The Landing Craft Air Cushion (LCAC) is a class of air-cushioned landing craft (hovercraft) used by the United States Navy and the Japan Maritime Self-Defense Force (JMSDF). They transport weapons systems, equipment, cargo and personnel from ship to shore and across the beach. It is to be replaced in US service by the Ship-to-Shore Connector (SSC).

2011年9月1日 · The behavior of non-metallic inclusions in LCAK (low carbon aluminum killed) steel produced by BOF (basic oxygen furnace)-LF (ladle furnace) refining-FTSC (flexible thin slab continuous caster) production route was investigated.

2012年12月5日 · Efficient secondary refining process is necessary for massive and stable production of low carbon aluminum-killed (LCAK) steels. Plant trials were performed to investigate the cleanliness of steels. Characteristics of composition, cleanliness, and inclusions of LCAK steel during different secondary refining processes, including LF, CAS, RH-LIT ...
