Q:Bathroom washing machine, galvanized steel and color steel which good?
Infiltration of zinc is the function of zinc atoms to the steel parts, the steel plate has undergone a qualitative change, even if it does not scratch Yi Shengxiu
Q:What are the driving methods for steel sheet piles?
Mechanical hand general construction pile length of less than 12m steel pile; more than 12m length generally use crawler crane combined with vibration hammer construction, if the surrounding environment is sensitive to vibration, can use Japanese static pressure pile driving machine construction. The vibration hammer: DZ40 DZ45DZ60 DZ90 DZJ120; ordinary steel sheet pile, DZ60 type vibrating hammer.
Q:What's the difference between the three kinds of pickling plate, cold rolled plate and hot rolled plate?
Acid board: that is, the hot rolled plate passes the phosphorus removal (the rust, residue, etc.) produced in the process of hot rolling, and so on, the pickling surface is used to obtain the steel plate which is better than the hot rolling surface
Q:Is color steel plate the same as color steel tile?
Tile color steel tile is used for color coated steel plate, pressure plate and the roller of cold bending into various wave types, it is suitable for industrial and civil buildings, warehouses, special buildings, large-span steel structure house roof, walls and wall decoration, has the characteristics of light weight, high strength, color rich, convenient construction, affluence earthquake, fire, rain, long service life, maintenance free, have been widely applied.
Q:What type of welding rod is used for steel Q245R and Q235B material?
If the welding weld is non pressure parts, you can use the CO2 gas shielded arc welding, using 1.2 or 1.6 ER50-6 diameter wire welding, weld spatter if you need better or less, recommend the use of Ar:CO2 mixed gas 8:2 welding.
Q:Q235 is hot rolled steel or cold rolled steel?
Hot rolling and cold rolling are forming processes of profiled steel or sheet steel. They have a great influence on the microstructure and properties of steels. Steel is rolled mainly by hot rolling, and cold rolled only for the manufacture of small sections of steel and thin plates.The advantage of hot rolling is that it can destroy the casting structure of steel ingot, refine the grain of steel, and eliminate the defects of microstructure, so that the steel structure is compact and the mechanical properties are improved. This improvement is mainly reflected along the rolling direction, so that steel is no longer a certain extent, isotropic body; casting formed when bubbles, cracks and loose, can also be welded under high temperature and pressure.
Q:What is muotileaved spring? What is the little leaf spring?
Leaves: by the middle thick and thin steel sheet at both ends of the superposition of equal width. The plate section changes little leaf spring, from the middle to both ends of the cross section is gradually different, therefore the rolling process is more complex, the price is expensive than multi leaf spring. Compared with less leaf spring leaf spring, in the same stiffness (i.e. the same carrying capacity) under the condition of less than the spring leaf light is approximately 50%, reducing fuel consumption, increased ride comfort. And between the little leaf spring monolithic contact, reduces the relative friction and vibration, the ride comfort is increased.
Q:What is called steel plate sanding process?
Sand blasting can remove the oxide surface and floating rust on the surface of steel plate. It is a good process before anticorrosion painting. Sandblasting of other components may be more useful for pre coating treatment.
Q:What's the effect of water stopping between steel plate and water stop strip? What's the difference between the process and the sealing process?
Water stopping principle: the water stop bar is expanded by water absorption and then squeezed with concrete to stop the void.Construction technology: the stop bar is square long strip, and parallel lap method is adopted when connecting. No break point can be left in the middle. Construction units in order to facilitate, often like to use the water bar, concrete pouring in the completion of the pressure on the wall concrete pouring surface, or reserved groove, two times mosaic.Good and bad analysis: simple construction, less investment, relatively economic. But there is no water stopping effect and the water stopping steel plate is good. There are many unforeseen problems during the construction process. One is that the reinforcing bars are not close enough to be laid. Two is the time is too long, moisture absorption expansion, the impact of the effect, especially in the rainy season, air humidity, rainfall, water retention is worse. Three construction joints are not smooth, poor contact. Usually, this method is not ideal for stopping water. For example, when the water stop bar is installed, the retaining of the groove is too large to be fixed effectively; the small inlay is not in place; when the concrete is poured, the utility model is easy to shift under the action of the concrete buoyancy.
Q:What's the difference between steel plate 20 and Q235 steel plate?
In the normalizing state of No. 20 steel, the yield point is 245MPa, the elongation is >25%, the quenched and tempered state, the yield point is 280MPa, and the elongation is >22%. Widely used in the production of small, high load toughness requirements of parts, such as rod, heavy and general machinery in forging the sleeve, fixture and liner, general machinery and automobiles and tractors in small parts of carburizing, cyaniding.
