Movement and position control of a lance

The lance for oxygen injection is moved into and out of the basic oxygen furnace shell through the exhaust hood. The lance’s actual penetration depth in the steel bath, as well as its maximum retracted and advanced positions, ensure optimal lance operation. This precise lance position information calls for on-line monitoring in the harsh conditions of a steel plant. A combination of a rugged inductive proximity sensor and an absolute multiturn encoder offers exact details about the lance’s position in the furnace and allows optimal positioning for ideal performance.
