1400 ℃ High Temperature Vacuum Atmosphere Furnace

1400 ℃ vacuum atmosphere furnace is also called anaerobic annealing furnace, vacuum atmosphere sintering furnace, etc. This method uses a certain gas to sinter objects in the furnace of an open vacuum atmosphere tube furnace.

1. Product Parameter

Common temperature: 1400℃

Temperature control accuracy: ±1℃

Furnace temperature uniformity: ±3℃

Temperature measurement range: 0-1700℃

Adjustment range:  The fastest heating rate is 40 degrees per minute (40°C/min), and the slowest heating rate is 1 degree per hour (1°C/h).

Vacuum atmosphere furnace atmosphere control:  the air inlet of the electric furnace is on the top of the furnace, and the air outlet is on the bottom of the furnace; various gases (oxygen, nitrogen, argon, hydrogen, carbon monoxide, etc.) and vacuum can be added; there is an air inlet outside the electric furnace. The pressure reducing valve has the function of preheating the intake air, and the gas flow rate adopts a rotameter. If the customer needs, it can also install a digital mass flow meter to accurately control the intake air volume.

Vacuum degree of vacuum atmosphere furnace:  vacuum gauge indicates -0.1MPa, positive pressure 0.3MPa

Safety:  The electric furnace is equipped with an electric contact pressure switch to prevent the electric furnace from excessively high positive pressure and high temperature power failure. Electric furnace with explosion-proof valve!

Vacuum atmosphere furnace cooling structure:  double shell, air cooling + water cooling, equipped with circulating water pump and circulating water tank (300L), furnace door, furnace mouth and furnace roof three-layer cooling part.

1400 ℃ Carbon Fiber Continuous Carbonization Furnace

1. Application

A 1400 ℃ continuous carbonization furnace suitable for polyacrylonitrile-based carbon fiber, pitch-based carbon fiber, viscose-based carbon fiber, phenol-based carbon fiber, vapor-phase grown carbon fiber, and various carbon papers.

2. Features

(1)  The carbonization furnace adopts independent temperature control in the temperature zone, forming a system with a constant temperature gradient.

(2)  The carbonization furnace adopts a unique gas circuit sealing system to make the oxygen pickup in the furnace meet the working requirements.

(3)  The exhaust gas discharge adopts pressure difference design.

(4)  A water cooling device is installed at the outlet end to cool the fiber to below 300°C and enter the external space to prevent oxidation.

(5)  The temperature control adopts the imported single-loop control only by the temperature controller, and the temperature control accuracy is high and the temperature stability is high. It has the sound and light alarm system for over temperature, broken couple, low air pressure, low water pressure, and water temperature over temperature.
