Abstract
The utility model relates to metallurgy industry steel facility, in particular to molten steel container for reducing residual molten steel in the steel-smelting product. The wall of the molten steel container and the bottom of the molten steel container form an opening container. The bottom of the molten steel container is provided with water inlet low-lying region. The water inlet low-lying region is lower than the bottom of the molten steel container and is communicated with the water inlet. Because the density of the molten steel is larger than the steel slag, the molten steel focus on the water inlet low-lying region and the molten steel can be poured at maxima without the increased remainding slag quantity. The utility model has reasonable structure and can reduce the residual molten steel quantity and remainding quantity.
Description
Affiliated technical field:
The utility model relates to the ladle in the metallurgy industry steelmaking equipment, particularly STEELMAKING PRODUCTION.
Background technology:
During metallurgy industry was produced, it was a key factor that influences recovery rate of iron that ladle waters surplus always.Along with metallurgy industry is more and more higher to the requirement of steel quality to the attention and the process for making of steel quality, more and more stricter to the control of ladle quantity of slag under the middle bag.Because the effect of ladle beam later stage eddy current, the quantity of slag will certainly be brought the increase of molten steel loss under reducing.At present, all adopt flatly in the STEELMAKING PRODUCTION at the bottom of the ladle bag, because molten steel loss becomes area to be directly proportional with at the bottom of the ladle bag, so it is surplus many to cause ladle to water, the following quantity of slag is big.
The utility model content:
The utility model purpose provides the ladle that residual molten steel is watered in a kind of minimizing, reduces the area of ladle beam vortes interference in latter stage, waters surplus, the following quantity of slag thereby reduce ladle, solves the problems referred to above that background technology exists.
The technical solution of the utility model is: by forming Fengkai mouth container at the bottom of ladle wall and the ladle, be provided with low-lying district, the mouth of a river at the bottom of the ladle, low-lying district, the mouth of a river is lower than at the bottom of the ladle, and communicates with the mouth of a river.
Low-lying district, the mouth of a river is lower than at the bottom of the ladle, because molten steel density is bigger than slag, ladle beam molten steel in latter stage concentrates on low-lying district, the mouth of a river, can water molten steel to greatest extent, does not cause down increasing of the quantity of slag simultaneously again.
The utlity model has rational in infrastructure, can reduce ladle and water surplus, the following characteristics of the quantity of slag.
Description of drawings:
Fig. 1: the utility model embodiment front view
Fig. 2: the utility model embodiment vertical view
In the accompanying drawing, at the bottom of ladle wall 1, the ladle 2, low-lying district 3, the mouth of a river, the mouth of a river 4.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
In an embodiment, ladle wall 1 and 2 composition open containers at the bottom of the ladle, ladleful is 150 tons, ladle ground area is 5.5m
2, 2 are provided with low-lying district 3, the mouth of a river at the bottom of the ladle, and low-lying district, mouth of a river area is 1.75m
2, be lower than 60mm at the bottom of the ladle,, and 4 communicate in the mouth of a river.When steel ladle pouring, owing to low-lying district, the mouth of a river is lower than at the bottom of the ladle, and molten steel density is bigger than slag, ladle beam molten steel in latter stage concentrates on low-lying district, the mouth of a river, can water molten steel to greatest extent like this, ladle waters the surplus 50%-70% of minimizing, does not cause down increasing of the quantity of slag simultaneously again.
Claims (1)
1, the ladle of residual molten steel is watered in a kind of minimizing, and (2) form open containers at the bottom of ladle wall (1) and the ladle, it is characterized in that ladle at the bottom of (2) be provided with low-lying district, the mouth of a river (3), low-lying district, the mouth of a river (3) is lower than (2) at the bottom of the ladle, and communicates with the mouth of a river (4).
