Q:How to distinguish between cold plating and hot rolled round steel?
First of all, the difference between the process is: hot-dip galvanizing is to remove the workpiece, oil, pickling, dipping, drying, immersed in dissolved zinc liquid, a certain time, can be put forward.
Q:Specifications of the same kind of galvanized round bar more expensive than round steel?
The general market price than ordinary steel galvanized steel bar of your 2000-3000 dollars per ton, according to your purchase requirements, price range of relatively large fluctuations, such as whether to open a formal invoice, transport distance, purchase quantity, relationship with your level of economic development, the developed area of fierce market competition, the price is relatively low. The prices and prices of large factories and small factories are not the same. The prices of big factories are generally high, and the prices of small factories are low.
Q:How many positive and negative tolerances are allowed for round steel GB?
Because of the deviation of cold rolled steel plate and hot rolled steel plate is not the same as the.5mm hot rolling strip is usually made of steel plate shear, the thickness deviation according to the different width and different. But the minimum of plus or minus 0.19, the highest of plus or minus 0.29 this standard applies to the diameter of 5.5mm ~ 250mm hot rolled round and length of hot-rolled square steel 5.5mm ~ 200mm.
Q:What is the mechanical properties of No. 40 round bar?
40# stands for steel grades, round bars for steel profiles, mechanical properties for steels, tensile strength, yield point, (cattle / mm, 2) elongation, shrinkage (%), impact energy, Ak (coke), state, hardness, HB<
Q:The diameter of 20 solid round steel bend into a circle, what machine bending?
Gear type steel bar benderStructure: gear type steel bending machine mainly consists of several motors, gear reducer, work mechanism and electrical control system. It changed the traditional worm gear drive, and increased the angle automatic control mechanism and brake device.Operation principle: the gear type steel bar bender is driven by a motor with braking, which drives the working disc to rotate. The two inserting seats on the left and right of the working mechanism can be adjusted by the hand wheel without bending, and can be bent and bent with different specifications of the steel bar. The angle is controlled by several different institutions and primary angle limit pin with each other and realize. When the steel bar is bent to the preselected angle, the limit pin touches the travel switch, causes the motor to stop and reverse, recover to the original position, and complete the bending process of the steel bar. In addition, the electric control system also has the characteristics of inching, automatic state, two-way control, instantaneous braking, emergency stop, rapid system short circuit protection, motor overheat protection, etc..
Q:What is the difference between cast iron and round steel?
Cast iron is composed of iron ore by crushing and grinding into powder, into the furnace after high temperature calcination into liquid (commonly known as iron) and then poured into the special mould after cooling into ingot is also called billet or iron, iron is the main component of alloy is composed of iron, carbon and silicon.
Q:What's the difference between round steel and carbon bound steel?
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.High quality carbon structural steel short for carbon tie steel. Specifically, its carbon content is less than 0.08%. Compared with plain carbon steel, its quality is superior, it has strict chemical composition, and requires the guarantee of mechanical properties, high quality carbon structural steel with low impurity content such as phosphorus and sulfur.
Q:What is round steel?
More than 25 mm round steel, mainly used in the manufacture of mechanical parts or between round steel and other steel seamless steel tube blank: 1 is not the same, round shape light round, no pattern without ribs, other steel surface appearance is engraved or ribbed. Bond thus causing steel and concrete, and the bond strength.2 other components of steel and concrete are not the same, round (a steel) belongs to the ordinary low carbon steel, alloy steel reinforced many other.3 strength is not the same. The low strength steel, and other steel with high strength, the diameter of the same size as compared with other steel, round steel can bear the pulling force than other small steel however, plastic steel reinforced bar is stronger than the other, there is a large deformation in the break before, while the other bars in the break before the deformation is much smaller.
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 to solid
Q:What kind of steel bars are used in general civil buildings?
In the general construction of commonly used hot rolled round bar (commonly known as round steel), hot rolled ribbed steel bars (commonly known as steel), the two most widely used steel. Identified as HPB235, the diameter of 6.5, 8, 10, 12, and then rough is not commonly used, and in the 6.5 and 8 most as commonly used, used as column, main reinforcement and stirrups and plate reinforced beam distribution.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.
