<p> Huaibei Xiangshan 20G steel plate specifications of quality and quality heat treatment and performance alloy carburizing steel heat treatment process are generally carburized directly after quenching, and then low temperature tempering. After heat treatment, the standard of Huaibei Xiangshan 20G steel plate, the surface carburized layer is alloy cementite + tempered martensite + a small amount of retained austenite, hardness 60HRC ~ 62HRC. The core is related to the hardenability of the steel and the cross-section dimensions of the part. When fully hardened, it is low-carbon tempered martensite, with a hardness of 40HRC ~ 48HRC; in most cases, it is tempered martensite, tempered martensite and a small amount of ferrite. Body, Huaibei Xiangshan 20G steel plate wholesale, hardness 25HRC ~ 40HRC. Heart toughness is generally higher than 700 / m2. The alloy quenched and tempered steel is widely used in various important parts on automobiles, tractors, machine tools and other machines, such as gears, shafts, connecting rods, bolts, etc. Quality management Huaibei Xiangshan stretch straightening steel sheet after hot rolling and cold rolling. Stretch straightening is a flattening method to be used. Stretch straightening is a combination of stretching and bending technology, which requires low operating power input. Can effectively get excellent straightness correction ability, for similar defects. Flatness can be increased by 100 times. Hazen believes that the roller tensioner of the leveler usually produces 0.002% of the absolute elongation of the steel belt between 15% and 25% of the yield stress on the steel belt. Adjusting the elongation of the steel strip according to the size of the sickle bend can correct the strip shape defects, and the operation is relatively simple. The circulating cooler used in the market has the characteristics of small footprint, uniform cooling, safety and reliability. And adopt modular design, according to the capacity of the furnace can increase or decrease the number of modules, thus the cooling capacity of the furnace type. Understand the quality and standard issues of galvanized strip steel Standard problems will greatly help the selection of galvanized strip steel. Inspection conclusions Liaoning agent Huaibei Xiangshan 20G steel plate with high quality and quality cold rolled strip cold rolled strip is intended to avoid plastic instability of the annealed steel sheet during stamping and improve the quality of the steel sheet (flatness and surface condition). There are two types of single-stand reversing and double-stand rolling mills. The flattening compression rate is 0.5 ~ 4%. The double-stand flat rolling mill has high efficiency and high compression ratio, and can also be used for sub-cold rolling at the same time to improve the rolling of thin steel plates. If used in conjunction with the stand continuous rolling mill, it can be good for strip coils of 0.10 ~ 0.15mm. Customer First Quality Inspection Report </ p> <p>

Huaibei Xiangshan 20G steel plate specifications are excellent


</ p> <p> Huaibei Xiangshan 20G steel plate has high specifications and quality. Huaibei Xiangshan caused the under pickling because of the uneven thickness of the iron oxide scale, the thicker iron oxide scale requires a longer pickling time, and Fe0 in it is decomposed. It becomes more difficult to dissolve Fe2O3 (Fe3O; the strip has a large wave and sickle bend. During the pickling process, the wave part or the bent part is not immersed in the acid solution, which causes leak pickling; the mechanical scales are not broken before pickling Perfect, especially the iron on both sides of the strip has not been broken, etc. The quality management of the supply chain is used for simple stamping parts (DQ). The measures to prevent scratches are the rolling parts and guides of regular units, and the equipment is maintained. How can Huludao Rust. The phenomenon that the rust layer reappears on the surface after pickling of raw materials is called the cause of rust formation: a little acid solution remains on the surface after pickling of the strip (steel plate), or the strip does not reach complete dryness after cleaning, and the surface is regenerated In addition, the strip steel stays in high cleaning water for too long after pickling, and it will also cause rusting. Huaibei Xiangshan 20G steel plate is of high quality and convenient and efficient galvanized steel strip. Minute Importantly, the galvanized steel strip factory can guarantee that the data of each product consumed conforms to the specifications, so consumers in need can directly come to the galvanized steel strip factory and stop choosing.? About the introduction of galvanized strip steel processing, metal as The supplier of galvanized strip steel, we have already introduced what is galvanized strip steel. Galvanized strip steel is a raw material called (zinc) coated with cold or hot rolled long and narrow long steel plates to varying degrees. Today, we will introduce you to the knowledge about the characteristics of galvanized strip steel. Follow us to take a look at it: The improved Sengimir method has the characteristics of shortening the furnace length and high heating efficiency due to the preheating section and the open flame heating section. The open flame also It can burn off some rolling oil and reduce the burden of strip pre-treatment. Equipment management </ p> <p>

</ p> <p> Huaibei Xiangshan 20G steel plate is of high quality, safe, and better than pickling. The residence time of the metal in the acid solution is too long, so that under the action of the acid solution, the surface of the Huaibe Xiangshan 20G steel plate gradually becomes rough and dull, which is called over pickling. The customer comes first. Striped black spots on the surface of steel strips after pickling are called inclusions. It is due to the formation of scale on hot rolling. Such defects cannot be removed by pickling. When it is cold-rolled, the black dots expand into black strips, which greatly reduces the impact performance of the finished steel sheet. Goal </ p>
