Anti-gravity casting concept and types of small make up in the last article has been explained, their purpose, in order to make everybody can have preliminary knowledge and understanding to its, can have a basic concept, so as to better for other content and learning. So today, in order to let everybody to know more about anti-gravity casting, below small make up will continue to explain some of its knowledge content, mainly concentrated in the casting process parameters which on the one hand, introduce the types and how to determine the process parameters. So, hope everybody can good good study, let oneself learned to more and more widely.
Types of anti-gravity casting technological parameters, and how to determine, below will be conducted according to the different parameters, the main are:
(1) lift pipe diameter
To determine process is: consider filling time and velocity, and then to determine the lift tube flow requirements. After sure, its diameter can be calculated. Its material is determined by the types of alloy and casting quality requirements.
(2) the filling pressure
Liquid metal filling pressure, it means the time it takes to fill the cavity, it is with the casting shape size, shape and quantity of metal melting crucible and so on. Once the casting pouring quantity to determine the good, the filling pressure can be calculated.
(3) the holding time
Is from liquid to liquid metal solidification in full the amount of time, it is basically a casting solidification time required, it is with the casting wall thickness, the type of alloy solidification and crystallization pressure, generally is congealed crystallization pressure, the greater the shorter the holding time.
