How about a high-temperature heat treatment furnace?

High temperature heat treatment furnace is an important industrial equipment, and the following is a detailed introduction to it:

1. Main functions and features
Energy saving: High temperature heat treatment furnaces usually use high-purity composite alumina/ceramic polycrystalline fibers as furnace materials, which are lightweight and have less heat storage, thus achieving energy-saving effects. At the same time, its heating elements (such as resistance wires, silicon carbon rods, silicon molybdenum rods) have a long service life, are easy to replace, and further reduce energy consumption.
Integrated design: The high-temperature heat treatment furnace adopts an integrated design, making it more flexible to use and less prone to breakage, saving operating space.
High precision temperature control: The temperature control accuracy of high-temperature heat treatment furnaces can usually reach ± 1 ℃, and are equipped with a microcomputer program temperature control system. The heating rate can be adjusted, and automatic operation does not require manual supervision.
Multiple protection: The equipment has automatic protection alarm functions such as over temperature, over pressure, over current, leakage, broken couple, and broken rod, ensuring safe use.
Widely applicable: High temperature heat treatment furnaces are widely used in universities, research institutes, industrial and mining enterprises, and other fields, suitable for experiments and production of powders, electronics, metallurgy, medicine, ceramics, sulfur, glass new materials, chemical engineering, metal sintering, and metal heat treatment.

2. Heating element and its advantages and disadvantages
The heating elements of high-temperature heat treatment furnaces mainly include resistance wires, silicon carbon rods, and silicon molybdenum rods.
Resistance wire: Resistance wire is inexpensive, easy to control, and easy to install. But its heating uniformity is poor, which may lead to certain temperature differences in the furnace.
Silicon carbon rod: Silicon carbon rod has a moderate cost, high cost-effectiveness, and easy replacement. However, its seismic resistance is poor and it is sensitive to temperature changes. During long-term high-temperature use, it will gradually age and its resistance value will change, resulting in a decrease in heating power and requiring regular replacement.
Silicon molybdenum rod: Silicon molybdenum rod has excellent high temperature resistance, fast heating rate, strong oxidation resistance, and good heating uniformity. But the higher price increases the cost of high-temperature heat treatment furnaces. At the same time, the texture is brittle in high temperature environments and is prone to breakage when subjected to external impact or rapid temperature changes. Special care is required during installation, use, and maintenance.

3. Main technical parameters
The main technical parameters of high-temperature heat treatment furnaces include rated voltage, design temperature, heating rate, heating elements, temperature control accuracy, etc. Among them, the design temperature is usually between 800 ℃ and 1800 ℃, the heating rate can be adjusted, and the temperature control accuracy can reach ± 1 ℃.

4. Service life
The service life of high-temperature heat treatment furnaces is generally 5 to 15 years, depending on equipment quality, usage environment, and maintenance. High quality heat treatment furnaces use high-quality materials and advanced manufacturing processes, with stable structures and good corrosion resistance, resulting in a relatively long service life. Meanwhile, proper maintenance and upkeep can also extend the service life of equipment.

5. Application examples
High temperature heat treatment furnaces are widely used in various fields. For example, in the metallurgical industry, it can be used to prepare metal alloys; In the glass industry, it can be used to prepare ceramic materials and glass products; In the pharmaceutical industry, it can be used for drug testing and pre-treatment of medical samples. In addition, it can also be used to test the properties and behavior of materials under high temperature conditions, such as measuring parameters such as thermal expansion coefficient, thermal conductivity, and electrical conductivity of materials at high temperatures.

In summary, high-temperature heat treatment furnaces are powerful and widely used equipment. When selecting and using, it is necessary to choose suitable models and specifications based on specific application scenarios and requirements, and pay attention to equipment maintenance to extend its service life.
