What is Hydrogen Atmosphere Furnace?
Hydrogen atmosphere furnace is a kind of equipment that can carry out heat treatment of materials under high temperature and hydrogen atmospheres.
It is mainly through the high-temperature and atmosphere control change the physical and chemical properties of the material, and then realize the material modification, and improve its quality and performance.
Recently, the orders for hydrogen atmosphere furnaces are steadily increased. This proves once again that hydrogen atmosphere furnace, as one of the hot-selling products of Brother Furnace, has won the trust of customers with its high quality and performance.
We also would like to take this opportunity to introduce hydrogen atmosphere furnace to you in detail again, to help you understand it better.
What Materials Require Hydrogen Atmosphere Furnaces?
Hydrogen atmosphere furnace is mainly used in metallurgy, the chemical industry, ceramics, electronics, and other fields. It is the ideal product for atmosphere sintering and reduction in colleges and universities, scientific research institutes, industrial enterprises and so on.
1. Metal Materials
Hydrogen atmosphere furnace can be used for the sintering and processing of metal materials. At high temperatures, the metal powder can realize the combination between particles through the sintering process to form dense metal lumps.
This atmosphere furnace can increase the strength and hardness of metal materials and improve their physical and chemical properties, which are widely used in aerospace, automobile manufacturing, electronic equipment and other fields.
2. Ceramic Materials
Hydrogen atmosphere furnace is also widely used in the preparation of ceramic materials. It can improve the hardness, wear resistance, and heat resistance of ceramic materials, so that they have a wider range of applications, such as building materials, electronic ceramics, refractory materials and so on.
Through the process, the ceramic powder can realize the combination of particles and form a dense ceramic body.
3. Powder Metallurgy
Hydrogen atmosphere furnace also has important applications in the field of powder metallurgy.
Powder metallurgy is a method of smelting metal powders into desired parts through the sintering process. Hydrogen atmosphere furnace can provide a high temperature and inert atmosphere, so that the metal powder in the sintering process can be melted and combined, and ultimately formed into the desired shape and properties of the metal parts.
Powder metallurgy has important applications in the manufacture of automotive parts tools, aerospace parts and so on.
Advantages of Using Hydrogen
1. Strong reducing property: Hydrogen is extremely reducing and can effectively remove impurities from metal oxides, resulting in a purer metal or alloy. This is especially important for metal products that require high purity and high densities.
2. Improve the sintering quality: Sintering in hydrogen can improve the densification and mechanical properties of metal materials, reduce porosity, and thus enhance the strength and toughness of materials.
3. High sintering efficiency: the excellent thermal conductivity of hydrogen can rapidly transfer heat and shorten the sintering time. Helps to improve the efficiency of the sintering process.
4. Reduction of impurities: hydrogen can react with certain impurities and convert them into gaseous substances out of the furnace, reducing the impurity content and structural defects in the material and improving the uniformity and consistency of the product.
5. Less Pollution: Hydrogen generates water vapor after combustion and does not produce greenhouse gases such as carbon dioxide. It is more environmentally friendly than using hydrocarbons as a reducing gas. The use of hydrogen as a reducing atmosphere helps companies realize green production.
Product Components

Precautions
When using a hydrogen atmosphere furnace from Brother Furnace, following these recommendations will help you use the equipment more safely and efficiently.
● After the hydrogen atmosphere furnace has been used, the temperature should be lowered slowly. The recommended cooling rate is 10℃/min.
● It is forbidden to heat any flammable or explosive substances or to introduce flammable or explosive gases.
● After use, the furnace lining may develop small cracks on the surface. This is normal. It does not affect the service life of the furnace.
● Before heating, be sure to place the stopper bricks of the hydrogen atmosphere furnace inside the furnace frame.
● It is strictly prohibited to dismantle the furnace chamber and distribution box at will to avoid circuit failure.
● Recommend that the temperature inside the hydrogen furnace be cooled to below 300 degrees before opening the door, otherwise, the cold air will easily cause thermal shock to the refractory material, which will lead to cracks in the furnace lining.
● It is recommended to keep it clean frequently. Regularly check whether the contact of the electrical connection part of the temperature control system is favorable.
● The input power must not exceed the rated power and the furnace temperature must not exceed the rated temperature.
