Ensuring Optimal Performance in Aluminum Casting with Ideal Ratio of Titanium, Magnesium, and Aluminum

The performance of furnace slag has a significant impact on blast furnace production and product quality. The properties of furnace slag are closely related to its chemical composition. Titanium, magnesium, and aluminum are common elements found in slag, and changes in their mass fractions can significantly affect slag viscosity, melting temperature, and desulfurization.
Researchers conducted a study based on existing slag from Chenggang. They examined the effects of titanium, magnesium, and aluminum on the viscosity, melting temperature, and desulfurization of the slag. The results suggest that in the CaO-Al2O3-SiO2-MgO-TiO2 hv ternary slag system, the effects of titanium, magnesium, and aluminum on slag performance are significant.
As the mass fraction of MgO increases, the melting temperature initially decreases and then increases, the viscosity shows a decreasing trend, and the desulfurization capacity initially increases and then decreases. With the increase in the mass fraction of Al2O3, the melting temperature first decreases and then increases, the viscosity changes are complex, and the desulfurization capacity decreases. With the increase in the mass fraction of TiO2, the melting temperature and viscosity show an increasing trend, whereas the desulfurization capacity declines.
When the slag alkalinity is 1.12, the slag’s appropriate constituents are approximately 13.95% for the MgO mass fraction, about 13.75% for the Al2O3 mass fraction, and the TiO2 mass fraction should be controlled below 10.57%. Reasonably controlling the ratio of titanium, magnesium, and aluminum in the slag can improve slag performance, which has significant implications for improving blast furnace production.
At NingBo Winner Tiger Machinery Co., Ltd, we take these factors into careful consideration in our casting process to ensure we consistently deliver high-quality aluminum castings.

Impact of Aluminum Content on Microstructure and Impact Properties of Heat-Resistant Steel

Ultra-supercritical power generation technology is a primary development direction for China’s thermal power units. This evolution imposes more stringent requirements on the high-temperature strength and anti-oxidation corrosion resistance of unit materials. ZG1Cr10NiAlMoVNbN is a newly developed ferritic heat-resistant steel. The addition of aluminum can improve the material’s oxidation resistance, high-temperature strength, coking resistance, and carbon penetration resistance.
Researchers used the Thermo-Calc thermodynamic software in conjunction with experiments to simulate and analyze the balanced phases and non-equilibrium solidification process of ZG1Cr10NiAl-MoVNbN heat-resistant steel with three different aluminum mass fractions between 200-1600℃, studied the microstructure of the three experimental steel, and carried out impact tests.
The results showed that at 1050℃, the balanced phase of the experimental steel with an aluminum mass fraction of 0.10% is single γ; the balanced phase of the experimental steel with an aluminum mass fraction of 0.91% is γ phase + δ ferrite phase; the balanced phase of the experimental steel with an aluminum mass fraction of 3.67% is a single δ ferrite. The simulated results are relatively consistent with the experimental results. Meanwhile, as the mass fraction of aluminum in the steel increases, the impact power decreases significantly, and the fracture mode of the impact specimen changes from dimple fracture to cleavage fracture.
At NingBo Winner Tiger Machinery Co., Ltd, we understand these nuanced elements of Aluminum casting and leverage our expertise to ensure the quality of our products. Feel free to contact us for your specific casting needs.

Three Key Measures to Overcome Surface Cracks in Aluminum Castings

In production and daily life, surface cracks in aluminum alloys are common. When confronted with this issue, attention should be paid to three main aspects: the control of the alloy variety’s chemical composition, the casting process of the alloy variety, and operational skills along with natural conditions.
1. Crucible:
The crystallizer of aluminum alloys, also known as a condensing slot, plays a decisive role in casting. The changes in the taper of the aluminum alloy crystallizer are significant for casting. Too large a taper of the crystallizer when casting slabs increases the segregation nodules on the surface of the slab, eventually leading to surface cracks if not handled well. If the crystallizer is too narrow, surface cracks will also appear during slab casting. A good casting master would adjust the size of the crystallizer in real-time to prevent the creation of surface cracks in the slab during casting.
2. Cooling Water:
Another key factor to consider for aluminum alloy ingot surface cracks is the cooling water. The uniformity of cooling water distribution, the water pressure, the temperature can all have a substantial impact on the solid-liquid region.
3. Alloy Composition:
In essence, surface cracks in aluminum alloy ingots are one of the common defects in casting. All eight analysis reasons should be taken into account during casting. A mistake in any detail can lead to loss and waste. The control of alloy composition, impurities, and the setting of the process need to be studied and analyzed based on different environments to make accurate judgments.
For instance, the phenomena of dendritic crystal, columnar crystal, vertical dendrite, and bright crystal column all need to be prevented during casting, whether semi-continuous or fully automatic.
At NingBo Winner Tiger Machinery Co., Ltd, every element of aluminum casting is meticulously managed to prevent defects such as surface cracks. Feel free to contact us to explore how we can assist with your aluminum casting needs.
