Abstract

The invention relates to a soft skimming plug which comprises a central steel tube, a cold-rolled stamped steel sheet, a compressible movable cold-rolled stamped steel sheet, a refractory plastic material and a plastic film, wherein the cold-rolled stamped steel sheet is welded at the front end of the central steel tube; the compressible movable cold-rolled stamped steel sheet is sheathed on the back end of the central steel tube and can slide along the central steel tube; the refractory plastic material is arranged between the cold-rolled stamped steel sheet and the compressible movable cold-rolled stamped steel sheet; and the plastic film is wrapped outside the refractory plastic material.

Description

technical field [0001] The invention relates to the technical field of metallurgy, in particular to a soft slag stopper and a manufacturing method thereof. Background technique [0002] In recent years, varieties of steel with high added value have become popular. Compared with the steelmaking production process of ordinary steel, variety steel has higher requirements on the steelmaking production process. The high requirements of the steelmaking production process inevitably include high requirements for refractory materials, and one of the key factors is to ensure that the requirements for the amount of slag discharged from the converter are met. [0003] In steelmaking production, effective measures to reduce the amount of slag after tapping can not only greatly reduce the consumption of alloys, but also create favorable conditions for subsequent operations and reduce the difficulty of operation, especially in the production of variety steel. The significance of tapping...
