Analysis of the temperature range and temperature control accuracy of industrial ovens

In industrial production, the temperature range of the oven and the precision of temperature control directly affects the heating and drying effect, and different industries have different temperature requirements. Jiangsu Ruiyuan Heating Equipment Technology Co., Ltd. provides a diverse range of industrial oven models to meet all kinds of needs from low-temperature drying to high-temperature heat treatment.

1. Temperature range of industrial ovens

The temperature range of industrial ovens usually varies depending on the heating method and application requirements. The following are some common temperature ranges:

1.1 Low-temperature oven (room temperature to 150°C)
Cryogenic ovens are suitable for processes with low temperature requirements, such as sample drying, low temperature drying and the food industry. Low temperature ovens are often used for the removal of moisture and volatiles, have low energy consumption and are simple to operate.

1.2 Medium temperature oven (150°C to 300°C)
Medium temperature ovens are the standard choice for many industrial applications and are particularly suitable for drying, heat curing or heat treating in the chemical, electronics and rubber industries. This temperature range ensures that materials are not excessively damaged, but also meets some of the needs for efficient drying.

1.3 High-temperature ovens (above 300°C)
High temperature ovens are used for heat treatment processes with high temperature requirements and are suitable for operations such as materials testing and powder coating curing. Some high temperature ovens can reach temperatures of 500°C or even higher for more demanding industrial applications.

2. Temperature control accuracy

Temperature control accuracy is one of the important indicators of oven performance, directly related to the stability of the heating process and the consistency of the finished product. Precise temperature control can effectively avoid the quality problems brought about by excessive temperature difference. Usually, the temperature control accuracy of industrial oven can be divided into the following categories:

2.1 Accuracy within ±2°C
These ovens are suitable for processes requiring high temperature control, such as drying of electronic components and laboratory testing. Through the precise temperature control system, these ovens can maintain a uniform and stable temperature environment.

2.2 Accuracy within ±5°C
Medium-precision ovens are suitable for some industries that require less strict precision in temperature control. Drying and heat treatment in electronic manufacturing, light industry and some chemical industries usually use such ovens.

2.3 Accuracy of about ±10°C
Lower precision ovens are suitable for processes that are tolerant of temperature differences, such as high volume drying or rough heat treatment. These ovens are capable of meeting basic heating requirements while being low cost and energy efficient.

3. Temperature control systems and technologies

Jiangsu Ruiyuan Heating Equipment Technology Co., Ltd.'s oven is equipped with efficient temperature control system, which can meet a variety of temperature control accuracy requirements. The following are commonly used temperature control techniques:

3.1 PID control
PID (Proportional-Integral-Derivative) control system can be adjusted according to the deviation between the temperature setting value and the actual temperature, so as to realise the precise temperature control effect.PID control is widely used in ovens which require high precision of temperature control.

3.2 Multi-point temperature monitoring
In order to reduce the phenomenon of uneven temperature distribution, many high-end ovens will use multi-point temperature monitoring, through multiple temperature sensors to detect the temperature of each point in the oven in real time. This approach not only improves the accuracy of temperature control, but also ensures the consistency of the product during the heating process.

3.3 Intelligent temperature management system
Some ovens are equipped with an intelligent temperature control system that can automatically detect and adjust the heating method to maintain the optimal temperature. The intelligent system dynamically adjusts the temperature by analysing temperature data to reduce human error.
