- Q: How to break 40 low carbon steel smelting
- High pressure pipes are generally welded by argon arc welding, whether they are carbon steel, alloy steel or stainless steel;
- Q: Will the friction powder of the graphite sliding bearings rust?
- Graphite bearings do not charge, but if the connecting parts such as iron and other materials will rust, unless the internal device is all vacuum, which may be exposed to graphite bearings. In short, graphite products do not rust, but do not rule out inducing factors.
- 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
- Molten material with acid as flux (such as K2S, 207, etc.)Porcelain crucible: 1., heat resistance of about 1200 degrees2. suitable for K2S207 and other acidic substances melting samples3. generally can not be used for Na0H, Na202, Na2CO3 and other alkaline substances for melting flux, so as not to corrode the porcelain crucible. Porcelain crucible can not be contacted with hydrofluoric acid4. porcelain crucible can be diluted HCl boiling cleaningIron Crucible: iron does not react with sodium hydroxide, iron crucible can melt caustic soda, and iron crucible is used at 400 degrees or more. It is not economical, even if it is not melted, it also oxidizes rapidlyGraphite crucible: universal type graphite crucible and graphite crucible shaped and high pure graphite crucible three.

Technical and economic results
- Q: The use of earthy graphite?
- As refractory material: graphite and its products have the properties of high temperature resistance and high strength. They are mainly used in the metallurgical industry to make graphite crucibles. In the process of steelmaking, graphite is often used as a protective agent for steel ingots and lining of metallurgical furnaces.
- Q: Can graphite crucibles be used for plasma arc melting?
- Yes, graphite crucibles can be used for plasma arc melting. Graphite crucibles are known for their high thermal conductivity and resistance to high temperatures, which makes them suitable for use in various high-temperature applications. Plasma arc melting, which involves the use of an electric arc to generate and sustain a plasma state, requires a crucible that can withstand the intense heat generated during the process. Graphite crucibles are able to withstand these high temperatures and provide a stable and durable container for the molten material produced during plasma arc melting. Additionally, graphite crucibles offer good chemical resistance and can handle corrosive materials that may be present during plasma arc melting. Overall, graphite crucibles are a commonly used and effective choice for plasma arc melting applications.
- Q: How do you determine the appropriate crucible material for a specific application?
- To determine the appropriate crucible material for a specific application, several factors need to be considered. Firstly, it is important to evaluate the temperature range of the application. Different crucible materials have different temperature limitations. For high-temperature applications, materials such as graphite or refractory metals like tungsten or molybdenum may be suitable, while for lower temperature applications, materials like porcelain or alumina may be sufficient. Secondly, the chemical compatibility of the crucible material with the substances being used in the application needs to be assessed. Certain materials may react with specific chemicals or gases, leading to contamination or degradation of the crucible. It is crucial to select a material that is chemically inert or resistant to the substances being used. Thirdly, the thermal conductivity and thermal shock resistance of the crucible material should be taken into account. Some applications require rapid heating and cooling cycles, which can cause thermal stress on the crucible. Materials with high thermal shock resistance, such as quartz or boron nitride, may be more suitable in such cases. Moreover, the mechanical strength and durability of the crucible material should be considered. Some applications involve mechanical forces, stirring, or pouring of molten materials, which can subject the crucible to physical stress. Materials like silicon carbide or stainless steel offer good mechanical strength and can withstand such conditions. Lastly, the cost and availability of the crucible material should be considered. Some materials, such as platinum or iridium, may offer excellent performance but can be expensive and difficult to procure. It is important to strike a balance between performance and cost-effectiveness. In conclusion, determining the appropriate crucible material for a specific application requires considering factors such as temperature range, chemical compatibility, thermal conductivity and shock resistance, mechanical strength, and cost. By carefully evaluating these factors, one can select a crucible material that will meet the requirements of the application effectively.
- Q: What are the different methods of sealing a graphite crucible?
- Several methods exist for sealing a graphite crucible, each with its own advantages and considerations. One commonly used method involves the application of a graphite cement or adhesive to the joints or seams of the crucible, which is then allowed to dry or cure. This method ensures a strong and durable seal that remains intact even during high-temperature applications. However, it can be time-consuming and may require periodic reapplication. Another approach is to employ a graphite crucible cover or lid, placed on top of the crucible to create a seal. This method is relatively quick and easy to implement. However, it may not provide as tight of a seal as other methods, necessitating proper alignment and fitting of the lid or cover. In some cases, a combination of mechanical fasteners like bolts or clamps, along with a high-temperature gasket material, can be used to seal the crucible. This involves securing the crucible joints with the fasteners and applying gasket material for a tight seal. This method ensures a reliable and secure seal, even under high-temperature conditions. However, it may demand additional time and effort for installation and removal of the fasteners and gasket material. It is crucial to consider the specific application and requirements when selecting the appropriate sealing method for a graphite crucible. Factors such as operating temperature, duration, and the type of material being processed should be taken into account. Consulting the manufacturer's guidelines and instructions for the specific crucible being used is recommended to ensure proper sealing techniques are followed.
- Q: Application of ceramic fiber module in gas crucible furnace
- From the way of heating, the crucible furnace has gas, fuel, electricity, coal, coke and so on. The life of the furnace crucible depends on the insulation material.
