subject: A Graphite Furnace Offers Consistently High Temperatures [print this page] For high-temperature operations, using graphite elements in a furnace is certainly among the most optimal solutions. A graphite furnace is especially suited for high temperature vacuum furnaces where metals and other materials undergo processes such as sintering, debinding, heat treatment etc. Such furnaces are used for processes such as manufacturing glass and tungsten carbide that require high temperatures at a consistent rate.
Graphite blocks are also used as linings for blast furnaces where high thermal conductivity is vital. In most cases, graphite heater elements and felt or rigid graphite board insulation materials are used. However, at very high temperatures, there might be a risk of particulate contamination arising from graphite. There are also risks of carbon reaction in a furnace that comprises graphite heating elements. In such a case, a better alternative would be to use refractory metal hot zones.
By making use of graphite elements, it is possible to achieve controlled and accurate heating up to high levels. This is what makes such a furnace popular in the research sector where new materials are tested under several conditions. This particular type of furnace is also used as a very efficient vaporizer in the industrial sector.
It is very important to note that the furnace you are opting for has been manufactured by a firm that boasts years of experience in designing, manufacturing and servicing different types of furnaces and autoclaves. Also, adherence to industrial codes such as ASME is very crucial. This will not only ensure the safety of your workers and processes, but also leave you with less maintenance hassles. In case you have a clean environment process, graphite lining elements can be replaced with refractory metals to deliver optimum results.
Depending on your application, you might need to add or remove certain standard features from a furnace. A better alternative to this would be to opt for custom furnaces that give you exactly what you need. When you approach a manufacturer for a customized furnace, they would first understand your requirements and then create a 3D model to give you a part-by-part design of your entire furnace. Once this has been approved by you, they would proceed further to turn the design into a reality.
Such firms can also be your trusted partner in acquiring a sintering furnace. These furnaces are used for sintering, debinding and densification, especially of tungsten carbide. A sintering furnace can be manufactured in a variety of sizes, temperature ranges, pressures etc. Based on further requirements, it is possible to integrate cooling systems, load transfer systems, hydrogen burn-offs, and gas recovery systems too.
So, opting for a custom graphite furnace offers a world of possibilities for your process in contrast to a standard furnace.
