Characterization of the products obtained by pyrolysis

2019-11-1  Magnetic separation of steel slag. During the integration process of oil sludge pyrolysis with steel slag reduction, the yield of pyrolysis tar reached a maximum of 10.63% at 550 °C. So, the magnetic separation of steel slag was investigated at 550 °C. As is well known, steel slag had a poor reduction effect at low temperatures.

Characterization of the products obtained by pyrolysis

The recovered steel slag concentrate was measured by a magnetic separation method. The results indicated that steel slag addition caused the weight loss rate of oil sludge to increase. The yield of tar reached a maximum of 10.63% at 550 °C, and the increase in temperature intensified the secondary thermal cracking of the volatile fraction and decreased the tar yield.

Structure characterization and grinding performance

2020-7-16  Figure 6 shows the hysteresis loop of the gas-quenched steel slag abrasive measured in the magnetic field strength range from − 1 to 1 T at 27 °C. The loop reflects the magnetization of the gas-quenched steel slag abrasive under an external magnetic field. This phenomenon is an important feature of the magnetic material.

The Characterization of Steel Slag by Alkali Activation

Result obtained shows that alkali-activated steel slag had better water absorption than 50/50 Fe/SS alkali-activated slag at 7 days curing. Furthermore, the activation of steel slag was contributed to the presences of gehlenite, larnite, akermanite and magnetite. Lastly, the alkali-activated steel slag presents the vibration of the Si-O bonds at wave number 970.46 cm﹣1 contributed by the calcium silicate
