FAQ
1. Do you have QC team?
Yeah, sure, our QC team is very important, they will keep the quality control for our products.for quality inspection every day.
- Q:Is there any way to melt steel without the intense heat of a blast furnace?
- How To Melt Steel
- Q:What are the different types of steel coil recoiling methods?
- There are several different types of steel coil recoiling methods, including oscillating recoiling, flying shear recoiling, and rotary recoiling.
- Q:How are steel coils inspected for surface cleanliness during processing?
- Steel coils are inspected for surface cleanliness during processing through various methods such as visual inspection, magnetic particle inspection, and ultrasonic testing. These techniques help identify any contaminants, defects, or surface irregularities that may be present on the coils, ensuring their quality and suitability for further processing or use.
- Q:Iron too heavy for Ulysses but if there was any iron used id imagine it was steel. Can steel go deeper into sun than iron? Compare two bolts.. 1steel 1iron..is there a difference to what the steel can do?
- Dont understand are you going to put them in sun ? Sun made from gas wich is on fire. Its impossible to get to the sun and not to get burn. Steel is really more solid and strong than iron so its more hard to break it or to bend. But in camparing of fusion temperature - iron is a bit more better, though it would not make a big difference .From metals - tungsten has the highest fusion temperature - near to 3400 C . Iron is near to 1530 C, steel is near to 1300 -1500 C. So according to this tungsten can go most close to sun. Right near the sun temperature is millions of degrees so anything will fuse and burn there.
- Q:How are steel coils used in the production of storage tanks and silos?
- Steel coils are used in the production of storage tanks and silos as they provide the necessary structural strength and durability required for these storage structures. The coils are formed, cut, and welded into the desired shape to create the walls and roofs of the tanks and silos. This ensures that the storage vessels can withstand the weight of the stored materials and any external forces exerted on them.
- Q:How many millimeters is a number 3 steel crochet hook?
- In the rest of the world, a #3 hook is 6.5 mm. But the thing to do is use the hook size according to the yarn you are using. You would never follow the pattern exactly for hook size, you know that! You must do a gauge swatch to find out what YOUR tension is, and if that yarn will make the kind of fabric YOU want. You need to do a little research on this... as you know. Don't you remember your first lesson when you took your basic beginner class? Review your notes.
- Q:Steel is no doubt a better constructin material but it is only in practice in developed country.i would like that we should high lights the benifits and negatives of steel to make the steel more clear as a construction material.Hope some expert to address this topicMD
- Steel Structure considered as the most efficient and fast in completion of any project, specially the high rise buildings, also the logistics during construction is less complicated than the normal methods, Steel Structure has so many advantages vs the disadvantages, and highly recommended for commercial buildings
- Q:Why are steel saucepans and tea kettles covered with copper on the outside and the bottom? what r the goals of having high-quality pans that are thick and tea kettles that are thin walled?
- The issue is heat conduction. Copper trasferrs heat rapidly and therefore ensures uniform heat around the base or sides of teh pot. The thick walls can be two different purposes. Sometimes the steel is made in layers for the purpose of providing insulation. If a pot insulates heat then the heat will transfer in a steady manner and the need for constant fuel heat is reduced. Thus, if I want to simmer and can store some of the heat in the pot itself then I know it will transfer slowly because it has to go through the layers first. Secondly, the layers will transfer heat between them allowing for uniform heating and this avoids hot spots. Wash you pots with an acid. Lemon will clean copper very nicely. If you have to scrub then heat gently and use salt or baking soda as an abrasive. With a tea kettle you do not care about heat conduction past the point of the boil. when the boil arrives the job is done.
- Q:How are steel coils processed and treated?
- To ensure the quality and suitability of steel coils for different applications, they undergo a series of steps and treatments. Initially, the coil is uncoiled by removing its protective wrapping and unwinding it. Any defects like cracks or uneven surfaces are then inspected. Next, the coil is cleaned to eliminate dirt, oil, and rust using chemical agents and mechanical scrubbing. After cleaning, it is rinsed and dried to prevent corrosion caused by residual moisture. Once cleaned, the steel coil may be treated based on its intended use. One common treatment is pickling, where the coil is immersed in an acidic solution to remove impurities and scale. This improves the surface finish and prepares the steel for further processing. After pickling, the coil can undergo cold rolling, which reduces its thickness and improves dimensional accuracy. This is done by passing the steel through a series of rollers at room temperature, gradually decreasing thickness and increasing strength. It also improves the surface finish. In some cases, the coil may undergo additional heat treatments like annealing or tempering. Annealing involves heating the coil to a specific temperature and slowly cooling it to relieve internal stresses and improve mechanical properties. Tempering, on the other hand, involves reheating the coil to a lower temperature and rapidly cooling it to enhance strength and toughness. Once the desired processing and treatments are completed, the steel coil may be coated or painted for added protection against corrosion or to enhance its appearance. Coating processes can include hot-dip galvanizing, electroplating, or applying organic coatings like paint or powder coatings. Finally, the processed and treated steel coils are cut into specific sizes or shapes according to customer requirements. This can be done using cutting methods such as shearing, slitting, or sawing. Overall, the processing and treatment of steel coils involve cleaning, pickling, rolling, heat treatment, coating, and cutting processes. These steps are carefully carried out to ensure the quality, strength, and suitability of the steel for its intended applications.
- Q:What are the dimensions of steel coils used in the energy sector?
- The dimensions of steel coils used in the energy sector vary depending on the specific application and requirements. However, common dimensions range from 0.3 to 3 millimeters in thickness and 600 to 2000 millimeters in width. The inner diameter of the coil typically ranges from 508 to 610 millimeters, while the outer diameter can vary from 1000 to 2000 millimeters. It's important to note that these dimensions can be customized to suit different needs and specifications.
