Application fields of H-section steel
H-section steel is a kind of economic section high-efficiency profile with more optimized section area distribution and more reasonable strength-weight ratio. It is named because its section is the same as the English letter “H”. Because H-beam is arranged at right angles in all parts, H-beam has the advantages of strong bending resistance, simple construction, cost saving and light structure weight in all directions. Based on the above advantages, H-shaped steel is widely used in various civil and industrial structures, various large-span industrial buildings and modern high-rise buildings, especially in areas with frequent seismic activity and under high temperature working conditions, requiring large bridges with large bearing capacity, good cross-section stability and long span, heavy equipment, highway, ship skeleton, mine support and foundation. Handling and dam engineering, various machine components.
Processing flow of H-section steel
H-section steel can be produced by welding or rolling. Welding H-section steel is to cut strip with suitable thickness into suitable width and weld flange and web together in continuous welding unit. The processing flow of welded H-section steel is as follows:
①Testing of Raw Materials——②Computer Typesetting, Blanking——③Assembly——④Welding——⑤Weld Seam Inspection and Root Cleaning——⑥Denaturation Control——⑦Test Assembling——⑧Dimensional Inspection Verification——⑨Sand Blasting and Rust Removal——⑩Painting and Numbering Packaging
Universal rolling mill is often used to roll H-beam in modern rolling production. The web of H-beam is rolled between the upper and lower horizontal rolls, while the flange is rolled between the side of the horizontal roll and the vertical roll at the same time. The processing flow of hot rolled H-beam is as follows:
①Special-shaped Continuous Casting Embryo——②Walking Beam Heating Furnace——③High Pressure Water Descaling——④Two-roll Reversible Roughing Mill——⑤Cantilever Straightener——⑥Walking Beam Cold Bed——⑦Hot Saw——⑧Universal Mill Set——⑨Marshalling Stand——⑩Cold Saw——⑪Stacking and Packing
