Fault diagnosis of the hydraulic oscillation system of thin slab caster at Tangshan Steel;

The present paper analysed process and casting condition of low carbon steel for thin slab caster of Bengang.

To increase further more the output of thin slab caster, we reformed it: increasing the thickness of tap hole of mold,adopting liquid-core reduction technique of third generation and mold non-sinusoidal vibration technique.

The causes of breakout during the production of low carbon steel for cold rolling by Tanggang FTSC thin slab caster were analysed and the optimization countermeasures such as the control of mould taper,the copper plate shape of mould narrow side and SEN shape were put forward.

Optimization situations of thin slab continuous caster technique parameters in Benga- ng Steelmaking Plant after FTSC technology introduced from Danieli are described in detail,including mould vibration parameters,starting-up technique,water distribution technique for secondary cool- ing zone and so on.
