1700℃ Controlled Atmosphere Furnace Nitrogen Inert Atmosphere Furnace

Introduction

The KT-17A Controlled Atmosphere Furnace is a versatile furnace designed for both laboratory and industrial applications. It features a heavy-duty vacuum chamber structure and scientific united control panel for vacuum suction and inert gas pressure and flow. The double furnace shell design with forced air flow cooling controls the furnace surface temperature, while the PID programmable temperature control ensures excellent control accuracy. The furnace is equipped with a ceramic polycrystalline fiber insulation liner for less heat loss and superior energy-saving efficiency. Professional heating elements optimize heat radiation properties and ensure a long service life. The safety interlock system automatically shuts off power when the furnace door is open, the temperature is too high, or a sensor is broken. The KT-17A Pro model features a 7-inch TFT smart touch screen controller for friendly program setting and history data analysis.

Applications

The Controlled Atmosphere Furnace is a versatile and efficient tool designed for various high-temperature processes requiring precise atmosphere control. This furnace, equipped with advanced features such as temperature controller and a polycrystalline alumina fibre chamber, is ideal for applications in industrial settings, scientific research institutes, and universities. Its ability to pre-vacuum and handle gases like H2, Ar, N2, O2, CO, and NH3 makes it suitable for a range of specialized processes.

• Atmosphere Protection Sintering: Ideal for sintering materials under controlled atmospheres to prevent oxidation and enhance material properties.
• Atmosphere Reducing Processes: Used in processes that require a reduction in the presence of oxygen, such as in the production of certain alloys or ceramics.
• Material Research and Development: Essential for researchers studying the effects of controlled atmospheres on material properties and behaviors.
• Small Batch Production: Particularly useful in the production of semiconductors, silicon nitride, and other sensitive materials where atmosphere control is critical.
• Educational Purposes: Provides hands-on experience for students in materials science and engineering, demonstrating the practical aspects of controlled atmosphere furnaces.

Principle

KT-17A Controlled Atmosphere Furnace employs an airtight vacuum-sealed heating chamber. The insulation chamber and heating element reside within a robust vacuum chamber, akin to a vacuum glove box. An operator utilizes a vacuum pump to evacuate the chamber to a negative pressure of -0.1Mpa. Subsequently, inert gas is introduced to establish a controlled atmosphere environment. The furnace incorporates vacuum pressure gauges, vacuum suction ports with valves, gas purging ports with valves, and float flowmeters, making it suitable for both laboratory and industrial applications.

Warnings

Operator safety is the top important issue! Please operate the equipment with cautions. Working with inflammable& explosive or toxic gases is very dangerous, operators must take all necessary precautions before starting the equipment. Working with positive pressure inside the reactors or chambers is dangerous, operator must fellow the safety procedures strictly. Extra caution must also be taken when operating with air-reactive materials, especially under vacuum. A leak can draw air into the apparatus and cause a violent reaction to occur.
