- Q:Rotary kiln dust removal, zinc coated sand and Zinc Oxide Technology
- Using a simple stove, will prepare zinc into Zinc Oxide: Zinc in graphite crucible, with coke heating outside heated zinc sublimation after reaction with oxygen to generate Zinc Oxide in the air above a collection system using tinplate can collect content of more than 99% Zinc Oxide.
- Q:Can a graphite crucible be used for nickel melting?
- Yes, a graphite crucible can be used for nickel melting. Graphite is a suitable material for high-temperature applications and has good resistance to chemical reactions with nickel. It can withstand the high temperatures required for nickel melting without melting or reacting with the metal, making it an ideal choice for this purpose.
- Q:Can a graphite crucible be used for non-ferrous metals?
- Indeed, non-ferrous metals can absolutely be melted using a graphite crucible. Foundries and laboratories frequently utilize graphite crucibles for the purpose of melting and casting non-ferrous metals like gold, silver, copper, aluminum, and zinc. The reason graphite is widely favored for high-temperature applications is due to its exceptional thermal conductivity and high melting point. It possesses the ability to withstand the extreme heat required to melt non-ferrous metals, all the while avoiding any possibility of melting or chemically reacting with the molten metal. Furthermore, graphite crucibles exhibit impressive resistance to thermal shock and are relatively manageable and easy to clean. As a result, they are the preferred choice in various industries when it comes to melting non-ferrous metals.
- 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:Can a graphite crucible be used for silicon melting?
- No, a graphite crucible cannot be used for silicon melting because silicon has a high affinity for carbon and would react with the graphite crucible, leading to contamination of the silicon melt.
- Q:What are the advantages of a graphite furnace atomizer compared to a flame atomizer?
- Graphite furnace atomic device is a type of system will be placed in the pipe wall, graphite platform, carbon sample holes or graphite crucible with electric heating to a high temperature to achieve atomization. Tubular graphite furnace is the most commonly used atomization device.
- Q:What is the use of an iron crucible?
- Because it is more able to withstand high temperatures than glass. When used, the crucible is usually placed diagonally on the crucible to prevent the heat from jumping out and allowing the air to pass in and out freely for possible oxidation. 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.
- Q:What are the common uses of graphite?
- As a conductive material of graphite in the electrical industry widely used as electrode, brush, carbon, carbon nanotubes, mercury rectifier cathode, graphite gasket, telephone parts, TV tube coating etc.. The most widely application of graphite electrode in smelting, alloy steel, iron alloy, graphite electrode, the strong current through the melting zone, the arc electrode into the electric furnace, the electrical energy into heat, the temperature rises to 2000 degrees, so as to achieve the purpose of melting or reaction. In addition, in the electrolysis of metal, magnesium, aluminum and sodium, the anode of the electrolytic cell is also made of graphite electrode. The resistance furnace for carborundum is also made of graphite electrode as furnace head conducting material.
- Q:Can a graphite crucible be used for ceramic glazing?
- No, a graphite crucible cannot be used for ceramic glazing. Graphite is a form of carbon that has a high melting point and is commonly used for melting metals. However, when it comes to ceramic glazing, the crucible needs to withstand high temperatures and provide a non-reactive environment for the glaze to properly adhere to the ceramic. Ceramic glazes require specific materials such as porcelain or stoneware crucibles that can withstand the high firing temperatures and do not react with the glaze. Graphite crucibles may not only react with the glaze, but they may also contaminate the glaze, resulting in poor quality or failed glazing results. Therefore, it is important to use the appropriate crucible materials specifically designed for ceramic glazing processes.
- Q:How do you determine the appropriate crucible pouring lip for a specific application?
- The appropriate crucible pouring lip for a specific application is usually determined by considering factors such as the desired pouring speed, the material being poured, the temperature, and the required precision. It is important to choose a lip design that allows for controlled and accurate pouring without spilling or splashing, while also considering the ease of handling and the size of the crucible.
