Tangshan Outstanding Kiln Co., LTD obtained three Chinese patents

       News came from China Intellectual Property Office, three patents have been approved at Tangshan Outstanding Kiln Co., LTD, three patents and their functions are: "tunnel kiln temperature difference balancing device" to minimize the kiln temperature, which can improve product yield and quality from a good role in promoting. "Sealed tunnel kiln surge composite device" may be better to regulate the kiln car pressure from below, so as to protect the safe operation of the kiln car for a long time. "Tunnel kiln with side-stream regulator device" is particularly suitable for solving the tunnel kiln sponge iron reduction with positive pressure reduction is too large, and temperature rise smoke impeded the state is difficult.
