Problems solved by technology

[0004] At present, in the production of metallurgical continuous casting, the baking of refractories and the drying of mold slag are carried out in a decentralized and independent operation mode. The waste heat generated by the baking of refractories is directly discharged after cooling down, which is not fully utilized, and the drying process of mold slag requires additional There is no overall plan for heat utilization in the metallurgical continuous casting process, high energy consumption, high production costs, and an intensive production model has not yet been formed

Abstract

The invention relates to the technical field of metallurgical continuous casting, in particular to a refractory material baking crystallizer casting powder drying device and method. The refractory material baking crystallizer casting powder drying device comprises a gas collection device, a drying device and a venturi pumping device; the gas collection device is used for collecting hot gas of a baker and comprises an intermediate pipeline for conveying the hot air, and the intermediate pipeline provides a heat source for drying for the drying device; and the venturi pumping device is used forproviding pumping power of the gas collection device. The refractory material baking crystallizer casting powder drying method comprises the steps: the gas collection device collects a hot fluid, andthe hot fluid flows into a heat conducting pipe of the drying device; casting powder enters a drying chamber, and the heat fluid carried by the heat conducting pipe and the casting powder are subjected to heat exchange; and the hot fluid flows into the venturi pumping device under the pumping effect of the venturi pumping device. According to the refractory material baking crystallizer casting powder drying device and method, refractory material baking waste heat is fully utilized, energy consumption is reduced, and the equipment structure is simplified.

Description

technical field [0001] The invention relates to the technical field of metallurgical continuous casting, in particular to a drying equipment and method for mold slag of a refractory baking crystallizer. Background technique [0002] In metallurgical continuous casting production, refractory baking is a key link in the production preparation stage. With the improvement of the quality requirements for continuous casting slabs, the quality requirements for mold powder in the continuous casting process are also continuously increasing. [0003] Mold powder is placed on the molten steel surface in the mold during the continuous casting process to play the role of lubrication, heat preservation, oxidation prevention and absorption of non-metallic inclusions. Since casting with submerged nozzle and mold flux, the technology of mold flux has been improved and developed. The basic functions of mold powder are: to protect the molten steel on the meniscus of the mold from the seconda...
