The degassing box is made of high-strength castable through integral casting and sintering, with good thermal shock resistance.
The degassing box is made of high-strength castable through integral casting and sintering, with good thermal shock resistance.
The insulation layer is made of nano-plates and light fiber board, which has good thermal insulation performance.
The cover is integrally cast and sintered with light castable.
The working principle:to blow a certain amount of Ar-Cl2 or N2-Cl2, pure Ar, N2 into molten aluminium bottom through a high-speed rotating rotor and fully chop it by an impeller to form dispersed bubbles, so that molten aluminium is fully contacted with the pure Ar or N2. According to the principle of air pressure difference and surface adsorption, bubbles can adsorb hydrogen and oxidize slag when rising, bringing out the surface to form scum, and hydrogen is discharged. It is widely used in aluminum and aluminum alloy casting.
| Heating mode | Immersion heating | Temperature control mode | PLC automatic control |
| Average temperature of degassing box shell | ≤60℃ | Temperature of molten aluminium in degassing box | 700-770℃ |
| Static heating capacity | 20℃/hr | Static temperature control accuracy | ±2℃ |
| Thermal insulation capacity | It can maintain the temperature of the molten aluminum after the casting interval | Speed adjustment range of rotating nozzle | 0-600rpm (variable frequency and adjustable) |
| Degassing effect | Under the conditions that the metal flow rate is not greater than the maximum treatment capacity, the melt temperature of the molten aluminium is between 700℃ and 770℃, and high-pure N2(≥99.996%) is used (excluding high magnesium alloy): hydrogen content before ≤0.30ml/100gAl, hydrogen content after ≤0.12ml/100gAl hydrogen content >0.30ml/100gAl,degassing efficiency ≥60％ | ||
The degassing box is made of high-strength castable through integral casting and sintering, with good thermal shock resistance.
Tubular filtration equipment is installed between CFF filtration equipment and rolling mill.
The filter box lining is made of qualified castable and produced under sintering. It has high temperature resistance, corrosion resistance and good thermal insulation.
Caster tips have the advantages of uniform molten aluminium flow, laminar flow, no blockage, and the same temperature in the caster tip outlet.
