Strip Casting – Castrip® Process

Castrip® is one of the strip casting technologies successfully commercialized.  The process allows the direct casting of thin strip from liquid steel, in gauges currently ranging from 0.8mm to 2.0 mm. In addition to the substantial energy savings it enables, the process is more tolerant to high residual elements without loss of quality, enabling greater flexibility in ferrous feed sourcing. Consequently, the process allows higher scrap recycling and reduces dependence on pig iron or DRI.

Strip Casting – Castrip® ProcessCosts & Benefits

Parent Process: Casting
Energy Savings Potential

Compared to thick slab casting (hot rolling, pickling and cold rolling), the Castrip® process saves approximately another  2 GJ/t.

CO2 Emission Reduction Potential

Correleating from the energy savings reported in APP (APP, 2010. p.94), the process is estimated to redcue CO2 emissions by 80-90% comparing to conventional casting.

The State–of-the-Art Clean Technologies (SOACT) for Steelmaking Handbook

 

The State–of-the-Art Clean Technologies (SOACT) for Steelmaking Handbook is developed as part of the Asia-Pacific Partnership on Clean Development and Climate program and seeks to catalog the best available technologies and practices to save energy and reduce environmental impacts in the steel industry. Its purpose is to share information about commercialized or emerging technologies and practices that are currently available to increase energy efficiency and environmental performance.
