Double layered furnace structure with air cooling system

High purity alumina fiber is used as furnace material, and the surface is coated with alumina coating

Using a DC motor to drive the furnace tube to rotate, with a speed of 0-10 RPM

The furnace body can be tilted, with a maximum tilt angle of 30 °

The open design of the furnace body can achieve rapid cooling and facilitate the replacement of furnace tubes

The furnace body is equipped with an automatic feeder with a sealed structure, which can feed the powder into the furnace tube under inert gas protection environment

The feeding rate can be adjusted through a potentiometer, and the maximum feeding rate is 97cm ^ 3/min

A stainless steel receiving tank (with a capacity of 1L) installed at the discharge end, capable of collecting and processing materials in an atmosphere protected environment

● Two heating zones, each with a length of 200mm, for a total heating zone length of 400mm

Length of constant temperature zone: 200 mm (+/-1 ℃, with the same temperature set for both zones)

Quartz furnace tube size: 100 mm O.Dx 1200 mm L (special-shaped pipe)

● Diameter of 60mm at both ends)

The furnace tube is welded with a sheet metal, which can better mix the materials

The instrument includes a pair of stainless steel sealing flanges (with stainless steel needle valves and rotary joints installed on the flanges)

Maximum operating temperature: 1200 ℃ (<1 hour)

Continuous operating temperature: 1100 ℃

Two temperature zones have two independent temperature control systems, both of which can be set with 30 temperature rise and fall programs

● Adopting Omega K-type thermocouple

● Rotary furnace: 4KW

● Feeder: 200W

● Furnace body: 1300mm × 600mm × 1200mm

● Feeder: 220mm × 220mm × 202mm

● Can cooperate with our company's gas supply system to use CVD method for coating and surface modification of powder materials

● Optional large capacity automatic feeder

●The pressure inside the furnace tube cannot exceed 0.02MPa

●Due to the high internal pressure of the gas cylinder, a pressure reducing valve must be installed on the cylinder when introducing gas into the furnace tube. It is recommended to purchase a pressure reducing valve from our company, which has a range of 0.01MPa-0.1MPa and can be used more accurately and safely

●When the temperature of the furnace body is higher than 1000 ℃, the furnace tube cannot be in a vacuum state. The pressure inside the furnace tube should be equivalent to atmospheric pressure and maintained at atmospheric pressure

●The gas flow rate entering the furnace tube should be less than 200SCCM to avoid the impact of cold large airflow on the heated quartz tube

●The long-term use temperature of quartz tube is less than 1100 ℃

●For the experiment of sample heating, it is not recommended to close the exhaust valve and inlet valve at the flange end of the furnace tube. If it is necessary to close the gas valve to heat the sample, it is necessary to constantly pay attention to the reading on the pressure gauge. If the pressure reading is greater than 0.02 MPa, the vent valve must be opened immediately to prevent accidents (such as furnace tube rupture, flange flying out, etc.)
