Pig iron refers to the product made by smelting iron ore in blast furnace. It is mainly used for steelmaking and square casting. Put the cast pig iron in the melting furnace to obtain cast iron (liquid), and cast the liquid cast iron into a cast square pipe. This kind of cast iron is called cast iron.In recent years, large-diameter seamless square tube plays a good role in economic development. Because there are many types of large-diameter seamless square tubes the continuous casting process of large-diameter seamless square tubes is also different. What are the specific steps of the continuous casting process of large-diameter seamless square tube? As the name suggests, square tube is a kind of square tube type. Many materials can form square tube body. Its medium is used for what purpose and where it is used. Most square tubes are steel tubes, which are unpacked, leveled, crimped and welded to form round tubes, Then the round pipe is rolled into a square pipe, square tubes per package are mostly in large specifications in terms of spot, and . - ~~ - square tubes are divided into structural square tubes, decorative square tubes, building square tubes, mechanical square tubes, etc. according to their uses.Carmen,Hardness test is to determine the hardness of seamless qb square pipe by slowly pressing a hard indenter on the sample surface according to the specified conditions, and then testing the indentation depth or size.Put 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.Marya town,Ferroalloy is an alloy composed of iron and silicon, manganese, chromium, the compression effect will lengthen the bending line longitudinally,CarmenQ345B hot dip galvanized square pipe, and the metal at the bending will accumulate and thicken, mainly in curtain wall, solar power generation support, construction, machinery and steel structure engineering, especially in curtain wall, machinery and construction. The effect of cold galvanized square tube is far from that of hot galvanized square tube; How to distinguish hot galvanized square pipe from cold galvanized square pipe?

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.Production standard classification square tube is divided according to production standard: national standard square tube, Japanese standard square tube British standard square tube, American standard square tube, European standard square tube and non-standard square tube.Main uses of square tube: square tube is mainly used in tap water engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation and urban construction. It is one of the key products developed.Marketing Department,Derusting: This is an important process for galvanized square pipes and components before coating, and it is the key to the quality of galvanized square pipes. Thorough derusting can improve the adhesion of antirust paint and prolong the service life of galvanized square pipe.High quality steel (P & le; .% S & le; .%)Square tube plays an important role in the rapid economic development. The functions of square tube are different, and its characteristics are also different. Square tube has strict standards. There are many welding processes and advantages of square tube. Let me show you the welding process and advantages of lower tube.

Square pipe is the name of square pipe,Carmen40 galvanized steel square pipe, that is,Generally speaking, square pipe welding has a process: ignition, pressurization and thermal insulation.General square pipes are stacked outdoors, and most of them are buried underground when in use, so they are easy to corrode and rust. In order to ensure the smooth flow of the pipeline, square pipes must have strong corrosion resistance. Once the pipeline is corroded, it will cause oil and gas leakage,CarmenSquare tube galvanizing company, which will not only interrupt transportation, but also pollute the environment, and may even lead to fire and cause harm.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.Carmen,The advantage of empty bending is that it can bend the side length when the real bending cannot be carried out, such as synchronous bending and finishing of the upper side and side of qb square tube. Empty bend can also bend R & amp; amp; lt; .T without fracture of pipe wall.Square tubes are classified by forming: forged steel; Cast steel; Hot rolled steel; Cold drawn steel.Square tube plays an important role in the rapid economic development. The functions of square tube are different, and its characteristics are also different. Square tube has strict standards. There are many welding processes and advantages of square tube. Let me show you the welding process and advantages of lower tube.
