2. Process and composition and description of homogenizing furnace group
1. Process flow Storage: The crane will hoist the modified aluminum alloy round ingot to be processed on the soaking tray of the storage platform;
Furnace loading: The three-dimensional composite loading and unloading truck starts to load the unloading pan from the storage platform, and then drives the truck to run to deliver the pan to the furnace door, and at the same time the furnace door is lifted in place, and the furnace door is securely locked; the feed truck enters the furnace, The lifting device is lowered, the tray is steadily placed on the bracket in the furnace, the charging car is withdrawn, and the furnace door is closed and reliably sealed;
Soaking: After the furnace door is closed, the soaking furnace will automatically quickly heat up and keep warm according to the set soaking process curve. During the heat preservation process, the temperature difference of each point in the furnace is ≤5℃; When the furnace gas temperature reaches the set temperature, the circulating fan can automatically switch the speed according to the process requirements to ensure the uniformity of the furnace temperature; When the furnace enters the heat preservation stage, the number of burners or fuel supply is automatically adjusted to meet the requirements of furnace temperature uniformity. Out of the furnace: After the soaking process is completed, the charging car is driven to the door of the soaking furnace, the furnace door is safely locked after it is raised in place, and the charging car enters the furnace and starts to take out the material pan and drives it to the cooling chamber;
Cooling: the material truck runs to the door of the cooling room, the door is opened, the material truck enters the cooling room, and the hot material tray is placed on the indoor material rack, the material truck exits, the door is closed, and the rapid cooling system is activated to quickly cool the aluminum alloy round ingot. When the ingot is cooled to the set temperature required by the process, the air slow cooling method is adopted, that is, the outdoor air enters the cooling chamber through the fan to cool the aluminum alloy round ingot, and the hot air is discharged by the exhaust fan;
Unloading: After the cooling of the aluminum alloy round ingots is completed, the material truck automatically enters the room to take out the material pan, waiting for unloading, after unloading, the crane will store the material and start the next cycle.
