Q:Galvanized steel flat welding occurs after the material itself crack.
Cold crack: a cold crack is a weld crack that occurs when the joint is cooled to a lower temperature. The causes are the quenching tendency, the residual stress, the diffusion hydrogen content of the weld metal and the heat affected zone.
Q:Are there any differences between flat iron and flat steel?
The steel and iron are carried out using redox reaction, but there is a great difference in the response object: iron is iron reduced, while steel is the excess carbon in pig iron and other impurities in the actual operation, so the two links are different.There are three main ways to make steel: converter, electric furnace and peace furnace. Among them, the converter steelmaking method is more common. We do not need to remember its specific operations (but only to lead to understanding), but attention should be paid to reactions such as ferric oxide, removal of magazines and deoxygenation. A large amount of brown vapor is produced during steelmaking, consisting of iron oxides, dust particles, and high concentrations of carbon monoxide, which must be purified.
Q:How to connect the base of the tower crane and the flat steel? How can it be welded and connected?
How to connect the base of the tower crane and the flat steel?:It can be punched on a flat iron and connected by screws and multiple copper wires
Q:What is the use of slitting flat steel?
Flat cut flat steel, also called fine shearing flat steel strip, can be used to produce iron, tools and mechanical parts, and is used as frame structures and escalators for buildings.
Q:What's the difference between stainless steel flat bar 304 and 316
316 stainless steel flat type is 316, the material is stainless steel. The stainless steel should be a bundle of delivery, the bundle passes, bundle length should be specified. Stainless steel flat is generally naked, delivery, transportation and storage are required to pay attention to moisture.
Q:What about the installation height of the socket and the height of the ground flat steel?
If the construction unit, design institute and contact Party A drawings or design change
Q:Where is the use of flat steel in electrical use?
The flat steel used in the project consists of two types: galvanized and non galvanized. Galvanized is mainly used in decorative materials and pipes, such as rings, hoop and so on;
Q:Please: hot galvanized flat steel and copper clad steel ground!
Compared with galvanized flat steel and other grounding materials, copper clad steel ground wire features: 1, corrosion resistance is better: no residual inside the bimetal, better corrosion resistance. The horizontal continuous casting process adopts high temperature melting, and the residue is calcined to overflow the copper surface, and can not be left in the copper clad steel conductor, so the corrosion phenomenon can not occur inside. 2 、 better electrical performance: the surface of oxygen free copper, good conductivity, the inner layer of high-quality carbon steel, skin effect principle, conductive, magnetic characteristics are excellent. The resistance is much lower than conventional materials such as steel, galvanized steel, etc. the surface layer is oxygen free copper.
Q:The function of ground lead out galvanized flat steel
Use and test, debug, you must use lead line.In accordance with the D501 specification, its cross section is not less than 4*40
Q:What is flat steel, please?
Flat, refers to the width 12-300mm, thickness 4-60mm, cross section is rectangular in shape and with a blunt edge of steel. Flat steel can be finished steel, or can be used as the blank of welded pipe and thin slab for laminated sheet rolling. Main application: flat steel is used as a material, used for making iron, tools and machinery parts, and used as frame structures and escalators for buildings.
