A mold transfer assembly includes a transfer housing providing an interior defined by one or more sidewalls and a top. The transfer housing is sized to receive and encapsulate a mold as the mold is moved between a furnace and a thermal heat sink. An arm is coupled to the transfer housing to move the transfer housing and the mold encapsulated within the transfer housing between the furnace and a thermal heat sink. The transfer housing exhibits one or more thermal properties to control a thermal profile of the mold.

The present disclosure relates to a wear part having high wear resistance and strength and a method of making the same. The wear part is composed of a compound body of cemented carbide particles cast with a low-carbon steel alloy. The low-carbon steel alloy has a carbon content corresponding to a carbon equivalent Ceq=wt % C+0.3(wt % Si+wt % P) of about 0.1 to about 1.5 weight %. The wear part could include a body with a plurality of inserts of cemented carbide particles cast into a low-carbon steel alloy disposed in the body. Each of the plurality of cemented carbide inserts are coated with at least one layer of oxidation protection/chemical resistant material. The plurality of inserts are directly fixed onto a mold corresponding to the shape of the wear part. The cemented carbide inserts are then encapsulated with the molten low-carbon steel alloy to cast the cemented carbide inserts with the low-carbon steel alloy.
