Title: Innovations by Dong Shen
Introduction
Dong Shen is a notable inventor based in Oakville, CA, recognized for his contributions to electrical engineering and furnace technology. With a total of three patents to his name, he has made significant advancements in optimizing arc furnace operations.
Latest Patents
One of Dong Shen's latest patents is focused on open arc condition mitigation based on measurement. This innovative system measures parameters of the electricity drawn by an arc furnace and analyzes these parameters to provide indicators of whether arc coverage has been optimized. Key factors related to this optimization include electrode position, charge level, slag level, and slag behavior. By ensuring that arc coverage is optimized, the system helps maintain a stable arc cavity and avoid open arc conditions, thereby protecting the internal linings of the furnace walls and roof from excessive wear and tear.
Another significant patent by Dong Shen is the line control circuit configuration. This configuration involves a series of switches that allow for switching between a series-connected thyristor switch and reactor and a parallel-connected thyristor switch and reactor. This setup enables a controlled high-impedance circuit configuration, which is particularly beneficial for cold furnace start-ups and furnace idling. As a result, there is a reduced need for additional equipment such as startup transformers and temporary specialty electrical apparatus.
