High Temperature Softening and Melting Interactions Between Newman Blend Lump and Sinter
نویسندگان
چکیده
In this work, the softening and melting (S&M) behaviour whole blast furnace (BF) performance of Newman Blend Lump (NBLL), plant sinter, sinter-NBLL mixture were studied using S&M under load test numerical BF modelling. Both physical chemical interactions between sinter lump confirmed in process. Significant improvements found because interaction. The interaction was examined X-ray/Neutron Computed Tomography (CT) scanning on samples from interrupted tests. void fraction ferrous layer to be similar higher than that for NBLL. investigated by analysing Ca transfer NBLL, which indicated started around 1200°C FactSage used assist interpretation results. It NBLL sample starts melt at a lower temperature compared other burdens present study, also agreed well with CT scan different experimental results as inputs. behaved more like NBLL; only burden same total basicity, combination formed permeable CZ, had pressure drop, gas utilization rate.

15 صفحه اولDetermination of melting temperature and temperature melting range for DNA with multi-peak differential melting curves.
Many factors that change the temperature position and interval of the DNA helix-coil transition often also alter the shape of multi-peak differential melting curves (DMCs). For DNAs with a multi-peak DMC, there is no agreement on the most useful definition for the melting temperature, Tm, and temperature melting width, ΔT, of the entire DNA transition. Changes in Tm and ΔT can reflect unstable ...
متن کاملTensile strain-induced softening of iron at high temperature.
In weakly ferromagnetic materials, already small changes in the atomic configuration triggered by temperature or chemistry can alter the magnetic interactions responsible for the non-random atomic-spin orientation. Different magnetic states, in turn, can give rise to substantially different macroscopic properties. A classical example is iron, which exhibits a great variety of properties as one ...
