The advantages of graphite elements commonly used in vacuum furnaces：1. Graphite has good high temperature strength. At room temperature, the strength of graphite is far worse than that of metals, but its strength gradually increases as the temperature rises, which will exceed all oxides and metals;
Recently, Kejia furnace company launched a very popular dental fast sintering furnace. A maximum of 10 crowns can be placed on this furnace. The whole process can be completed in about 40 minutes from booting to the tray lowering. After it is kept warm at the highest temperature, the tray is opened a little bit, and then the tray falls down for about four to five hundred degrees, and then it can be taken out after a while.
Semiconductor technology is one of the complex technologies that human science and technology has developed so far. It is known as the jewel in the crown of modern manufacturing. The world’s complex physical and chemical theories and sophisticated equipment can be seen on the production lines of the semiconductor industry. What we want to talk about is the beautiful things that happen when vacuum encounters chemical vapor deposition.
The vacuum furnace uses a vacuum system to make the pressure in the furnace chamber less than a standard atmospheric pressure. The furnace chamber achieves a vacuum state, and then heats in the vacuum state. The vacuum heat treatment furnace can effectively avoid the disadvantages of heat treatment in the air
Today I will share with you the annealing process of a bell-type annealing furnace.Bell annealing furnaces generally use hydrogen or hydrogen-nitrogen mixed gas as the protective gas, but hydrogen has better thermal conductivity than hydrogen-nitrogen, and high-standard hydrogen has a stronger decarburization ability than hydrogen-nitrogen.
