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 hot and cold rolled steel plate? How to distinguish? What high hardness? Which will produce noisy eye?
By definition, ingot or billet is difficult to deform under normal temperature, easy processing, generally heated to 1100 to 1250 DEG C for rolling, the rolling process of hot rolled steel rolling. Most are called hot method. But because the surface under high temperature steel is easy to produce iron oxide, the surface roughness of hot rolled steel, size fluctuation so large, smooth surface, precise size, good mechanical properties of the hot rolled steel, semi-finished or finished products and raw materials for the production of cold rolling method. Under normal temperature, generally understood as cold, from the metal science point of view, the boundaries of cold rolling and hot rolling should be differentiated by the recrystallization temperature is lower than rolling recrystallization. The temperature is higher than the recrystallization temperature of cold rolling, rolling for hot rolled steel. The recrystallization temperature is 450 ~ 600 degrees. The difference: the simple point that 1, cold rolled plate surface has a certain gloss hand feels smooth, Similar to that used for drinking water is very common, such as hot rolled.2 steel cup without pickling treatment, is on the market and many are similar to ordinary steel plate surface, rusty surface is red, the surface of the rusty purple black (iron oxide).The performance advantages of cold rolled plate and strip is: 1, high precision, cold rolled strip thickness not more than 0.01~0.03mm.2, thinner, cold rolled steel strip rolling thickness 0.001mm hot rolling; now the thin can reach 0.78mm.3, the surface quality is more superior, cold rolled steel plate can even produce mirror surface; and the surface of hot rolled plate there are defects such as pitting of iron oxide,.4, cold rolled plate can be adjusted according to the running properties such as tensile strength and technological properties such as stamping performance requirements of the user.
Q:What is the aging property of steel plates?
The aging of steel plate is usually due to the diffusion of carbon atoms and nitrogen atoms in the lattice, forming interstitial atoms, which leads to the solid solution strengthening of the steel plate.
Q:How much is 2 millimeters per square meter?
With the development of science and technology and industry, put forward higher requirements on the materials, such as high strength, high temperature, high pressure, low temperature, corrosion resistance, wear and other special physical and chemical properties, carbon steel has not fully meet the requirements.
Q:What's the difference between a spray plate and a colored steel plate?
Color steel plate, material without zinc flower leveling, hot galvanized steel coil and zinc alloy coating, steel coil and other good substrate;
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 swelling, water stop, rubber water stop and water stop steel plate are compared between the three:After using the water stopping strip (water stopping steel plate and water stop bar), the water can be prevented from soaking through the concrete, and the double protection function of water proofing and water stopping can be realized.
Q:What is the electromagnetic steel plate in the generator?
Looks like in the game but did not listen to the words, said in real life. Not heard of steel sheet of motor core
Q:P355NL1 what kind of material is the steel plate?
Use: used in petroleum, chemical industry, power plant, boiler, for the production of reactor, heat exchanger, separator, tank, oil tank, liquefied gas, nuclear reactor pressure vessel, boiler, liquefied petroleum gas bottle, hydropower station high pressure pipes, turbine volute equipment and components.
Q:What is a fixed length steel plate?
Fixed length: it is a kind of commonly used steel specification, which means that the size of steel supplied is certain.
Q:What are the problems encountered in the construction of steel sheet piles? How to deal with
Based on the soft, sometimes the construction was adopted into the adjacent pile phenomenon, measures is the number of adjacent piles are welded together, and in the application of play pile connected locking coated with butter and other lubricants to reduce resistance
