1200℃ high temperature ceramic fiber muffle furnace for laboratory use

"So the critical phase transition mentioned in the literature really exists..." She was rapidly recording the data fluctuation patterns when the cuff of her lab coat accidentally brushed against the control panel, triggering the holographic projection device. In an instant, the entire laboratory was filled with a three-dimensional thermodynamic model, with countless fluorescent wireframes interweaving in the air to create a stunning energy distribution map.

The 1200℃ high-temperature ceramic fiber muffle furnace used in laboratories is commonly used for experiments such as sintering, ashing, and melting. It offers advantages such as fast heating and excellent heat preservation. The following provides relevant information:

High-Efficiency Insulation: Tianjin Test Instrument Co., Ltd. typically uses a vacuum-formed polycrystalline mullite fiber furnace chamber. This material has low thermal conductivity and low heat storage capacity, effectively reducing heat loss and improving energy efficiency while also facilitating rapid temperature increase.

Excellent Temperature Uniformity: Tianjin Test Instrument Co., Ltd. often uses a three-sided heating method using special alloy heating wires, such as the nickel-chromium-aluminum alloy OCr27AL7Mo2. This creates a relatively uniform temperature field within the furnace chamber, with a temperature distribution accuracy of up to ±1℃.

High Safety Performance. Tianjin Test Instrument Co., Ltd. features a variety of safety protection features, such as door-opening power-off and power-on delay, to prevent burns. Additionally, over-temperature alarms, menu lockout, and overcurrent and leakage protection effectively prevent equipment damage or accidents caused by malfunctions.

Precise Temperature Control: These instruments typically utilize microcomputer PID control technology and high-precision temperature sensors, such as K-type thermocouples, to achieve a temperature control accuracy of ±1℃ and a resolution of 1℃. They also support programmed temperature ramping and constant temperature functions to meet diverse experimental needs.

Some Models and Parameters from Tianjin Tester Instrument Co., Ltd.

Taking the MFLC1200℃ series ceramic fiber muffle furnace from Tianjin Tester Instrument Co., Ltd. as an example, some of its models and parameters are as follows:

MFLC-2/12D

PFLC-7/12P

MFLC-16/12T

Furnace Dimensions (mm) 200 × 120 × 80 300 × 200 × 120 400 × 250 × 160

Internal Volume (L) 2 7 16

Heating Power (kW) 1.5 3 6

Power Supply (50/60Hz) AC220V/7A AC220V/13.6A AC220V/27.3A

Temperature Control Mode: Single-stage digital display; Imported programmable digital display; 7-inch color touch screen programmable temperature control

Operational Specifications: Strictly follow the rated temperature indicated on the equipment nameplate. For example, the rated The maximum operating temperature of a 1200°C furnace should not exceed 1150°C. Control the heating and cooling rates. For a 1200°C medium- and high-temperature furnace, maintain a heating rate of 5-8°C/min. Open the furnace door only after the temperature has cooled to below 600°C. Push and pull the furnace door gently when opening and closing it. Avoid frequent opening and closing at high temperatures (>600℃), and keep the door open for no more than 30 seconds at a time.

Daily Maintenance: After each use, wait for the furnace chamber to cool below 100℃ and clean sample residue inside with a soft brush. Check the electric furnace wire for looseness and deformation every three months, and calibrate the thermocouple with a standard thermometer every six months. Check the furnace door seal weekly for aging, deformation, or detachment.

At this point, the muffle furnace beeps, indicating that the internal temperature has stabilized at 1195℃. Lin Yue suddenly realized that this non-equilibrium material behavior might solve the thermal barrier coating failure problem that had plagued the team for six months. She pressed the record button: "A breakthrough has occurred in the 147th experiment. It is recommended to start it immediately..." Before she finished speaking, the emergency pressure relief valve on the top of the furnace suddenly spewed out wisps of green smoke, which reflected a rainbow-like spectrum under the illumination of the laboratory ceiling light.
