Q:Do I need to make the ring galvanized flat steel ground connection between the electric well and the distribution room?
There is also a dark, in the foundation of the house to consider the distribution of indoor total potential imbalance, in the basic reinforcement welding has been laid. Later, when installing the equipment, just connect in place
Q:What is the tensile force of the galvanized flat steel of 20*3?
According to "hot rolled flat steel size, shape, weight and allowable deviation", GB 704-88:Ordinary class allows upper deviation +0.3mm, lower deviation -0.5mm; higher allowed upper deviation +0.2mm, lower deviation -0.4mm, the upper deviation is not to think, do not exceed the next deviation is good.
Q:Earthing flat steel and earthing main line
Grounding flat ground belongs to the material, the grounding line belongs to the grounding line, grounding flat steel used for grounding grid, the grounding line is also one of the flat ground, for connecting the grounding grid, the grounding grid extends to the metal shell of the substation ground of all electrical equipment, and the grounding grid connected together.
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 many years can hot dip galvanized flat steel be used?
Experience has shown that the extent of atmospheric corrosion varies from region to region. The service life of hot-dip galvanized flat steel is different in different environments.
Q:The technological process of flat steel
The production process can be summarized as: pre leveling, finishing, straightening and leveling. Flat /a/b width 12-300mm, thickness 4-60mm, cross section is rectangular and with pure 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. Flat steel is divided into two kinds according to its shape: flat spring, flat steel and single side double slot spring flat steel. Hot rolled spring flat steel is mainly used in the manufacture of automobiles, tractors, railway transportation and other mechanical leaf springs.
Q:What is the rolling range of the micro cold rolled flat steel production line?
Flat steel, width 12-300mm, thickness 4-60mm, cross section is rectangular and with pure 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. Section steel is one of the four major steel products (plate, tube, mould, wire). According to the section shape, the section steel is divided into simple section steel and complex section steel (deformed steel). The former refers to the steel, round steel, flat steel, angle steel, six angle steel; the latter refers to the I-beam, channel steel, steel, steel, steel frame bending etc..
Q:Can roof strip be replaced with steel pipe instead of flat steel and round steel? Are there any examples of practical use?
Steel pipes can be used instead of flat steel or round steel, and some of the structures on the buildings are connected and grounded by using steel pipe handrails on the walls of their daughters.
Q:-40x4 hot galvanized flat steel, a water 1m, what do you mean?
Water is to protect the wall foundation using cement mortar width not less than 600 of a circle along the walls of the cement ground, if the main part of the project before the electrical engineering, auxiliary grounding length less than in bulk water, auxiliary grounding, ditching to destroy the water, so that the design requirements of 1 meters water is conducive to the construction of welding, may be more than one meter in order to facilitate their work.
Q:The distinction between flat steel and steel strip
Blue is to heat the steel or directly immersed in concentrated oxidizing solution in the air, material protection technology of oxide film on the surface of thin produce, also known as black. The blue steel parts can be carried out in the molten salt of sodium nitrite and sodium nitrate, can also be carried out at high temperature above 500 DEG C hot air and superheated steam, the more common is heating sodium nitrite in concentrated caustic soda. Solution composition, reaction time and the temperature of Bluing depends on steel matrix composition. Bluing film composition is magnetic iron oxide, the thickness of 0.5 to 1.5 microns, the color and the material composition and process conditions, a dark gray, dark blue, etc.. Bluing film separate corrosion resistance is poor, but the oil wax or paint varnish, corrosion resistance and friction resistance are improved. Blue, the workpiece has little effect on the quality of size and finish. It is commonly used in precision instruments, optical instruments, tools, hardness blocks and so on.
