China has the ability to design and manufacture large blowers of 4000~5800m3
The China Machinery Industry Federation, under the commission of the National Development and Reform Commission, recently held a demonstration meeting focused on the localization of large-scale blast furnace blowers in China. Experts from Sinopec, Xi'an Jiaotong University, Zhejiang University, research institutions, and Shaanxi Blower (Group) Co., Ltd. attended the event. The meeting successfully reviewed the localized technical plan for blast furnace blowers with capacities over 4,000 m³, confirming that China now has the capability to design and manufacture such large-scale units. It was concluded that the entire process of designing and producing these blowers can be fully localized.
Blast furnace blowers are essential components in the power supply system of blast furnaces used in ironmaking. Large blast furnace blower groups refer to the power equipment supporting blast furnaces of 4,000 m³ or larger. These systems have an air volume ranging from 7,000 to 10,000 Nm³/min and require driving power between 30,000 kW and 60,000 kW. They typically include large air blowers, automatic control systems, electronic control systems, and drive machines. Globally, there are currently 20 large blast furnaces with capacities between 4,000 and 5,500 m³, and China owns four of them. However, the large-scale blowers required for these furnaces are still imported. As China's metallurgical industry continues to expand, more than 10 new blast furnaces in the same capacity range are either under construction or planned.
Shaanxi Blower (Group) Co., Ltd. is the only company in China capable of designing and manufacturing large-scale blast furnace blower units. To date, it has produced over 20 large blowers with air flow rates exceeding 7,000 Nm³/min, covering the requirements of 4,000 to 5,500 m³ blast furnaces. During the demonstration meeting, the expert panel highly praised the company’s production capabilities, quality assurance system, and after-sales service. They recommended that relevant government departments strengthen coordination and guidance in the localization of ultra-large blast furnace blowers and provide policy support to manufacturers and users who are willing to adopt and develop such critical equipment.
