The surface of the slag cleaning tool is cleaned and preheated on the smelting furnace for 10 minutes. Before use, it must be heated to about 150° C. to remove the surface moisture. The slag collection box must be dry and free from flammable substances. Before cleaning the furnace, N: the flow meter value is kept at 100, the S flow meter value is adjusted to 20, the mixed gas flow meter value is maintained at 80, and after the flow is maintained for 5 minutes at this flow, slag removal can be started. Put on the protective clothing and put on the top cover and heat-resistant gloves to open the lid of the stove. Use shovels to remove the debris around the material hazards, material pots, and thermal probe protection sleeves and gather them together. Use smaller tools to keep the scum from being easily cleaned. Place it in an open area and use a larger strainer to remove the residue. Finally, use a long handled colander to clean the bottom slag. The action of slag removal is rapid. This action must be completed within 3 minutes. If it cannot be completed within 3 minutes, it must be covered with a lid to avoid excessive oxidation and combustion of the alloy fluid. Close the lid and wait for 10-15 minutes. , Open the waste collection box cover, use the colander to remove the waste residue in the waste collection box, must be completed within 3min, if you can not completely clean the slag within 3min, you can close the furnace lid, stay 10-15min and then continue to clean. At this time no foreign material or alloy material must be attached to the cover. If there is any, it must be removed before the lid is covered.
After cleaning the furnace, the surface of the furnace is cleaned, the cover of the waste collection box is closed, and the alloy material dropped on the ground is cleaned. After 15 minutes, adjust the ratio of each table is normal, the nitrogen Gay flow rate is 100, the sulfur hexafluoride GF township flow value is 7-8, and the mixed gas flow rate is 70-80. Note: If the alloy fluid begins to burn during operation, Immediately cover the furnace cover and wait for the flame to extinguish before rectifying it. When cleaning the residue, be sure not to stir the feed solution. During the operation, the turning of the feed solution should be minimized to avoid mixing the surface slag and the bottom slag into the alloy liquid; No slag can be found on the surface. When the slag is removed, it must be removed. It must be removed. Otherwise it will cause poor furnace sealing and accelerate the oxidation of the feed liquid. The magnesium alloy slag cannot be directly put into the garbage dump. The slag must be burned before Dispose of the oxidized residue in the dump, otherwise it is very dangerous.
