Technical parameters
Instrument	Taiwan Hongji Jia
Heating rate	Adjustable from 5 to 25/min
Temperature zone distribution	The left and right are divided into dual temperature zones for temperature control, making the temperature control more precise
The bottom of the furnace is loaded	20kg
Control mode	Control mode: It adopts an intelligent temperature control instrument + fully automatic control system. After setting the program from room temperature to the set temperature, it can run automatically. The system is controlled by a thyristor. The temperature control system is modularly designed, with a simple structure and convenient maintenance. It adopts Yudian instrument, with thyristor control, 30-segment programmable function, multi-segment power limit function, multi-group PID parameter self-tuning function, freely settable constant temperature and heat preservation curves, interference-free switching function, and the instrument has temperature correction and compensation functions. Functions such as real-time tracking, historical records, and output reports; Over-temperature alarm and power-off, leakage protection
Digital display	Dual display for temperature measurement and setting, as well as heating power light column display
Control characteristics	The control system features a modular structure, with long-life design for key components of the equipment. The process is simple, reliable, stable and highly precise.
Refractory materials	The furnace lining is made of high-purity alumina fiber, vacuum-formed fiber lightweight board material, and lightweight hollow sphere alumina plate. It features high operating temperature, low heat storage capacity, resistance to sudden heating and cooling, no cracking, no chipping, and excellent heat preservation performance (energy-saving effect is over 80% of that of the old-fashioned electric furnace). The patent of the double-furnace chamber structure not only features a fast heating rate but also is sturdy and durable, with the patented characteristics of not collapsing even after long-term use. The bottom of the furnace is made of high-density mullite refractory bricks, which are load-bearing and wear-resistant.
Thermal insulation material	Alumina multi-fiber insulation material, with an insulation layer of 360mm.
Shell	The furnace body and shell are welded with steel plates and profiles. The outer shell is also equipped with detachable protective plates, which are electrostatically sprayed and baked with paint. Fine workmanship and elegant appearance.
Furnace insulation
Furnace chamber structure	Double-layer furnace shell structure, air-cooled circulation, to reduce the shell temperature. The surface temperature of the shell is less than 40℃. The inner furnace chamber surface is coated with high-temperature alumina coating, which can improve the heating efficiency of the equipment and also extend the service life of the instrument. The opening between the furnace door and the furnace body is connected by hinges. The sealing between the furnace door and the furnace body is tightened with high-temperature resistant alumina cotton and stainless steel lock rings. The furnace legs are in an eight-shaped structure. Between the two legs, there are connecting plates and reinforcing plates welded at the bottom steps on both sides to facilitate the horizontal movement of the equipment during installation. The equipment openings are divided into: 3 holes for heating electrodes and 1
Bottom loading area	The rear and the edges of both sides are raised by 150mm to prevent the heating wire from being hit when taking or placing materials
Structural characteristics	The furnace body heats up on all four sides, with heating elements, thermocouples and controllers. Some of the furnace chamber materials are composed of ceramic fiber materials and hollow sphere alumina. The upper part of the furnace chamber is a mesh furnace cover, and the carbon steel plate on the side of the furnace body is 3mm. To prevent heat loss in the form of thermal radiation, double furnace door seals are adopted.
Electronic control system
Energy-saving performance	It is lightweight, heats up quickly, saves more than 50% of energy, and is time-saving and labor-saving.
Random spare parts	One instruction manual, one certificate of conformity, one insulating brick for the furnace door, one pair of tongs, one pair of high-temperature gloves

It is widely applied in departments such as soil, geology, mineral resources, metallurgy, electronics, building materials, ceramics, chemical engineering, light industry, medicine, and environmental protection.
