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:On how to reinforce steel coils in a container
They can be strapped to the floor with wire ropes and locks
Q:Why is the steel tape tape head not fixed?
It makes sense to be irregular;You can see the standard ruler of steel roll head is a gap, when you take the time to object quantity, the head will indent the gap, so you measure is the size of the head from the head of steel;When you hook the object, the head will pull apart and you'll take the dimension from the end of the steel head.
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?
And may make the level stacked steel coil collapse, rolling, produce production safety accidents.
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: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 does "steel roll number" mean?
Steel coil number is the specification of steel coil.
Q:A roll of 1 meters wide color steel roll about how many tons?
Color steel roll is a composite material, both steel and organic materials, both of them a little. Both the mechanical strength of steel plate and easy molding performance, but also organic materials, good decoration, corrosion resistance. 1 meters wide should also have length, wall thickness conditions to know how many tons. The manufacturer is generally in accordance with customer requirements into a volume, the normal width of 1 meters per roll over 1 tons.
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.
