Heating rings
Description
Ceramic heating rings made of silicon nitride can be produced with an outer diameter of up to 300 mm. A typical extent of the rings is 5 mm. The good thermal conduction and the low thermal mass of the ceramic material allow extremely fast heating rates, a uniform temperature distribution and high control accuracy. The high strength of hot-pressed silicon nitride guarantees high stress resistance and excellent wear resistance at short processing times. We provide heating rings for operating in the open air at temperatures up to 500 °C. Higher temperatures (if required) could be achieved by developing specific technical solutions.
Customized design
Our in-house designs make any modification in size (inner and outer diameter) or performance simple and convenient. Mounting-bracket holes and openings for temperature regulation can be added to the design. Our heating rings come already flat ground, however they can be ground further up to a flatness of < 10 μm to meet specific requirements. A variety of shapes formed to the contour of the product or tool to be heated are possible as well.
