This invention discloses a device and method for evaluating the proppant-carrying performance of fracturing fluid with continuously adjustable proppant concentration, relating to the field of oil and gas field production enhancement. The device includes a reactor body. The reactor body is equipped with a stirring assembly, a proppant-adding assembly, a heating assembly, and a visualization window. The proppant-adding assembly achieves quantitative and batch-wise addition of proppant within the high-pressure reactor through a series of upper valves, a proppant-to-be-added section, and a lower valve. The method includes: applying experimental temperature and pressure conditions, initiating stirring to simulate dynamic flow, continuously adding proppant in batches through the proppant-adding assembly, monitoring the proppant status in real time using a vision system, and recording and analyzing data to obtain a continuous proppant-carrying performance curve and a limit proppant-carrying value. This invention solves the problem of existing technologies being unable to conduct continuous gradient testing of proppant concentration under high-temperature and high-pressure dynamic conditions, and can obtain complete proppant-carrying performance data of fracturing fluid from low concentration to limit concentration in one go, with evaluation results closer to actual downhole operating conditions.

This invention provides a comprehensive, coordinated control method for reducing the total curvature of long, fixed-length small square billets. It covers three stages: continuous casting process optimization, cooling bed control, and slow cooling during stacking. Based on the metallurgical mechanism of bainitic phase transformation, a complete temperature control chain is constructed to systematically eliminate multiple sources of curvature, including uneven cooling, phase transformation stress, and additional stress from stacking. Compared with existing technologies, this invention requires no additional specialized equipment and, without significantly increasing production costs, ensures that the total curvature of small square billets is stably controlled within 60mm, with a curvature per meter not exceeding 10mm. This significantly improves product quality, production efficiency, and production safety, effectively solving technical problems such as difficulty in charging the heating furnace, rolling defects, high scrap rates, and increased production costs caused by excessive curvature of small square billets, thus providing qualified billets for subsequent steel rolling production.
