Combined heat treatment furnace temperature measuring rack and application method

Abstract

The invention provides a combined heat treatment furnace temperature measuring rack and an application method. The temperature measuring rack is formed by distributing a plurality of component units, wherein each component unit comprises a sleeve, a connecting rod and a base which are connected in sequence from the upper part to the lower part. When in use, the quantity of the component units is determined according to the size of an effective heating zone of a heat treatment furnace and the quantity of testing sensors; the connected component units are distributed according to size requirements, so as to ensure that the upper end point of each sleeve is positioned in the peak of the required effective heating zone; when the effective heating zone is tested, testing ends of the testing sensors are fixed to the end points or the midpoints of the sleeves, and a geometric space defined by the testing ends of all the sensors is just the measuring position of the required effective heating zone; after use, the component units are decomposed and stored for standby application. The combined heat treatment furnace temperature measuring rack is applicable to all heat treatment equipment with cuboid effective heating zones, and is convenient and fast to use.

Description

technical field [0001] The invention relates to a temperature measuring frame for a heat treatment furnace and a use method thereof. The invention is suitable for box furnaces, live bottom furnaces and other heat treatment equipment whose effective heating area is a cuboid, and is used for measuring the effective heating area. Background technique [0002] The effective heating area is also called the working area, which refers to the allowable charging space in the furnace determined by temperature detection to meet the heat treatment process and temperature uniformity requirements. In "Thermal Process Quality Control" (GJB509B), "Measurement Method for Effective Heating Zone of Aeronautical Parts Heat Treatment Furnace" (HB5425), "High Temperature Measurement" (AMS2750) and other domestic and foreign standards, the measurement method and process of effective heating zone are carried out. related regulations. [0003] No matter what method and process is used, the temperat...

AI Technical Summary

Problems solved by technology

[0007] 1. Welding is time-consuming and material-consuming. When the volume of the heating furnace is large, in order to ensure its strength, it is necessary to weld many reinforcing ribs and a large amount of steel;

[0008] 2. Due to the large volume of the traditional cuboid temperature measuring rack, it is necessary to prepare a storage location for it, and it is difficult to carry it when using it;

[0009] 3. Due to the large volume of the traditional cuboid temperature measuring frame, each steel pipe (rod) is relatively long, so it is easily affected by denaturation and welding stress, resulting in serious deformation and deformation after a period of use under high temperature conditions, eventually It needs to be reprocessed and manufactured, which is a huge waste
