box-type resistance furnace

1、box-type resistance furnacepurpose:

this seriesbox-type resistance furnaceMainly used for the analysis and determination of various elements in various laboratories, industrial and mining enterprises, and scientific research institutions, it can also be used for annealing, quenching, tempering and other heat treatment heating of general small steel parts

2、Equipment technical parameters:

3、Equipment composition:

The SC/XSL-30-9 box type resistance furnace is mainly composed of furnace shell, furnace lining, heating element, furnace door, temperature measuring element, control device, etc.

4、Equipment Introduction:

4.1Furnace shell:Mainly welded from steel plates and sections, it has sufficient strength and rigidity to effectively ensure the temperature of the shell

Low and aesthetically pleasing in appearance.

4.2Furnace lining:The furnace material is compressed and formed using Isolite ceramic fiber modules The bottom insulation layer is made of lightweight insulation bricks, which have good insulation performance, can resist rapid heating and cooling, do not consider the influence of thermal stress, are energy-saving, have high strength, and do not deform.

4.3Heating element:High quality high-temperature resistance tape (0Cr27Al7Mo2) is wound into a wavy shape and arranged inside the furnace. The resistance tape is designed with low surface load and has a long service life.

4.4fire door:The high-temperature box furnace door adopts a manual opening structure, consisting of a chain, sprocket, and transmission shaft, and its structure is safe and reliable.

4.5Electrical control part:The electrical control system integrates temperature control and electrical control into a comprehensive control system, which can reflect the current electronic control technology in a centralized manner. The main circuit adopts a thyristor module, and the temperature control instrument adopts the Shanghai Guolong TCW-32B PID intelligent temperature controller. The PV/SV digital display is displayed simultaneously, and the instrument can be manually adjusted. The PID expert control system usually adjusts automatically, and the temperature control realizes PID parameter self-tuning. The electrical cabinet is a GGD standard cabinet type, and brand products are used for air switches, relays, and contactors.
