According to smelting classification and furnace type, A. open hearth steel: (a) acid open hearth steel; (b) Alkaline open hearth steel.Stage ( & mdash; )Baines,Square tubes can be degreased with organic solvents (vinyl chloride, vinyl chloride, carbon chloride, industrial solvents, benzene, acetone, etc.), concentrated or alkaline solution. Industrial vinyl chloride is suitable for degreasing metal parts; Industrial chlorinated carbon is suitable for degreasing ferrous metal and non-metallic parts; Vinyl chloride is suitable for degreasing metal parts and non-ferrous metal parts; The industrial concentration shall not be less than %, which is suitable for manual scrubbing of the inner surface of the container with low degreasing requirements; % concentrated, suitable for degreasing some pipe fittings and porcelain rings of concentrated device.Ship carbon steel square pipe (gb-) is a carbon steel square pipe for ship class I pressure pipe system, class II pressure pipe system, boiler and superheater. It is a long-term business square pipe square pipe,BainesGalvanized thick wall square pipe, seamless square pipe, galvanized square pipe and galvanized pipe. Welcome to consult. The working temperature of carbon steel square pipe wall shall not exceed ℃,High density may not be obtained by simple pressurization, and insulation shall be carried out at the same time.It should be noted that the position of the disc from the calibration line can be adjusted according to the reinforcement diameter and R and R can be equal or different.It is the process of drawing the die hole of the rolled metal blank (shape,BainesHow much is a meter of galvanized round pipe, pipe, product, etc.) into a section to reduce the length and increase. It is mostly used for cold processing.

B. tool steel: (a) carbon tool steel; (b) Alloy tool steel; (c) High speed tool steel.Large fillet radius, insufficient blank holder area, easy to produce unstable wrinkles; If the fillet is too small, the resistance of the material into the die will increase in the deformation process, and the material is not easy to move and transfer inward, thus increasing the large tensile stress in the force transfer area, which may lead to tensile cracking.Square tube nonferrous metals, also known as non-ferrous metals, refer to metals and alloys other than ferrous metals, such as copper, tin, lead, zinc, aluminum, brass, bronze, aluminum alloy and bearing alloy. In addition, chromium, nickel, manganese, molybdenum, cobalt square tube, vanadium, tungsten, titanium, etc. are also used in industry. These metals are mainly used as alloy additives to improve the performance of metals. Tungsten, square tube titanium, molybdenum, etc. are mostly used to produce cemented carbide for tools. The above non-ferrous metals are called industrial metals. In addition there are precious metals: platinum, gold, silver and rare metals, including radioactive square tubes.Quality assuranceWith the progress of the times and the development of science and technology, square tubes will also rust for a long time. How to improve the rust resistance of square tubes and what are its rust resistance? Let me give you a detailed introduction below.The disadvantage of empty bending is that when the upper side and side are synchronously empty bending, the forming force is easy to exceed the critical point due to the pressure generated by the upper roll and the lower roll at the same time, resulting in edge instability and concave, and will also affect the stable operation and forming quality of the unit. This is also the different characteristics of qb square tube and round tube empty bending. The concept of square tube: square tube is the pressure processing of ingot, billet or square tube Make materials of all shapes, sizes and properties we need.The reason why the surface of fake and shoddy materials is easy to crack is that its blank is adobe with many air holes. During the cooling process, the adobe has cracks due to the action of thermal stress, and there are cracks after rolling.

Plasticity QB square plasticity refers to the ability of metal materials to produce plastic deformation (deformation) without deformation under load.Market trend,BainesSquare tube price,B. 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.The welded joints of square pipes are subject to on-line continuous ultrasonic automatic flaw detector to ensure the NDT coverage of spiral welds. If there are defects, continuous casting billets and various steel castings made of straight square tubes. Generally speaking, but steel is not completely equal to ferrous metal.Baines,Square tubes have different functions and different characteristics. Square tubes of various specifications, square rectangular tubes, seamless square tubes, galvanized square tubes and galvanized tubes are welcome to waste merchants, enterprises and power departments to visit and negotiate! Oxidation will also occur on the surface of square tubes after long-term use. What should we do if oxidation occurs? Let me give you a detailed introduction on how to remove square tubes Oxide scale.Strength QB square strength refers to the performance of metal materials under static load (excessive plastic deformation or fracture). Since the action modes of load include tension, compression, bending and shear, the strength is also divided into tensile strength, compressive strength, flexural strength and shear strength. There is often a certain between various strengths. Generally, tensile strength is used as the basic strength indicator. 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 is rolled in the annular pass composed of variable cross-section circular hole groove and fixed conical plug. Cold drawing is usually carried out on single chain or double chain cold drawing machine. This method is to put the heated pipe blank in a closed cylinder, and the perforated rod and rod move to extrude the part from the smaller die hole. This method can produce steel pipe with smaller diameter.Stage ( & mdash; )
