By DHL/TNT/FedEx express, air freight etc.Delivery & Service:Timely delivery each time. Provide reliable service and responsible for each ? customer with each product. Our target is to satisfy every customer with the? best service.(II) Control of hydrogen content in aluminum alloy smelting?Hydrogen absorption in aluminum alloy smelting is a major problem that causes pinholes in aluminum alloy castings to reduce pinhole properties and mechanical properties. Therefore, various measures must be taken to strictly control the content of hydrogen and other gases. The measures for controlling the hydrogen content in the smelting process are shown in Table 5-84. The rapid determination method of hydrogen content is shown in Table 5-85.Control key pointsDetecting one side flying EBefore charging the furnace, it is necessary to strictly remove the rust and oil on the surface of the charge, and preheat it to the specified process.TemperatureBefore adding the charge, the oven should be used to remove the moisture of the furnace (the vortex) to avoid moisture andFurnace gas hydrocarbons are in contact with the charge. For die castings that require very tight pinholes, they can be used for furnace gas analysis or for measuring wet B of air.Inert gas or cover agent to protect the liquid surface, prevent inhalation, and use enhanced degassing?Refining agent refining alloy liquidThe tool should be fully preheated to remove moisture before contact with the alloy solution.Smelting process Controls the melting temperature and time, prevents the alloy liquid from overheating, and selects and makes rapid hydrogen measurement in front of the furnace.With the refining agent and its amount and refining time, the refining agent must be fully dried before use.Smelting operation As far as possible, no damage or less damage to the protective film on the surface of the alloy and prevention of oxide scalesHuman alloy liquidCasting operation Reduce the stirring of the alloy liquid as much as possible, prevent the oxide roll from being in the alloy liquid, strictly check the process and measure the hydrogen before the furnace.1.
