Most objects are prone to oxidation and corrosion at high temperatures, especially metals such as steel, which are commonly subjected to high-temperature oxidation and corrosion. Steel is prone to react and oxidize in contact with air in high-temperature environments, causing the effective substances of steel metal and the generation of other ineffective substances from oxygen in the air, which greatly affects the structure, use, characteristics…
Hot rolled steel plates and strip products are one of the important steel varieties. With the application and development of hot-rolled plates in various aspects, users have increasingly strict requirements for products. Users not only focus on the quality of steel plates, but also pay more attention to the appearance quality of products.To a large extent, appearance quality is one of the important indicators for evaluating the quality of hot-ro…
Gruck sensorThe preparation work area of the steel rolling plant always adheres to the principle of cost reduction and efficiency improvement, comprehensively strengthens equipment control, continuously improves problem-solving ability, and ensures stable and smooth production. Through active exploration and bold practice, technical improvements have been implemented to address the shortcomings of hydraulic lifting equipment for rolling mills, a…
Hot rolled steel plateBy definition, steel ingots or billets are difficult to deform and process at room temperature. Generally, they are heated to 1100-1250 ℃ for rolling, and this rolling process is called hot rolling. The temperature of hot-rolled plate is high, so the deformation resistance is small, which can achieve a large amount of deformation. Taking the rolling of steel plates as an example, the thickness of continuous casting billets…
SummaryIn order to study the thickness and structure of iron oxide scale in hot-rolled structural steel and its impact on pickling quality, two hot rolling processes, "high temperature, low cooling rate" and "low temperature, high cooling rate", were designed, and the production and preparation of hot-rolled structural steel were carried out. The thickness distribution, structural characteristics, and surface morphology of ox…
