Description

technical field [0001] The invention relates to the technical field of electric furnace processing and manufacturing, in particular to a box-type electric furnace. Background technique [0002] Electric furnace is a general heating equipment, which can be divided into box furnace, tube furnace and crucible furnace according to the appearance and shape. Electric furnaces are mainly used in thermal processing, industrial workpiece processing, cement, and building materials industries, for thermal processing or treatment of small workpieces; for drug testing, pretreatment of medical samples, etc.; as sample processing in water quality analysis, environmental analysis, etc. ; It can also be used for petroleum and its analysis; for the determination of moisture, ash, volatile matter, ash melting point analysis, ash composition analysis, elemental analysis; it can also be used as a general ashing furnace. Among them, the box-type resistance furnace is an industrial furnace that u...

AI Technical Summary

Problems solved by technology

At present, the traditional box-type electric furnace has high energy consumption, high pollution, and high cost of use, which cannot meet the requirements of modern use.

Moreover, its heating element has poor heat resistance and cannot meet the requirements for use

In addition, its temperature control accuracy is low, and manual real-time monitoring is also required, which cannot meet the requirements of modern use.
