Thin Slab Casting
In Thin Slab Casting, the steel is cast directly to slabs with a thickness between 1.2 and 2.4 in (30 and 60 mm), instead of slabs with a thickness of 4.72-11.8 in (120-300 mm). Thin slab or strip casting processes reduce the steel rolling energy needs significantly. This technology enables faster production of thin products. It results in considerable savings in capital cost outlay, completion and delivery times and energy costs.

Energy Savings Potential |
Energy savings are in range of 1 – 2 GJ of Primary Energy/t of product. Saving potential is 0.3-0.4 EJ/yr if this technology is applied to quarter of world production. |
CO2 Emission Reduction Potential |
Estimated CO2 emissions savings are 20 - 40 Mt/yr. |
Costs |
Retrofit capital cost is $234.9/tonne hot rolled steel. |
