Description

Sublance probe structure

Technical Field

The application relates to the technical field of steelmaking, in particular to a sublance probe structure.

The converter sublance system becomes a main control system of modern automatic steel making, and the sublance probe and the system thereof can be used for measuring the molten steel temperature of a molten pool, the oxygen activity of the molten steel and the carbon content of the molten steel and taking out a molten steel sample. The indexes for evaluating the service performance of the sublance probe comprise: a connection success rate; the success rate of constant temperature; the success rate of oxygen determination; the sampling success rate; and measuring accuracy. Wherein the success rate of the connection is the basis, the first step in the use of the probe is that the structure of the sub-gun probe must be successfully connected with the holder of the system. Normally, the holder is in a vertical position, in which the connections of the sublance probe structure to the holder are very power intensive. As the service life of the holder increases, the holder is subjected to high temperature for a long time and repeatedly breaks slag, and certain distortion is generated. Meanwhile, as the converter mouth becomes smaller, the holder also touches the converter mouth during operation, thereby generating deformation. In practical use, the holder cannot be in a vertical state usually due to complicated conditions, and the connecting power of the probe is seriously influenced.
