description The invention discloses a quick and safe measurement method for a lance position of an oxygen lance, belongs to the technical field of converter steel-making technology, and aims to solve the problems that the lance position of the oxygen lance is not accurate, the measurement time is longer, a measurement process is more dangerous and the measurement precision is low in a practical production process are solved. The technical scheme is that through the processes of acquiring the absolute lance position heights of the oxygen lance and an auxiliary lance, measuring the height difference of the oxygen lance and the auxiliary lance and calculating error values of the absolute lance position heights of the oxygen lance and the auxiliary lance, by combining with the calculated error values and the liquid level height tested by the auxiliary lance, an actual height value of a lance head of the oxygen lance to molten steel liquid level in a blowing process can be calculated. The quick and safe measurement method dis
