In order to build a conservation-minded society, it is important to conserve energy in key industries of steel, coal, nonferrous metal and power.
Attempted Energy-conserving Measures in Dust-removing System Because there is a high power-consumption in dust-removing system, engineers and technicians have been studying various methods to conserve energy.
The furnace materials need to be heated to a molten state.

Experiment Study on Fatigue Strength of Used Type Zhuan 8G (Zhuan8AG) Side Frame under the Speed Increased Condition Wang Honga, Shang Yuejin, LIU Wanxuan School of Mechatronic Engineering, Lanzhou Jiaotong University, Lanzhou 730070, China awh@mail.lzjtu.cn Keywords: side frame; fatigue strength; test study; speed increase; type zhuan 8G(zhuan 8AG) Abstract.
And statistics by casting materials, the zhuan 8A bogie side frame of ZG230-450 material and B grade steel is 12 pieces and 2 pieces respectively, the zhuan 8G bogie side frame of B grade steel is 2 pieces.
Obviously, these defects form stress concentration and become to the key factors affected the fatigue life of side frame.
