Problems solved by technology
The disadvantages are that the structure of the sand storage device is complicated, the shell consumes a lot of materials, and it is inconvenient to manufacture and use; especially, there is no drainage sand in the nozzle of the ladle, and the molten steel is poured into the ladle and directly poured into the nozzle, and the molten steel is easy to condense in the nozzle. It is because the molten steel refining delay time is long, and the molten steel in the nozzle is more likely to solidify, which seriously affects the pouring of molten steel.

The invention discloses an umbrella-shaped steel ladle casting combination drainage plug, and relates to a steel ladle nozzle casting starting drainage device. The umbrella-shaped steel ladle casting combination drainage plug is characterized by being composed of an umbrella-shaped upper-mounted drainage sand pocket, outer wrapping skin, fastening plate strips and a lower-mounted drainage sand pocket. The upper-mounted drainage sand pocket is formed by an umbrella framework and a flexible metal wire mesh pocket, when the umbrella framework is folded, the upper-mounted drainage sand pocket is in a rod strip shape, and when the umbrella framework is unfolded, the upper-mounted drainage sand pocket is in an inverted cone shape. The fastening plate strips are evenly arranged on the lower portion of the umbrella framework, the lower-mounted drainage sand pocket is arranged in a cavity defined by the fastening plate strips, and the upper portion of the lower-mounted drainage sand pocket is jointed with the upper-mounted drainage sand pocket. When the umbrella-type steel ladle casting combination drainage plug is used, the fastening plate strips are fastened to the inner wall of a nozzle, and the umbrella-shaped upper-mounted drainage sand pocket covers the nozzle. The umbrella-shape steel ladle casting combination drainage plug has the advantages of being novel in conception, simple and reasonable in structure, stable and reliable, being manufactured in a split mode, being capable of being assembled in use, convenient to manufacture, store and convey, low in cost, accurate in arrangement, convenient to use, high in efficiency, less in steel using quantity and high in drainage sand using rate, effectively preventing residues and remaining steel from covering or being soaked into the nozzle to block the nozzle, being smooth in casting and guaranteeing smooth implementation of production.
Description
technical field [0001] The invention belongs to a casting melt container, in particular to a casting drainage device at the bottom nozzle of a ladle. Background technique [0002] Casting is an important process in steelmaking production. Successfully smelted molten steel is poured into ladles and cast directly or after refining. In the early days, the nozzle at the bottom of the ladle used a stopper rod to control and adjust the molten steel, and the pouring started smoothly. Because the movement of the stopper rod was difficult to control, the plug head was easy to fall off and was discarded. Most factories now use the sliding nozzle to intercept and control the casting of the ladle. In order to prevent the remaining steel, residue and other debris in the ladle from blocking the ladle nozzle (hereinafter referred to as the nozzle) and ensure smooth pouring, a special person is set up at the tapping station to throw it at the ladle nozzle. Drainage sand in bags. The disad...
