  • About Liyu Furnace


Equipment widely used in universities, research institutes, industrial and mining enterprises such as powder, military, electronics, metallurgy, medicine, ceramics, glass, machinery, new material development, special materials, refractory materials, building materials, chemicals, metal sintering and metal heat treatment Experiment and production.

Technical Characteristics

This equipment has introduced advanced technology, independent research and development of energy-saving, environmentally friendly new electric furnace, the device has a scientific and rational design technology, elegant appearance, advanced and reasonable structure, easy operation, high-quality cold-rolled steel shell, the precision CNC machining, Luxury, beautiful two-color imported epoxy powder electrostatic spray process from processing, high temperature, corrosion-resistant, long-term from fade.

The furnace has a uniform temperature field, the surface temperature of the double-layer heat-resistant furnace body is close to room temperature, and the heating and cooling functions are adjustable. The furnace adopts imported high-temperature composite fiber materials and is constructed by a numerical control process. Chilling heat, corrosion resistance, non-collapse, no crystallization, no residue, no pollution, long service life.

The control system uses microcomputer intelligent adjustment technology, with PID adjustment, automatic control, self-tuning function, 50 sections of programming, and the preparation of a variety of heating, thermostat, cooling program, temperature control accuracy.

Protection device using independent protection: (over-temperature, over-voltage, super-current, broken even, power, leakage, short circuit, etc.).

In addition, through our independent research and development of control software, electric furnace and computer associated single or multiple furnace can be achieved remote control, start the electric furnace, stop the electric furnace, set the temperature program, temperature program storage, view the history curve, print Historical curve and so on.

Honors: ISO9001: 2008, CE ,AAA certificate

Production Process


Automatic cutting

This is a CNC machine tool .Set it to the right shape according to the drawing. Very high accuracy which can be just 0.02mm deviation at most.


Edge Folding Machine

Micro computer control.Set the data sheet according to the drawing.then put the steel plate into a 90°angle.With all of this parts ,it made of the frame of the furnace.



Welding the different part of the furnace together.Polishing it very smooth.



Epoxy coated which make the surface very good and it keep the clour for a very long time.


Install and debugging

Install the heating element,chamber,wire all together into the furnace.Also adjustment the Program to english or chinese as customer need.



Liyu furnace make different kind of furnace from small size to very big one.Temperature from 800-2200 degree(The average of the line is 1700 degree).



Put the wooden stick into the chamber,then plastic bags,bubble,Wooden case outside and then wrapping film.



We have our own car to send the furnace to port which can guarantee it safe before get to the port.
