This utility model discloses a sealed food storage container, including a container body, a lid that fits with the container body, and a flexible sealing ring. The lid is a downward-opening cover structure. An annular groove with the opening facing downwards is provided around the outer edge of the container body's opening. The upper part of the sealing ring is embedded in the annular groove, while the lower part of the sealing ring protrudes outside the annular groove, sealing with the inner wall of the lid when the lid is placed on the container body's opening. This sealed food storage container achieves a seal while preventing the sealing ring from contacting the food inside the container, thus effectively preventing food stains from remaining on the sealing ring and preventing contamination of the food inside the container. Therefore, frequent disassembly and cleaning of the sealing ring is unnecessary, reducing the user's maintenance burden. Furthermore, since the edge of the lid and the sealing ring are not located within the internal space of the container body, the container body can achieve a larger effective volume with the same external dimensions, fully accommodating food and improving its internal space utilization.

This invention discloses a method for rapidly adjusting the furnace conditions of a lean-burn electric arc furnace, belonging to the field of pyrometallurgical nickel smelting technology. The method includes: measuring the height of the frozen layer inside the lean-burn electric arc furnace; when the frozen layer height is greater than 650 mm, simultaneously implementing coordinated control operations to reduce the slag oxidation depth (making the converter slag magnetic iron content <25%) and increase the reducing agent addition rate of the lean-burn electric arc furnace; after adjustment, measuring again, if the frozen layer height is less than 600 mm, restoring to normal process parameters; otherwise, repeating the adjustment until the target is met. This invention establishes a rapid response and upstream-downstream coordination mechanism based on the frozen layer as a criterion, which can effectively reduce the magnetic iron content in the slag, quickly eliminate excessively thick frozen layers, significantly improve slag fluidity, and ensure the stable and efficient operation of the lean-burn electric arc furnace system.
