On the occasion of World Intellectual Property Day, the Annike cone-column composite top-burning hot blast stove independently designed and developed by Zhengzhou Annike Industrial Co., Ltd. was approved by Ukraine's international patent. This is the third international patent obtained by Annike cone-column composite top-burning hot blast stove after Japan and Russia.
Annike cone-column composite top-fired hot blast stove integrates more than 60 patents and proprietary technologies of Annike. It has been systematically developed around hot problems such as low air temperature, low thermal efficiency, high gas consumption, high NOx emission value, dislocation of burner nozzle, collapse of hot air outlet, sinking of lattice brick, and short service life of hot blast stove caused by deformed pipe system, it has completely solved the pain points of frequent blast furnace shutdown and high cost before iron due to the above problems. With the technical advantages of "high air temperature, long life and low energy consumption", it has helped the green development of the iron and steel industry. More than 200 hot blast furnace projects from 600m to 3000m have been newly built and renovated at home and abroad with EPC general contracting mode. Its integrated core key technology has won the first prize of Henan Science and Technology Progress Award, A number of provincial and ministerial awards, such as the first prize of the Metallurgical Science and Technology Award, are highly consistent with the theme of "Innovation for a Green Future" on this World intellectual property Day.
The approval of Ukraine's international patent, coupled with the previous international patents of Japan and Russia, will surely promote Anneke cone-column composite top-burning hot blast stove technology to completely break through foreign technical barriers and provide more reliable technical support for the world's blast furnace ironmaking! Anneke will always adhere to the mission of continuously promoting the technological development of blast furnace hot blast stove and the progress of refractory technology, and strive to become the preferred service provider of global high temperature industry.
