Description

Technical Field

[0001] The utility model relates to the technical field of drainage sand processing, in particular to a chromium drainage sand baking device. Background Art

[0002] During the continuous casting production process, the self-opening rate of the ladle nozzle directly affects the production rhythm and protection of casting. If the molten steel in the ladle cannot flow out smoothly and the method of burning oxygen is adopted, it will cause secondary oxidation of the molten steel and reduce the quality of the molten steel. In order to improve the continuous casting effect during continuous casting, the ladle is required to be able to start pouring automatically. The use of drainage sand can effectively increase the automatic pouring rate of the ladle. It is one of the key measures to protect casting and plays a greater role in stabilizing the quality of steel. Existing drainage sand is generally composed of chromium ore sand, quartz sand, carbon black and additives. It needs to be stirred evenly during the preparation process. The existing technology generally uses direct dry stirring or stirring with water. Due to the different and large differences in the specific gravity of the materials used, it is difficult to stir evenly by dry method and there is a lot of dust. The drainage sand after adding water and stirring must be baked and dried. If the moisture in the drainage sand is not completely dried or the drainage sand becomes damp due to large temperature changes during on-site storage, when the drainage sand is put into the sliding water outlet of the hot ladle, the instantaneous high temperature will cause the drainage sand to stick together and clump, losing its lubricating effect, thereby affecting the self-opening rate of the ladle.

[0003] For example, the drainage sand baking device disclosed in publication number CN215983835U includes a silo, a discharge port at the bottom of the silo, a heat circulation tube arranged in the silo, the heat circulation tube coiled in the silo, the elbow weld of the heat circulation tube passing through the silo wall and arranged outside the silo, and steam is introduced into the heat circulation tube. The utility model has a reasonable and ingenious structural design. The saturated steam generated by the converter vaporization system is introduced into the heat circulation tube. After the drainage sand in the silo is baked by the heat of the steam, the drainage sand is directly fed into the slide of the ladle water nozzle from the discharge port without the need for secondary transportation. The elbow weld of the heat circulation tube is arranged outside the silo, which prevents steam leakage and moisture in the drainage sand. The steam generated during the production process is fully utilized, thereby reducing energy consumption and lowering production costs.

[0004] The above technical solution has some problems in practical application. When baking the drainage sand, the baking efficiency of the technical solution is easily affected by the accumulation amount of the drainage sand, and it is difficult to ensure the uniformity of baking the drainage sand.

[0005] Therefore, it is necessary to invent a chromium drainage sand baking device to solve the above problems. Utility Model Content
