Molding Process
Hot rolling forming：After heating the steel to a certain temperature，Roll it into a square cross-section through rolling equipment。Cubiculum calidum calidum caliginem caliginem caliginem quadratum habet accuracionem dimensionalem altam，Qualitate superficie bona。
Constellation name (optional)：Stellam in intersectionem quadratum ad temperaturam cubiculi ut utilizat arma bending。Cubiculae quadratis calidissimas formatae carbonibus sunt suitae ad producendum tubas quadratas parvulas et thinas。
procedura
Using high-frequency welding or submerged arc welding technology to weld the formed steel in square tubes。Strict control of welding parameters is required during the welding process，Configurare qualitatem et fortitudinem plagae。
Yüzey tedavisi
Cubiculum quadratum Carbonum post fabricationem，Usually requires surface treatment。Common surface treatment methods include sandblasting for rust removal、Painting and anti-corrosion measures, etc.。Removit pulverem ventilatorum ferre potest scalam oxidae et impuritatem super superficiem steelae auferre，Anti corrosione pingam diffusione corrosion resistentiam quadratis tubarum improvere potest。
tres、Specificatio
Longitudo longitudinis lateris
Longitudo longitudinis anguli tubae quadraticorum carbonium usus ex20mmadvenient300mmunequal。ex exemplo，20mm×20mmSmall square tubes are commonly used for lightweight steel structures and decorative purposes，But300mm×300mmThe large-size square tube is used for large-scale building structures and bridge construction。
Distancia murum
Murus densitudo generale ab1.0mmadvenient10.0mmunequal。Turbo quadraticum carbonium fustum fustum（secundum1.0mm-2.0mm）Suitable for light weight structures and decorative purposes，And thick walled carbon steel square tube（secundum6.0mm-10.0mm）Utilium est pro componentibus structuralis qui multas cargas resistant。
length specification
Longitudo standard normale est6oryzam，But other lengths can also be customized according to customer needs，secundum3oryzam、4oryzam、8Rica, etc.。In construction，Longer carbon steel square tubas can reduce the number of joints，Improver construction efficiency。
quattuor、area aplicationis
Construction field
Structura Stellae aedificata：Cubiculum quadratum Carbonum est unus ex principibus materialibus aedificiorum structurae steelae。It can be used to construct the framework structure of buildings，Like a beam、column、Support, etc。ex exemplo，In magna fabrica aedificio、stadium、In exhibitionis domibus et alias aedificationes，Structura quadrata tubae quadrata carbon constituit sufficientem fortitudinem et stabilitatem，Simultaneously possessing excellent seismic performance。
Utrum ornatum：Cubiculae quadraticae Carbon steel etiam in aedificiis decorativa utili potest，Like a railing、handrail、Skeleton murum cortinae, etc.。Per pingam aspersione、Surfacie tractiones procedentibus, quales electroplating，Cubicula quadrata Carbona effectus aspicientes diversos constituere potest，Meet the aesthetic requirements of the building。
Mechanical manufacturing field
Mechanical structural components：In mechanical manufacturing，Cubiculae quadratesque Carbon steel usus sunt ut diversas structural componentes mechanicales fabricarent，Like equipment bracket、workbenches、Conveyor frame, etc。Haec componentes structural oportet resistere quidam cargam et vibrationibus，Exalta fortitudo et bona fortitudo tubarum quadraticum carbonium confortare potest。
automobilis：Carbon steel square tubas are also used for some non critical components in automotive manufacturing，Like the body frame、Chassis support, etc.。Suficiente fortitudo et stabilitate possit，Simultaneously reducing manufacturing costs。
Bridge construction field
Componentes pontis：In ponte aedificatione，Cubica quadrata Carbona steela ad fabricandum torrentes pontes potest、Bridge deck support、Components such as railings。Exalta fortitudo et bona fatiga resistentia tubarum quadraticum carbonium potest eis resistere cargas pontarum et varias pressiones in longo tempore uso。
Furniture manufacturing field
Metalis mobilis：Cubicula quadrata Carbona mobiles metalla fabricare potest，Like an office desk、filiing cabinet、Display racks, etc。Satis fortitudo et stabilitate habet，At the same time, different appearance effects can be achieved through surface treatment processes，Meet the aesthetic and practical requirements of furniture。
quinque、Selection precautions
Selection Materiale
Select appropriate carbon steel materials based on the usage environment and load requirements。ex exemplo，For structural components that need to resist large loads，Fortitudo maxima fertilis elegiturQ355acidus carbonis；For general purpose structural components，Q235Carbon steel est electus economicus。
precision dimensionala
Assecurate quia accuractia dimensionala tubae quadratis carbon quadraticum conformetur。Excessive dimensional deviation can affect the assembly accuracy and stability of the structure。ex exemplo，In aedificiis structurae steeli，deviatio longitudinis lateris et densitatis murorum tubae quadraticorum intra mensuram pertinentem esse，Connexiones firmas inter componentes confirmare。

Selekte appropriate surface treatment method based on the usage environment。Si tubas quadratas in exterioris environamentibus usantur，Anti corrosion treatment such as painting or hot-dip galvanizing should be carried out，Corosionem resistentiam enhancere；Si in medio domus utilizat，Paintura Spray can be selected according to aesthetic requirements、Surfacie tractiones procedentibus, quales electroplating。
qualitatem benedictionis
Welding is one of the main methods for connecting carbon steel square tubes，Qualitate benedictionis directo efficit fortitudinem et stabilitatem strukturae。During the welding process，Utrum ferentiam et ferentiam procedentibus eligere debent，Configurare qualitatem et fortitudinem plagae。ex exemplo，When welding thick walled carbon steel square tubes square，Multi layer and multi pass welding process should be adopted，To ensure the uniformity and strength of the welded seam。
costa control
Quando tubae quadratesque carbonis electant，Factores costis etiam considere sunt。Different materiales、Differentia pretiosa tubarum quadraticum carbonium cum variis dimensionibus et manibus operationis superficiis significata est。At the premise of meeting the usage requirements，Cubiculae quadratis carbonis cum alta costa effectivitate quam posibile selecta sunt，Reducere costas inženierii。
