The box type resistance furnace plays a crucial role in the sintering process, mainly reflected in the following aspects:
1. Provide high temperature environment
The box type resistance furnace converts the electrical energy of the resistance wire into thermal energy, raising the temperature inside the furnace to the level required for sintering. This high-temperature environment is the basis for the sintering process, allowing powdered iron containing raw materials (or other materials that need to be sintered) to undergo a series of physical and chemical reactions at high temperatures, thereby achieving sintering.
2. Control sintering temperature
The box type resistance furnace is equipped with an advanced temperature control system, usually using a microcomputer chip processor, with functions such as PID adjustment, time setting, automatic temperature difference correction, and over temperature alarm. This enables precise control of the furnace temperature within the required range, ensuring the stability and controllability of the sintering process.
3. Ensure sintering quality
The furnace chamber of the box type resistance furnace is made of high-temperature refractory materials, with a long service life, high sealing, low heat loss, and high temperature uniformity. These characteristics ensure the uniformity and stability of the temperature inside the furnace during the sintering process, thereby improving the quality of the sintered ore.
4. Improve sintering efficiency
Box type resistance furnaces have advantages such as fast heating and energy saving. The heating rate can be adjusted as needed, and the furnace has good insulation performance, reducing energy waste. This enables the sintering process to proceed faster and improves production efficiency.
5. Wide applicability
Box type resistance furnaces are not only suitable for sintering processes in the steel industry, but also widely used in the production and experimentation of ceramics, metallurgy, electronics, glass, chemical industry, machinery, refractory materials, new material development, special materials, building materials and other fields. This demonstrates its wide applicability and importance in the sintering process.
In summary, the box type resistance furnace provides the necessary high-temperature environment, precise temperature control, good sintering quality, efficient sintering efficiency, and a wide range of applications during the sintering process. Therefore, it is an indispensable and important equipment in the sintering process.
