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 is the material of steel coil 08F and what brand can be used instead?
20 steel used for various mechanical parts is not subjected to great stress and toughness, such as rod, sleeve, screw, lifting hook; also can be used for manufacturing in 60 pressure and 450 DEG C using non corrosive medium pipes, pipe; can also be used for carbon and cyanide carburized core strength is not the chain, such as bushings, roller, shaft and gear, sprocket and other important.
Q:The difference between aluminized color steel roll and ordinary color steel roll
Aluminized color coated sheet is a new type of material produced in China in recent years due to its high end applications. It is often used as an indication of CCLI. It is made of galvanized steel sheet (55% aluminum, 43% zinc and 1.6% silicon), which is more galvanized and more corrosion resistant. It is processed by surface degreasing, phosphating and complexing treatment, and is coated with organic coating.
Q:Several reading methods of steel tape measure
Precise steel tape factory and after a period of time must go through the verification and indicate the verification of temperature, tension and feet. Feet marked on the length of its nominal length, and the difference between the actual length is called length correction delta l ruler by different tension will make feet long. To avoid this change requires the use of steel tape according to the scale mark force of steel tape. At different temperature the foot will change with the temperature so it is necessary to use t as variable function to represent the feet long, this is the ruler length equation, its general form:
Q:How can the outer diameter and weight of steel coil be converted?
To obtain the outer diameter of the steel coil is calculated according to the density of 7850, according to the density, in general, hot-rolled is 0. 96~0, 98, cold rolled, according to 0. 98~0. Ninety-nine
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 does "steel roll number" mean?
Steel coil number is the specification of steel coil.
Q:Is a steel plate the same as a steel coil?
You must have an open book and a flat plate, and it is a little bit harder to cut the parts than the plate.
Q:What's the length of a coil of cold rolled steel? Is there a standard?
In 2.0*1000*C calculations, it is assumed that the formula for the length of 5T in this volume is 5000/ (2.0*1000*1000*7.93) = the total number of meters. First, the weight of one meter is calculated by dividing the total weight by the single weight, that is, the theoretical length of the volume
