Energy saving measures for controlled atmosphere furnaces

[wyd1014]

Compared with ordinary heat treatment furnaces, the use of controlled atmosphere consumes additional energy. This is mainly caused by the preparation atmosphere, the heating of the atmosphere introduced into the furnace, and the increase in heat loss from the furnace wall caused by hydrogenation in the furnace wall.https://www.vacfurnace.com/technology-frontiers/vacuum-brazing-of-aluminum-alloys-and-filler-metals/Vacuum heat treatment quality inspection When selecting an atmosphere, on the premise of meeting process requirements, the amount of energy consumed in preparing the atmosphere should be fully considered. At present, there are many types of atmospheres used in production practice, such as: exothermic atmosphere, https://www.vacfurnace.com/technology-frontiers/effect-of-alloying-elements-on-vacuum-tempering-of-quenched-steel/endothermic atmosphere, ammonia decomposition gas, charcoal gas, hydrogen, argon-helium and nitrogen-based atmosphere, etc.Effect of vacuum sintering process on the properties of cemented carbide The emergence of endothermic atmosphere in the early 1940s promoted the rapid development of controlled atmosphere heat treatment. It is the most used and versatile atmosphere. The structure of the generating device for this kind of atmosphere is relatively complex, and the preparation process consumes a large amount of raw material gas and external heat energy.Powder metallurgy stainless steel vacuum sintering process In the 1970s, due to the energy crisis, the cost of endothermic atmospheres increased with the continuous increase in fuel prices. https://www.vacfurnace.com/technology-frontiers/vacuum-brazing-repair-method-for-cracks/In addition, there were safety issues when using them at low temperatures. People began to explore new alternative atmospheres. Therefore, the "prepared" nitrogen-based atmosphere developed in recent years has attracted more and more attention.Carburizing process and carburized steelhttps://www.vacfurnace.com/technology-frontiers/vacuum-brazing-of-ceramic-and-metal-materials/

oh my, furnaces and hot sheet. Bugger off!

He should go explore a different atmosphere.
