2000℃ temperature controlled induction heating furnace 30KW

    It is a large-scale high-temperature induction heating and melting furnace system, equipped with 30KW induction heater, 8.5 ″ (216mm) quartz tube, hinged flange and valve, graphite Crucible, graphite blanket, alumina insulation blanket, 16L / min circulating chiller, vacuum pump and mobile furnace cart.

CY-85KTC is a large-scale high-temperature induction heating and melting furnace system, equipped with 30KW induction heater, 8.5″ (216mm) quartz tube, hinged flange and valve, graphite Crucible, graphite blanket, alumina insulation blanket, 16L / min circulating chiller, vacuum pump and mobile furnace cart, the highest temperature can reach 2000℃ (protective gas needs to be introduced into the quartz tube during use), which is a better choice for growing crystal, melting metal and heat treatment of various materials.

Technical parameters of induction heating furnace:

Product model

2000 temperature controlled 30KW induction heating furnace CY-85KTC

Main features

 1. A refractory made of multiple pieces of alumina is used to support the graphite crucible and prevent heat radiation.

2. Equipped with automatic water pressure, overheating, and high power protection system.

3. The temperature controller adopts PID to control the temperature, and can set up 30 sections of temperature rise and fall programs, and has overheating and broken couple protection functions.

4. Equipped with anti-corrosion vacuum gauge, when the air pressure is above 10mbar, there is no need to convert the coefficient according to the type of measured gas, and the range can reach 3.8 × 10E-5Torr.

5. Mini-float flowmeter accuracy is 4%.

6. Equipped with two-stage rotary vane mechanical pump (2L / s), which can make the vacuum degree in the quartz tube reach 10E-2torr.

Mobile cart

Size: 700mm × 1000mm × 700mm, steel frame structure, easy to move induction heater and quartz tube with flange

Matters needing attention

Before operation, the instructions must be read carefully, and   the operator must wear a protective mask. When used, the smelting must be carried out under flowing argon ≤0.02Mpa,

When the flow rate is less than 200ml / min, the air pressure in  the quartz tube must always be kept <0.02MPa. During the heating process, always pay attention to the air pressure in the quartz tube. If the air pressure exceeds the safe value, it will cause the quartz tube to crack, the flange pops out, and even physical injury.

Other matters

This machine can be changed to RTP (rapid heat treatment furnace) and mixture physical chemical vapor deposition (HPCVD) system.
