SiC Graphite Crucibles For Melting Aluminium And Copper, Brass
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.
5.Resistance to oxidation: advanced process dramatically improves its oxidation resistance, which ensures persistent heat conductivity and long working lifetime.
6.High-strength: high-density body and logical structure make the product better compression property.
7.Eco-friendly: energy-efficient and pollution-free, not only ensure metal product purity, but also ensure sustainable development on environment.
8.Multi-function: Can be used in induction graphite crucible furnace
Type of Crucible
Type S: Clay graphite crucible
Type D: Isostatic pressing graphite crucible

- Q:Graphite electrode, high temperature resistant oxidation coating, formulation technology
- Graphite crucible through anti-oxidation coating impregnation besmear after treatment, the ZS-1011 high temperature graphite coating liquid can penetrate into the pores of graphite crucible, the residual air emptying graphite crucible, forming a layer of antioxidant protective film on the graphite crucible and graphite crucible surface porosity. It is this layer of protective film can effectively isolate the air in direct contact with the graphite crucible and graphite crucible by reaction of the Chi Sheng Wei Hua coating impregnation treatment, no cracking, shedding in high temperature changes, which can effectively retard the oxidation of graphite crucible, prolong the service life of the graphite crucible.
- Q:To sum up the different uses (and causes) of various crucibles in ChemistryQuartz glass crucibles, for examplealumina crucibleGlass crucibles, iron crucibles, and the like are different and should be noted
- 2, can not touch the HF and, at high temperature, easy and caustic effects of carbonate and alkali metal.3. quartz crucibles are suitable for melting samples with K2S2O7, KHSO4 as flux, and treating samples with Na2S207 (first drying at 212 degrees) as flux4. quartz brittle, easy to break, use should pay attention to5. except for HF, ordinary dilute inorganic acid can be used as cleaning solutionAlumina crucible: 1. corundum crucible is made of porous fused alumina, which is compact and resistant to melting
- 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:What's the difference between crucible furnace and non crucible furnace in die casting industry?
- The stove is not without crucible furnace crucible said above, the molten pool is built by the whole plate, high aluminum refractory castable, heating with resistance wire, silicon carbide, top mounted combustion heating machine, dipping type silicon carbide rod. The furnace has a life expectancy of about 3 or 5 years.
- Q:When decomposing iron ore, why should it be carried out at low temperature?
- Because the iron ore inside the FeCl3, Yi Shenghua, most of the more than 100 degrees Celsius will evaporate into the air, so it is low temperature decomposition.
- Q:Which is a good quality graphite crucible?
- Because the bottom of the pot is very small, it usually needs to be placed on the clay triangle to heat it directly. The crucible can be placed on the iron tripod with either positive or oblique directions, and can be placed on the basis of the requirements of the experiment. When the crucible is heated, it cannot be immediately placed on a cold metal table to prevent it from breaking due to rapid cooling. It should not be placed on the wooden table immediately so as not to spoil the table or cause fire. The correct method is to cool the metal on the tripod or to let it cool slowly on the asbestos net. For crucible purposes, see the crucible tongs. The relevant information from the supply of silicon carbide crucible dachengxian Tianjin high silicon carbide crucible crucible factory released using the latest international technology of isostatic pressing method and strict quality assurance inspection system, selection of high quality refractory raw materials, high-tech to develop a new generation of high quality silicon carbide crucible, this product has a large volume density, high temperature resistance, fast heat, acid and alkali resistance, high temperature strength, oxidation resistance and high service life is 3 times that of the clay graphite crucible.
- Q:How to improve the service life of graphite crucible
- From the product point of view:1., raw materials are chosen from natural graphite to ensure that the graphite is not easily oxidized;2. cold isostatic pressing process is adopted to ensure high density and strength of crucible;3., the crucible surface high temperature, low temperature protection glaze layer, isolated oxygen and graphite contact contact;From the production point of view:1., scientific warming, to prevent cold, hot;2. add proper and proper amount of refining agent;3. do not stop the furnace abnormally;
- Q:How to extract pure silver from sundry Silver
- In a dilute nitric acid solution of 10% concentration, silver reacts with nitric acid to produce silver nitrate.300 kg. This dilute nitric acid solution can treat 4000 kilograms of silver glass and become silver nitrate solution
- 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:What special attention should be paid to the use of graphite crucible in vacuum induction melting of titanium alloy?
- Titanium alloy smelting, no one using graphite crucible
