1200°C Electric Muffle Furnaces（STM-30-12）

Description

1200℃ muffle furnace (box-type resistance furnace) is used in the sintering and heating of new materials such as metal materials, ceramic materials, nano-materials, semiconductor materials, etc. High temperature heat treatment.

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. Strong metal frame shell structure, low furnace surface temperature.
3. Side-opening furnace door structure, the furnace door opens to the right, 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. High-quality HRE spiral resistance wire heating element is safely and firmly embedded on the surface 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 three sides (left and right sides and furnace bottom), so as to achieve good uniformity in the furnace.
3. The silicon carbide bottom plate covers and protects the bottom heating element, which has high mechanical strength, good thermal conductivity, and provides horizontal load bearing.

Temperature Control Panel

1. PID and SSR control mode, precise temperature control.
2. Internationally standardized N-type nickel-chromium-silicon thermocouple with a temperature measurement range of 0-1300℃ and a long service life.
3. The furnace door is equipped with a door-opening power-off safety protection switch.

Program Controller

1. Advanced controllers that meet complex process requirements
2. Simple and direct operation, flexible programming
3. Programmable 30 program segments for a single curve
4. Over temperature and fault alarm, automatic safety protection
