  • It is of great importance to decrease sheet break at the size press to enhance the runnability of today's high speed paper machines. To achieve this purpose it is required to control the penetration of the starch solutions at the size press. Use of ASA sizing system provides diverse advantages in improving machine runnability since it allows us to get rapid sizing development at the size press. Domestic paper industries, however, has not enjoyed these benefits of ASA sizing system mainly because of the poor efficiency of domestic corn starches used for ASA emulsification. To improve the emulsion stability and ASA sizing efficiency, it has been pointed out that new cationic starches are needed. In this study two methods of starch modifications, i.e. esterfication of cationic corn starch with OSA (Octenyl Succinic Anhydride), and acid hydrolysis by sulfuric acid were employed as methods to improve ASA sizing efficiency. The effect of these modification was compared with conventional cationic starches.

  • Extensive width reduction of slabs is an important technology to achieve continuous production between the steelmaking and hot rolling processes. Conventionally, a vertical roll process has been used to achieve extensive width reduction. However, it is impossible to avoid the defects such as dog-bone, fish tail and camber. The deformation behavior in the width sizing process is more favorable than that in conventional vertical rolling edger, i.e. the material better flows toward the center of slab. This study is carried out to investigate the deformation of slab by two-step sizing press. The FE-simulation is utilized to predict plastic deformation mode in compression by a sizing press of slabs far hot rolling. In this paper, the various causes of the asymmetrical rolling phenomena are mentioned for the purpose of understanding of rolling conditions. Analytical results of slab-deformation by sizing press are presented below in this study.

  • Causticizing calcium carbonate (CCC) is produced as a by-product in the causticization step of the kraft pulping process. It is often calcined in a rotary lime kiln after being dewatered and reused in the causticizing process. But for the China mill, the conventional recycled way is difficult because the CCC is mainly obtained from non-wood pulping materials, which higher silicon content led to serious silicon obstacle. So it is often discarded as solid waste or used in landfill after dewatering and secondary pollution is brought. In order to prevent its secondary pollution, recent years, the CCC is used as a filler in China papermaking industry. In mill trials, the CCC can be used to replace an amount of precipitated calcium carbonate (PCC). Unfortunately, the application scope and dosage of CCC have been limited due to its lower sizing efficiency than PCC. In this study, the reason for the lower sizing efficiency of alkyl ketene dimer (AKD) when CCC was used as a filler was investigated. The results showed that the materials in green liquid, such as insoluble matter in green liquid, silicon and metal ions, were a little influence on the sizing efficiency of AKD. The higher BET and BJH pore volume of the CCC were the main reason for lower sizing efficiency of AKD when it was used as filler.
