High temperature vacuum atmosphere furnace

The main purpose

Vacuum atmosphere furnace (with gas detection device) is widely used in universities, scientific research institutes, industrial and mining enterprises for high temperature sintering, metal annealing, chemical industry, metallurgy, ceramics, new material development, organic matter ashing, and quality testing. It is also suitable Used in the production and experimentation of military industry, electronics, medicine, special materials, etc.

Product Introduction

The high temperature atmosphere furnace series is a horizontal vacuum atmosphere box furnace, which can also be called an oxygen-free annealing furnace or a vacuum atmosphere sintering furnace. It is specially designed to process materials in a vacuum state and an atmosphere (such as inert gas, etc.) Sintering, the high temperature can reach 1800 ℃, the introduction of foreign technology, independent research and development and production, energy-saving, new electric furnace. It has a reasonable double-layer shell structure, the surface temperature is less than or equal to 40 ℃ , and the appearance is beautiful and generous. It is processed by cold-rolled steel plate, CNC machine tools, high-precision laser cutting machines, and CNC bending machines. The surface is beautiful, luxurious, and two-color. The oxidized powder is electrostatically sprayed to achieve a durable, non-fading, high-temperature and corrosion-resistant surface treatment.

Heating element: Choose different heating elements according to the furnace temperature. Heating elements are divided into: electric furnace wire, resistance band, silicon carbide rod, silicon molybdenum rod, and molybdenum wire.

Liner material: The liner is made of imported temperature refractory materials and constructed by the craftsmanship. Strong thermal shock resistance, good corrosion resistance, no collapse, no crystallization, no slag, and long service life!

Temperature control mode: microcomputer intelligent adjustment technology, PID adjustment, automatic control, self-tuning function; multi-segment program programming, and can control various heating, heat preservation, and cooling programs; power adjustment; high temperature control accuracy; integrated module thyristor control , Phase shift trigger. Protection device: independent over-temperature protection, over-voltage, over-current, leakage, short-circuit protection, etc., with a high degree of automation, and all indicators have reached the level.

Features
