Q:How are steel coils recycled?

Steel coils can be recycled through a process that involves melting them down in a furnace, removing impurities, and then shaping the molten steel into new coils or other steel products. This recycling method helps conserve resources, reduce waste, and significantly cut down on energy consumption compared to producing steel from raw materials.

Q:What is the size range of steel coils?

The size range of steel coils can vary depending on the specific application and industry. Generally, steel coils come in a wide range of sizes to accommodate different needs. The width of steel coils can range from as narrow as a few inches to as wide as several feet. Similarly, the thickness of steel coils can vary from very thin gauges, such as 0.005 inches, to thicker gauges exceeding 0.5 inches. The length of steel coils is typically determined by the manufacturing process, but it can be customized to meet specific requirements. Overall, the size range of steel coils is quite extensive, allowing for flexibility and adaptability in various industries, such as automotive, construction, and manufacturing.

Q:How are steel coils protected from humidity?

Steel coils are typically protected from humidity through a process called galvanization, where a layer of zinc or another protective coating is applied to the surface of the steel. This coating acts as a barrier, preventing moisture from coming into direct contact with the steel and minimizing the risk of corrosion. Additionally, steel coils are often stored in dry, enclosed spaces or wrapped with moisture-resistant materials such as plastic or wax paper to further protect them from humidity.

Q:What are the common uses of cold rolled steel coils?

Cold rolled steel coils have a wide range of common uses such as in automotive manufacturing, construction, appliances, furniture, and general engineering applications.

Q:I was cutting a sheet of steel with an angle grinder when suddenly the rate at which the blade was cutting slowed way down. I tried a few different things, and turned off the tool and looked at the blade. It didn't look damaged, but it definitely was not cutting as quickly. I thought either I had hit a harder section of steel (is that possible? It looked pretty uniform) or the blade had lost it's abrasive quality or something. Also, before this happened I had accidentally cut into the wooden sawhorse that was holding up the steel sheet, but I've done that before with no problem. After a short while the problem fixed itself and the rate of cutting went back to a fast normal. Anyone know why this happened?

Your blade was overheated. Change it into diamond blade shall do.

Q:How are steel coils inspected for thickness?

To ensure their quality and compliance with industry standards, steel coils undergo inspections for thickness using a range of methods. One widely used approach is the utilization of a non-contact laser measurement system. This technique involves directing a laser beam towards the surface of the steel coil and measuring the time it takes for the beam to reflect back. By accurately calculating this time, the thickness of the steel coil can be determined. Another method involves the use of ultrasonic technology. Ultrasonic sensors emit high-frequency sound waves that penetrate the coil. These sound waves bounce back differently depending on the thickness of the steel, enabling the sensors to measure the thickness accurately. In addition, some manufacturers may choose to employ the eddy current testing method. This method involves passing an alternating current through a coil, thereby generating a magnetic field. The thickness of the steel coil affects the impedance of the coil, which can be measured. By analyzing the changes in impedance, the thickness of the steel coil can be evaluated. Furthermore, some companies utilize a mechanical method known as the caliper method. This technique involves physically measuring the thickness of the steel coil by applying pressure to the coil and reading the measurement on a caliper gauge. Regardless of the method utilized, it is essential to inspect steel coils for thickness to ensure they conform to the required specifications and meet the desired performance criteria for various applications.

Q:Hi there! I just purchased two cookie sheets labeled as non-stick 100% carbon steel. I've never heard of carbon steel before, and I'm trying to be careful about not using certain products that are harmful to health such as aluminum and Teflon. Is this a safe metal choice for baking?

Yes. Carbon steel is one of the most common metals used by human beings. When the Bronze Age ended and the Iron Age started, most of the iron humans could make was carbon steel. A Cast Iron frying pan is carbon steel (well... technically, there are differences between cast irons and steels but... anyway). Our cast iron frying pans (almost the only fry pans we have used for 30+ years) are mostly non-stick because we keep them well seasoned. Humans need iron in our diet anyway. You might want to check to verify what (if anything) it is coated with to make it Non-stick because, in general, steel cookware is stick. If it is coated with ceramic (enameled), then there won't be any rust because the iron is coated and protected from water. The non-stick ceramic coatings are very good. Ceramics are chemically inert to almost everything on earth (all but some of the most exotic chemicals you will ever find in a Chem Lab). As a side note... a large number of studies of industrial exposure to aluminum and aluminum compounds (people who work in Al production plants and are exposed to large quantities for years and years and years) has shown that there is NO correlation with Alzheimers or any other diseases. The major health risk for these populations was lung problems due to inhalation of fine dust (which, turned out, was not even as bad as breathing, for example, dust containing cotton fibers in garment workers).

Q:what do you think about producebility of low density steel? for example: can density of 1020 steel (or ony others) be decreased without any loss of other properties.

1. A method has been developed for magnetic phase analysis of Fermanal type alloys as-quenched and after aging. 2. The upper limit of alloying to ensure the optimal mechanical properties was determined more precisely for steel 9G28Yu9MVB. For rods aged at 550°C for 16 h the aluminum content should not exceed 9.2% and the carbon content 0.92%. 3. To ensure the optimal mechanical properties of the deformed metal it is necessary to obtain a fine-grained single-phase austenitic structure after quenching. The amount of hardening phase after quenching should not exceed 15–20% (saturation magnetization around 1600 G).

Q:What's the best way to clean granite countertops and stainless steel appliances? My countertops especially always look dull and streaky. Thanks!!!!!!!

The best home remedy for that is shaving cream. Use men's shaving cream, not the gel, and not the ones with aloe, but regular shaving cream. It'll get the crud off and it'll shine it up for you. Just make sure you wipe it down really well, so there aren't any streaks.

Q:How hot does steel have to get before it will melt?

Type your query into Yahoo! Search or other search engines to get the answer: It depends, since steel usually has different metals added for various properties (strength, corrosive resistance, etc.)
