Description
The application is a divisional application, the application number of the original application is CN202210138648.X, the application date is 2022, 2 and 15 days, and the invention name is 'heating system for preparing superconducting tapes'.
Technical Field
The invention relates to the field of superconducting materials, in particular to a heating system for preparing a superconducting tape.
Background
The description herein refers to PLD plating of a REBCO film but is not limited to REBCO, a superconducting material or PLD, a method.
In the coating process of various vacuum coating processes, in order to ensure the quality of a film on a substrate, the coated substrate needs to be heated for preparing a plurality of films, and the temperature deviation range of the substrate in the coating process has strict requirements. Therefore, the heating system is an essential part of the coating apparatus. For a continuous flexible substrate strip with a narrow and long width, a roll-to-roll structure which reciprocates in a circulating manner is usually adopted in coating, so that the coating area is increased, and the coating efficiency is improved. Although the heating systems have different structures, sizes, geometric shapes and the like in different equipment, the roll-to-roll tape-moving structure of the strip of the approximately two-dimensional flexible substrate requires that the area of the heating surface uniform-temperature area adopted by the heating system is large enough to match the increased coating area, so that the temperature of the strip in the coating process is kept unchanged. In summary, in order to ensure the coating quality of the roll-to-roll continuous strip, the heating system needs to ensure the temperature of the strip to be uniform on a large-area heating surface. On the other hand, large-scale industrial production requires a high tape speed of the flexible substrate to meet the demand for high yield thereof. The size limitation of the heating plates and the high speed of the tape transport result in a short heating time of the flexible substrate tape, and how to raise the temperature of the tape to the target temperature in a short time is a new demand for the heating system.
The deposition temperature is one of the most critical parameters in the superconducting layer process. The temperature zone for growing the ReBCO film is very narrow and is generally only 20 ℃. It is often not convenient to measure the temperature of the substrate accurately. The reason is that there is often a significant difference between the measured temperature and the actual temperature. The thermocouple is used to test the temperature of the substrate, the stability of the test depends on the stable contact between the two, and even if the contact is ideal, the bottom surface and the surface of the substrate still have a temperature gradient, which is the source of the difference.
The heating system has reached thermal equilibrium and if the base strip placed therein is static at this time, the base strip can be considered as a point in a thermal environment. At this point, the substrate is likely to reach a thermal equilibrium state due to the longer heat exchange. This differential relationship is therefore stable and it is relatively easy to determine the relative optimum deposition temperature.
Unlike static processes, in a dynamic tape-walking system, each point in the baseband experiences many different positions along the entire path. Due to the thermal gradients in the heating system, the temperature fluctuates at various points along the entire baseband path. The base band passes through the path at a certain speed and passes through different temperature areas, so that continuous heat absorption and heat release processes can be realized, and the temperature cannot be fixed all the time. If the base band is controlled to be at the optimum temperature during coating, the optimal situation is that the temperature gradient in the whole path taken by the base band is smaller, and the better. However, the larger the area of the film to be coated, the better the large area, and the larger the area, the larger the temperature gradient is easily caused, which creates a contradiction with the ideal temperature control situation.
Two of these problems are very tricky: 1. and (3) obtaining the temperature distribution of the position of the strip of the coating area through a series of temperature tests. 2. How to obtain the temperature distribution of the strip passing through the coating area again.
The first problem is difficult because of the following two reasons: 1. the thermocouple cannot be directly arranged in the coating area, so that coating can be interfered, and plasma plume generated during coating can also interfere with testing. 2. The testing of optical temperature such as laser light cannot be used in the cavity, because the coated dust covers the optical device.
The second problem is even more difficult, and the temperature of the surface of the base tape depends on the temperature itself at the time of entering the coating area and the process of absorbing and releasing heat in the coating area. The temperature of each strip at the moment it enters the coating zone is in turn determined by the process of conductive heating with the heating plate and by the process of radiant heating between the reflecting walls.
The thermocouple group has a high probability of failure in measurement due to the complicated heating structure and environment, which is usually interfered by water cooling, plasma plume, roller defect, and the like. For example, the results of testing a superconducting tape show that the critical current on one side of the tape decays even to 0A due to a low temperature. The temperature drops to 50-100 ℃ below the lower limit of the window when the film is coated according to the judgment of the crystal structure of the film, however, the temperature fluctuation range is only 5-10 ℃ according to the test data of the thermocouple group.
The coated strip can be wound on the heating plate or the heating roller in a reciprocating way in multiple ways, and in order to prevent the strips between the ways from slipping and then contacting with each other mechanically to cause damage, the multiple reciprocating strip ways can be arranged at intervals.
The existing heating system has a plurality of problems, for example, the temperature of a coating area window is narrow, the large-area coating cannot be adapted, and further fineness is needed; the heating surface is contacted with the strip to conduct heat and conduct heat unevenly; the maintenance of the heating surface is difficult, and the change among batches is complex; the condition of edge curling is easy to occur in the strip plating process; the requirement of plating a thin base band cannot be met; the long belt cannot be made; the strip is subjected to tensile transition at high temperature, and the section is arched, and the like.
