“…Further, the mass density in the reference configuration is taken as r 0 ¼ 7800 kg=m 3 . Lee et al (1999) report values for the latent heat of carbon steels ranging from À1136 to À4292 J=mol (about À20 to À77 kJ=kg) for carbon concentrations p c between 0.002 and 0.8 wt% (for transformations occurring at the A 1 temperature). Based on these data, we extrapolate the latent heat for p c ¼ 1:4 wt% as lðA 1 Þ % À113 kJ=kg, which, from Eq.…”

Acquiring the thickness of slag layer in continuous casting tundish accurately is beneficial to continous casting stably, and improves enterprise benefit. A new method to measure the thickness of slag layer in continuous casting tundish, based on temperature information is put forward in the papers. A measuring bar, made of Refractory Material, was inserted into the tundish to perceive the temperature. Then the thickness of slag layer may be obtained accurately by temperature interface between air layer and slag layer, and slag layer and molten steel layer. After applying to the slag layer thickness measurement in steel metallurgy field, it has a favorable application prospects because of the measuring error about less than 2.6mm.

A series of area temperature maps were obtained from the upper surface of a moving thermomechanical controlled processed (TMCP) microalloyed steel skelp following laminar cooling using an infrared video camera. In addition, an emissivity probe was used to obtain both the emissivity and temperature at the mid-face of the moving skelp. Properly sampled infrared camera temperature measurements correlated well with both the measured probe temperature and with the process control pyrometer. A finite element thermal model of the system, in conjunction with the transverse skelp temperature profiles obtained from the infrared camera, was used to quantify the size and shape of the laminar cooling water jet's direct impact zone on the skelp. The region experiencing direct water impact was found to be constrained by the residual water present on the moving skelp.
