1200℃ Controlled Atmosphere Furnace Nitrogen Inert Atmosphere Furnace

Introduction

A controlled atmosphere furnace is a type of furnace that allows for the introduction of one or more gases into the heating chamber, which react with the heated material, protecting it from the action of oxygen and water vapor contained in the air. These furnaces are used for a variety of applications, including heat treating, brazing, soldering, and annealing.

Controlled atmosphere furnaces are typically used when the material being heated is sensitive to oxidation or other reactions with the air. By introducing an inert or active gas into the heating chamber, the furnace can create an atmosphere that prevents these reactions from occurring. This can help to improve the quality of the finished product and reduce the risk of defects.

Controlled atmosphere furnaces are available in a variety of sizes and configurations, and can be used for a wide range of applications. They are typically more expensive than conventional furnaces, but the benefits they offer can often justify the additional cost.

Controlled atmosphere furnaces are widely used in various fields, including:

Principle

A controlled atmosphere furnace is a type of furnace that allows for the introduction of one or more gases into the heating chamber. This creates a controlled atmosphere that can protect the heated material from the action of oxygen and water vapor in the air. The gases used in controlled atmosphere furnaces can be inert, such as nitrogen and argon, or active, such as hydrogen, endothermic gas, exothermic gas, or a mixture of these gases. The specific gas or gas mixture used depends on the desired outcome of the heating process.

Warnings

Operator safety is the top important issue! Please operate the equipment with cautions. Working with inflammable& explosive or toxic gases is very dangerous, operators must take all necessary precautions before starting the equipment. Working with positive pressure inside the reactors or chambers is dangerous, operator must fellow the safety procedures strictly. Extra caution must also be taken when operating with air-reactive materials, especially under vacuum. A leak can draw air into the apparatus and cause a violent reaction to occur.
