Water Quenched Steel Slag

Slag Cement Questions

Slag cement is the hydraulic cement that results when molton slag from an iron blast furnace is rapidly quenched with water dried and ground to a fine powder The rapid quenching ("granulation") "freezes" slag cement in a glassy state and imparts cementitious properties to the product when ground finely

Oil Quenching Vs Water Quenching An In

Water quenching is most required for steel quenching as this material is quenched in a unique way than most other materials and metals When carboned steels are heated for quenching they are heated beyond their recrystallizing heat and very close to their melting point and at this point without rapid cooling the steel will melt where water quenching comes in with instant cooling for the steel
