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:Steel coil from vertical to horizontal, what sling needs?
The sling has little effect, but it is easy to damage the surface of rolled steel.
Q:What brand steel tapes are of good quality?
Personal feeling is also good for the Great Wall Seiko tape, upstairs several estimates are the production of steel tape manufacturers, of course, that their goods well. Our unit now buy all the Great Wall Seiko goods, said the tape is good, not because it is so durable
Q:Why is the steel tape tape head not fixed?
There are better tape measures, heads and magnets. For measuring steel objects, one can operate long distances.
Q:What is the accuracy of steel tape inspection?
For example, you measure the length of a steel tape by 12.5 millimeters, 12 of which can be measured on a steel tape measure, and 0.5 you read. So the accuracy is millimeters.
Q:Several reading methods of steel tape measure
Indirect reading methodIn some parts of the steel tape can not be used directly, can use the ruler or ruler, the zero alignment measurement, ruler and measurement direction; steel tape measure distance to a whole scale ruler or ruler, with more than a long reading amount. (3).Some errors in measuring steel tape
Q:How can the outer diameter and weight of steel coil be converted?
Of course, the calculation is relatively coarse, and the volume has a lot to do with the tension.
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 a steel strip of relative range, and can be called a steel strip when the width is less than 1000.
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!
