Aluminum alloy melt online purification technology refers to the refining of the aluminum alloy melt out of the furnace. The specific operation process is as follows: First, the melt is led out of the furnace, and refined gases such as chlorine mixed gas, argon and nitrogen are passed into the online refining device, and the […]

The electrolytic aluminum liquid has a high content of gas and impurities. In view of the above composition characteristics, the melt refining process must be strengthened. The refining process for aluminum usually uses refining agent and blowing with nitrogen, the quality of refining agent and nitrogen must be ensured. The production uses high-quality refining agent and […]

The aluminum alloy round bar casting platform is a tool that converts the liquid aluminum in the furnace into solid aluminum of a certain shape and specification, and is a key part of casting molding. At present, imported equipment represented by American Wagstaff has occupied the main domestic market. The hot top accessories produced by […]

After the die-casting aluminum alloy is melted and refined, the aluminum water is taken from the subcontract during the subcontracting and degassing, the time before and after the refining agent is added, the nitrogen flow of the rotating degassing aluminum, the speed of the graphite rotor, the degassing time, the diameter and height of the […]

Theoretically speaking, the purity of aluminum alloy melt should reach a high level after refining in the furnace and on-line degassing and slagging. However, the actual results are often not ideal. One of the important reasons is that the aluminum liquid passes through the launder. The slagging and gas suction conditions during the casting process. […]

At present, the online degassing of molten aluminum is more widely used for molten aluminum purification. The on-line degassing equipment produced by AdTech is installed between the furnace and the casting machine to eliminate hydrogen and other residues contained in the molten aluminum and its alloys that affect its quality and mechanical properties. The degassing […]

في الوقت الحالي، تتمثل الطريقة الشائعة الاستخدام لتنقية الأفران، والتي تتميز بفعالية جيدة في إزالة الخبث والغازات، في تمرير مادة التذويب المرشوشة التي تتكون مكوناتها الرئيسية من كلوريد الصوديوم (NaCl) وكلوريد البوتاسيوم (KCl) وفلوريد الصوديوم (NaF) وغيرها، عبر خزان تخزين مضغوط، ثم خلط النيتروجين مع مادة التذويب، ورشهما بالتساوي عبر أنبوب معدني. بعد صهر الألومنيوم. في […]

Aluminum melt quality can generally be measured by two indicators: the content of inclusions in the solid structure and the hydrogen content in the liquid melt. When smelting aluminum and aluminum alloys, it is inevitable that the melt will be polluted by hydrogen and inclusions. Their content in the aluminum melt is an important indicator […]

Mold coatings are mainly made up of water as a carrier, high temperature binder (usually water glass) and refractory materials. Coatings with different properties have different compositions. Thermal insulation coatings contain thermal insulation mineral mixed materials, such as talc, mica, diatomaceous earth, titanium dioxide, alumina and so on. Lubricating and thermally conductive coatings are usually […]

Refractory coating thermal insulation depends not only on the thickness of the coating, but also on the porosity of the coating itself. The thickness of the coating has an optimal range, experience shows that it is generally around 150m~250m. The porosity of the coating is largely affected by the application method and conditions used, because […]
