1700°C Single Zone Tube Furnaces

Features

Furnace shell

1. The shell is made of metal Q235 low-carbon steel, and the surface is electrostatically resistant and resistant to corrosion.
2. The solid double-layer metal frame is combined with the heat-insulating fan structure, and the furnace surface temperature is low
3. Horizontal use mode, easy to operate

Refractory material

Multi-layer insulation design, composed of lightweight alumina ceramic fiber and high-quality insulation board backing, does not contain asbestos components, low heat loss and low energy consumption

Heating system

1. The high-quality Mosi2 heating element is safely and firmly installed on both sides of the furnace, and is heated by free heat radiation in the furnace cavity, which is energy-saving and efficient, and has a long service life
2. Heating on both sides (left and right sides), so as to achieve good uniformity in the furnace

Temperature Control Panel

1. PID and SSR control mode, precise temperature control
2. International standardized B-type Ni - Cr silicon thermocouple, temperature range 0-1800°C, long service life
3. Equipped with heating indicator light and over-temperature alarm buzzer

Program Controller

1. Advanced controllers that meet complex process requirements
2. Simple and direct operation, flexible programming
3. Programmable 32 program segments
4. Over temperature and fault alarm, automatic safety protection

Vacuum Atmosphere Function

1.With 304 stainless steel sealing flange to obtain vacuum or atmosphere in the furnace tube

1. High-quality quartz glass working tube, and metal or corundum working tube can also be selected to adapt to different working conditions
