The standard size industry of the Shigatse Geelong galvanized checkered plate has good water tightness, and the locks at the joints of the steel sheet piles are tightly integrated to prevent natural seepage. Excessive quality of Xigaze Geelong's alloying elements that cause secondary hardening. Causes of secondary hardening. Transformation of residual austenite in alloy elements. Precipitation hardening of Mn, Mo, W, Cr, Ni, Co, VV, Mo, W, Cr, Ni, and Co. At high levels and in the presence of other alloying elements, it is effective because it can produce a diffusely distributed intermetallic compound. It is strongly recommended that the range of blanking standards: This standard applies to the blanking process of raw materials. Suitable for flame cutting and plasma cutting. Click to see Fushun surface processing code: matte finish rolling is D, bright finish rolling is B. Cold rolled carbon sheet is used like SPCC-SD for standard quenched and tempered finish. Another example is SPCCT-SB, which refers to cold-rolled carbon sheet that requires standard hardening and bright processing and requires mechanical properties. The property rights are available for grades, corresponding standards and use categories. Steel grade grades. Supply grades. Corresponding grades. Low-carbon steel and ultra-low-carbon steel commercial grade (CQ). When supporting the pile, it can be customized in advance before leaving the factory.

The standard size industry outlook of the Shigatse Geelong galvanized checkered plate shows: DR + iron loss value (magnetism induced by 50HZ repetitive magnetization and sinusoidal change is 5T iron loss per unit weight) + 100 Times. For example, DR510-50 indicates a hot-rolled silicon steel sheet with an iron loss value of 0.5 mm in thickness. Main characteristics: corrosion resistance, paintability, formability and spot welding. According to good specifications and grades, the service life of carbon sleeves can be distinguished. The higher the good grade, the shorter the life of the carbon sleeve; the narrower the good specification, the shorter the life of the carbon sleeve. It is recommended that the service life of the carbon jacket of the low-end continuous annealing unit is 4-6 months. The mature and advanced annealing process and parameters can be used for a variety of products; the waste heat of the annealing furnace adopts a multi-stage heat exchange system, which is used for the system, drying and cleaning systems, etc., and has significant energy saving effects. Except for Co and Al, most alloy elements in Xigaze Geelong decrease the Ms and Mf points. The order of its magnitude is: Mn, Cr, Ni, Mo, W, Si. Among them, Mn has a strong effect, and Si has virtually no effect. The decrease of Ms and Mf points increases the amount of retained austenite in the steel after quenching. When the amount of retained austenite is too large, it can be cold-treated (cooled below the Mf point) to transform it into martensite; or subjected to multiple tempering, at this time, the residual austenite will cause Ms and Mf due to precipitation of alloy carbides The point rises and changes to martensite or bainite during cooling (so-called sub-quenching occurs). The radiant furnace and cooling section of the good annealing furnace are modular design, which is easy to install and maintain. The flatness of the plate and the large allowable scale of the sickle must be delimited.  Editing and development of related materials The United States established a continuous hot-dip galvanized strip steel line in 1937, and a continuous electro-galvanized strip steel line was established in the United States in 1942. It has been in industrial use for over 70 years. Knowledge Langfang, such as 50A470, indicates a cold-rolled non-oriented silicon steel strip with a thickness of 0.5mm and a guaranteed iron loss value of ≤ 7. The standard size industry outlook of Shigatse Geelong Galvanized Checkered Plate Roller Straighteners Roller Straighteners are mostly used on the feed lines for finishing and advanced processing. The working principle of roller straightening is that at below zero, the steel plate is repeatedly bent repeatedly, and the outer metal of the plate produces a certain yield on the cross section of the steel strip, forming a relatively flat product. The metal in the middle layer of the steel plate does not yield, and this straightening method does not cause a fixed elongation of the entire steel plate. Some areas in the width of the material are bent with a small radius, which makes the shorter or tighter part stretch. The standard size of the Shigatse Giron galvanized pattern plate is only limited to the outer metal of the steel strip. Different from stretch straightening, the level of flatness that the final product can reach is higher. The resulting residual stresses can be eliminated during progressive bending or shearing. Roller straightening can correct steel plate and various defects, but cannot correct warping. Edge warping and intermediate waves can be corrected by differently arranged work rolls. Word of mouth recommends SPHC-the first S is the abbreviation of Steel, P is the abbreviation of Plate, H is the abbreviation of Hot Heat, C is the abbreviation of Commercial Commercial, and hot rolled steel plate and strip are generally used.

Shigatse Geelong Galvanized Checkered Plate Standard Dimension Industry Outlook Customized Other measures such as straightening with a straightener, changing the stand spacing, using rollers, and adjusting the roll gap for each stand can reduce or eliminate longitudinal bending. It should be noted that adjusting the roll gap of each pass to reduce longitudinal bending requires skilled techniques. Operates many steel grades in 15MnVN medium strength steel. It has high strength and good toughness, weldability and low temperature toughness. It is widely used in bridges, boilers, ships and other large structures. The length can be customized according to customer requirements. The specifications and sizes of the Shigatse Giron galvanized checkered plate bring great convenience to the construction and reduce costs. The development of specialized sealing and imprinting processes is a good example of this. For example, HOESCH patent system, its emergence opened up a new field of steel sheet piles in terms of pollution. After designing the brand galvanized steel strip, we must pay attention to the time when we choose this product in the market. We must carefully look at whether the data marked by the province can differ from those of the national rules. It is assumed that there is no data on the surface of the product we choose. It is noted that the consumer can stop the interrogation like this. If necessary, you can check the product's eligibility. Shigatse Geelong Galvanized Check Sheet Manufacturer, so that the product we choose can ensure that the quality will not present problems. Consumers can use it with confidence. Application editing functions, appearance, and practical value are the standards people use today when choosing building materials. Steel sheet piles are in line with the above: the elements of its components have a simple and practical structure that meets all the requirements for structural safety and environmental protection, and buildings completed with steel sheet piles have great appeal.
