Q:Cold rolled steel coil steel, what is the difference?
Steel rolling process is different from the steel produced naturally different!
Q:In the warehouse management system of steel coil
Warehouse is an important component of enterprise material supply system. It is also the tache of enterprise material circulation and storage, and it also undertakes many functions of material management. Its main tasks are to keep the stock well, to be accurate, to be of good quality, to ensure safety, to prompt the people, to produce, to be considerate, to reduce costs, and to speed up capital turnover.
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:Measures to prevent cold rolling of packaged cold rolled steel coils? Who can give some professional opinions oh?
In order to prevent rusting in the process of storage or transportation of steel roll, steel mills generally take the following packing: inner gas antirust paper wrapped with tape wrapped in plastic film sealing, intermediate, involute cardboard seal lining, cardboard corner, with iron and steel outer package corner protector, strapping fixed. If the inner package seal, so the steel coil is sank into the water, will not rust out.
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:Aluminum alloy rolling doors and color steel shutter door that good
The material and structure design Aluminum Alloy rolling shutter door out of the ordinary, can effectively prevent glare and ultraviolet radiation, sunlight greenhouse effect on indoor has completely solved, applicable to all kinds of changes in climate and weather, has a long-term protective effect on indoor environment, tests show that the shutter doors and windows to keep out sunshine rate to 100%, the the rate can reach more than 95% block temperature.
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:Is a steel plate the same as a steel coil?
Generally speaking, they can be used interchangeably, and the purchase price of the plate is slightly cheaper.
Q:Why is the steel tape tape head not fixed?
In this way, no matter how you measure, always be measured, from the ruler of the "0" bit began.The fixed ruler does not take this action when it is taken, which directly results in the thickness of the steel sheet that needs to be added or lowered to your readings;Activity design is designed to reduce error, and this is an advanced approach;
Q:What is the difference between cold rolled strip and cold rolled steel coil?
A simple point is the difference between a strip and a volume. Strip is the flat strip of cold rolling, which is further processed on the basis of flat strip and rolled into thinner and can be rolled up,
