Corrosive atmosphere will affect the high temperature furnace

Most of us are familiar with this equipment, which is used for heating in the laboratory. High temperature furnace is just a general term, in fact, in the process of continuous development, and there are a lot of subdivisions. The work of high temperature furnace is through high temperature sintering technology, the key is microwave heating, its principle is the matter under the action of microwave electron polarization, atomic polarization, interface polarization, dipole polarization and other ways, the microwave electromagnetic energy into heat energy. Then we encounter corrosive atmosphere in the use of high temperature furnace corrosive atmosphere will have what effect on the furnace? So let's talk about it

1, in the oxidized air, metal oxide and the silicon layer on the surface of the element, may cause unexpected faults, in the high temperature furnace charging should prevent metal liquid and dust splash on the element and in the melting to prevent the generation of smoke, especially to prevent flux. Also avoid compounds with a high base content. The furnace is designed for use in an oxidizing atmosphere not exceeding its high temperature, but can also operate successfully in a neutral or carburized atmosphere, and can also be used with nitrogen, argon or helium at temperatures up to 1600°C. Lowering the pressure is not recommended.

2. High temperature furnace with normal concentration of sulfur dioxide is a non-hazardous substance, but chlorine and high concentration of fluorine can even cause serious erosion of oxidizing elements, because it should be avoided that it is not recommended to use high temperature furnace to incinerate carbon-containing materials. Other high-temperature furnaces may be used for this application. When the optional intake is installed, there is a label near the intake that says "Inert gas". In fact, inert or oxidizing gases can be used, but do not use flammable or toxic gases high temperature furnace is breathable, so it is understood that gas utilization may be relatively high, there is always some air in the furnace. The residual oxygen content should be at least 1%. Erosion of the hearth can be prevented by providing an additional hearth. The consumable parts are both light ceramic fibers and high wear resistant alumina refractories.
