Abstract: Based on the BECMP production line, this article introduced the main technological process for the production of BECMP pulp using aspen branch wood as the raw material. For better understanding of the new pulping method, Compared with the widely applied production line of P-RC APMP, the relevant pulping performances and operational efficiencies of BECMP were evaluated. The results showed that: using aspen branch wood in BECMP pulping was technically feasible, and it had more benefits as effective use of the lignocellulose raw material, energy saving, and reduction in water consumption. Most notably, the properties of the pulp met the requirements of APMP-based pulp mills, and simultaneously, its tensile strength was better than that of the APMP pulp.

Abstract: Incremental Sheet Forming (ISF) is an emerging process. As a sheet metal forming process, it allows manufacturing components without the development of complex tools in comparison with stamping process. Although existing technical research achievements are plenty, it remains to be improved to make an industrially suitable process. This work is dedicated to the incremental forming of the throttle pedal fixed plate to analyze and figure out the reasonable practical procedure of ISF process, and helpful to promote the industrial applications of ISF.

Abstract: D-Tagatose is a ketohexose monosaccharide and recognized as a low-calorie substitute sweetener that could be used in nonchronic drugs, foods, beverages and dietary supplements. Currently, the biological production of D-tagatose using L-arabinose isomerase has caused extensive attention. In the article, properties and recent researches about D-tagatose and L-arabinose isomerase are described. The industrial application and existing problems are also stated.

Abstract: The paper presents a possible practical application based on two 6R overconstrained mechanism, more precisely 6R Wohlhart overconstrained mechanism. Two of these mechanisms are put in a mirror position, in order to obtain a car jack. The mechanisms are disposed in other position than the original one, three non-adjacent joints being constrained to remain in a fixed plane.

Abstract: The distortion and the residual stress are the inevitable consequences of the welding and these may reduce the strength and the quality of the welded structures. To prevent the harmful influence of the welding distortion and the residual stress, their theoretical prediction is necessary. However the existing methods are mostly developed for the study of specimens in laboratories. Compared to the specimens, the structures manufactured in the industry are larger in size and more complex in geometry. For the theoretical prediction applicable to industrial structures, more powerful and practical methods are necessary. To achieve this goal, the authors developed a fast computational method for thermal elastic plastic analysis and an elastic finite element method using inherent deformation.

Abstract: An online slab quality diagnosis & analysis system named CISDI_SQDS ONLINE R2011 has been presented in this paper. The system is based on mechanism of defects, which mainly refer to surface crack & internal crack, heat-transfer & solidification simulation, stress & strain calculation and metallurgical process analysis about continuous casting. Combining with BP neural network, several kinds of quality loss factors are used to describe the possibility of inducement. Meanwhile, the respective crack formation indexes are introduced to be the theoretical reference data for slab quality level evaluation and guiding production. The CISDI_SQDS ONLINE R2011 system was firstly applied on the No.1 Slab Continuous Caster of Bayi Steel in China. It is preliminary proved that the model is reliable and reasonable. It can be widely used as an important theoretical tool for prediction & control for slab quality in continuous casting process.

Abstract: To increase the efficiency of float valve tray in plate column, a combined directed valve tray was developed. Comparative analysis of tray pressure drops, entrainments, weeping rates and mass transfers was conducted between the widely used V1-type float valve trays and the combined directed valve tray. The applications of the combined directed valve tray in atmospheric pressure device, catalytic cracking unit and gas fractionation device were also listed, which indicated that it was a significant improvement of float valve tray.

Abstract: A numerical model for a multiphysics problem is presented. It includes the movement of subdomains, which are embedded in a global air domain. The description of the movement is based on a discrete level set representation of the moving boundaries. It is based on the original geometry of the moving tools, such that the mesh quality is not reduced in subsequent time steps.

Abstract: The Pb–Ag–Ca alloy anode with surface passivation was applied in industrial production of zinc electrowinning. The application situation was investigated by detection and tracking more than 3 months. The results were analyzed by comparison with the data acquired from the production using the reference anodes without surface treatment. The results showed that using the anode with surface passivation can increase zinc yield, reduce Pb content in zinc product, prolong the anode life by improving the corrosion resistance, and then reduce the production costs.
