薄鋼胚 /片連鑄(Thin Slab/Strip Casting Process)

Benefits of Thin Slab/Strip Casting Process

(1)Reduce Capital Investment by Eliminating Certain Facilities

(2)Reduce Production Time (48 days→18 days)

(3)Reduce Operation Cost

(4)Reduce Energy Consumption

Thin Slab Casting Process

• Without Reduction under Mold →50-100mm

• Reduction with Solid Core →25-35mm

• Reduction with Liquid and Solid Core →10-25mm

Compact Strip Casting (CSP) Process

• First Commercial Thin Slab Plants

• Nucor Steel at Crawfordsville in 1989

• SMS Technology

• Initially for Carbon Steel

Inline Strip Production (ISP) Process

• Mannesmann-Density Technology

• Casting-Rolling Technique

• 60mm at exit of mold

• Rolled to 40mm during Solidification
