High temperature experimental electric furnaceThe working principle is mainly based on resistance heating. Heating elements are usually made of high resistance alloy materials (such as nickel chromium alloy, silicon carbon rod, silicon molybdenum rod, etc.), which have good high temperature resistance and conductivity. When current passes through the heating element, due to the presence of resistance, electrical energy is converted into thermal energy, causing the heating element to heat up. The heat generated by the heating element is transferred to the materials inside the furnace through thermal radiation, conduction, and convection, achieving the desired high temperature environment.
Based on core parameters and application scenarios,High temperature experimental electric furnaceIt can be divided into the following types:
Classified by temperature range:
Medium high temperature furnace (1000-1400 ℃): suitable for sintering solid oxide fuel cell (SOFC) electrolytes (such as YSZ), simulating high-temperature molten glass solidification process for nuclear waste treatment, catalyst preparation, etc.
Ultra high temperature furnace (1800-2600 ℃): using special heating elements such as lanthanum chromate, suitable for the preparation of refractory compounds and high-temperature physical property testing.
Classified by furnace shape:
Box type resistance furnace: simple structure, easy operation, suitable for heat treatment of various materials.
Tube type resistance furnace: suitable for heat treatment of long strip samples, such as rods, tubes, etc.
Classified by operating procedures:
Manual programming of resistance furnace: It is necessary to manually set the heating, insulation, and cooling programs.
Intelligent Control Resistance Furnace: Equipped with advanced control system, it can achieve multi-stage programmable heating and real-time data recording.
Classified by atmospheric conditions:
Oxidation atmosphere resistance furnace: suitable for heat treatment carried out in an oxidizing environment.
Vacuum atmosphere resistance furnace: suitable for heat treatment in a vacuum or inert gas environment to prevent sample oxidation.
