Device and method for preventing molten steel from splashing during casting starting

Abstract

The invention relates to a device for preventing molten steel from splashing during casting starting. The device comprises a large ladle water gap machine part (2), a large ladle water gap, a first large ladle water gap sliding plate (3), a second large ladle water gap sliding plate (6), a sliding operating rod (7), a large ladle water gap fixing device (12), a hydraulic shaft (11), a hydraulic cylinder (9), a hydraulic cylinder fixing device (8) and a large ladle long water gap (5), wherein the large ladle water gap machine part (2) is mounted at the bottom of a steel ladle (1); the large ladle water gap fixing device (12) is arranged at the external part of the large ladle water gap machine part (2) in a sleeving manner; part of large ladle water gaps in the large ladle water gap machinepart (2) is provided with an opening; the large ladle long water gap (5) is hung at the lower part of a large ladle lower water gap (4); the first large ladle water gap sliding plate (3) is fixed onone side of the opening; the second large ladle water gap sliding plate (6) is fixedly connected with one end of the sliding operating rod (7); the other end of the sliding operating rod (7) is connected with the hydraulic shaft (11) in a sleeving manner; and the hydraulic cylinder (9) is fixed at the bottom of the steel ladle (1) through the hydraulic cylinder fixing device (8).

Description

technical field [0001] The invention belongs to the technical field of metallurgy, and in particular relates to a device and method for preventing pouring and spraying steel. Background technique [0002] In the continuous casting production process of traditional steelmaking plants, ladle pouring operation is one of the important links in the continuous casting production process. At present, when the steel drawing operator of the continuous casting machine starts pouring in the ladle, he relies on the experience of the workers to direct the steel drawing operator to complete the pouring operation. Often, the operator does not control the stroke of the hydraulic cylinder in place, and the ladle nozzle is too high. Small or too large, resulting in accidents such as small casting flow, low liquid level and molten steel splashing, not only need to frequently replace the long nozzle of the ladle, resulting in consumption of refractory materials; but also need to open the long n...

At present, when the steel drawing operator of the continuous casting machine starts pouring in the ladle, he relies on the experience of the workers to direct the steel drawing operator to complete the pouring operation. Often, the operator does not control the stroke of the hydraulic cylinder in place, and the ladle nozzle is too high. Small or too large, resulting in accidents such as small casting flow, low liquid level and molten steel splashing, not only need to frequently replace the long nozzle of the ladle, resulting in consumption of refractory materials; but also need to open the long nozzle of the ladle frequently Pouring, resulting in the oxidation of molten steel, which affects the quality of molten steel and slab, not only affects production efficiency, but also lays a safety hazard for safe production
