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?
When placing materials to roll on both sides of the main pad wood pallets, prevent rolling back and forth. In addition the floor should be thickened, cannot have uneven or debris, because the line of steel coils when gravity concentrated in contact with the ground floor, there is a fracture easily, debris, easy to leave the indentation in the steel roll.
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 brand steel tapes are of good quality?
Personal feeling is also good for the Great Wall Seiko tape, upstairs several estimates are the production of steel tape manufacturers, of course, that their goods well. Our unit now buy all the Great Wall Seiko goods, said the tape is good, not because it is so durable
Q:How to solve steel plate storage
Avoid steel plates touching the ground, fixing steel coils, and using pads to reduce accidental or dangerous movement.
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:The difference between aluminized color steel roll and ordinary color steel roll
Ordinary color steel roll is a composite material, also known as color coated steel plate, is used in the continuous production line on the production line after surface degreasing, phosphating and other chemical coating treatment, painted with organic coatings, made by baking products. Both steel and organic materials are a little bit different. Both the mechanical strength of steel plate and easy molding performance, but also organic materials, good decoration, corrosion resistance.
Q:What is the accuracy of steel tape inspection?
The project is through the detection of steel tape, steel tape each batch have the error him different, so do projects each into a batch of steel tape has to go through the inspection department, let this batch of steel tape has reached the same error range. All the measuring tools in this project are unified into these steel tape measures, so that the measurement error is guaranteed.
Q:Why can hot rolled coils be placed outside?
Because hot-rolled steel coils are generally used as raw material for semi-finished products, they have to be further used for pickling and cold rolling to make more use. The rust and dust can be removed after pickling
Q:Where do I need hot galvanized steel coils and color coated rolls?
The use of galvanized steel for color coated steel substrates, except zinc protection, organic coating on the zinc layer up covering the isolation effect, can prevent rusting steel, galvanized steel service life is longer, the coating steel plate galvanized steel long service life is 50%. However, the service life of the color coated plate with the same amount of zinc coating, the same coating and the same coating thickness will vary greatly in different regions and different parts.
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.
