Abstract

The invention relates to the technical field of vacuum furnace carbon potential dynamic detection and discloses a vacuum furnace carbon potential dynamic detection device and a detection method thereof, wherein the vacuum furnace carbon potential dynamic detection device comprises an inlet pipe, a carbon permeation pipe and a discharge pipe which communicate sequentially, the carbon permeation pipe is located in a hearth of the vacuum furnace, the inlet pipe is provided with a first mass flow detection piece and a heating piece used for heating standard gas in the inlet pipe, and the dischargepipe is provided with a second mass flow detection piece and a vacuum pump. According to the vacuum furnace carbon potential dynamic detection device disclosed by the invention, the carbon permeationpipe is placed in the hearth of the vacuum furnace; the content of carbon permeating into the carbon permeation pipe through the hearth is detected in real time through the first mass flow detectionpiece and the second mass flow detection piece; and therefore, the carbon potential in the vacuum furnace is calculated, the carbon potential in the hearth of the vacuum furnace can be conveniently detected in real time, the carbon potential of the hearth is adjusted according to actual needs, the percent of pass of parts is increased, and the probability that carbon black appears on the surfacesof the parts after the parts are heated is reduced.

Description

technical field [0001] The invention relates to the technical field of dynamic detection of carbon potential in a vacuum furnace, in particular to a device for dynamic detection of carbon potential in a vacuum furnace and a detection method thereof. Background technique [0002] Vacuum heat treatment has the characteristics of high efficiency, energy saving and green. It is the main promotion method for enterprise transformation and upgrading. Vacuum heat treatment, especially vacuum low-pressure carburizing heat treatment, is one of the key technologies to improve the surface hardness, fatigue strength, wear strength and life of mechanical parts. , is widely used in the surface hardening treatment of key components such as gears and bearings, and plays an important role in the upgrading of industrial products. [0003] Vacuum low pressure carburizing has many technical advantages, but the dynamic monitoring of carbon potential in the heat treatment process has not been real...
