3. Production Flow about stainless steel sheet
Raw materials are sending to hot rolling units for rolling into different sizes
Hot rolled material is annealing in cold; rolled annealing furnace and pickling in acid.
All mill rolls are grinded on precision grinding machine with proper chamfering after first shiftoperation.
All sheets are pickled in different tanks and dried on brush roll machine before dispatched.
These sheets are again annealing and are sent to straighten machine for straightening.
Inspections are done at various stages. Keep proper control overall internal process via rolling,annealin and pickling by our experienced staff.
- Q:In the warehouse management system of steel coil
- Warehouse is an important component of enterprise material supply system. It is also the tache of enterprise material circulation and storage, and it also undertakes many functions of material management. Its main tasks are to keep the stock well, to be accurate, to be of good quality, to ensure safety, to prompt the people, to produce, to be considerate, to reduce costs, and to speed up capital turnover.
- 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:Why cold rolled stainless steel sheet is lower than cold rolled stainless steel coil?
- If it is calculated in accordance with the board, then his sales price should be 1*1*2*7.93*10=158.6 yuan / ZhangIf it is calculated according to the volume (assuming that the sales price is consistent), 0.9*1*2*7.93*10=142.7 yuan / ZhangSimilarly, a piece of stainless steel, if sold at the same price, leads to different prices. So in order to let both plate or rolling up to the same price, the price will be lower than the plate volume price, so the same with the price of the goods..The specific proportion of their conversion, can calculate the price of the goods in accordance with the principle of.
- 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 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: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: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: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.
- Steel rolls are also called steel belts. There is no difference between them. They are not flat steel
- Q:The strip tower height
- Causes: the strip has a larger snake shape; the take-up device holds the tension; the setting is unreasonable; the strip goes into the coiler; the centering is not good; the coil tension is not set properly.
- 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.
