CISDI tech turns Hanye Special Steel’s ultra-thick slab caster into a world leader

CISDI-developed technology has successfully upgraded the ultra-thick slab caster 3 at Hanye Special Steel, making production safer, cheaper and more stable.

Hanye Special Steel operates under the Henan Longcheng Group.

The company’s ultra-thick slab caster first went into use in 2011. It produced length specifications ranging from 1,700mm-2,700mm and thicknesses of 250mm, 300mm, 350mm and 400mm. However, the downstream rolling production needed an online width adjustment function adding.

CISDI supplied the new function, an online width adjustment function for the mould, as a package product.

The function is now working successfully and the slab caster’s operational safety, stability, flexibility, high velocity and control abilities are now among the best in the world. 

The slab produced is particularly thick at 300 millimetres, and wide and narrow adjustments can now be made online.

This technology is based on an envelope-width adjustment model and integrated multi-disciplinary expertise.

Its development heralds a new era for more efficient slab casting.

The same CISDI technology has been performing well for common casters at Baosteel Xinjiang’s Bayi Steel, Baosteel Zhanjiang and also at Shagang.

The three plants have reported great improvements in caster availability and yield. Hanye’s reference is a first for ultra-thick slab casters.
