Description
所属技术领域：Technical field:
本实用新型涉及冶金行业炼钢设备，特别是炼钢生产中的钢包。The utility model relates to steelmaking equipment in the metallurgical industry, in particular to a steel ladle in steelmaking production.
背景技术：Background technique:
冶金行业生产中，钢包浇余一直是影响金属收得率的一个重要因素。随着冶金行业对钢水质量的重视及炼钢工艺对钢水质量的要求越来越高，对钢包到中包下渣量的控制越来越严格。由于钢包注流后期涡流的作用，减少下渣量势必会带来钢水损失的增加。目前，炼钢生产中钢包包底均采用平底，由于钢水损失与钢包包底成面积成正比，所以造成钢包浇余多，下渣量大。In the production of metallurgical industry, ladle pouring has always been an important factor affecting the metal yield. As the metallurgical industry pays more attention to the quality of molten steel and the steelmaking process has higher and higher requirements on the quality of molten steel, the control of the amount of slag from the ladle to the tundish is becoming more and more stringent. Due to the effect of eddy current in the later stage of ladle injection, reducing the amount of slag will inevitably increase the loss of molten steel. At present, the bottom of the ladle is flat in steelmaking production. Since the loss of molten steel is proportional to the area of the bottom of the ladle, there is too much pouring of the ladle and a large amount of slag.
实用新型内容：Utility model content:
本实用新型目的是提供一种减少浇余钢水的钢包，减少钢包注流末期涡流影响的面积，从而减少钢包浇余量、下渣量，解决背景技术存在的上述问题。The purpose of the utility model is to provide a steel ladle that reduces excess pouring of molten steel, reducing the area affected by the eddy current in the final stage of ladle pouring, thereby reducing the amount of excess pouring and slag in the ladle, and solving the above-mentioned problems in the background technology.
本实用新型的技术方案是：由钢包壁与钢包底组成封开口容器，钢包底上设有水口低洼区，水口低洼区低于钢包底，并与水口相通。The technical scheme of the utility model is: a closed container is formed by the ladle wall and the bottom of the ladle, and a low-lying area of the nozzle is arranged on the bottom of the ladle, and the low-lying area of the nozzle is lower than the bottom of the ladle and communicates with the nozzle.
水口低洼区低于钢包底，由于钢水密度比钢渣大，钢包注流末期钢水集中在水口低洼区，可最大限度的把钢水浇完，同时又不造成下渣量的增多。The low-lying area of the nozzle is lower than the bottom of the ladle. Since the density of molten steel is higher than that of steel slag, the molten steel is concentrated in the low-lying area of the nozzle at the end of the ladle pouring, so that the molten steel can be poured to the maximum without increasing the amount of slag.
本实用新型具有结构合理、能够减少钢包浇余量、下渣量之特点。The utility model has the characteristics of reasonable structure, and can reduce the ladle pouring surplus and slag discharge.

附图中，钢包壁1、钢包底2、水口低洼区3、水口4。In the accompanying drawings, a ladle wall 1, a ladle bottom 2, a nozzle low-lying area 3, and a nozzle 4.
具体实施方式：Detailed ways:
以下结合附图，通过实施例对本实用新型作进一步说明。Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
在实施例中，钢包壁1与钢包底2组成开口容器，钢包容量为150吨，钢包地面积为5.5m2，钢包底2上设有水口低洼区3，水口低洼区面积为1.75m2，低于钢包底60mm，，并于水口4相通。当钢包浇注时，由于水口低洼区低于钢包底，且钢水密度比钢渣大，钢包注流末期钢水集中在水口低洼区，这样可最大限度的把钢水浇完，钢包浇余可减少50％-70％，同时又不造成下渣量的增多。In the embodiment, the ladle wall 1 and the ladle bottom 2 form an open container, the ladle capacity is 150 tons, the ladle floor area is 5.5m 2 , the ladle bottom 2 is provided with a nozzle low-lying area 3, the area of the nozzle low-lying area is 1.75m 2 , It is 60mm lower than the bottom of the ladle, and communicates with the nozzle 4. When the ladle is poured, since the low-lying area of the nozzle is lower than the bottom of the ladle, and the density of the molten steel is higher than that of the steel slag, the molten steel is concentrated in the low-lying area of the nozzle at the end of the ladle pouring, so that the molten steel can be poured to the maximum extent, and the remaining pouring of the ladle can be reduced by 50%- 70%, while not causing an increase in the amount of slag.
