Bayi Iron & Steel has been granted a utility model patent for a \"Device for Cleaning the Valves of the Observation Holes in Hydrogen-Rich Carbon-Cycle Oxygen Blast Furnaces.\" According to data from the Tianyancha app, Bayi Iron & Steel (600581) has obtained a new utility model patent; the name of this patent is \"Device for Cleaning the Valves of the Observation Holes in Hydrogen-Rich Carbon-Cycle Oxygen Blast Furnaces,\" with the patent application number CN202422172108.0. The patent was granted on August 8, 2025. Patent Abstract: This utility model belongs to the technical field of viewing ports for hydrogen-rich carbon circulation furnaces, and specifically discloses a cleaning device for the viewing port valves of hydrogen-rich carbon circulation oxygen blast furnaces. It includes a nozzle, with a purging port provided on the nozzle; a plug is embedded within this purging port, and the plug is connected to the nozzle via bolts. The nozzle is equipped with connection components for attaching it to other components, and an air pipe is fixed to the nozzle. A nitrogen tank is attached to this air pipe, and the nitrogen gas from the tank is discharged through the air pipe from the nozzle. Since there are four purging ports on the nozzle, when substances such as coke are not evenly distributed on the inner surface of the valve’s viewing port, the plug can be connected to the nozzle using bolts, so that the nitrogen gas ejected from the nozzle only cleans those areas of the valve’s inner surface where coke or similar substances are present. This solves the problem in existing technologies, where gases in the connection pipes cannot effectively clean away coke and similar substances when they are not evenly distributed on the valve’s inner surface. Since the beginning of this year, Bayi Iron & Steel has obtained 49 new patent approvals, a decrease of 47.31% compared to the same period last year. Based on the financial data in the company’s 2024 annual report, the company invested 701 million yuan in research and development in 2024, representing a 0.26% increase compared to the previous year. According to big data analysis by Tianyancha, Xinjiang Bayi Iron and Steel Co., Ltd. has invested in 5 companies in total and participated in 4,503 bidding projects ； Regarding property-related clues, there are 8 trademark records, 3,524 patent records, and 2 copyright records ； In addition, the company holds 172 administrative licenses.
