Description

technical field [0001] The invention relates to the field of thermal analog cooling control. Background technique [0002] It is too costly to conduct industrial experiments directly on the development of new steel materials, quality improvement and process improvement, and it is very unrealistic. Moreover, it is difficult to accurately control many physical parameters. Using the physical simulation technology of thermal simulation testing machine Laboratory reproduction and simulation. There are many new products in hot rolling production that put forward higher requirements for cooling control technology. Laminar cooling technology has become a necessary cooling control link in various steel rolling production lines, and is one of the important control links in the hot strip steel control system. The laminar flow cooling device is the key equipment for hot-rolled strip production. Its function is to obtain a suitable strip coiling temperature and control the final mechani...

Problems solved by technology

The utility model provides the upper and lower sets of tubular nozzles, which cannot form a full coverage of all areas of the strip at the same time. Even if the nozzles can rotate, they are fixed at a certain position, and the linearly distributed nozzle holes are still on the strip. Cooling at local locations cannot achieve uniform cooling of the overall strip, let alone simulate the high cooling rate of the laminar flow cooling process for a full-scale sample of hot-rolled strip steel. In addition, the utility model does not mention the strip How to achieve the anti-oxidation function in the cooling process, it is impossible to realize the annealing process under the protection of the atmosphere

[0005] Chinese patent CN201527376U discloses an air jet cooling device. The air nozzle configured in the device cools the strip-shaped steel plate sample in one direction. The air source comes from an air compressor. This cooling method and cooling medium gradually increase with the thickness of the steel plate. The cooling capacity is very limited and greatly attenuated, and it is impossible to simulate the laminar cooling process of hot rolling or hot continuous rolling; in addition, this utility model cannot provide the anti-oxidation function of the steel plate during the controlled cooling process, and it cannot achieve the performance of the atmosphere annealing process. simulation
