Detailed Product Description: | Steel hypothetical question hypothetical restraint should note: In order to reduce steel welding deformation. Welds should be as symmetrical arrangement; not arbitrarily increase the weld thickness; the premise of ensuring safety of welds should not be too concentrated. Construction Control and Prevention. Prefabricated moral restraint, not segmented measurement; after the release of the steel wire size should be the amount of the full-length sub dimensions. Save the cumulative size. For members require a higher dimension, should put the line marked like red eyes. To ensure that the cutting edge of the cutting quality, 12mm below the board should try to mechanical cutting. When cutting with gas welding steel, steel specifications should be considered to extend the margin 2-3mm aside. Should be corrected; deformed steel beyond designated tolerance range. If the allowable value for the scale delineation of cold deformation correction and cold bending radius of curvature of the minimum and maximum bending vectors should be used to correct or use steel pressure jack homemade correct tools to perform cold correction, incident corrections. Style pattern shown in execution; or if the deformation of a steel member of a larger linear expansion coefficient -6 SU 1.210-5 / ℃, Dongguan elongated steel processing in various directions, due to the high temperature heating zone, the heating zone steel shrinkage, and low temperature adjacent the heating zone, which restricts the expansion of the heating zone to the surrounding, so that the metal of the heating zone is squeezed, when the heating temperature must be reached, the heating zone the metal due to compression plastic deformation, the metal heating zone change crystal structure. Upon cooling to the original temperature, in addition to the length of the contraction before heating, but also to extend the rate of 1.4810-6 / ℃ further contraction in steel welding, so extend the length after the previous heating has been shortened. Anti-corrosion coating on steel processing research in recent years, the extraordinarily rapid development of steel construction. Steel also revealed wide application range of shortcomings, the more serious is the corrosion of steel. Corrosion protection of steel structures were reviewed. With the wide application of steel carport steel construction, due to the characteristics of the steel structure steel itself, and based on the construction of safety and durability, corrosion of steel structures has become increasingly prominent problem. At present, the world each year due to the economic losses caused by corrosion of the steel structure has been up to hundreds of billions of dollars; and as a result of an accident caused by corrosion of steel endanger the safe operation of the structure, the corrosion caused by a catastrophic accident has a lot to see. For welded steel and steel to withstand greater stress situations and under stress, the corrosion will be faster. Steel processing Dongguan, Huizhou, steel, Peng Jian Steel Co., Ltd., Dongguan City, Peng was built by steel. Steel Co., Ltd., Dongguan City, Peng Jian (dgpengjian.cn) strong, credible, in Dongguan, Guangdong steel industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Peng built into the brilliant steel and you work for a better future! |
