What are the differences between atmosphere protection furnace and vacuum furnace?
First of all, let's talk about the vacuum furnace. The meaning of the vacuum furnace is to say that the vacuum is high, because its structure is circular and can draw a high vacuum. Why do we need an atmosphere protection furnace with a vacuum furnace? It depends on the price. The general vacuum furnace is about 20W, while the small atmosphere protection furnace is only about 2W. If the customer's vacuum degree is not high, the atmosphere protection furnace can meet his needs, you say him How to choose. Furthermore, the atmosphere protection furnace generally has one side of the air inlet and the other side of the air outlet, and the protective gas can also prevent air from entering the furnace, which can fully meet the needs of commodity processing.
The atmosphere protection furnace means that it can pass the atmosphere, such as nitrogen, hydrogen, carbon dioxide, argon, carbon monoxide and other gases to meet the needs of customers for product processing. The structure of the atmosphere protection furnace is an improved version upgrade of the ordinary muffle furnace. On the basis of the muffle furnace, the box body is fully welded, and then the sealing property of the furnace body is achieved through silicone rubber. The furnace door has a cooling water system. There are several air inlet and outlet valves on the body, a pressure gauge, and a vacuum pump. The customer can take in one side and the other side. At the same time, it can be vacuumed and positive pressure can be applied. However, the degree of vacuum is certain. The atmosphere protection furnaces manufactured on the market are generally square-shaped, and the structure determines that it cannot draw a high vacuum degree.
