[0002] A molten steel casting device is an important steel manufacturing equipment, which is used to inject high-temperature molten steel into a mold, and form the required steel products through cooling and solidification.

[0003] When casting a valve, the mold is installed at the lower part of the pouring container, and the molten steel is gradually injected into the mold through the pouring system. During this process, the molten steel will fill the entire mold cavity and gradually cool and solidify within a certain period of time to form a valve.

[0004] Currently, when pouring molten steel for valve casting, the molten steel needs to be injected into the mold cavity through the injection port. In the prior art, the molten steel is directly poured into the cavity through a ladle, which cannot accurately inject the molten steel into the mold. At the same time, it is necessary to inject the molten steel into the mold one by one manually, resulting in poor injection effect. Therefore, we propose a molten steel casting device for valve casting. Content of the Utility Model

Cooperating with multiple diversion tubes 601 is convenient for casting molds with different spacings, ensuring the casting efficiency.

[0026] To better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the specification drawings and specific embodiments.

[0027] The embodiments of the present utility model disclose a molten steel casting device for valve casting.
