Q:What is the difference between hard steel plate and soft steel plate?
Molding (Injection) refers to the process of heating and melting material from the high pressure into the mold cavity, after cooling and curing, to obtain forming products. This method is suitable for mass production of complicated parts, and it is one of the important processing methods. The injection molding process can be broadly divided into the following 6 stages: mold injection - pressure holding - cooling - mold opening - product removal, and the process can be repeated to produce products continuously.
Q:What is AO steel plate?
The locking plate is fixed to connect without bone friction, but rely entirely on the steel plate interlocking structure to achieve. The steel plate and the bone surface can leave the gap, to eliminate the adverse effects of contact with bone plate stress, greatly improve the blood supply and the growth of periosteum and recovery. Screw and plate angle fixed, plate and screw and the backbone form the stereo than ordinary AO plate fixation, locking plate fixation is more stable.
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:How much is 2 millimeters per square meter?
The performance of carbon steel mainly has the following deficiencies:(1) hardenability is low. Under normal circumstances, the maximum quenching diameter of carbon steel water quenching is only 10mm-20mm.(2) strength and yield strength are relatively low, such as the s of ordinary carbon steel Q235 is 235MPa, while that of low alloy structural steel 16Mn is 360MPa and above s. The sigma S / sigma B of steel 40 is only 0.43, much lower than that of alloy steel.(3) the stability of tempering tempering stability, carbon steel in quenching and tempering treatment, in order to ensure the high strength with the tempering temperature is lower, so the toughness of the steel is lower; in order to ensure good toughness, with high tempering temperature strength is low, the mechanical properties of carbon steel level is not high.(4) stainless steel can not meet the requirements of special performance. Carbon steel is often poor in oxidation resistance, corrosion resistance, heat resistance, low temperature resistance, wear resistance and special electromagnetic properties, and can not meet the needs of special performance.
Q:Stainless steel plate and steel welding
It is better to use argon arc welding or white steel welding rod, with electrode generally 3.2 or 2.5 can be, the color will change with some, wipe it will be good.
Q:How can steel plates with a thickness of 1MM be welded?
1mm steel plate is best made by spot welding or flash welding, for example, electrical welding will cause plate deformation
Q:What is the difference between the zinc plated color guide and the profiled steel sheet?
Because the original plate is very thin, the quality of the anticorrosive coating directly affects the service life of the profiled steel sheet. In order to meet the requirements of processing and rust prevention, the coated steel plate shall be examined in accordance with the relevant provisions. Under normal circumstances, thin steel plate can also be used according to the requirements, after pressing type, and then coated with anti rust paint, or use stainless steel sheet, the original plate.Profiled steel sheet used in industrial plants, housing panels, wall panels, in the absence of general insulation requirements, steel per square meter of about 5~11 kilograms. Insulation requirements, availability of mineral wool board, glass wool, foam and other insulation materials. The profiled steel plate and the concrete are combined into a composite floor board, and the wooden formwork can be omitted, and the utility model can be used as a load-bearing structure. At the same time to strengthen the binding force of steel sheet and concrete, should be pre welding studs in steel plate or pressing two-way stiffener
Q:Q235 is hot rolled steel or cold rolled steel?
Hot rolling and cold drawing is the difference of the production process of hot rolling is processed at high temperature, does not change the structure and properties of metal at high temperature, cold drawn round will be perforated, then in tube processing machine in the cold drawing, no tempering condition, this process will affect the crystal structure of metals. In general, better than the mechanical properties of cold rolled steel, after heat treatment, the tensile and yield strength, plasticity and toughness will be improved, in addition, heat treatment can eliminate the residual stress, and the cold may be because in the process of the steel yield the non-uniform deformation. The residual stress produced, the residual stress has great influence on the stability of.
Q:What's the density of the 0.5 color steel plate?
We often see the color steel plate refers to the processing of sheet metal, the thickness of about 50~100mm, it is composed of the middle filler and two sides of color steel plate. Among them, the color plate thickness of 0.4mm, 0.5mm, 0.6mm and other different thickness, the middle layer can be polyurethane, rock wool or foam plastic. Because of the special profiles, the construction of the building with colored steel plate is very fast (such as the Xiaotangshan hospital in SARS), but the strength is low. The substrate of the color coated steel plate is a cold rolled substrate, a hot-dip galvanized substrate and an electro galvanized substrate. The coating types can be divided into polyester, silicon modified polyester, vinylidene fluoride and two plastic sol. The surface state of color coated steel sheet can be divided into coated plate, embossed plate and printed board.
Q:What are the rental costs for steel sheet piles?
According to the different processing technology, it can be divided into hot rolled / stretched steel sheet pile and cold rolled steel sheet pile. Now, due to the production conditions and scale constraints, hot rolled steel sheet pile has no production line in China, and the rolled steel sheet piles used in China are all from abroad.
