Square tube is a very good steel in economic construction. There are many kinds and principles of cold drawing. You may still have a lot of insufficient understanding of the cold drawing principle of each other's pipe. Next, pig iron, ferroalloy, cast iron, etc. Steel and pig iron are alloys based on iron square tube and carbon as the main added element,There are many forms of heating furnace, but the ring heating furnace is mainly used. The heating furnace has an annular furnace bottom, which can rotate slowly, the blank is loaded along the diameter direction of the furnace bottom from the inlet, and can be heated and homogenized to the specified temperature when it is used at the outlet. The production process of seamless square tube is relatively slow, and the heating operation especially needs patience. Because if the heating operation is not standardized, cracks folding and eccentricity on the inner or outer surface of the tube blank will only produce waste products and defective products.Normalized: A. pearlite steel; b. Bainitic steel; c. Martensitic steel; d. Austenitic steel.Cincinnati,Square tube is a very good steel in economic construction. There are many kinds and principles of cold drawing. You may still have a lot of insufficient understanding of the cold drawing principle of each other's pipe. Next, I'll lead you to learn its cold drawing principle.Classification of square pipe material square pipe is divided into ordinary carbon steel square pipe and low alloy square pipe according to material. Ordinary carbon steel is divided into Q Q q SS, # steel, # steel, etc; Low alloy steels are divided into q Mn, Q, St-, etc.The principle is similar to that of the plate rolling machine. The bending machine can determine a circle. Adjust the height to adjust the curvature.

: it refers to the processing of square tube, which places metal in a closed Jane and applies pressure at the end to extrude the metal from the specified die hole to obtain finished products with the same shape and size. It is mostly used to produce non-ferrous metal materials. Square tube ferrous metal, steel and non-ferrous metal. Before introducing the classification of steel, briefly introduce the basic concepts of ferrous metal, square tube steel and non-ferrous metal.The standard quantity of combustible and nonflammable square pipes is gbt- (gbt-). The representative material is l-l pipeline steel. Professional square pipes, square rectangular pipes, seamless square pipes, galvanized square pipes and galvanized pipes are of high quality and low price. They are fire-resistant, waterproof, high temperature resistant, durable, safe and reliable. They are mainly used to transport combustible and nonflammable fluids with high requirements.Empty bending empty bending is the bending moment formed in one direction between the outer roll and the outer wall of the tube blank to bend the strip. Empty bending will compress the bending line, the compression effect will lengthen the bending line longitudinally, and the metal at the bending will accumulate and thicken, which is the compression thickening effect of empty bending.Convenient and efficient,Qb square tube, qb square tube, qb square tube, QB square tube, QB square tube and hot-rolled right angle square tube are of good quality and excellent quality. We have become a supplier of many enterprises. Qb square tube and I-beam are two products with different shapes. Under the condition of the same material, the bearing capacity of steel is the same, but their uses are very different. The shape is different. Qb square tube is a cuboid and I-beam is in I-shape. The purpose is different. I-beam can be used as span and support. Square pipe is a little worse than span. It is no problem to do support. However, the specific selection of steel depends on the requirements of the project. Square tube practical application square tube for structure (gbt-) is a square tube for general structure and mechanical structure.The general delivery length of qb square pipe is mm-mm mostly mm and mm. Qb square tube is allowed to deliver short length and non fixed length products not less than mm, or in the form of interface tubePut the pig iron for steelmaking into the steelmaking furnace according to the specified process to obtain steel. The products of steel include ingots, continuous casting billets and various steel castings made of straight square tubes. Generally speaking, steel refers to the steel rolled into various square tubes. Square tube steel belongs to ferrous metal, but steel is not completely equal to ferrous metal.

Square tubes for petroleum cracking (gb-) are furnace tubes, heat exchangers and pipeline square tubes suitable for petroleum refineries.Finance Department,Main uses of square tube: square tube is mainly used in tap water engineering, petrochemical industry, chemical industry, agricultural irrigation and urban construction. It is one of the key products developed.Square pipe is an important pipe. Its application in various fields has different performance. According to its different performance, we have carried out different transformation on the other pipe to ensure that the square pipe can be better used. We should make the right choice when purchasing. Below I will introduce the correct way of painting the lower pipe.Change to square pipe: generally, the strip steel is unpacked, leveled, crimped and welded to form a round pipe,Clarupinadvtavo114 galvanized square pipe, then rolled into a square pipe from the round pipe, and then cut into the required length. Stage ( & mdash; )Clarupinadvtavo,It is the process of drawing the die hole of the rolled metal blank (shape, pipe, product,ClarupinadvtavoPrice list of galvanized pipe,ClarupinadvtavoProcessing galvanized square pipe, etc.) into a section to reduce the length and increase. It is mostly used for cold processing.After spraying (throwing) derusting, it can not only expand the physical adsorption on the pipe surface, but also enhance the mechanical adhesion between the layer and the pipe surface. Therefore, spray (throwing) derusting is an ideal derusting method for pipelines. Generally speaking, shot blasting (sand) is mainly used for the inner surface treatment of the pipe, and shot blasting (sand) is mainly used for the outer surface treatment of the pipe. Several problems should be paid attention to in derusting by spraying (throwing).There are many ways of ignition, such as arc, electric spark, strong current, high-temperature furnace, electron beam, laser high-temperature radiation, chemical furnace, etc.
