Vacuum furnace, the equipment has a high vacuum, because its structure is circular, can be pumped to a high vacuum. Atmosphere furnace, as its name implies, is able to ventilate the atmosphere, such as hydrogen, nitrogen, carbon dioxide, argon, carbon monoxide and other gases, to meet customer demand for product processing. The structure of the atmosphere furnace is an improved version of the ordinary muffle furnace. On the basis of the muffle furnace, the box is fully welded and sealed by silicone rubber. The door of the furnace has a cooling water system. There are several inlet and outlet valves, pressure gauges and vacuum pumps on the furnace body. Customers can enter and outlet air at the same time. At the same time, vacuum can be pumped and positive pressure can be flushed. But the vacuum degree is certain. Most of the atmosphere furnaces produced in the market are square. The structure determines that they can not get high vacuum degree.
So why do we need an atmosphere furnace when we have a vacuum furnace? This is because of the price. Generally, the price of vacuum oven is above 20W, while the price of small atmosphere oven is only about 2W. If the customer's demand for vacuum is not high, the atmosphere oven can meet its use requirements. How do you say the customer will choose? In addition, the atmosphere furnace generally intake and exhaust at the same time, through the protection of gas, can also prevent air into the furnace, can fully meet the requirements of product processing.
