Base device capable of achieving automatic argon connection of steel ladle trolley

Abstract

The invention relates to a base device capable of achieving automatic argon connection of a steel ladle trolley in the technical field of iron and steel smelting. The base device comprises an installing base welded and fixed to a trolley supporting beam, wherein an upper supporting flat plate is fixed to the installing base, the upper surface of the upper supporting flat plate is detachably installed with a lower-portion connector for automatic argon connection together, the upper surface of the upper supporting flat plate is provided with a plurality of positioning grooves, each positioning groove is matched with a spring, the upper end of the spring is connected with the lower-portion connector for automatic argon connection, and the lower end of each spring is inserted into the corresponding positioning groove. The upper supporting flat plate is provided with a connecting yield hole for an air inlet pipe to penetrate through, a guiding connection pipe is built in the installing base, one end of the guiding connection pipe is detachably connected with the air inlet end of an air inlet pipe fitting, the other end of the guiding connection pipe is detachably connected with a delivery pipe, and an installing yield hole for the delivery pipe to movably penetrate through is formed in the installing base. The base device can ensure the installing stability of the lower-portion connector for automatic argon connection and does not affect the work of a weighing sensor while ensuring an automatic argon connection function.

Description

technical field [0001] The invention relates to the technical field of iron and steel smelting, in particular to a base for automatic argon connection of a ladle trolley. Background technique [0002] At present, the bottom blowing argon refining technology outside the furnace is generally used in the production of steelmaking converters. The molten steel that has been smelted in the converter is transferred to the ladle, and the argon gas with a certain pressure and flow rate is passed through the pipeline installed on the ladle. Blow continuously into the ladle from the bottom of the ladle. Filling the molten steel with argon can "stir" the molten steel, which can even the composition and temperature of the molten steel, improve the pouring performance of the molten steel, reduce the content of non-metallic inclusions and harmful gases, so as to achieve the effect of re-refining the molten steel. When the crane lifts the ladle to the trolley, it is mainly through manual o...

Problems solved by technology

However, since the supporting beam of the trolley is equipped with a weighing sensor, the ladle itself needs to give the weighing sensor a downward force during the installation process. Affected by the weighing sensor, there is a gap between the upper joint of the automatic argon connection and the lower joint of the automatic argon connection. Unable to achieve a reliable seal
