Recently, it is known that the three invention patents applied by CIE including “a kind of circular cooler”, “a kind of grate plate unit for pallet of circular cooler and grate plate for pallet” and “ a kind of floating mechanism and circular air duct end seal” have been authorized successively recently. The patents are applied and implemented around “the new type of liquid seal circular cooler” developed independently by CIE.

The “new type of liquid seal circular cooler” technology is in a world leading level and has complete proprietary intellectual property rights, it is an important breakthrough in current domestic and foreign sinter cooling equipment technology, and the world technology difficulty on large area dynamic sealing of circular cooler was solved. Centering around the independent innovation achievement, CIE has arranged over 100 patents, including 3 foreign patents and 62 Chinese patents. These patent technologies have been fully implemented by CIE, their industrial applications have been realized in over 10 domestic enterprises like Jisteel, Liansteel, Pansteel, Nansteel and Longsteel etc. and they haven been sold to foreign sintering project market with a wide prospect.
