Description
Technical Field
The utility model relates to a steel smelting equipment, especially a knapsack formula hot metal bottle anticollision structure.
Background
In the technical field of steel smelting equipment, a hot metal tank is a device for collecting and conveying molten iron of blast furnace ironmaking products and is used on medium and small blast furnaces. The hot metal ladle is in a straight cylinder shape, the outside of the hot metal ladle is formed by rolling and welding steel plates, and the inside of the hot metal ladle is built with refractory bricks. At present, domestic large and medium-sized steel plants generally execute a 'one-pot-to-one-end' process flow, namely: the hot metal ladle for receiving molten iron in the blast furnace and the hot metal ladle of the converter are the same tank car, the hot metal ladle directly receives molten iron from a blast furnace casting yard and is transported to a steelmaking process, the molten iron is directly poured into the converter after desulfurization in the hot metal ladle through steelmaking without passing through a metal mixer, and the hot metal ladle has the characteristics of simplification, high concentration and short fluidization. But at the same time, a problem which troubles the steel industry occurs: in the process of pouring molten iron close to the converter by the hot metal ladle, the ladle body and the hoop at the lower part of the ladle nozzle are easy to collide and deform, and the side, close to the converter, of the hot metal ladle shell, which is poured for a long time, cracks, so that serious potential safety hazards appear.
The production line must be forced to be off line when the safe use standard cannot be met, otherwise, the turnover of a hot metal ladle is influenced, the smelting rhythm of tapping and a converter of a blast furnace is disturbed, and the integral production and operation of enterprises are further influenced.
Disclosure of Invention
The utility model aims at providing a simple structure, safe in utilization, can prolong hot metal bottle life's knapsack formula hot metal bottle anticollision structure.
The utility model discloses a knapsack formula hot metal bottle anticollision structure, including hot metal bottle body steel sheet, the inside resistant firebrick of hot metal bottle, its characterized in that, hot metal bottle middle part lateral surface sets up the arc steel sheet staple bolt, and staple bolt upper portion protection knapsack and middle staple bolt lower part protection knapsack are do not equipped with in the arc steel sheet staple bolt upper and lower part of the external working face of hot metal bottle, and the counter weight knapsack is established in the hot metal bottle another side with middle staple bolt upper portion protection knapsack, middle staple bolt lower part protection knapsack symmetry.
The utility model discloses a knapsack formula hot metal bottle anticollision structure through set up arc steel sheet staple bolt, middle staple bolt upper portion protection knapsack, middle staple bolt lower part protection knapsack at the hot metal bottle lateral surface, has strengthened the structural strength of hot metal bottle, can avoid hot metal bottle commentaries on classics to take place to warp with the converter collision, improves the life of hot metal bottle greatly.
