Q:How is the normalized steel plate produced?
Normalizing, also known as normalizing, is to heat the workpiece between 727 and 912 degrees Celsius. 40~60min, after a period of heat preservation, is removed from the furnace and cooled by air or by spray, spray, or blow cooling. Its purpose is to make grain refinement and carbide distribution homogenization, to remove the internal stress of materials.
Q:Why can iron and steel stick with glue?
Instead of ordinary glue, it is a new type of glue used to bind steel. It is made from synthetic resin as the main raw material.
Q:Why can steel HPB300, steel plate without Q300, steel structure manuscript review, but also continued the Q235, why not improve it?
Carbon steel according to the steel yield strength is divided into 5 grades: Q195, Q215, Q235, Q255 and Q275 of each grade because the quality is divided into A, B, C, D grade, with a maximum of four kinds, some only one; this is just plain carbon steel, the price is cheap, generally not heat treatment. Only quality carbon steel has the value of heat treatment.
Q:How thick is steel filing cabinet usually made of steel plates?
There are generally 0.5 or 0.6mm cold rolled plate, but you need to store items to determine the weight slightly (because the item is stored for a long time, the plates have a fatigue test), some manufacturers use 0.5mm to strengthen the bearing plate, the bottom can reach about 30KG, with the strengthening of and manufacturers not only the two section bending, bearing instead of added 0.5mm to strengthen the
Q:What does "rolled steel" mean?.
Generally refers to the thickness below 3, some enterprises have used rolling process, for example, 1.97 of the stainless steel materials market is difficult to buy, the enterprise will use 2 or 2.5 of the material rolling process processing, production of 1.97 thickness.
Q:What is a fixed length steel plate?
Such as steel plate, its fixed length is six meters, then it is 6 meters, the size will not be uneven. The standard size of the general steel plate is determined according to the national standard, such as 6 meters, 9 meters, etc..
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:Can 16Mn steel plate be used instead of Q345D steel plate?
If the use of Q345D instead of using 16Mn, that can be, but 16Mn instead of Q345D can not, and also can not buy 16Mn steel now, that is the old number, and the latest brand is Q345A
Q:The difference between steel edge sealing strip and steel plate putty water stop belt
The steel sealing strip is made of pure steel plate and can be divided into galvanized steel sheet, ordinary steel plate and stainless steel water stop belt.The steel plate putty water stop belt is covered with butyl rubber. The main material is a kind of rubber and plastic material with good aging resistance. It has a strong self adhesion, and it does not run in summer. Low temperature in winter, no brittle, and has excellent water, acid and alkali resistance and aging resistance, long service life, the product itself non-toxic, good environment. In order to withstand certain bending and pressure. There are 0.4 or 0.6mm steel plates in the center. The steel plate putty water stopping belt can provide reliable waterproof and anti-seepage function to the building joint. Steel plate putty water stop series products include various specifications and types of products, and can produce various types of steel sheet, putty, water stop belt according to user requirements, to meet the actual needs of the project.
Q:What is the width of carbon steel coil and the width of stainless steel coil, one is 1250 and the other is 1219?
A continuous rolling mill is put in billions of dollars, but this is the rolling mill, and there are many gold furnaces.
