1200c 1800c reatment electric ceramic fiber crucible for muffle resistance furnace trade sensor
The muffle furnace is a universal heating equipment, which can be divided into box furnace, tube furnace and crucible furnace according to its appearance.
The muffle furnace is a cyclic operation type. It is used for the element analysis and determination of laboratories, industrial and mining enterprises, and scientific research units and for heating during the quenching, annealing and tempering of general small steel parts. The high-temperature muffle furnace can also be used for the sintering, dissolution, analysis and other high temperature heating of metals and ceramics.
Working Principle
The working principle of the box-type high-temperature sintering furnace (SX2 series): After the temperature measuring element thermocouple converts the temperature into an electrical signal (voltage), it is connected to the microcomputer temperature controller. The temperature controller compares this signal with the programmed value, and then the microcomputer generates a control signal that reflects the temperature change of the furnace after calculating the difference, the positive and negative values, and the time. Use this signal to drive electrical components (power modules, solid-state relays, AC contactors, etc.) to achieve the purpose of controlling the furnace temperature. The high-precision PID program is used to automatically control the entire process and digitally display the furnace temperature and process information.
According to the different heating elements used, three temperature ranges are reached, namely 1200ºC 1400ºC, and 1700ºC. At 1200ºC, molybdenum-containing resistance wires are used as heating elements. At 1400ºC, silicon carbide rods are used as heating elements. At 1700ºC, silicon molybdenum rods are used as heating elements.
Product Application
(1) Thermal processing, industrial workpiece processing, cement, building materials industries, and thermal processing or treatment of small workpieces.
(2) Pharmaceutical industry: used for drug inspection, pretreatment of medical samples, etc.
(3) Analytical chemistry industry: as sample processing in water quality analysis, environmental analysis and other fields. It can also be used for petroleum analysis.
(4) Coal quality analysis: used to determine moisture, ash, volatile content, ash melting point analysis, ash composition analysis, element analysis. Can also be used as a general ashing furnace.
Product Features
