Muffle Furnaces with Embedded Heating Elements

Minimum Order
Product Description
1.tMaximum temperature: 1000℃

2.tAdopting vacuum molding technology, the heating wire is inlaid in the inside surface of the ceramic board and the chamber lining is once forming, preventing contamination by the volatile matter.

3.tThe heating wire is set in the four sidewalls inside the chamber. Adopting special insulating design,

4.tHave double-layer housing. The heat is insulated by the circulating air, so the temperature of the outside surface is very low.

5.tMoveable pulling block is set between the furnace body and the controller, which is convenient for putting the fire-screen door and sinter.

6.tDesigned of patent technique, the chamber is replaceable, and the user can adjust the position of the chamber freely. The door and the chamber of the furnace are perfectly sealed.

7.tHave automatic power failure protective function once the door is open. Have over temperature alarm function. Have power failure function once the thermocouple is damaged. Have controlling function with the built-in parameter pass code.

8.tHeating rate: 10-30℃/min. 30-segment automatically heating up programs

9.tProvide RS-485 communication port and Sigma data management software, which can record the history data and the temperature rising curve, correct the temperature deviated error, and manage multi-equipments and remote failure analysis.

10.tMultiple safety protective design. Itu2019s very safe and durable.

11.tOptional door: side opening door and parallel pulling door.

Extra option:

1.tObservation hole: The changing process can be observed by the observation hole.

2.tExhaust chimney

3.tGlass tube flow-meter, inlet pipe and outlet pipe

4.tSet up and debugging, training

LuoYang Sigma Furnace Co.,Ltd. was established on the basis of Luoyang Sigma Instrument Manufacture Co., Ltd, which was founded in 1999 and located in Luoyang, a beautiful ancient city. Covering an area of 6.6 acres, owns 8000 m2 standardized plant and office buildings, 1500m2 administrative and marketing center and 1500m2 ultra-high temperature engineering and technical research and development center for ultra-high temperature furnaces. It also possesses two advanced production lines of lab furnace and industrial furnace, a production line of ceramic fiber board and furnace chamber and one of processing ultra-high temperature ceramic fiber.

Up to now, being high-tech enterprise of Henan province, we have got 50 technology patents and many intellectual properties.

In 2011, cooperated with Henan measuring academy of sciences, we established the ultra-high temperature engineering technology center of Henan Institute of Metrology, which is the first development and testing organization to measure 1800℃ ultra-high temperature and test ultra-high temperature material’s property at home and abroad.

In 2010 we established an ultra-high temperature engineering technology center, which can be engaged in various types of sintering experiments at range of 1000-3000 degree Celsius. It is the first ultra-high temperature laboratory in China opening to both home and abroad.

In 2010, we invented zirconium diboride composite ceramic heating element and zirconium diboride composite ceramic thermocouple, the maximum working temperature can reach to 2600 degree Celsius and can be used under both in vacuum and oxidizing atmosphere. This technology made the history of measuring the maximum temperature in contact-type under oxidizing atmosphere.

We have been committed to researching and producing ultra-high temperature measurement, ultra-high temperature heating element, ultra-high temperature thermocouple, ultra-high temperature resistance furnace and ultra-high temperature ceramic composite materials. On the field of theoretical study on ultra-high temperature and ultra-high-temperature production, now and in a long time in the future, we will be in the forefront of ultra-high temperature. We are looking forward to cooperating with more workers of ultra-high temperature field.

China is a world factory with lower labor costs and resources, as well as our first-class technology, which will be known around the world. Now a new international brand of ultra-high-temperature field is forming and developing. We sincerely hope to establish long-term cooperation with more customers.

Our sigma company with meeting the full reasonable satisfactory needs of customer as the service concept,and has been praised by users.
Thank you for your concern Sigma company, sincerely welcome you to purchase Sigma products.
