melt-out
4.Synopsis: This paper present the results of primary experiment on making ductile cast iron rollers directly with blast furnace melt, It is pointed out that with proper technologies by adding moltem Cr-Fe alloy into the molten blast furnace metal and controlling the level of Cr/Si, it is possible to make ductile cast iron rollers directly with blast fur- nace melt.
5.Our country import pitch rational advanced, transport choice, serve expressway construction of our country, Other chemical product in bulk to melt to transport and probe out a road to succeed for our country even on the other hand, Play the exemplary role, therefore produce the enormous economic benefits and social benefit.
7.To analyze the influence of melt transferring condition on direct spinning FDY full package ratio. Try to find out the best process condition of melt transferring. It is regarded that polycondensation load are controlled at 150~{200 t/d},melt flow is kept above 1.45 t/h,temperature of melt is 286 ℃,temperature of Dowtherm is controlled at 280~300 ℃,and transferring press is 21 MPa.
