Lance75 galvanized square pipeWhat are the main types of production lines

Stage ( & mdash; )When the vehicle is replaced with seamless square tube blank, the material is too soft to affect the requirements, so as to ensure the quality of parts and avoid wrinkles.Lance,The square tube represents the large capacity of the metal material under the action of tension, and the calculation formula is: where: FB -- the strong force borne by the sample when it is broken, n (Newton); So -- original cross-sectional area of sample mm. Yield point (& sigma; s) the stress of metal material with yield phenomenon when the specimen can continue to elongate without increasing (keeping constant) the force during the tensile process, which is called the yield point.The principle of straightening machine is that a disc is divided into two sides to clamp round steel straight lines. Professional square tube, square rectangular tube, seamless square tube, galvanized square tube, galvanized tube, high price, service,Lance273 galvanized square pipe, on-site settlement,LanceDN25 galvanized water pipe, honest operation! The edge is one with radius r, and the center distance between them is adjusted to R + R + D.Arusha,For improper stamping direction, simulation software shall be used in the initial stage of design to ensure that the direction of stamping parts is analyzed, and when the high-quality requirements of components require the re development of molds, the direction shall be adjusted to seamless square tubes. The square tube manufacturer introduces the forming, bending and bending of square tubes. As the name suggests, the bending is compacted, heat strength steel and air valve steel; c. Electric heating alloy steel; d. Wear resistant steel; e. Low temperature steel; f. Electrical steel.

The second is the pickling of the square pipe. Both chemical and electrolytic methods are used when pickling the square pipe. These two methods can remove the oxide skin of the square pipe.Drawing process flow of square tube in the production process of square tube, it needs a lot of processes to complete the production process, so that the production quality of square tube can be more strictly guaranteed. This paper mainly introduces the drawing process flow of square tube. Let's understand it below.Hardness QB square hardness is a pointer to measure the hardness and softness of metal materials. At present,LanceHow much is 50 galvanized square tube, the hardness method is commonly used to measure the hardness in production. It uses the indenter with fixed geometry to measure the hardness value of the metal material surface tested under fixed load according to the degree of hardness.market,Welding is a synthetic gradient material, which can be used as solder to weld special-shaped materials in order to overcome the mismatch of chemical, mechanical and physical properties between base metals.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 tubeSquare tubes are classified by forming: forged steel; Cast steel; Hot rolled steel; Cold drawn steel.

The strength, plasticity and hardness discussed above in fatigue QB are the indicators of the mechanical properties of metals under static load. In fact, many machine parts work under cyclic load, under which fatigue will occur.Quality assuranceB. converter steel: (a) acid converter steel; (b) Basic converter steel. Or (a) bottom blown converter steel; (b) Side blown converter steel; (c) Top blown converter steel.Qb square tube, the selected die material, has obvious hardening in the deep drawing process, resulting in adhesion. Special products such as professional square tube, square rectangular tube, seamless square tube galvanized square tube and galvanized tube are old brands, with advantageous price and guaranteed quality. It makes the surface of workpiece and die easy to scratch and wear, so tool steel for general die can not be used.Principle of cold drawing strengthening: the lattice defects of steel increase during plastic deformation, and the serious distortion of defect lattice will hinder the progress and slip of lattice, so the yield point of steel increases and the plasticity and toughness decrease. Due to the internal stress in plastic deformation, the modulus of steel decreases. The cold drawn reinforcement is stored at room temperature for ~ d or heated to ~ ℃ and maintained for a fixed time. This process is called aging treatment.Lance,Precision pipe is a seamless pipe with high dimensional accuracy and good surface finish for mechanical structure and hydraulic equipment. The selection of precision seamless mechanical structure or hydraulic equipment can greatly save machining hours, improve material rate and improve product quality. Seamless pipe can be divided into hot rolled pipe and cold rolled pipe according to different productionThe difference between hot-dip galvanized square pipe and cold-dip galvanized square pipe is mainly from the following aspects: the appearance of hot-dip galvanized square pipe is slightly rough compared with cold-dip galvanized square pipe; The appearance of cold galvanized square pipe is smooth and bright.Plasticity QB square plasticity refers to the ability of metal materials to produce plastic deformation (deformation) without deformation under load.
