Q:What are the characteristics of hot-rolled steel coils and cold rolled steel coils? What loading and unloading tools should be used? What items should be paid attention to?
When placing materials to roll on both sides of the main pad wood pallets, prevent rolling back and forth. In addition the floor should be thickened, cannot have uneven or debris, because the line of steel coils when gravity concentrated in contact with the ground floor, there is a fracture easily, debris, easy to leave the indentation in the steel roll.
Q:What's the difference between hot rolled coil and hot-rolled carbon thin steel coil?
The difference between hot rolled primary and hot-rolled carbon thin steel coils is that they include carbon steel rolls and low alloy steel coils.
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:What is the maximum width of galvanized steel strip, please? The galvanized coat is 275, and how long is one coil?
But this kind of steel coil is not well processed in the market. At the beginning of Wuhan, several processing plants are good at processing, and other processing plants usually process 1850 at most.
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:What is the accuracy of steel tape inspection?
The precision is the minimum scale of this measuring tool. The minimum scale of the steel tape measure is millimeters, and the data below is the reading data,
Q:Cold rolled steel coil steel, what is the difference?
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, its strength is not very high, but the ductility and weldability is good, the appearance of color is not bright, easy to corrosion, because the price is cheap, the majority of enterprises in order to reduce the cost, so the more commonly used.
Q:A roll of 1 meters wide color steel roll about how many tons?
In general, between 3.5 and 5 tons. Our company uses 0.17*1000 white color steel roll. The weight is usually around 4.5 tons. Different manufacturers will have different sealing rolls.
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,
Q:How are steel tape measures installed?
That's the tape measure. There's a small card with no card in the middle of the screw! So it can't be retracted automatically! The solution is to wrap the open tape to the end!
