On December 1, 2017, a 1400 ℃ small industrial furnace was shipped. The furnace chamber of this industrial furnace is made of alumina fiber, and the furnace top construction technology is used for long-term use without collapse. Silicon carbon rods are used as heating elements, arranged on both sides of the furnace. Two small holes are opened on the furnace top according to the drawing for high-temperature rubber removal. Circulating air is added to the furnace to make the furnace temperature more uniform. The circulating air can be opened and closed at regular intervals. The essence of this furnace lies in the furnace construction technology, which subverts the traditional furnace and material production methods, ensuring long-term reliability and stability. It is used for batch heat treatment of ceramic parts by users, and can be scaled up for large-scale production in the later stage. The design of non-standard furnaces relies on continuous communication and experience accumulation. Sante Furnace Technology has accumulated a lot of experience in this area. As long as there are requirements, we will reasonably meet them
