On May 23, 2019, we received a project of slag tank from a South American customer. According to the customer's requirements, it is an important equipment for steelmaking in the metallurgical industry. It is a kind of container for holding hot slag generated in the process of steel smelting, and it has bowl-shaped container with lifting lugs on both sides.
At that time, the South American customer required that the slag tank could hold lead liquid at 900℃ and was made of pearlitic ductile iron, so we recommended qt500-7 ductile iron for him. Qt500-7 is of medium strength and toughness, and has certain resistance to rapid temperature change and corrosion resistance, and adopts sand casting process. Sand casting is a process with a long history and wide application.

Chemical Component of QT500-7:

Composition(%) C Si Mn S P Mg Re
QT500-7 3.40-3.90 2.00-2.90 ≤0.60 ≤0.05 ≤0.03 ≤0.10 ≤0.10

 

 

 

 

Mechanical Capacity of QT500-7:

Tensile Strength MPa ≥500
Yield Strength MPa ≥320
Elongation % ≥7
Hardness HB 170~230HB
Basal Body Ferrite + pearlite

We sent our Suggestions to the customer. Through communication, the customer asked us to improve the performance of the product, so we finally chose the material qt600-3 and did the annealing treatment. The material is pearlitic ductile iron.

Chemical Component of QT600-3:

Composition(%) C Si Mn S P Mg
QT600-3 3.6~3.8 2.4~2.8 0.3~0.5 0.03~0.035 ≤0.1 0.045~0.05

 

 

 

Mechanical Capacity of QT600-3:

Tensile Strength MPa ≥600
Yield Strength MPa ≥370
Elongation % ≥3
Hardness HB 190~270HB
Basal Body Ferrite + pearlite
