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.
Products Picture
- Q:What are the different types of packaging for steel coils?
- The different types of packaging for steel coils typically include wooden crates, steel frames, and plastic wrapping. These packaging materials are used to provide protection and secure the steel coils during transportation and storage.
- Q:I just started playing guitar last year. I never changed the chords. When my sister started taking guitar lessons her teacher said that she needed to change the chords. When i bought the guitar it came with steel strings but i bought nylon strings because they are easier on the fingers. The problem is i already tuned up the guitar but it sounds really bad like if it was not tuned. What can i do about this?
- Both are designed deferentially, they have their own sound and music distinction and so as their string you should use what is appropriate to them.
- Q:What are the common applications of steel coils?
- Steel coils have a wide range of applications, commonly used in industries such as automotive, construction, manufacturing, and appliances. They are utilized for making various products including automobiles, pipes, electrical appliances, roofing, and packaging materials.
- Q:How do steel coils perform in corrosive environments?
- Steel coils exhibit excellent performance in corrosive environments due to their inherent resistance to corrosion. This is primarily because steel, being composed of iron and various elements like carbon, produces a protective layer called a passive film. This passive film acts as a barrier between the steel surface and corrosive elements, effectively preventing direct contact and minimizing the risk of corrosion. Moreover, steel coils can be coated with different protective coatings to enhance their corrosion resistance. Coatings like zinc or epoxy provide an additional layer of protection, significantly prolonging the lifespan of steel coils in corrosive environments. However, it is important to acknowledge that the performance of steel coils in corrosive environments can still be influenced by factors such as the type of corrosive agent, duration of exposure, and presence of other contaminants. In highly aggressive environments, such as those with high humidity, exposure to saltwater, or acidic chemicals, the protective layers on steel coils might deteriorate over time, thereby increasing the potential for corrosion. To ensure optimal performance in corrosive environments, it is advisable to choose steel coils with corrosion-resistant properties, such as stainless steel or galvanized steel. Regular maintenance and inspections are also crucial to promptly detect any signs of corrosion and implement appropriate measures to prevent further damage. In conclusion, steel coils generally exhibit good resistance to corrosion in most environments, but the severity of the corrosive conditions can ultimately impact their performance.
- Q:I Don't have a Oxy act. torch but can Get a Propane one. The finished part(s) are .375 x .550 x .185
- An oxy would really be preferable, but a propane may do, I'm not sure you'll get an adequate temperature. They only way is to place the parts upon a clay brick or something simmilar, this will help the steel to hold it's heat, heat until cherry red. It must be vissibly red throughout the whole part at the same time and dumped immediately into cold water. If it's not completely cherry red, proper hardening will not occur and weak spots will be present. good luck
- Q:How are steel coils used in the manufacturing of railroads?
- Steel coils are used in the manufacturing of railroads as they are the primary material for constructing railway tracks. These coils are processed to form rails, which are then laid down to create the tracks on which trains run. The durable and strong nature of steel coils ensures the tracks can withstand the high loads and stresses imposed by trains, ensuring safe and efficient transportation.
- Q:i found a similar question asking what metals were in stainless steel but i don't know if they are the same.... they probably aren't.
- steel is iron with a little bit of carbon mixed in. how much carbon determines the hardness of the steel. stainless steel is the same mostly, it has nickle and chromium added in to make it corrosion resistant.
- Q:How are steel coils used in the manufacturing of construction cranes?
- Steel coils are used in the manufacturing of construction cranes to provide structural strength and durability. These coils are typically shaped and welded to form the main framework of the crane, which supports heavy loads and ensures stability during operation. Additionally, the steel coils are used to fabricate various components such as the boom, jib, and counterweights, which contribute to the crane's lifting capacity and overall functionality.
- Q:Can steel coils be used in the food processing industry?
- No, steel coils are not typically used in the food processing industry due to the risk of contamination and potential health hazards. Food-grade materials such as stainless steel are preferred for their hygienic properties and ability to withstand high sanitary standards.
- Q:I asked a question last week about stainless steel and got some great answers. I combed all over the internet to try to figure this one out but could not find anything. What resists bending better: chrome vanadium steel (i.e. a steel commonly used to make tools) or stainless steel 304. My guess would be the chrome vanadium alloy but thats just a guess. Which on resist's bending better and by how much (#'s please :-)). Also, if anyone knows if chrome vanadium steel is cheaper than stainless steel 304 that would be awesome? I can't find a price per pound on chrome vanadium steel anywhere! Please help. Thanks in advance-Josh
- Type 304 stainless steel can be tempered to give tensile strength up to about 125,000 psi. There are many chrome vanadium alloys, and tempers, but they are generally very hard steels used for machine tools which are used to cut other steels. They generally are much stronger, and can be hardened up to tensile strengths of 250,000 psi and beyond. (Bending strength is proportional to tensile strength, but Cr-V steels are not usually used for beams or other structure members.) Cr-V steels are specialty alloys and will probably be a good bit more expensive per pound than common stainless alloys. For any steel, price depends on the form you are buying, i.e. plate, bar, or other shape, as well as the alloy and temper specified, and the quantity. You need to get prices from a supplier. You can find some online catalogs, but you usually have to call the vendor for price info.
