Introduction of the Industrial Muffle Furnace:

The KSL-1700X-S is a high-temperature small box furnace. It uses silicon-molybdenum rods as heating elements. The small box furnace features a double-shell structure, PID programmable temperature control, and a B-type thermocouple. The furnace chamber is constructed of high-purity alumina fiber. Its maximum temperature can reach 1700°C, with a continuous operating temperature of 1600°C and a temperature control accuracy of ±1°C. The small box furnace offers advantages such as uniform temperature distribution, low surface temperature, and energy efficiency. It is ideal for high-temperature sintering, metal annealing, and quality inspection in universities, research institutes, and industrial and mining enterprises.

The relationship between power consumption and power consumption of a high-temperature mini box furnace:

When using mini box furnaces of the same size but different power ratings to heat to 1,000°C, the heat required to heat a high-power mini box furnace to 1,000°C is the same as that required to heat a low-power Small box furnace to the same temperature. The only difference is that the high-power small-box furnace performs more work per unit time and heats faster. This is because the small-box furnace can generate more heat in a shorter period of time, reaching the required temperature faster. On the other hand, the low-power muffle furnace performs less work per unit time and generates less heat in the same period of time, so it naturally takes longer to reach the required temperature.


Methods for Reducing Mini box furnace Power Consumption:

The power consumption of a muffle furnace is affected by factors such as the size of the furnace chamber, the insulation material and thickness, and the material and size of the heating material. Therefore, to reduce the power consumption of a muffle furnace, you can consider the following aspects:


1. Choose a reasonable furnace chamber size.

2. Select appropriate insulation materials.

3. Ensure the material and size of the heating material are appropriate.


The difference between a tube furnace and a Industrial muffle furnace: 

1. Different production volume: Since the diameter of a tube furnace is fixed, its production volume is relatively small; while the size of the muffle furnace can be adjusted, the test or production volume is larger. 2. Different calcination atmosphere: When using a tube furnace for calcination, the workpiece cannot be fully integrated with the air, which easily leads to incomplete calcination; while in a muffle furnace, the workpiece can be fully integrated with the air during the calcination process, so that it can be fully calcined. 


What are the factors that affect the temperature error of a Small box furnace? 

1. Error caused by the thermocouple: 

(1) Thermocouple unevenness. 

(2) Thermocouple instability. 


2. Display error: 

(1) The influence of cold end temperature 

(2) The influence of nonlinearity. 

(3) The influence of signal processing.
