faces. Wear occurs in regions of the mold where the air gap THE thin-slab mold for continuous casting of steel is is fully closed. Won et al.,[2] using a two-dimensional (2-D) prone to surface crack formation, particularly in funnelcoupled thermo-elasto-plastic finite-element model of conshaped molds. This is likely associated with the higher castventional(More)
Three-dimensional (3-D) finite-element thermal-stress models have been developed to predict temperature, distortion, and residual stress in the mold of continuous casters of thin steel slabs, comparing both funnel-shaped and parallel molds. The mold shape and high casting speed leads to higher mold temperatures and shorter mold life than in conventional(More)
We present the online coupling of a free-flow isotachophoresis (FFITP) device to an electrospray ionization mass spectrometer (ESI-MS) for continuous analysis without extensive sample preparation. Free-flow-electrophoresis techniques are used for continuous electrophoretic separations using an electric field applied perpendicular to the buffer and sample(More)
Two decades of operating experience have shown that reducing the corner radius from 12–16 mm to 3 or 4 mm A finite element thermal stress model to compute is beneficial in reducing longitudinal corner cracking.4 In the thermomechanical state of the solidifying shell addition to lessening crack frequency, decreasing the corner during continuous casting of(More)
