Infrared temperature measurement device for high-temperature vacuum sintering furnaces and high-temperature vacuum sintering furnace

Abstract

The invention relates to an infrared temperature measurement device for high-temperature vacuum sintering furnaces, which comprises a baffling barrel, a window flange, a piece of glass, a mounting flange, a supporting plate and a temperature detector, one end of the baffling barrel is sealed to form a sealed end, the other end of the baffling barrel is open, the edge of the window flange is provided with screw holes, the mounting flange, the glass and the window flange are arranged coaxially, moreover, the glass is located between the mounting flange and the window flange, and the mounting flange and the window flange are fixed oppositely in order to fix the glass. The infrared temperature measurement device for high-temperature vacuum sintering furnaces adopted by the invention measures the temperature of the thermal field of a sintering furnace by measuring the temperature of the sealed end surface of the baffling barrel, the arrangement of the sealed end ensures that high-temperature sintering volatile matters cannot enter the baffling barrel, thus ensuring that the transmission path of an infrared ray does not have foreign matters, and thereby the temperature measurement precision of the infrared temperature detector is increased. The invention also provides a high-temperature vacuum sintering furnace.

Problems solved by technology

[0003] In high-temperature vacuum sintering furnaces, infrared temperature measurement is considered to be a more accurate technology for measuring high temperatures. In traditional sintering furnaces, infrared rays directly enter the thermal field of the sintering furnace body to measure temperature. As we all know, infrared transmission is greatly affected by the surrounding environment , such as dust and steam, so using infrared rays to directly measure the thermal field temperature of the sintering furnace body will inevitably be affected by the atmosphere inside the sintering furnace, thus affecting the accuracy of the temperature measurement
