Under certain conditions, the whole roll flatness meter outputs a bimodal waveform signal, which is clearly different from conventional unimodal signal. Since detection relies on extraction of crest values and two waveforms do not have same linearity, presence channels will give rise to errors in calculated distribution. To develop an effective method, it necessary accurately analyze evolution waveforms. In this paper, finite element method used calculate load sensor, stress distribution...
Seamless flatness rollers are the core equipment for cold-rolled strip detection. The change in wear resistance of roller surface-strengthened layer has important guiding significance prediction surface life. experimental results five rounds friction and testing show that volume–wear rate original is only 1.85 × 10−6 mm3 (N·M)−1. After first grinding, decreased was approximately 2.76 second morphology, samples each round showed little difference. average last three test 3.56 (N·M)−1...
For ultra-thin and super-wide cold rolled strips, the flatness problem are still very conspicuous. To ensure that surface of a strip is not scratched, whole-roller seamless meter (abbreviated as WRS meter) developed. Due to structure measuring roll, which has cylindrical holes under its surface, both signal channels adjacent will be significantly interfered when load applied meter, causing measurement errors. eliminate mutual interference between channels, principle channel coupling...
During the process of hot rolling, seam defects often appear on edges interstitial‐free (IF) steel, which seriously affects product quality and yield. To this end, macro‐ micromorphology edge are analyzed, their specific characteristics summarized, defect cast slab rolling experiment is conducted. The shows that pore, crack, slag inclusion not causes defects. Then, through a combination theoretical analysis, actual parameters’ detection, experiments, formation mechanisms evidently side...
Cold-rolled non-oriented silicon strip is widely used, and users have strict requirements for its transverse thickness difference. It of great significance to study the quantitative relationship between difference incoming section profile cold-rolled formulate appropriate control indexes hot-rolled profile. To achieve above purpose, this paper first proposes a method describe strip. A mechanism model predicting established. Based on characteristics neural network transfer learning,...
Contact-type flatness meters are the key detection equipment in production of high-end cold-rolled thin strips. The surface performance a meter roller is very important to improve its service life and ensure quality strip products. To wear resistance prolong seamless roller, it was subjected strengthening treatment by laser cladding an Fe-based wear-resistant alloy. strengthened quenching determined tests. results show that cladding-strengthened layer forms solid metallurgical bond with...
In recent years, our country’s transmission lines have often been in danger due to geological disasters such as landslides when passing through fragile environments, which has brought great challenges and risks the operation maintenance of lines. order understand impact line towers on tower foundation slopes under heavy rainfall conditions, influence at different locations, intensities, slope stability was analyzed by using Geo-Studio finite element analysis software. The results show that...
Compared with the sectional roller flatness meter, integral meter is more suitable for products higher requirements on surface quality, and thus becomes trend of contact-type cold rolling. Due to its structure design, some problems arise. Under action dead weight or an external load, deflection deformation changes stress state sensor installed inside it generates additional signal. This paper studies mechanism signal recognition elimination method. First, according detection connection mode...
One of the most significant pieces linear infrastructure in China is Middle Route South-to-North Water Diversion Project (MR-SNWDP), a large section which consists an expansive soil slope (ESS) that threatens safety canal. Here, we prepared 144 Sentinel-1 data from May 2017 to July 2022 study behavior ESS canal Huixian City MR-SNWDP. Then, Elastoplastic Deformation model under Wetting and Heating Effects (EDWHE) was employed accurately characterize displacement ESS. The InSAR results...
