Q:What is the tensile strength of round steel bars of diameter 28?
Round steel is a solid strip of steel whose cross section is round. Its specifications are expressed in diameter, in units of millimeters (mm), such as "50mm", which means a diameter of 50 millimeters of round steel.
Q:How is the copper wire and galvanized round steel connected during the construction of the lightning protection device?
Copper wire and galvanized steel bars can be directly welded together, do not pay attention to;Lightning protection device refers to the lightning receiver, the lead wire, grounding device, surge protector (SPD) and other connected conductor sum.
Q:40CrMo what is the round steel material?
High strength, high hardenability, good toughness, little deformation during quenching and high creep strength and lasting strength at high temperature.
Q:Round bars and ribbed stirrups are much better
The flexibility of hot rolled round steel bar is better than that of ribbed steel bar, and its fatigue stress amplitude is wide allowable. It is suitable for the components under dynamic load, as well as lifting rings, rings and lifting workpieces;
Q:What is the diameter deviation of 12 mm galvanized round bar?
It is widely used in hardware, building, automobile, shipbuilding, petrochemical, machinery, medicine, food, electricity, energy, aerospace and other architectural decoration. The most extensive machining of general machine parts, general rod type steel parts, CD pole, bolt, nut.
Q:The diameter of 20 solid round steel bend into a circle, what machine bending?
Worm and worm type steel bar benderStructure: worm and worm type steel bending machine, mainly each family, motor, transmission system, work mechanism (work disk, insert seat, gripper, shaft, etc.) and control system. A walking wheel is arranged under the frame for easy movement.Working principle: the power of the motor is rotated by the V belt pulley, the two straight gear and the worm gear rod, and then drives the working disk to rotate. The working disk usually has 9 shafts, the center hole is used to insert the central shaft, and the 8 hole seats around each have 6 holes, which are used to insert the retaining shaft. In order to move the reinforcing steel bar, two times of each work table is also provided with a feeding roller. When working, according to the bending shape of the steel bar, the square of the reinforcing steel bar is arranged between the central axis of the work disc and the corresponding forming shaft, and the inner side of the iron block is blocked. When the working disc is rotated, one end of the reinforcing bar is prevented from rotating by the iron blocking shaft, the central shaft position is fixed, and the forming shaft is rotated in an arc direction around the central shaft, and the reinforcing bar is bent.As a result of the specification, the bending diameter of the steel bar shall be no less than 2.5 times of the diameter of the steel bar when it is taken as a 180 degree bending hook. Therefore, the center shaft is also made into 16~100mm in 9 different specifications to meet the requirements of bending different diameter steel bars.
Q:Difference between forging and round steel
The advantages of a casting include an extensible length, a contracted cross section, a contracted length, an extended cross section, a variable length, and a variable cross section. The types of casting are free forging / hand forging, hot die forging / precision forging, top forging, roll forging and die forging.Forgings are not limited to round shapes.Round steel is a solid strip of steel whose cross section is round. The specifications are expressed in millimeters of diameter, such as "50", which means a round bar of 50 millimeters in diameter.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: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:Requirements for groove welding of grade 22mm round steel and manual arc welding
Chamfer or breach can also be used in grinding machine, notice groove surface cleaning with carbon or gas cutting, consider the parent material selection process, such as carbon will carburizing etc.
Q:Which is hard, round steel or screw steel?
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
