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.
Tube-typed 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. The furnace has simple structure, and is easy to operate and control, and capable of continuous production.
| Product Usage | It is widely used in scientific research and small batch production of enterprises and institutions, as well as ceramics, metallurgy, electronics, glass, chemical industry, machinery, refractory materials, new material development, special materials, and building materials involved in scientific research and teaching in colleges and universities. | ||
| Temperature | 1200ºC | 1400ºC | 1700ºC |
| Temperature control accuracy | ±1ºC | ±1ºC | ±1ºC |
| Thermocouple and measuring range | K type(0-1200ºC) | S type(0-1600ºC) | B type(0-1820ºC) |
| Heating element | Resistance wire | Silicon carbide rod | Silicon molybdenum rod |
| 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. | ||
