Vacuum tube furnace

The vacuum sealing system adopts special design technology, with safe and convenient operation, high vacuum degree, good sealing performance and long vacuum holding time. The sealing adopts stainless steel metal flange and O-type high temperature resistant fluororubber ring.

The gas enters the furnace tube through the needle valve switch after passing through the flowmeter. The valve control is equipped with inlet valve, exhaust valve and vacuum pumping valve. The pressure reducing valve and safety valve can pass a variety of gases, such as argon, nitrogen, oxygen, carbon monoxide and ammonia decomposition gas, and can be filled with high-pressure gas. The unique sealing technology can maintain the pressure for a long time, with good safety performance and convenient operation.

Heating system:

high-quality heating elements are used.

According to different temperatures required by customers, highquality resistance wires, silicon carbide rods, silicon molybdenum rods, etc.

are used. The furnace has the advantages of balanced temperature field, low furnace surface temperature, fast temperature rise and fall rate and energy saving. Furnace and cooling system: the furnace is made of alumina ceramic fiber through a unique process, with strong thermal shock resistance, good corrosion resistance, no collapse, no crystallization, no slag falling, no pollution, long service life, good thermal insulation performance, and only 40% power is required for thermal insulation. High purity quartz tube or corundum tube is used as the inner furnace. Detachable three side sealing mode, with good cleanliness and vacuum.

Temperature control system: the control system adopts microcomputer full-automatic intelligent

regulation technology, with PID regulation, fuzzy control, self-tuning functions, multi stage

programming,   and can prepare various heating, insulation and cooling procedures with high

temperature control accuracy; The integrated module is controlled by thyristor and triggered by phase shifting, and the temperature control accuracy can reach ± 1 ℃.

Display mode: LED digital display instrument, optional luxury intelligent touch screen instrument, real-time curve display, U disk can also be used to export data, and viewing software can be installed

on the computer.

Protection system: it adopts independent over temperature protection, over voltage, over current, leakage, short circuit and other protection, with a high degree of automation. All indicators have reached the most advanced international level.

The rotary tubular furnace can be customized according to the process requirements of customers

Rotary tubular furnace is mainly used for laboratory calcination and drying of positive and negative electrode materials such as lithium-ion batteries, no strong acid-base powder materials, and granular materials. Users can burn them under vacuum or atmosphere protection according to the choice of materials to be burned.

Main features of rotary tube furnace: the control system of the equipment is internationally leading, with the characteristics of safety and reliability, simple operation, high temperature control accuracy (Expert PID control), good insulation effect, large temperature range, high furnace temperature uniformity, many temperature zones, atmosphere vacuumization, tilt angle, 360 ℃ rotation of furnace tube, etc
