Description
钢包自动引流装置 Ladle automatic drainage device
技术领域 Technical field
本发明涉及一种应用于炼钢系统中的钢包自动引流装置。 The invention relates to a ladle automatic drainage device applied in a steel making system.
背景技术 Background technique
目前， 国内外的炼钢厂普遍采用从钢包上面向钢包水口座砖内投放引流砂的方法来达到 钢包自动引流的功能。 此种方法的缺点是引流砂浪费严重， 使用量过大， 并产生大量的粉尘 污染， 工序时间长， 操作环境恶劣。 At present, steel mills at home and abroad generally adopt the method of placing drainage sand from the ladle to the ladle nozzle brick to achieve the automatic drainage of the ladle. The disadvantage of this method is that the drainage sand is wasteful, the usage is too large, and a large amount of dust pollution is generated, the process time is long, and the operating environment is bad.
中国专利公开号： CN2700029Y; 公开日： 2005年 05月 18日， 实用新型名称为 "钢包流 钢道用引流棒"， 该申请案公开了一种钢包引流装置， 由上盖、 管体、 引流物料和下底组成圆 柱形棒体； 上盖与管体均由易熔的薄片形板材制成， 上盖与管体直径相当； 引流物料 （引流 砂） 装于管体内， 下底为易熔薄膜， 包扎在管体下部。 使用时从钢包水口插入。 该项实用新 型虽然能够防止钢渣堵塞流钢道， 但并不能达到自动引流的目的。 因为引流棒与水口、 水口 座砖之间必然有一定的缝隙或空间， 钢水流入缝隙会造成引流砂烧结层加厚加深， 开始浇注 时， 钢水静压力压不破烧结层， 导致钢包不能自动引流。 而在对钢水质量要求日益提高的今 天， 钢包自动引流是对引流砂或引流装置的最基本的要求， 因为如果钢包不能自动引流， 就 需要烧氧， 会加剧钢水的二次氧化， 导致夹杂物增加， 从而影响了钢水质量， 而且大大增加 了烧氧操作人员的安全隐患， 也会打乱正常的生产节奏； 另一方面烧氧管的消耗成本要比引 流棒高很多。 China Patent Publication No.: CN2700029Y; Publication Date: May 18, 2005, the utility model name is "Drainage rod for ladle flow steel road", the application discloses a ladle drainage device, which is covered by the upper cover, the pipe body, and the drainage The material and the bottom are composed of a cylindrical rod; the upper cover and the tube are made of a fusible sheet-shaped plate, and the upper cover is equivalent to the diameter of the tube; the drainage material (drainage sand) is installed in the tube body, and the lower bottom is fusible. The film is wrapped around the lower part of the tube. Insert from the ladle nozzle when in use. Although this new utility model can prevent steel slag from blocking the flow steel channel, it cannot achieve the purpose of automatic drainage. Because there must be a certain gap or space between the drainage rod and the nozzle and the nozzle brick, the molten steel flowing into the gap will cause the sintering sand to be thickened and deepened. When the pouring starts, the static pressure of the molten steel does not break the sintered layer, which causes the ladle not to be automatically drained. In today's increasingly demanding quality of molten steel, ladle automatic drainage is the most basic requirement for drainage sand or drainage equipment, because if the ladle can not automatically drain, it needs to burn oxygen, which will aggravate the secondary oxidation of molten steel, leading to inclusions. The increase, which affects the quality of the molten steel, and greatly increases the safety hazard of the oxygen-burning operators, and also disrupts the normal production rhythm; on the other hand, the consumption cost of the oxygen-burning tube is much higher than that of the drain rod.

钢筒 7外径比钢包滑板内径小 2mm， 便于插入水口； 在制作引流器时， 引流器的空间容 积应接近由钢包上滑板、 上水口、 水口座砖所围成的空间容积， 以此来确定整个引流器的长 度， 其目的是引流器内的引流砂流出后尽可能填满座砖上平面以下的容积。 The outer diameter of the steel cylinder 7 is 2mm smaller than the inner diameter of the ladle slide, which is convenient for inserting the nozzle; when making the diverter, the space volume of the diverter should be close to the space volume enclosed by the ladle on the ladle, the water inlet and the nozzle brick. The length of the entire drain is determined, the purpose of which is to fill the volume below the plane above the block as much as possible after the drain sand in the drain flows out.
使用时， 钢筒封口端 1向前， 侧孔 5向上， 沿钢包水口水平插入钢包内， 关闭水口； 此 时用于封闭圆筒侧孔 5的薄片或薄膜已受热熔融， 随着钢包的竖起， 引流器内的引流砂沿侧 孔 5流出， 充填进座砖、 水口和装置之间的缝隙、 空间； 当钢包开始浇注时， 打开滑动水口， 此时用于封闭钢筒下口 6的易熔薄膜已受热熔化， 筒内的引流砂从钢筒下口 6流出， 筒外的 引流砂又沿侧孔 5反流进钢筒内， 并从钢筒下口 6流出； 此时与钢水接触界面处的引流砂已 经烧结， 形成烧结层， 而由于引流砂已沿钢筒下口 6流出导致烧结层以下已空， 在钢水静压 力的作用下烧结层开始变形； 当水口完全打开后， 烧结层失去了钢筒的支撑继续变形， 当烧 结层变形达到一定程度时， 烧结层破裂， 钢水流出， 形成自动引流。 In use, the sealing end 1 of the steel cylinder is forward, the side hole 5 is upward, and is inserted horizontally into the ladle along the ladle nozzle to close the nozzle; at this time, the sheet or film for closing the side hole 5 of the cylinder has been melted by heat, with the vertical of the ladle The drainage sand in the drainer flows out along the side hole 5, filling the gap and space between the seat brick, the nozzle and the device; when the ladle starts to be poured, the sliding nozzle is opened, and at this time, the lower port 6 of the steel cylinder is closed. The fusible film has been melted by heat, and the drainage sand in the cylinder flows out from the lower mouth 6 of the steel cylinder, and the drainage sand outside the cylinder flows back into the steel cylinder along the side hole 5, and flows out from the lower mouth 6 of the steel cylinder; The drainage sand at the contact interface has been sintered to form a sintered layer, and since the drainage sand has flowed out along the lower mouth 6 of the steel cylinder, the sintered layer is empty below, and the sintered layer begins to deform under the static pressure of the molten steel; when the nozzle is completely opened, The sintered layer loses the support of the steel cylinder and continues to deform. When the deformation of the sintered layer reaches a certain level, the sintered layer is broken, and the molten steel flows out to form automatic drainage.
在本实施例中， 该钢筒由钢种为 Q235的普通钢材制成。 In the present embodiment, the steel cylinder is made of ordinary steel having a steel grade of Q235.
钢筒侧面开有一个或多个任何形状的侧孔， 目的是让引流砂能够顺利流出或再次流入钢 筒； 封闭钢筒下口的材料还可以用其他使用温度在 40 ° (：〜 1200 ° C的薄片或普通薄膜代替。 The side of the steel cylinder is provided with one or more side holes of any shape for the purpose of allowing the drainage sand to flow smoothly or into the steel cylinder again; the material of the closed steel cylinder can also be used at other temperatures of 40 ° (: ~ 1200 °). A sheet of C or a plain film is substituted.
