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: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?
Steel is usually stable in performance. One thing is that the environment should be dry, not rain, because the damp environment is easy to rust. As long as it's in a dry room, it's basically no problem.
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: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:What is the maximum width of galvanized steel strip, please? The galvanized coat is 275, and how long is one coil?
As far as I know, the galvanized rolls of WISCO are wider in width than other domestic steel mills, and can produce 2080 wide steel coils.
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: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: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: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:How are steel tape measures installed?
The spring piece is fixed on the shaft, the other end is connected with the measuring tape core, fixed tape shell with a shaft, the spring plate and a circle around the axis of the ruler core, wrapped after the ruler core extends from the outer end of the incision length of the shell, gently pull, the spring is tightened, the pull out the part from the incision and then removed around the shaft, then gently pull out, and then put the ruler core tied to the shaft, removed from the incision so repeatedly, until the spring to put all the ruler core recovery. Then a cotter pin on the central shaft installed on the lid, will tighten the screws.
