Acheson graphitization resistance furnace with high single-furnace productivity

Abstract

The invention discloses an Acheson graphitization resistance furnace with high single-furnace productivity. The Acheson graphitization resistance furnace comprises a processor, an infrared thermometer and a spectrum laser instrument. According to the Acheson graphitization resistance furnace with the high single-furnace productivity, the infrared thermometer transmits detected temperature information to the processor, the temperature integral calculation unit performs integral on the whole-time and whole-area temperature to obtain the heat loss amount, the spectrum laser transmits gas volume information monitored by the gas emission volume monitoring unit to the processor, and the processor performs integral calculation on the whole-time and whole-area temperature to obtain the heat loss amount. The volume of the emitted gas is integrated through the volume integration calculation unit, chemical energy taken away by the emitted gas is obtained, the processor compares the heat loss amount and the chemical energy taken away by the emitted gas with a preset heat conduction rule model through the calculation comparison unit, and the corresponding temperature distribution in the furnace body is automatically calculated. And the processor performs output adjustment on the heating point of the resistance heater through the adjustment command unit according to the temperature distribution in the furnace body, so that the temperature in the furnace body is homogenized.

Description

technical field [0001] The invention relates to a resistance furnace, in particular to an Acheson graphitized resistance furnace with high single-furnace production capacity. Background technique [0002] Acheson graphitization furnace refers to a graphitization furnace named after the inventor Acheson. The Acheson furnace was invented in 1895 and first obtained a patent in the United States. Its prototype is: in a long furnace body constructed of refractory materials, charcoal billets and pellets are filled to form a conductive furnace core. It is thermal insulation material. Conductive electrodes are arranged on the two upper end walls as the furnace head, and are connected with a power source to form a energized circuit. When the circuit is connected, the furnace core will heat up due to the resistance, so that the carbon blank will be transformed into artificial graphite after high-temperature heat treatment at a temperature of 2200-2300 °C. [0003] However, when the...

[0003] However, when the resistance furnace is working, a high temperature of more than 3000 degrees is generated inside the furnace body. The commonly used temperature measuring devices and temperature measuring methods cannot measure the actual temperature of the center well. re-speculation problem
