Q: I have good quality knives that I sharpen with various things, but mostly with a fine, diamond encrusted dry stone (eze lap) . When I run them over the steel, it doesn't seem to make any difference. I've heard that it aligns the edge, whatever that means. Using a steel, is it all just for show ?

Q: What are the different methods of tension leveling for steel coils?
There are several methods of tension leveling for steel coils, each with its own advantages and applications. 1. Roller leveling: This method involves passing the steel coil through a series of rollers under high tension. The rollers are strategically positioned to apply pressure on the coil, effectively stretching and elongating it. Roller leveling is commonly used for thinner gauge coils and is effective in removing coil set, crossbow, and edge wave defects. 2. Stretch leveling: In this method, the steel coil is subjected to a combination of tension and elongation. The coil is gripped by clamps at both ends and then stretched using hydraulic or mechanical devices. This process helps to remove residual stresses, flatten the coil, and improve shape control. Stretch leveling is particularly suitable for thicker gauge coils and can effectively eliminate wavy edges and center buckle. 3. Temper rolling: This method involves passing the steel coil through a series of temper rolls, which apply pressure on the surface of the coil. Temper rolling is primarily used to improve the surface finish of the steel and enhance its mechanical properties. It can also help to reduce coil set and improve flatness. 4. Skin pass rolling: In this method, the steel coil is passed through a series of rolls that apply a light pressure on the surface. Skin pass rolling is typically performed after the primary leveling process to further improve surface finish, enhance flatness, and reduce surface defects such as scratches or marks. 5. Stretcher leveling: This method involves clamping the steel coil at both ends and then applying tension to stretch it. The stretched coil is then held in this position for a period of time to allow for stress relief and shape correction. Stretcher leveling is commonly used for thicker gauge coils and can effectively remove coil set, crossbow, and center buckle. Each of these tension leveling methods offers unique advantages and is suitable for different types of steel coils and specific requirements. The choice of method depends on factors such as coil thickness, desired flatness, surface finish, and the specific defects that need to be corrected.
Q: What are the common defects in steel coils?
During the manufacturing or handling processes of steel coils, several defects commonly occur. These defects have the potential to impact the quality and performance of the steel, making it crucial to identify and resolve them to ensure the production of top-notch steel products. Some of the typical defects found in steel coils are as follows: 1. Edge waves or buckles: This defect arises when the edges of the steel coil become wavy or buckled. It can be caused by improper winding, uneven cooling, or excessive tension during the manufacturing process. Edge waves can pose challenges in further processing and compromise the appearance of the final product. 2. Coil breaks: Coil breaks refer to longitudinal breaks or cracks that emerge in the steel coil due to excessive strain or stress. Improper winding, uneven cooling, or excessive tension during the manufacturing process can trigger these breaks. Coil breaks can negatively impact product quality and are a major concern within the steel industry. 3. Surface defects: Scratches, pits, or stains on the surface of steel coils are considered surface defects. These can occur due to improper handling, surface contamination, or inadequate cleaning processes. Surface defects can affect the steel's appearance and may also lead to corrosion or other performance issues. 4. Slivers: Slivers are thin strips or flakes that can peel off from the edges of the steel coil. Poor edge trimming, improper handling, or defects in the rolling mill can cause these slivers. Slivers can impede further processing and may also compromise the surface quality of the final product. 5. Weld defects: Weld defects can occur in steel coils that are made by welding multiple strips together. These defects can involve incomplete fusion, porosity, or cracks in the weld area. Weld defects can weaken the steel and impact its mechanical properties, rendering it unsuitable for certain applications. 6. Shape defects: Camber, coil set, or crossbow are examples of shape defects found in steel coils. These defects can be attributed to uneven cooling, improper winding, or tension variations during the manufacturing process. Shape defects can make processing the steel challenging and may result in dimensional inaccuracies in the final product. Manufacturers and users of steel coils must be aware of these common defects and take appropriate measures to prevent or mitigate them. Implementing quality control measures, following proper handling procedures, and conducting regular inspections can aid in identifying and rectifying these defects, ensuring the production and utilization of high-quality steel products.
Q: How are steel coils processed for different finishes?
Various methods can be utilized to achieve different finishes on steel coils. One of the most commonly used is known as coil coating. This process involves several steps, including cleaning, priming, coating, and curing the steel coil to obtain the desired finish. To begin, any contaminants on the surface of the coil are removed, followed by the application of a primer to improve adhesion. Finally, a specific paint or coating material is applied to the coil. The coated coil is then subjected to high temperatures to ensure proper adhesion and durability. Another method for processing steel coils is galvanization. This technique involves coating the steel coil with a layer of zinc to protect it from corrosion. Galvanization can be achieved through hot-dip galvanization, where the coil is immersed in molten zinc, or electro-galvanization, where a thin layer of zinc is electroplated onto the coil. The resulting galvanized finish offers exceptional corrosion resistance and can be further processed for various aesthetic finishes. Furthermore, different surface treatments can be employed to achieve desired finishes on steel coils. These treatments may include pickling, which utilizes an acid solution to eliminate scale and impurities from the coil, or mechanical treatments like brushing or grinding to create a specific texture. Following these surface treatments, a protective coating or paint can be applied to enhance the appearance and durability of the coil. In conclusion, achieving various finishes on steel coils necessitates a combination of cleaning, coating, curing, and surface treatments. The selection of specific methods depends on the desired finish and the intended application of the steel coil.
Q: If I wear a pair of thick wool socks, is walking around in the snow with steel-toed boots going to be a problem? I'm wondering if the steel will make my toes too cold.
Yes, steel-toe boots are cold, thick wool socks or not. Suggest using Cofra orange colored pull-on knee boots. Non-steel toe cap resistant to 200 joule (one and a half tons of crush protection), penetration resistance, cold insulation to minus 20, ankle protection, heat resistant outer sole 300 degrees for one minute, energy absorption of seat region, slip resistance, the biggest traction cletes I've ever seen and they look like big boots seen the acid trip pretending to be film titled: Yellow Submarine.

Q: What is the purpose of coating steel coils?
The purpose of coating steel coils is to provide protection against corrosion, enhance durability, and improve the aesthetic appearance of the steel. Coatings create a barrier between the steel surface and the environment, preventing moisture, chemicals, and other corrosive elements from reaching the metal. Additionally, coatings can offer additional benefits such as heat resistance, UV protection, and improved paint adhesion, making the steel coils suitable for a wide range of applications in various industries.
Q: I've heard different things bout them, though I do not know this. Oh, and if you know where you can buy some raw or get custom made stuff out of black steel please let me know it would be greatly appreciated. Oh and my friend told me there is a black steel that can be sharpened and silver will be underneath, is this also true? Thank you very much for answering ^^
My son is a bit and spur maker,I asked him about that and he told me that it is a tag they put on bits so a novice person will pay more for a bit that is not any better. Steel is Steel You should have a lot of bite with that bit because it is a pretty fine diameter. The black patina will wear off with use. BTW he just sent two silver bits to a big show in Reno Nev. I have not seen them or pictures of them but he has a $2,000 price tag on each of them. They must be real elaborate probably very fancy spade bits with highly engraved multicolored different metal butterflies on the ports.
Q: Ive been playing with my ping i3 graphite irons for 6 years now and some days i can hit it and some days i cant. Then i tried out my friends irons the other day and he had steel and i was hitting the ball anywhere i wanted it to go..Is that a fluke or is steel irons just better than shaft? I was thinking about trading my graphites for steel, is that a good idea??
Graphite Or Steel Irons
Q: What is the use for spring steel that take advantage of its unique properties?
The primary use is for springs. It can be deflected to a large extent by applying a force it will return to its original shape when the force is removed. The force/displacement relationship tends to be a constant. A lesser use is to use spring steel wire as a vibrating string on a stringed instrument.
