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 |
