Abstract: The present invention relates to a method for producing hot rolled strip steel, especially the producing method of hot rolled strip steel with multiple target thicknesses in the longitudinal direction. It is a method to produce the strip steel with different target thicknesses in the longitudinal direction by using a hot continuous rolling mill. In this method, the first equal-thickness section of the strip steel is controlled with the conventional thickness control strategy, while other equal-thickness sections and the transition section between equal-thickness sections are controlled with the variable-thickness control strategy.

Abstract: The presented invention relates to an apparatus and process, which provides a suitable application for preparative separation of organic mixtures by flash and/or vacuum liquid chromatographic techniques. In particular when a quartz tubing is used as the body of the column and fluorescent adsorbent as packing material, the apparatus and process allows the operator to very simply and inexpensively assess the separation of a mixture of UV-active organic compounds being eluted through it by projection of a UV-light is projected on it allowing the position of the UV-active material on the fluorescent adsorbent in the column to become visible. Therefore, the degree of separation of the UV-active materials can be directly monitored through the column by user without the use of detectors, presenting real-time optimization of solute resolution during the separation process, prior to collection.
