  • Detail

On the basis of digesting and absorbing imported technology and independent innovation, JINZI Tianzheng Intelligent Control Co., Ltd. has rich experience in the design, development and commissioning of blast furnace automation. We are responsible for 70% of the computer software of Baosteel's No.2 blast furnace. The automation project of Baosteel's No.3 blast furnace we participated in is in a leading position in China and has the world's advanced level. The automation system of the 1200 cubic meter blast furnace main process line of Chongqing Iron and Steel Co., Ltd. is the first large-scale blast furnace "three electricity" system project contracted by domestic forces in China, with the strong support of the state. The automation system of Meishan blast furnace is also contracted by our company, and the full PLC scheme and full CRT operation of blast furnace are realized for the first time in China

we can provide complete sets of automatic systems and technologies suitable for large, medium and small blast furnaces

complete sets of blast furnace automation technologies and systems include:

1 Blast furnace automatic control system
