Built-in heat preservation type molten aluminum transfer ladle

Abstract

The invention discloses a built-in heat preservation type molten aluminum transfer ladle which comprises a transfer ladle shell and a transfer ladle cover, a ladle nozzle is installed on the upper portion of the transfer ladle shell, a fork conveying hole is formed in the lower portion of the transfer ladle shell, an anti-sticking inner container is installed in the transfer ladle shell, a heat preservation layer is installed between the transfer ladle shell and the anti-sticking inner container, the anti-sticking inner container is made of a graphite crucible, and the transfer ladle cover is made of a stainless steel material. The heat preservation layer is made of fire-resistant asbestos. The transfer ladle shell and the transfer ladle cover are connected through a hinge assembly, and a spring assembly is arranged at the tail end of the hinge assembly. The problem that aluminum oxide crystals are difficult to clean is solved by using the anti-sticking inner container made of a graphite crucible material and the characteristic that graphite is not stuck to aluminum, and the quality of molten aluminum is improved by solving oxidized slag inclusion; a hinge and a spring assembly are ingeniously applied to the transfer ladle cover, a buffering effect is achieved during opening and closing, and the service life is prolonged; the heat preservation layer is made of fire-resistant asbestos, the weight of the transfer ladle is reduced, the aluminum water capacity is correspondingly increased, production inconvenience is improved, and the difficult problems of aluminum alloy casting production are solved.

Description

technical field [0001] The invention relates to an aluminum water transfer bag applied to aluminum alloy casting. Background technique [0002] Aluminum water transfer is an important link and step in aluminum alloy casting production. The long-term use of the transfer bag has many aluminum oxides, which are hard and difficult to clean, resulting in a lot of impurities in the molten aluminum, and the quality of the cast products is at great risk; the cover of the transfer bag is frequently opened and closed, which is easy to be damaged, which affects the molten aluminum. Heat preservation and production safety; the bulky transfer bag has better heat preservation performance, but it reduces the amount of aluminum loaded and requires high tonnage of the transport forklift, which is not conducive to on-site production; there is an urgent need for an improved aluminum water transfer bag based on the above problems. Ensure production safety. SUMMARY OF THE INVENTION [0003] ...

AI Technical Summary

Problems solved by technology

The aluminum oxide in the long-term used transfer bag is too much and hard to clean, resulting in more impurities in the aluminum water, and there is a greater risk in the quality of the cast product; the lid of the transfer bag is frequently opened and closed and easily damaged, which affects the aluminum water. Insulation and production safety; the bulky transfer bag has better thermal insulation performance, but reduces the amount of aluminum loaded, and has high requirements for the tonnage of the transport forklift, which is not conducive to on-site production; there is an urgent need for an improved aluminum water transfer bag based on the above problems, improving the process and Ensure production safety
