- A Novel Investigation of Initial Solidified Shell Thickness of Continuously Cast Slab Based on Solidification Structure
Yi Feng, Weiling Wang, Qi He, Sen Luo and Miaoyong Zhu
Article first published online: 12 OCT 2015 | DOI: 10.1002/srin.201500242
Shell thickness is often used to represent the growth behavior of the initial solidified shell. The present study explores the appropriate etchant to reveal the microstructure of the breakout shell at different positions along the casting direction and investigates the shell thickness based on the solidification structure of the breakout shell before and after the breakout happens. The shell thickness as well as solidification coefficient of a specific sample is obtained.

The pig iron heat with high silicon content must be treated with a specific double-deslagging. The high value of this element happens sometimes during the normal production campaign of a blast furnace. The tested new procedure allows to obtain high-quality steel with only one deslagging, saving time and consequently reducing costs.
- Effect of Long-Term Thermal Aging on Microstructure and High-Temperature Strength of a 10% Cr Martensite Ferritic Steel
Tao Gu, Mingjia Wang, Yuantao Xu, Xuan Zhou, Hongchang Zhao and Lei Chen
Article first published online: 8 OCT 2015 | DOI: 10.1002/srin.201500194
Microstructure evolution of 10% Cr steel during long-term thermal aging is shown. And the effect of aging temperature on microstructure is studied in detail. Moreover, the correlation between microstructure and high temperature strength has been established.
- The Effect of Cleanliness and Micro Hardness on the Machinability of Carburizing Steel Grades Suitable for Automotive Applications
Niclas Ånmark, Simon Lövquist, Manouchehr Vosough and Thomas Björk
Article first published online: 8 OCT 2015 | DOI: 10.1002/srin.201500243
The focus of this paper is on the effect of steels cleanliness and micro hardness on the cutting tool life, chip breakability, and resistance to abrasive wear of similar carburizing steel grades in soft part turning.
- Non-Isothermal Crystallization Kinetics of Mold Fluxes Containing Li2O for High Aluminum Steel Casting
Changlin Yang, Guanghua Wen and Ping Tang
Article first published online: 7 OCT 2015 | DOI: 10.1002/srin.201500258
Non-isothermal crystallization kinetics of mold fluxes containing Li2O are investigated in this paper. The effect of Li2O on kinetic parameters is studied to optimize the crystallization behavior of CaO-SiO2 based mold fluxes used in continuous casting of high Al steel. Furthermore, mold fluxes with no Na2O and high Li2O may help improve the lubrication effect of mold fluxes.
