As the Al 2 O 3 content of the iron‐making raw materials increasing, the Al 2 O 3 content in the slag increases as well, which is the certain result in the development of the iron‐making process. Based on the slag which was from the 2# blast furnace in Hebei Qianan of China, 7 different kinds of B compositions were added. The viscosity values of the CaO ‐MgO‐Al 2 O 3 ‐SiO 2 ‐B 2 O 3 system were measured by using the torque. The SEM and EDS apparatus were used to observe the variation characteristics of the boronizing slag of the blast furnace. Viscosity mechanism model of the boronazing high‐alumina slag was got from the analysis of the EDS compositions. These detailed analysis including the influence on the slag forming components result from different B contents which shows the conclusion that the suitable B content makes good to the viscosity, melting temperature and stability of high‐alumina slag.
