large box furnace

The large box furnace adopts reliable integrated circuit, which has a better working environment and anti-interference. At the highest temperature, the shell temperature of the furnace body is lower than 50 degrees Celsius, which greatly improves the working environment. The large box furnace adopts microcomputer program control. The program that can be written is 2 groups of 16-section curves, fully automatic lifting temperature, and the temperature control parameters and programs can be modified during the operation of the furnace. It is very flexible and convenient, and the operation is relatively simple. Temperature control accuracy of the large box furnace is the same as the constant temperature accuracy, which is 1 degree Celsius. The heating rate of the large box furnace is very fast, and the fastest heating rate is 45/min.

The outer casing of the large box furnace is generally welded by steel and steel plates. The small electric furnace is generally made with a bracket because it needs to maintain a certain height of the working surface. Under the box type housing, there are legs supporting the furnace body or support. Large and medium-sized box furnaces (muffle furnaces) can be equipped with electric heating elements on the upper and rear walls of the furnace to reduce the temperature difference in the furnace. In order to ensure a better balance of heat loss at the furnace door, on the larger box type electric furnace, the length of the furnace 1/3 of the furnace door is used as a control area.
