Abstract
An apparatus for preventing a steam explosion, in a water discharge channel of a secondary cooling zone of a horizontal type continuous casting machine, caused by molten metal breaking out from said cast strand, which comprises: a metal net provided substantially horizontally between said secondary cooling zone and said water discharge channel for granulating said molten metal breaking out from said cast strand; a water flashing mechanism provided over the entire width of said water discharge channel above said water discharge channel, said water flashing mechanism comprising a plurality of water injection ports ejecting water on said molten metal granulated through said metal net for rapidly cooling and solidifying said molten metal and washing away the resultant soldified granulated metal toward the downstream of said water discharge channel; a tank, provided at the downstream end of said water discharge channel for receiving the water and the granulated metal discharged from said water discharge channel and for separating said granulated metal from said water.
