In the fields of materials science, metallurgical industry, and semiconductor manufacturing, the 1200 degree program-controlled silicon carbon rod heating vacuum box atmosphere furnace has become a key equipment in laboratories and industrial production due to its performance and stable performance. Its core advantage lies in the ability to accurately control the temperature curve and complete the material's heat treatment process in a vacuum or specific atmosphere environment.

This device uses high-quality silicon carbide rods as heating elements, which have the characteristics of fast heating speed, high thermal efficiency, and long service life. Through advanced PID intelligent temperature control system, precise temperature control of ± 1 ℃ can be achieved, meeting the strict requirements of different materials for heat treatment processes. The furnace adopts a multi-layer structure design, with a stainless steel vacuum chamber on the outer layer and high-quality ceramic fiber insulation material on the inner layer, effectively reducing heat loss and improving energy utilization efficiency.

In practical applications, operators can easily set complex heating, insulation, and cooling programs through the touch screen human-machine interface.

In addition, the furnace body is also equipped with a rapid cooling system, which can significantly shorten the cooling time and improve work efficiency through a circulating water cooling device.

It is worth mentioning that the atmosphere furnace supports precise control of multiple protective gases (such as nitrogen, argon, etc.), and can adjust gas flow rate and pressure according to different process requirements. The vacuum system adopts a combination of high-performance molecular pumps and mechanical pumps, which can achieve a high vacuum environment of 10-3Pa, providing ideal conditions for the preparation of special materials.

Hengyang 1200 degree program-controlled silicon carbon rod heating vacuum box atmosphere furnaceIt is a widely used equipment in materials science research, industrial production and other fields, mainly used for processing and researching materials under high temperature, vacuum or specific atmosphere environment. Here is the relevant introduction:

characteristic

• Accurate temperature control: Using intelligent PID programming instruments for temperature control, the temperature control accuracy can reach ± 1 ℃. It can achieve 30 stage program temperature control, and can flexibly set heating, insulation, and cooling programs according to experimental or production needs to meet various complex temperature control requirements, ensuring the accuracy and repeatability of results.

• Heating performance: Using silicon carbon rods as heating elements, it has the advantages of high temperature resistance, oxidation resistance, high heating efficiency, and fast heating speed. The furnace temperature can be raised to 1200 ℃ in a short period of time, and by designing the distribution of silicon carbide rods and furnace structure reasonably, the temperature uniformity can reach within ± 5 ℃.

• Flexible atmosphere control: Multiple gases such as nitrogen, hydrogen, argon, oxygen, etc. can be introduced, equipped with a gas flow control system, which can accurately adjust the gas flow rate, create specific atmosphere environments such as oxygen free, reduction, oxidation, etc., meet the requirements of different experiments for atmosphere, and prevent samples from being oxidized or achieving specific chemical reactions at high temperatures.

• Reliable safety performance: equipped with multiple safety protection devices such as over temperature alarm, couple breaking protection, and leakage protection. When the temperature inside the furnace exceeds the set safe value or the thermocouple malfunctions, the system will automatically cut off the heating power supply to avoid equipment damage and experimental accidents.

• Good sealing design: High quality sealing materials such as silicone pads, ceramic fiber sealing ropes, etc. are used between the furnace door and the furnace body to ensure good sealing of the furnace, prevent gas leakage, and maintain the stability of the furnace atmosphere.

working principle

• Heating principle: When current passes through a silicon carbide rod, due to the resistance effect, electrical energy is converted into heat energy. After the silicon carbide rod heats up, the heat is transferred to the inside of the furnace through heat conduction, heat radiation, and heat convection, causing the temperature inside the furnace to rise.

• Temperature control principle: The temperature sensor monitors the temperature inside the furnace in real time and converts the temperature signal into an electrical signal to transmit to the controller. The controller calculates the required heating power through PID control algorithm based on the difference between the preset heating program and the actual temperature, and then adjusts the power on state of the silicon carbide rod to achieve precise control of the furnace temperature.

• Principle of Vacuum and Atmosphere Control: The vacuum system uses mechanical pumps, molecular pumps, diffusion pumps, etc. to pump the furnace to the required vacuum degree, in order to prevent materials from undergoing oxidation, nitriding, and other reactions at high temperatures. When introducing atmospheric gas, the flow rate and pressure of the gas are precisely controlled by a mass flow meter to create a stable and uniform atmosphere environment.

With the continuous deepening of new material research and development, the 1200 degree program-controlled silicon carbon rod heating vacuum box atmosphere furnace will demonstrate its value in more fields. In the future, by further optimizing control systems and improving energy efficiency, such equipment is expected to provide more efficient heat treatment solutions for advanced material preparation.
