China foundry industry powerful is a big progress in our country, in the industrial manufacturing we should joint efforts need to be better development, today to tell everyone about a cash casting technology, is the centrifugal casting, the advantages of it are explained one by one below. 1 of centrifugal casting, precision casting, the first patent is in 1809 by the British people love's child (Erchardt), and then to the early 20th century, this method is on the production side slowly begin to gradually to be adopted.In the 30 s in our country also began to use the centrifugal tube, cylinder castings such as iron, copper, cylinder liner, bimetallic steel back copper sets, etc., almost all centrifugal casting is a main method;In addition, some special steel seamless steel tubes in heat resistant steel roller blank, paper machine drying drum production side, such as precision casting of the centrifugal casting method is very effective.
