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
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:Why cold rolled stainless steel sheet is lower than cold rolled stainless steel coil?
Hello! The reason is: 1. cold rolled flat plate is Kaiping;2. cold-rolled plates are negative tolerances.
Q:How to solve steel plate storage
The warehouse temperature should be constant, prevent the occurrence of condensation, a horizontal steel coil to pile up, forced to pile up, in contact with each other at the coil not binding belt lock, steel roll room felt material, narrow roll on wide roll, roll on roll light. In order to facilitate the lifting, the steel coil and the wall should be kept a certain distance.
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:The difference between aluminized color steel roll and ordinary color steel roll
Substrate selection: AZ150 (aluminum zinc content 150g/m2); G345A high strength galvanized steel sheet (55% aluminum, 43% zinc and 1.6% silicon) corrosion resistance data: 5%NaCL 35 DEG C, 1000Hrs, Field good, Scribe, No, Blister, 2mm belowQ.U.V: 2000hrs, MAX.2 color, light to keep the rate above 90%, the above data show that aluminum zinc coated board (AZ150, G345A, PVDF) is very suitable for the extreme environment of buildings or other facilities, highly corrosion resistance and weather resistance, and the major steel plate can ensure the service life of 20 years. In addition, high strength steel has been widely used abroad, and it has good economic performance, and it is also the domestic development trend.
Q:Several reading methods of steel tape measure
Direct reading method when measuring the steel tape zero scale alignment measurement starting point, proper tension (stretching force with steel tape tension or tension on the calibration ruler identification shall prevail, with the spring balance measure), direct reading measurement end point corresponding to the scale scale.
Q:Cold rolled steel coil steel, what is the difference?
Cold: hot rolled steel coil as raw material by pickling descaling after cold rolling, the finished rolling hard volumes, due to continuous deformation caused by cold hardening the volume rolling hard strength, hardness, toughness index rise decline, so the stamping performance will deteriorate, only for a simple deformation of parts. Rolled hard rolls can be used as raw material for hot galvanizing plants. Because the hot galvanizing units are equipped with annealing lines, the steel coils are rolled continuously at room temperature. Its strength is very high, but toughness, weldability is slightly worse, bright surface, not easy to corrosion, in order to prevent rust, the factory surface is coated with a protective layer of oil (hot rolling did not). Because of the complexity of the process, the price is higher.
Q:What's the best material for color coated steel coil?
The base material of color coated coil is mainly galvanized steel or galvanized alloy steel plate.
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!
