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?
General handling steel rolls are used for driving. Forklift trucks are OK, but a larger fork truck, usually cold rolled, weighs less than 15T. The hot rolled coil is below 30T.
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?
Hello! The reason is: 1. cold rolled flat plate is Kaiping;2. cold-rolled plates are negative tolerances.
Q:What is the maximum width of galvanized steel strip, please? The galvanized coat is 275, and how long is one coil?
The length of the roll is related to its width and thickness, but not to the extent of the zinc layer.
Q:On how to reinforce steel coils in a container
In the bottom and sides with a thick strip stuck, but also to ensure that the wood will not loosen down...... Rough steel rolls, I saw people loading and unloading on the docks, poked them directly with a small forklift truck, and then reinforced with wooden planks
Q:Why can hot rolled coils be placed outside?
Because the stress of participation should be eliminated
Q:Where do I need hot galvanized steel coils and color coated rolls?
Hot galvanized steel coils and color coated rolls have light, beautiful and good corrosion resistance, and can be directly machinedThe construction industry, shipbuilding, vehicle manufacturing, furniture and electrical industries provide a new type of raw materialThe utility model has the advantages of steel replacing wood, efficient construction, energy saving, pollution prevention and the like.
Q:The strip tower height
Defects: cold-rolled steel sheet (coil)
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.
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.
