Stainless Steel Bar
Stainless Steel Round Bright Bar
Hot-rolled Stainless Steel Black Bar
- Q:How many roots are there in a standard ton of steel and how many meters are there in a steel bar?
- Generally, the length of steel bars is 6 meters, 9 meters, 12 meters, 6 meters, which is rarely seen on the construction site. A standard bundle is 2 tons.
- Q:What are the scientific names of round bar and screw steel?
- Steel: steel is commonly known as hot rolled ribbed bar. Ordinary hot rolled steel bars are made up of HRB and the minimum yield point of the brand.
- Q:Which steel wire is the same diameter as round steel more resistant to breaking?
- A wire rope is a flexible rope twisted with a plurality of strands or strands of fine steel wire. The wire rope is twisted by multi-layer steel wires and then twisted by a certain number of strands into a spiral rope at the center of the rope core. In material handling machinery, for lifting, traction, tensioning and loading purposes. The wire rope has the advantages of high strength, light weight, stable work, easy breaking and whole breaking, and reliable work.
- Q:What's the difference between round steel and other steel bars?
- Different appearance, round steel appearance garden, no grain without rib, other steel surface has carved or ribbed. This causes the round bar and concrete bonding force is small, and other steel and concrete bonding force
- Q:What is galvanized round bar?
- A cylindrical bar of iron or steel bar that crosses a layer of zinc on its surface.
- Q:Why is the round bar bent?
- Round steel with hooks the aim is to increase the bond between concrete and prevent the component in the tension will be reinforced. Therefore, round bars should be 180 degrees of hook, should set up 90 degree hook ribbed bar.
- Q:Round bars and ribbed stirrups are much better
- Hot rolled ribbed steel bar with high strength, suitable for large component high-rise buildings under gravity loads, but also because of its surface shape can provide grip and end without hook, the corresponding anchorage length is short, the material.
- 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.
- Q:Weight algorithm of round steel
- Round steel weight = density * volume = density * base area * length of round bar.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:The diameter of 20 solid round steel bend into a circle, what machine bending?
- Hydraulic steel bar cutting and bending machineThe hydraulic steel bar cutting and bending machine is a dual-purpose machine which uses hydraulic technology to cut and bend steel bars. It has high automation and convenient operation.Structure: hydraulic type steel bar cutting and bending machine mainly consists of hydraulic transmission system, cutting mechanism, stubborn mechanism, engine, airframe and so on.Working principle: an electric motor drives two sets of plunger hydraulic pumps, one group pushes off the piston, and the other drives the rotary hydraulic cylinder to drive the rotary working disc to rotate.Cut off the working principle of mechanism in cutting piston is arranged in the middle column and the center of the valve spring, in turn, due to the action of the spring, the middle hole make the center column left valve hydraulic cylinder, high pressure oil is also from the eccentric shaft road to tank. In the cut, a human powered piston, the center hole center column valve blocked the hydraulic cylinder, the plunger pump to the hydraulic cylinder through high pressure oil into the oil valve, high pressure to push the piston movement, the piston drives the cutter to cut tendons. At this point, the thrust of the pressure spring is greater than the pressure in the hydraulic cylinder, the valve will return to its original position, and the hydraulic oil will flow along the oil channel of the central oil hole back into the tank. The return stroke of the piston is achieved by the rebound force of the plate spring.
