Usage and Applications of Round Bar

1. Chinese standard steel bar is often used where large amounts of steel need to be formed, for example as structural steel.

2. And we can use this kind of product on the performance of the mechanical parts if the demand is not very high.

3. Steel round bar is used in construction and a large number of architectural and engineering structures.

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.
Q:What is the difference between steel and flat steel, round steel and steel?
In fact, for the processing of raw materials are the same, is used when the roller rolling pressure is not the same, there are many different types of tooth roller shaft, can produce different steel, the steel section is square, round cross section is round
Q:How many tons of pressure can the round steel of 70 inches bear?
As the diameter of about 11.5 cm diameter 180 cm long in the middle of the force which kind of force will be smaller if the curvature is hollow capability hollow wall thickness to achieve much greater strength than solid to do not understand what the best please say a little more thank you good answer is a plus
Q:What's the difference between round steel and carbon bound steel?
The composition is different, round steel (grade a steel) belongs to ordinary low carbon steel, carbon tie steel is mostly alloy steel.
Q:45# what are the main rounds for?
45# round bars are divided into three kinds: 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 kind of steel bars are used in general civil buildings?
Steel is the HRB335, the diameter of 12 to 22, 25, 28, even 32, and then rough generally appear in the mass concrete construction, not commonly used, generally below 25 is commonly used in masonry structure in rural low level below 16 is most commonly used. Used as beams, columns, main bars and stand bars, etc.
Q:Special steel bar steel products used to do what
But the red hardness difference of this kind of steel, that is, when the working temperature is greater than 250 degrees, the hardness and wear resistance of steel will decline rapidly, and lose their ability to work. In addition, carbon tool steels, such as those made of larger parts, are difficult to harden and easy to produce
Q:How is the copper wire and galvanized round steel connected during the construction of the lightning protection device?
Grounding device is an important component of lightning protection device. The earthing device releases the lightning current to the earth, and limits the lightning protection device to the ground voltage not too high. In addition to the independent lightning rod, the grounding device can be shared with other grounding devices on the premise that the grounding resistance meets the requirements.
Q:How about tempering No. 45 round bar?
Quenched and tempered steel has two major categories: carbon quenched and tempered steel and alloy quenched and tempered steel. Carbon steel or alloy steel, the control of carbon content is relatively strict. If the carbon content is too high, after quenching and tempering the strength of the workpiece is high, but the toughness is not enough, such as carbon content is too low, toughness and lack of strength. In order to make the quenched and tempered parts get good comprehensive performance, the total carbon content is controlled at 0.30~0.50%.
Q:Lightning protection earthing zinc plating flat iron and round steel welding method, need to flat iron wrapped in round steel outside welding?
The flat steel is not required to be wrapped outside the round bar, and the round steel can be directly welded on the flat steel, and the welding joint area can not be smaller than round steel or flat steel, and the section is a cross section
