真空熱風爐的起源?什麼是真空狀態?

真空熱風爐成都收賬基本原理誕生於1972年蘇黎士理工大學。1975年日本TAKUMA公司據此原理開發出瞭真空熱風爐，並獲發明專利，後來逐步在全世界得到推廣，此技術得到韓國企業成都找人公司研制與發展，相繼出現韓國TAKUMA,
The basic principle of vacuum hot stove was born in 1972 at Zurich University of science and technology. In 1975, Japan TAKUMA Company developed a vacuum hot blast stove based on this principle, which was patented for invention. Later, it was gradually popularized all over the world. This technology was developed and developed by Korean enterprises, and Korean TAKUMA appeared one after another. 國內在80年代後期就有一些廠傢研制真空熱風爐，但由於技術方面成都收賬問題，主要是無法解決熱風爐在密封收賬真空狀態下水和鐵發生電化學反應生成不相溶氣體導致真空度不斷下降成都找人公司問題，一直未得到推廣。90年代韓國的生產企業相對進入中國市場，後期約在2003年國內的熱風爐廠傢開始生產真空熱風爐。
In the late 环氧地坪1980s, some domestic manufacturers developed vacuum hot blast stoves. However, d印花地坪ue to technical problems, it is mainly impossible to solve the problem that water and iron react electrochemically to produce incompatible gases in sealed vacuum, resulting in the continuous decrease of vacuum, which has not been promoted. In the 1990s, Korean manufacturers entered the Chinese market relatively. Later in 2003, domestic hot stove manufacturers began to produce vacuum hot stoves.
真空狀態並不是指絕對壓力為零，隻要比外部氣壓低，都可以稱之為“真空”.例如：真空熱風爐運行時鍋殼內被調試為真空狀態，並維持-375pxHg--76mmHg之間。
The vacuum state does not mean that the absolute pressure is zero, so long as it is lower than the external pressure, it can be called "vacuum". For example, when the vacuum hot stove is running, the shell is debugged as a vacuum state and maintained between - 375pxHg and 76mmHg.
