Heat treatment furnace temperature calibration technical method

The invention relates to a heat treatment furnace temperature calibration technical method, and belongs to the field of heat treatment furnace temperature testing techniques. According to the heat treatment furnace temperature calibration technical method disclosed by the invention, the defects existing in test methods for effective heating regions of a heat treatment furnace according to a heat treatment furnace temperature test GB/T9452-2012 are overcome, and the blank of lacking of the technique of quickly and accurately testing the temperature difference of the heat treatment furnace at any time along with production within Heilongjiang province is filled up. Dual temperature sensors are adopted for direct calibration in the same temperature control region, so that the temperature errors of standard temperature sensors and working temperature sensors can be directly tested. The temperature control precision and the heat preservation precision of heat treatment products of each furnace can be monitored in time, and the quality of the heat treatment products of each furnace even each heat treatment product can be guaranteed efficiently, and a single temperature point, multiple temperature points, a single temperature control region, and multiple temperature control regions for the heating furnace can be tested arbitrarily under the conditions of unload, semi-load and full loads. The heat treatment furnace temperature calibration technical method disclosed by the invention is suitable for calibration of a box-type resistance air heating furnace, a box-type fuel gas heating furnace, and a well-type resistance air heating furnace.
