Propagation form of internal cracks induced by continuous casting soft reduction and control strategy for internal quality

The propagation form of internal cracks induced by continuous casting soft reduction and the control strategy for enhancing the internal quality of 45 steel through industrial trials and a three-dimensional flow-heat transfer-solidification coupling model were investigated.The results showed that the internal cracks induced by soft reduction exhibited a characteristic of being"coarse in the middle and fine at both ends",and displayed an elliptical arc distribution on the loose side of the strand cross section.The cracks originated within the brittle temperature range and propagated inward to the liquid impenetrable temperature and outward to the zero ductility temperature or below.The control strategy for enhancing the internal quality of the 45 steel strand through soft reduction is to adjust the casting speed or the reduction zone appropriately,ensuring that the central solid fraction of the reduction zone falls within the range of 0.33-0.99.At this point,a reasonable reduction amount is allocated to eliminate the center shrinkage cavities and center segregation,even if it results in minor reduction-induced cracks.

Prediction of Newhall navel orange internal quality based on digital microscopy

The traditional technology for internal quality detection of citrus fruit is believed to be destructive,inefficient,and error-prone.To address these issues,a novel method has been developed to evaluate nondestructively the sugar-acid ratio(SAR)of soluble solids by using the oil glands density(OGD).In this study,a total of 584 samples with different widths were collected.The sample data were correlated that the SAR and OGD decreased with time during storage.The relevance with time was significant between SAR and OGD of citrus positively correlated in the calibration group(R2=0.82),which indicated that OGD could be used to predict the internal quality of citrus.It indicated that a new generation of digital microscopy could provide an alternative to predict nondestructively the internal quality of citrus fruit,as well as some theoretical insight for further studies of online quality detection in the future.

Dynamic Soft Reduction for Continuously Cast Rail Bloom

Center porosity and centerline segregation in continuously cast bloom can be minimized by the well-known method of dynamic soft reduction. Metallurgical results of soft reduction previously employed in continuous bloom casting for heavy rail steel in Panzhihua Iron and Steel Group were not fully achieved because of the improper soft reduction process. Therefore, experiments for optimizing the process parameters of soft reduction for bloom were carried out. The results show that the proportion of the center porosity, which is less than 1.0, increases from 28.41% to 99.81%, while the proportion of the centerline segregation class increases from 40.91% to 100%, and the proportion of the central cavity increases from 92.05% to 100%, whereas the center carbon segregation index decreases from 1.17 to 1.05. The internal quality and the mechanical performance of the rails produced from continuously cast blooms meet the requirement of high-speed tracks of 350 km/h.

Rapid and nondestructive detection of watercore and sugar content in Asian pear by near infrared spectroscopy for commercial trade

Watercore and sugar content are internal qualities which are impossible for exterior determi-nation.Therefore the aims of this study were to develop models for nondestructive detection of watercore and predicting sugar content in pear using Near Infrared Spectrosoopy(NIR)tech-nique.A total of 93 samples of Asian pear variety“SH-078”were used.For sugar content,spectrum of each fruit was measured in the short wavelength region(700-1100nm)in the reflection mode and the first derivative of spectra were then correlated with the sugar content in juice determined by digital refractometer.Prediction equation was performed by multiple linear regression.The result showed Standard Error of Prediction(SEP)=0.58°Bx,and Bias=0.11.The result from t-test showed that sugar content predicted by NIR was not signifcantly different from the value analyzed by refractometer at 95%confidence.For watercore disorder,NIR measurement was performed over the short wavelength range(700-850 nm)in the transmission mode.The first derivative spectra were correlated with intemnal qualities.Then principle com-ponent analysis(PCA)and partial least squares discriminant analysis(PLSDA)were used to perform discrimination models.The accuracy of the PCA model was greater than the PLSDA one.The scores from PC1 were separated into two boundaries,one predicted rejected pears with 100%classification accuracy,and the other was accepted pears with 92%accuracy.The high accuracy of sugar content determining and watercore detecting by NIR reveal the high efficiency of NIR technique for detecting other internal qualities of fruit in the future.

Annual report readability and corporate agency costs

Annual reports are the main sources of information for outside investors' investment decisions and enable shareholders to supervise the management.Difficulties with the readability of these reports may therefore have serious consequences. Using 19,221 firm-year observations of Chinese A-share listed firms from 2001 to 2015, we investigate the association between annual report readability and corporate agency costs, where readability is proxied by report file length and/or file size. We find that firms with better annual report readability experience lower agency costs, and the negative association between readability and agency costs is more pronounced in firms with higher external audit quality, internal control quality or analyst coverage. These results hold after several robustness checks. The positive effect of annual report readability is stronger in private firms than in state-owned enterprises, and becomes stronger after the implementation of new accounting standards in 2007. Readable annual reports can help in monitoring corporate insiders' opportunistic behavior and thus reduce agency costs.
