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:What is the difference between strip steel and round steel? Where are they mainly used?
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 which: 5.5-25 mm small round bars are mostly supplied by straight strips. They are used as reinforcing bars, bolts and various mechanical parts. Round bars larger than 25 millimeters are used mainly for making mechanical parts or for seamless steel tubes.Mainly used in the manufacture of various tools, cutting tools, moulds and tools (see tool steel), but also a large number of used in the manufacture of various mechanical parts.
Q:Lightning protection earthing zinc plating flat iron and round steel welding method, need to flat iron wrapped in round steel outside welding?
Unwanted。 The round bar shall be welded directly on flat steel, requiring both sides of the round bar to be welded, and the length of lap welding shall be 6 times of the diameter of round steel.
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:Is the shear wall concealed column stirrup steel or round steel?
Specify the construction drawing is HPB300 is hot rolled round bar, that is HRB335, HRB400 is the hot rolled ribbed bar. Don't call thread steel, this name has long been abandoned. Simple, light marked wall column reinforcement detail construction drawing on the diameter and spacing is not encrypted, what non encrypted area, like the dense spacing.
Q:What's the difference between round steel and screw steel? Which is cheaper than steel on the market these days?
Steel is known as hot rolled ribbed bar. The specification of rebar is large, and it belongs to small section steel. It is mainly used for the skeleton of reinforced concrete construction component. Generally required in the use of a certain mechanical strength, bending deformation properties and welding process performance.
Q:What kind of steel is used for anchor bolt material? What's the quality of anchor bolt material?
The anchor bolt can be divided into fixed anchor bolt, movable anchor bolt, expansion anchor, anchor bolt and bond anchor bolt. According to the different shapes, they are divided into: L type embedded bolt, 9 type embedded bolt, U type embedded bolt, welding pre embedded bolt, bottom plate embedded bolt
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: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:Is steel bar round wire? What's the difference? What are the main applications of wire rod?
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.
