Abstract
本实用新型公开了一种带有金属外壳的钢包，降低钢水热损失。本实用新型提供的钢包结构包括：耳轴、钢包壁、底吹气体入口和金属外壳，金属外壳包裹在钢包壁上，底吹气体入口设在钢包中部。本实用新型利用钢包散发出的热量加热底吹气体，升高底吹气体温度后再通入钢包可以缩小底吹气体与钢液的温度差，减少钢水温降，同时包壁与金属外壳间的气体形成隔热层有效的减少热损失。带有金属外壳的钢包使用寿命长、性能稳定，可以低成本应用于现有设备改造。
The utility model discloses a steel ladle with a metal shell, which reduces the heat loss of molten steel. The ladle structure provided by the utility model includes: a trunnion, a ladle wall, a bottom blowing gas inlet and a metal casing, the metal casing is wrapped on the ladle wall, and the bottom blowing gas inlet is arranged in the middle of the ladle. The utility model utilizes the heat emitted by the steel ladle to heat the bottom blowing gas, and after raising the temperature of the bottom blowing gas, it can be passed into the ladle to reduce the temperature difference between the bottom blowing gas and molten steel, reduce the temperature drop of molten steel, and simultaneously The gas forms a thermal insulation layer to effectively reduce heat loss. The steel ladle with metal shell has long service life and stable performance, and can be applied to existing equipment renovation at low cost.
Description
技术领域 technical field
本实用新型属于冶金设备。特别是涉及一种带有金属外壳的钢包。The utility model belongs to metallurgical equipment. In particular it concerns a ladle with a metal casing.
背景技术 Background technique
钢包不仅是运输钢液的容器，也是二次精炼的组成部分。钢水从炼钢炉盛入钢包后在进入精炼过程中会吹入氮气或氩气进行搅拌，气体进入钢包中被高温钢液加热，钢液温度降低，造成大量热损失。The ladle is not only a container for transporting molten steel, but also an integral part of secondary refining. After the molten steel is poured into the ladle from the steelmaking furnace, nitrogen or argon gas will be blown into it for stirring during the refining process. The gas enters the ladle and is heated by the high-temperature molten steel, and the temperature of the molten steel decreases, causing a large amount of heat loss.
现有的钢包主要由耐火砖、包壁，耳轴部分组成。在使用过程中，钢包包壁散热占钢水热损失的15—25%，减少这部分热损失可以有效的降低钢水的温降，节约生产成本。而用增加耐火材料和提高出钢温度的方法是不经济的。Existing ladle mainly is made up of refractory brick, cladding wall, trunnion part. In the process of use, the heat dissipation of the ladle wall accounts for 15-25% of the heat loss of molten steel. Reducing this part of heat loss can effectively reduce the temperature drop of molten steel and save production costs. It is uneconomical to increase the refractory material and increase the tapping temperature.
实用新型内容 Utility model content
本实用新型提供了一种带有金属外壳的钢包，降低钢水热损失。The utility model provides a steel ladle with a metal shell, which reduces the heat loss of molten steel.
本实用新型提供的一种带有金属外壳的钢包，其结构包括：耳轴、钢包壁，其特征在于还包括底吹气体入口和金属外壳，金属外壳包裹在钢包壁上，底吹气体入口设在钢包中部。The utility model provides a steel ladle with a metal shell. Its structure includes: a trunnion, a ladle wall, and is characterized in that it also includes a bottom blowing gas inlet and a metal shell. In the middle of the ladle.
底吹气体先进入钢包壁与金属外壳之间的空隙，利用钢包辐射的热量加热底吹气体，加热后的气体再通入钢包内搅拌钢液。The bottom blowing gas first enters the gap between the ladle wall and the metal shell, and the bottom blowing gas is heated by the heat radiated from the ladle, and then the heated gas is passed into the ladle to stir the molten steel.
本实用新型与现有同类设备相比，其有益效果体现在：Compared with the existing similar equipment, the utility model has the beneficial effects as follows:
利用钢包散发出的热量加热底吹气体，升高底吹气体温度后再通入钢包可以缩小底吹气体与钢液的温度差，减少钢水温降，同时包壁与金属外壳间的气体形成隔热层有效的减少热损失。带有金属外壳的钢包使用寿命长、性能稳定，可以低成本应用于现有设备改造。The heat emitted by the ladle is used to heat the bottom blowing gas. After raising the temperature of the bottom blowing gas and then passing it into the ladle, the temperature difference between the bottom blowing gas and the molten steel can be reduced, and the temperature drop of the molten steel can be reduced. At the same time, the gas between the cladding wall and the metal shell forms a barrier. Thermal layer effectively reduces heat loss. The steel ladle with metal shell has long service life and stable performance, and can be applied to existing equipment renovation at low cost.
