SUMMARY:Comparison of blast furnace operation in China and Europe
DESCRIPTION:There was about 1.28 billion tons of hot metal produced in 2019 with various operations of blast furnaces around the world.  The present paper describes similarities and differences in BF operation based on hands on experience and operational results. The focus is on large blast furnaces (≥12 m hearth, ≥3200 m3 IV).
The paper starts with comparing results in productivity, coke rate and total fuel rate. A comparison is made of:
-	The effect of BF size on operation results.
-	Raw materials being used, slag volume and composition as well as the effect of slag volume on PCI rates and productivity.
-	Operating philosophies: consistent versus variable blast volume.
-	Tuyere parameters like velocity and blast momentum.
-	PCI rates and oxygen enrichment.
-	Use of burden distribution.for optimizing BF operations. This includes the ferrous and coke layers that are being used as well as methods for using two sizes of sinter.
In the discussion the authors address the question what operators can learn from each other.

Note: this is the farewell lecture of Dr Maarten Geerdes, who leaves the BF community after turning 70 in March 2021
