Abstract

The invention discloses a device for dynamically and continuously preparing a high-temperature superconductivity belt material by a non-fluorine chemical solution sedimentation method, which mainly comprises a continuous coating device (4), a continuous drying device (6), a continuous heat treatment furnace (9), a rolling device (1) and an unrolling device (10). The device is characterized in that the rolling device (1) and the unrolling device (10) are driven by a servo motor; a guiding wheel (5) of a belt material (3) is arranged below a slit die outlet (17) in the continuously coating device (4), and a guiding wheel (3) of the belt material (3) is arranged behind the continuous drying device (6). In the invention, the continuous motion of the belt material among the continuous coating device, the continuous drying device and the continuous heat treatment device can be realized, so that the purpose of dynamically and continuously producing the belt material is achieved. Due to the device, the production process can be conducted under non-vacuum condition, and a fluorine exhausting device is not needed, the cost is low, and the process is simple, so that the device is suitable for industrial production.

Description

technical field [0001] The invention belongs to the field of high-temperature superconducting coating material preparation, and in particular relates to a device for dynamically and continuously preparing high-temperature superconducting strips by a fluorine-free chemical solution deposition method. Background technique [0002] The second-generation high-temperature superconducting tape, that is, the coated conductor, has great application prospects in the fields of electricity, transportation, military and medicine due to its high critical current density and irreversible field in the liquid nitrogen temperature range. Among them, the high manufacturing cost is the main factor restricting the large-scale application of the second-generation high-temperature superconducting tape. At present, the buffer layer and superconducting layer of the high-performance second-generation strips in the world are generally prepared by vacuum deposition. The vacuum deposition method needs...
