Thermo Small Refractory Brick Resistance Trade Sensor Muffle Furnace

Product Description

thermo small refractory brick resistance trade sensor muffle furnace

Product Description

The SK2 series vacuum tube-type high temperature sintering furnace integrates the control system and the furnace chamber. The furnace lining uses vacuum formed high-purity alumina ceramic fiber material, and uses resistance wire / silicon carbide rod / silicon molybdenum rod as the heating element. The furnace tube traverses the middle of the furnace body as the furnace chamber. The two ends of the furnace tube are sealed with stainless steel flanges. The workpiece sample is heated in the furnace tube. The heating element is parallel to the furnace tube and is evenly distributed outside the furnace tube to effectively ensure the uniformity of the temperature field. Thermocouples (K/S/B type) with stable performance and long service life are used for temperature measurement to improve the accuracy of temperature control. It is a special equipment specially developed for the sintering, melting and analysis of metals, non-metals and other compound materials in the atmosphere or vacuum state by universities, scientific research institutes and industrial and mining enterprises.

The control panel of the furnace body has an intelligent temperature regulator, which controls the power switch, the main heating work/stop button, and is equipped with power and insurance indicator lights, voltage and current instructions, so as to observe the working status of the system at any time.

Application

Tube-type furnaces are mainly used in metallurgy, glass, heat treatment, lithium battery positive and negative materials, new energy, abrasive tools and other industries, and are professional equipment for measuring materials under certain temperature conditions. This furnace has simple structure, and is easy to operate and control, and capable of continuous production.
 

Advantages

SK2 series (1200ºC /1400ºC /1700ºC) tube-type furnace has the following advantages:

30-segment intelligent temperature control regulator, PID control, temperature control accuracy ±1 degree.
The temperature upper limit alarm can be set, and the main circuit can be automatically cut off when the temperature exceeds the upper limit.
High-purity alumina ceramic fiber is used as the furnace chamber material, which has good thermal insulation effect. The furnace tube can be quartz tube / stainless steel tube / corundum tube according to the temperature.
Single temperature zone, double temperature zone, three temperature zone and five temperature zone can be customized according to customer requirements.
Using KF flange, which has good sealing performance and high vacuum.
With RS232 interface, it can communicate with computer (optional).

Exterior design	The electric furnace adopts humanized design, has beautiful appearance, simple operation, and the outer paint layer uses a high-temperature baking process with plastic spraying. It has high temperature resistance, oxidation resistance, acid and alkali resistance. The color is chosen to be resistant to aging, and the appearance of the color will not fade due to long use.
Shell design	The shell of electric furnace adopts a double-layer forced air-cooling structure, so that the outer temperature of the furnace shell is close to room temperature when the electric furnace is working at the highest temperature, avoiding accidental damage.
Temperature control method	Adopt the most advanced temperature controller in the world: with 30-51 section programmable PID self-tuning, automatic heating, automatic cooling, no need to be on duty. RS-485 communication interface is also optional (connect to an ordinary computer to start, stop, pause heating, set heating curve, heating curve storage, historical curve records, etc.)
Temperature control safety	The electric furnace adopts coking circuit, module control, and dual-circuit protection (bias temperature protection, ultra-high temperature protection, broken couple protection, overcurrent protection, overvoltage protection and other protection functions) to make the electric furnace work stable, reliable and safe.
Heating rate	The maximum heating rate is 30°C/min, and 20°C/min is recommended.
Material of furnace chamber	Using the most advanced light alumina ceramic fiber in the world, it has excellent heat preservation effect, light weight, high temperature resistance, rapid cold and rapid heat resistance, no cracks, no crystallization, no slag, and no need to worry about pollution to the fired product. The energy saving effect is 60%-80% of the old electric stove.
Design of furnace chamber	The furnace chamber adopts a stepped assembly structure and incorporates the laws of mechanics, which effectively guarantees the uniform force of the furnace chamber during the heating process, ensures that the heat energy is not easily lost, and prolongs the service life of the furnace chamber.
Passable gas	All inert gases, mixed gases, nitrogen, carbon dioxide, water vapor, hydrogen, and oxygen…
Gas control	The air inlet can be provided with one or more air inlets, and each air inlet is provided with a needle valve connected to a vacuum gauge. The air outlet is connected with an air outlet, and all holes are equipped with needle valves. Equipped with a vacuum pump.
Sealing method	The 304 stainless steel flange is used, which is easy to install and unload, anti-oxidation, anti-acid and alkali, and double-layer sealing to ensure the tightness.
Warranty period	The electric furnace has a free warranty of 12 months (except for the heating element), and the heating element and cooling fan that are naturally damaged within 3 months are free to be replaced.
Accessories	Standard accessories: one vacuum pump, one crucible tongs, one pair of special high-temperature gloves, one instruction manual. Optional accessories: touch screen control, paperless recorder, remote communication control system.
Product certification	EU standard CE certification ISO 9001:2008 quality management system certification.
