm on the embedded prototype, heating prefabricated 14X15 (mm) cylinder or 14X6 (mm) of the wafer; then the preformed cylinder or wafer in high-purity graphite crucible. Bake in the oven at 140 degrees Celsius for 24 hours or more; and then the pressure chamber six crucible into a compressor, the compressor start six top closure, in the long time, current power, pressure relief, can get the crystal jade glass. Synthetic emerald glass by X ray powder diffraction analysis, infrared absorption spectrum analysis, chemical composition analysis, hardness measurement, relative density (specific gravity), determination of refractive index determination, fluorescence analysis, and the data are basically consistent with natural jade.
