Abstract
A modular metalmaking lance having a pre-fabricated 'plug-in' lower sections. The plug-in section is preferably of sufficient length to ensure that the joint between a plug-in section and an upper lance section is not in the area of the lance that typically is damaged in refining service. At the same time, the plug-in section is preferably short enough to be transported from an off-site assembly/repair shop to the refining shop via standard-length cargo trucks or truck-trailer rigs used throughout the world.
