Infrared temperature measuring device and heat treatment equipment

Abstract

The invention discloses an infrared temperature measuring device and heat treatment equipment, and relates to the technical field of temperature measurement and protection. The infrared temperature measuring device comprises an infrared imager, a window assembly and a protective sleeve, and is characterized in that an installation base is internally provided with a temperature measuring cavity, afirst heat insulation layer is installed in the temperature measuring cavity, the infrared imager is detachable installed in the protective sleeve, the protective sleeve extends into the temperature measuring cavity and is fixedly connected with the installation base, a gas inlet pipe is installed in the installation base, the outlet of the gas inlet pipe is arranged at the side, which is away from the protective sleeve, of the first heat insulation layer, the gas inlet pipe can be provided for inputting an inert gas so as to form a heat insulation gas curtain at the surface of the first heatinsulation layer. Compared with the prior art, the infrared temperature measuring device provided by the invention adopts the infrared imager installed in the protective sleeve and the gas inlet pipecapable of forming the heat insulation gas curtain, so that the infrared imager can be ensured to operate normally so as to perform temperature measurement on the whole profile of the workpiece, the temperature measurement efficiency is high, the temperature measurement data is accurate, and the practicability is high.

Description

technical field [0001] The invention relates to the technical field of temperature measurement and protection, in particular to an infrared temperature measurement device and heat treatment equipment. Background technique [0002] Metal heat treatment is to heat a metal workpiece in a certain medium to a suitable temperature, and keep it at this temperature for a certain period of time, then cool it at a different speed, and control its performance by changing the surface or internal structure of the metal material. kind of craft. [0003] At present, the temperature measurement of heat treatment equipment uses k-type thermocouples or load armored thermocouples to measure the temperature of the atmosphere of the equipment or a certain point or points of the heat-treated workpiece to achieve temperature control. However, during the actual heat treatment process of the workpiece or the mold in the furnace, due to the different size and shape of the workpiece, the loading posi...

Problems solved by technology

However, during the actual heat treatment process of workpieces or molds in the furnace, due to the different sizes, shapes, loading positions and loading weights of the workpieces, the temperature at different positions of the workpieces will be significantly different, and the load galvanic couple can only measure the measured This will lead to differences in the quality of each position of the mold after heat treatment, especially for the key parts of the key complex mold. During heating, the actual temperature is too high to cause tissue growth, and the actual temperature is too low to reach the target temperature, resulting in Insufficient dissolution; the temperature of key parts cannot be controlled to control the cooling rate during cooling, resulting in performance differences of key parts
