Description

TECHNICAL FIELD

[0001] The utility model relates to the field of steel manufacturing, specifically relates to an improved drainage sand feeding platform. BACKGROUND

[0002] Drainage sand is a kind of filling material for the nozzle at the bottom of a ladle, and is an indispensable refractory material when tapping in an eccentric furnace. Its main functions include: dispersion flow performance: drainage sand has good dispersion flow performance, can be evenly distributed in the nozzle of the ladle, and ensures that molten steel can flow down smoothly. Refractory performance: drainage sand has high refractoriness, can maintain stability in high-temperature environment, and the service temperature is greater than or equal to 1750 DEG C. No sintering and no clogging: drainage sand will not sinter into a whole at high temperature, and will not clog the nozzle, ensuring that molten steel flows out smoothly. Chemical stability: drainage sand does not react with molten steel and alloy components, ensuring that the quality of molten steel is not affected. Automatic pouring: drainage sand can produce a thin sintering layer under the action of heat of molten steel, form a "shell", when the slide plate is opened, most of the unsintered sand in the nozzle falls freely, and at the same time, the "shell" is broken by the static pressure of molten steel, and molten steel flows out automatically, thereby achieving the drainage effect.

[0003] The addition of drainage sand usually needs to be manually poured into the ladle above the collecting hopper, and then poured into the ladle through the pipe. The drainage sand is usually packaged in small bags of 10 kg. Since the whole bag needs to be added from the pipe into the nozzle of the ladle during feeding, there are disadvantages in adding the whole bag, and the operator usually directly adds the whole bag into the collecting hopper at the upper part of the pipe. Since the pipe is inserted into the lower part of the work zone, the amount of pouring cannot be controlled, and only the whole bag can be poured, so that the amount of pouring is greater than the required amount, resulting in unnecessary waste.
