In the West, this is demonstrated by placing a coin on the keel block
, but in Vietnam it is achieved through generous offerings and blessings from monks.
Then there was the Coin Ceremony for MSC Grandiosa, when coins are traditionally placed under a keel block
to bless the ship and as symbol of good fortune.
Representatives from APSI and Crowley were in attendance to place the coins and sign the keel block
, said a statement from APSI.
A To provide certification that the cast iron metal and pouring process have produced castings that meet customer requirements, it is common for metalcasters to pour keel block
or "Y" block molds at prescribed intervals of the casting production cycle from which test bars can be excised.
Process: Various section sizes of cast-to-shape tensile specimen patterns were poured in keel block
molds made of green sand and in Y-block molds made of chemically bonded sand.
Lyle Jenkins, DIS technical director, added, "Levi had an instrumental influence on ductile iron production via cupola melting." Loper recalled that Levi was instrumental in the development of a modified keel block
, which produced the "Levi bars."
One test bar from the keel block
passed, but how sure are you that the other bars will pass when the customer pulls them?
