Q:Measures to prevent cold rolling of packaged cold rolled steel coils? Who can give some professional opinions oh?
Cold rolled steel coils are generally sprayed antirust oil, according to user requirements, light, medium, heavy oil 3 types. Nevertheless, if the oil is volatile or in a humid environment, the steel plate comes into contact with the water for a period of time, indicating that it is beginning to rust.
Q:What's the difference between hot rolled coil and hot-rolled carbon thin steel coil?
Hot rolled coil is used for continuous casting slab or as raw material, after reheating furnace heating, descaling into the roughing mill of high pressure water, roughing material by cutting head, tail, and then enter the finishing mill, the implementation of the computer controlled rolling, after finishing through the laminar cooling (computer controlled cooling rate and coiling) reel, a straight hair volume. Hair straightenerrollhead, tail tongue shapeand thefishtail shape, thickness, width of poor accuracy, edgehaswavy, folding, tower and other defects. The volume is heavy. (general management industry likes to use. )
Q:In the warehouse management system of steel coil
The warehouse is set to be required under the factories and production equipment and manpower planning, reasonable layout; to strengthen the internal economic responsibility system, scientific division, forming material export management assurance system; the service must implement the work quality standard > standardization, application of modern management technology and the ABC classification method, and constantly improve the level of warehouse management.
Q:Why cold rolled stainless steel sheet is lower than cold rolled stainless steel coil?
304 stainless steel coil 2.0*1219*C spot price 18 thousand and 100 / ton, general tolerance at about 1.8mm.Coil price * actual thickness / reference thickness = flat price1.81*1.8/2=16.29
Q:Why can't the coil weight be too low?
Because the steel coil is stored in warehouse stacking level, if the coil weight is too low, resulting in a single coil capacity is reduced, so that the steel roll easily crushed and deformed;
Q:Can cold rolled galvanized steel coils be acid washed after oxidation?
Hot rolling is made of slabs (mainly continuous billets) as raw materials. After heating, strips are made from roughing mills and finishing mills. From the last finishing mill stand out of the hot strip laminar cooling through to the set temperature, the coiling machine rolled strip steel roll cooled, according to the different needs of users with different finishing line (flat, straightening, transverse or longitudinal, inspection, weighing, packing and marking etc.) processing and become steel, flat steel product volume and slitting.
Q:What is the difference between a steel strip and a coil? The steel strip is flat steel, and the steel coil is made of steel.
A steel strip is also a coil, usually a narrow strip, also known as a steel strip. The volume is relatively wide. In addition, flat steel is usually hot-rolled out of long strip steel, fixed length 5 and 5.5,6 meters range, steel coil is Kaiping Chang 12501500, length 2.5 meters, 4 meters, 6 meters, ranging from steel plate
Q:Where are the coils and the steel plates used? Where did the steel plate come from?
Steel coil is a kind of steel plate, also known as coil.The coil, like toilet paper, can roll into a barrel. (describe not very appropriate)When the coil is used, it is necessary to use the Kaiping machine to expand into a flat plate.
Q:Where do I need hot galvanized steel coils and color coated rolls?
Hot galvanized steel coils and color coated rolls have light, beautiful and good corrosion resistance, and can be directly machinedThe construction industry, shipbuilding, vehicle manufacturing, furniture and electrical industries provide a new type of raw materialThe utility model has the advantages of steel replacing wood, efficient construction, energy saving, pollution prevention and the like.
Q:What is the difference between cold rolled strip and cold rolled steel coil?
Cold rolled steel strip: the width is below 900mm! Cold rolled steel coil: the width is above 1000mm! Materials and purposes are not very different, basically the same!
