Q:What are square steel, rectangular tube, angle steel or light steel?
Light steel is also a relatively vague term, generally can have two kinds of understanding. One is the current "code for design of steel structures" (GBJ 17-88) in the eleventh chapter "bar, small angle light steel structure", refers to the use of steel and light steel structure is less than L45*4 and L56*36*4 angle steel production, mainly in the lack of time for small steel structure manufacturing of reinforced concrete structure should not be used, has been basically not used, so the revised code for design of steel structures has been basically removed this tendency. The other is the "Regulations" technology of steel structure of light-weight buildings with gabled frames with light roof and wall light (also has the condition to use the masonry wall) single portal frame structure, the light here mainly refers to the enclosure is made of light material. Since the former has been cancelled soon, the meaning of "light steel" mainly refers to the latter
Q:On the market, 8mm Round Bar is not 9 meters a root? How much does it weigh about 300 meters? How much does it cost?
Method of calculating reinforcement weight, unit length, weightD*d*0.00617= (6 in 7)For example, 8mm steel 8*8*0.00617=0.39488 take 0.395Round steel and rib are calculated the same wayRound bar 8 is rolled up, usually between 2~4 tonsYou'll have to straighten it up, straighten it up, and straighten it up
Q:The diameter of 20 solid round steel bend into a circle, what machine bending?
Or a bar bending machine machine, the installation of a 20cm diameter on the rotating die on the line, available 20mm manual welding steel die making.
Q:Will the theoretical weight of thread steel and round steel be the same?
The rebar is a kind of small section steel, mainly used for the skeleton of reinforced concrete construction members. In use, some mechanical strength, bending deformation property and welding performance are required. The raw steel billet for the production of threaded steel is carbon structural steel or low alloy structural steel which is treated by calm melting, and the finished steel bar is delivered in hot rolling forming, normalizing or hot rolling state.
Q:What are the scientific names of round bar and screw steel?
Round steel and thread steel are just popular terms for steel reinforcement in construction. In the construction, steel by HPB235, belonging to the carbon steel, steel is Q235; steel by HRBxxx, the steel is the most commonly used HRB335 and HRB400, they are called hot rolled alloy steel, cold steel lines, is heat treated in a bar.
Q:Grade 1 steel is round steel, grade two steel is ribbed thread steel. Are the weight of the two units the same?
Grade two steel is ribbed steel, but the average diameter is calculated. The chemical composition of grade steel and grade two steel is different, but the density of them is the same. Therefore, the unit weight of grade 1 steel and grade two steel is the same.
Q:What is the difference between a circle and round steel continuous casting
The first two density is not the same, the round billet continuous casting billet is molten steel into round billet crystallizer, after two cold water cooling, solidification formation, density is small; bar is formed by the billet or round billet rolled steel products, good density, better mechanical properties than the same size of billet. Second, round billet is the raw material for steel rolling, and the bar is the final product sold as steel.
Q:What is hot rolling? What is called forging?
Forging is a method of processing wool embryos by plastic deformation. They are also classified as cold forging and hot forging
Q:Is steel bar round wire? What's the difference? What are the main applications of wire rod?
Round bar is divided into three parts: hot rolling, forging and cold drawing. Standard Specification for hot rolled round steel is 5.5-250 mm. Of them: 5.5-25 mm small round bars are mostly supplied by straight strips. They are used as reinforcing bars, bolts and various mechanical parts. They are more than 25 millimeters of round steel. They are mainly used in the manufacture of mechanical parts or seamless steel tube billets.
Q:Q235 and mechanical properties of hot rolled steel cold drawn steel have what difference, Q235 hot rolled steel with 12 combined shearing machine has a number of very hard, the damage of the blades, why
The difference between hot rolled steel and cold rolled steelHot rolled steel contains slightly higher carbon content than cold rolled steel. The density is the same in cases where the composition is not constant. But if the composition is different, such as stainless steel, whether cold-rolled or hot rolled steel, the density is about 7.9g/cm3. Specific depends on the ingredients, hot-rolled steel plate is only better ductility, steel is also under pressure.Hot-rolled steel is divided into structural steel, low carbon steel, welding bottle steel, and then according to various kinds of steel to find the steel that you need, check the density and composition of the specific steel.Hot rolled steel is low in hardness, easy to process and good in ductility.
