I. Brief Introduction
No cover ladle, also called No cover ladle, is a common tool for casting aluminum water in melting and casting workshop. The water transport of aluminum casting, so also known as the aluminum water bag.
Ⅱ, Product Structure
The whole structure of the open lifting ladle is relatively simple, and the cover cover and vacuum extraction equipment are removed, including column, crossbeam, transmission mechanism (handwheel, motor, turbine, reducer, etc.), package, trunnion, etc. compared with the vacuum lifting bag.
Ⅲ, The Use Process
When the aluminum water is turned upside down, the no cover ladle( also have vacuum ladle) is transported to the casting workshop, and the package is inclined to 15 degrees ~30 degrees to control the flow velocity so as to avoid the aluminum water overflowing the mold.
Ⅳ, Lining Material
1, because the opening ladle (No cover ladle) is shipped high temperature liquid aluminum, the ladle lining lining needs to build refractory materials, in order to protect the steel structure of the package is not melted corrosion, but also play a heat preservation effect, so as to avoid the rapid solidification of aluminum liquid.
2. Refractory materials are divided into firebrick masonry and castable masonry. The bricks are laid at the bottom of the bricks, and then a half layer is first laid, then a standard firebrick is laid, and the walls are covered with an arc refractory brick.
Ⅴ, Transmission Mechanism
The transmission of the lifting ladle is the same as that of the vacuum lifting bag. It is also divided into a manual lifting ladle and a flashlight, and the reducer is equipped with a reducer to stabilize the aluminum liquid without tilting.
