There are many types of kiln equipment, and many users do not know how to choose them when purchasing. Below, we will introduce the difference between atmosphere furnaces and vacuum furnaces.
Atmosphere furnaces, as the name suggests, are capable of conveying gases such as nitrogen, hydrogen, carbon dioxide, gas, carbon monoxide, etc. to meet customers' needs for product processing. The structure of atmosphere furnaces is an improved version of ordinary muffle furnaces, which is based on muffle furnaces On the basis of this, the box is fully welded, and the sealing of the furnace body is achieved through silicone rubber. The furnace door has a cooling water system, and there are several inlet and outlet valves, pressure gauges, and vacuum pumps on the furnace body. Customers can air in and out at the same time. At the same time, it can also be vacuumed and pressurized. But the vacuum degree is certain, and the atmosphere furnaces produced in the market are generally square shaped, and the structure determines that it cannot draw a high vacuum degree
A vacuum furnace, as the name suggests, has a high vacuum degree because its structure is circular and can draw a high vacuum degree. Why do we need an atmosphere furnace with a vacuum furnace? This lies in the price aspect. Generally, the price of a vacuum furnace is above 10-20W, while the price of a small atmosphere furnace is only around 1-2W. If the vacuum degree required by the customer is not high, the atmosphere furnace can meet the customer's requirements. Furthermore, atmosphere furnaces generally allow for both inlet and outlet gases, which can also prevent air from entering the furnace and meet the requirements for product processing
