我厂在原有RJJ-9T型气体渗碳炉上进行改装,添加一套FQC-CO_2型红外线气体分析仪(广东佛山气体分析仪器厂造),实现了炉内气氛的自动控制,使渗层的碳浓度控制在所需的范围内,保证了质量。红外线分析仪的原理: 当红外线通过气体时,除了单原子气体(如Ar、Ne等)和相同原子的双原子气体(例如O_2、H_2、N_2等)外,大多数气体对红外线都有明显的吸收作用。每种气体吸收的波长各不相同,其吸收能量则与气体的含量有关。因此,只要测出红外线通过待测气体之后
I plant in the original RJJ-9T gas carburizing furnace to be modified, add a FQC-CO_2-type infrared gas analyzer (Guangdong Foshan Gas Analysis Instrument Factory), to achieve the automatic control of the furnace atmosphere, so that the infiltration layer Carbon concentration within the required control, quality assurance. Infrared analyzer principle: When the infrared rays through the gas, in addition to the monatomic gas (such as Ar, Ne, etc.) and the same atomic diatomic gases (such as O_2, H_2, N_2, etc.), most of the gas has obvious infrared Absorption. Each gas absorbs different wavelengths and its energy absorption is related to the gas content. Therefore, as long as the detected infrared through the gas under test
