Disposal method after bleed-out of slab continuous casting machine

The invention provides a treatment method after bleed-out of a slab continuous casting machine. The handling method comprises the following steps that when bleed-out information is received, an accident mode is started; completely canceling the soft reduction mode of the driving roller, and returning to the non-reduction mode; the accident water quantity and the accident pulling speed of the fan-shaped section are adjusted in three time periods from starting of the accident mode to finishing of throwing; wherein the first stage is within t/2, the second stage is t/2-t, and the third stage is t-finishing of throwing; the accident pulling speed V is equal to (0.50-0.70) * V0 *, and V0 is the normal pulling speed before the accident; after the accident blank is completely pulled out, the accident mode is quitted, and the normal state is recovered. According to the disposal method, it is guaranteed that the water distribution process in the accident period can completely guarantee the casting blank quality, so th
