Pressure tank for bottom gating steel casting

Abstract

The invention provides a pressure tank for bottom-pouring cast steel, which comprises a tank body and a tank top cover connected sealingly with the tank body, the tank body is provided with at least a gas pressure adjusting opening, a molten steel ladle with opening at top part is arranged in the tank body, two molten steel channels are arranged on inner wall of the molten steel ladle, the opening at lower end of the molten steel channel is arranged at bottom part inside the molten steel ladle, the opening at upper end of the molten steel channel is arranged at top part of the molten steel ladle, the opening at upper end of the molten steel channel is connected sealingly with a molten steel in-out interface, the upper part of the molten steel in-out interface is penetrated through the tank top cover, the stability of molten steel temperature and the stability of each process parameter in the pressure tank ensure product quality, moreover the liquid level of the molten steel in the pressure tank is stable so as to be easy for control when pouring, the design of the pressure tank meets the need of continuous production, so that production efficiency is improved greatly and economic efficiency is large.

Description

technical field [0001] The invention relates to pouring equipment used in the foundry industry, in particular to a pressure tank used for bottom pouring of steel castings. Background technique [0002] At present, in the field of casting, especially in the field of steel casting, low-pressure bottom injection technology is rarely used to cast castings. Although it is used in the casting of train wheels, continuous production has not been realized. The technical scheme is not perfect, and various technical indicators cannot be effectively controlled. Furthermore, the pouring machine used for bottom pouring has the defect that it cannot work continuously, resulting in low production efficiency, and the instability of various process parameters makes the product quality uncontrollable; these defects greatly restrict the bottom pouring The development of technology has also affected the application level of casting technology to a certain extent. [0003] In order to solve the ...
