- Q: Hi,Well, I live near almost across the street from a forest, and my neighborhood is full of raccoons!!! Recently, I just purchased a bunny and have kept it at my cousin's house for the time being. He has a steel cage, and is about 6 months old. I am considering bringing him home and leaving him in the back yard with his steel cage. I am just afraid that raccoons can bite through the steel and get to him. So the question is... Is is possible for raccoons to bite through steel? Btw,Please don't answer hate comments about me being a bad rabbit owner. I simply want to know if raccoons can bite through steel. If it doesn't work out, the rabbit will stay at my cousins house until further notice. But please, I did not waste 5 points for unneeded answers. Thanksss!
- Well the raccoons can't bite through steel unless it is very thin steel, like aluminum foil thickness. But they have long arms and can reach into the cage so that would be my worry. They are also very clever so I don't know if it is safe for the bunny. That would depend upon the size of the cage and how hungry the raccoons are. The raccoons might be tempted to try to steal the bunny's food so that is a concern. Check with a pet shop owner or forester or someone like that who has knowledge about raccoons in the area.
- Q: What are the different methods of tempering steel coils?
- There exist numerous techniques for tempering steel coils, each possessing unique advantages and disadvantages. Some of the most prevalent techniques include: 1. Air cooling: This method, the simplest and most commonly employed, involves heating the coils to a specific temperature and allowing them to cool naturally in the surrounding air. Although relatively speedy and cost-effective, this technique can result in uneven cooling and may lack precise control over the final properties of the steel. 2. Water quenching: In this approach, the steel coils are heated and then rapidly cooled by immersing them in a water bath. Water quenching provides a swifter and more controlled cooling rate than air cooling, resulting in increased hardness and strength. However, it may also cause heightened distortion and the development of internal stresses in the steel. 3. Oil quenching: Similar to water quenching, this method entails immersing the steel coils in an oil bath to rapidly cool them. Oil quenching offers a slower and more uniform cooling rate in comparison to water quenching, leading to reduced distortion and internal stresses. Nevertheless, it yields slightly lower hardness and strength than water quenching. 4. Salt bath quenching: This technique necessitates immersing the steel coils in a heated bath of molten salt for rapid cooling. Salt bath quenching ensures an even and controlled cooling rate, resulting in improved hardness and strength compared to air or water quenching. However, it requires specialized equipment and may not be suitable for all steel types. 5. Induction hardening: In this method, the steel coils undergo induction heating before being rapidly cooled using air, water, or oil quenching. Induction hardening permits precise control over the heating and cooling process, thereby achieving specific hardness and strength properties in desired areas of the steel. Nonetheless, it demands specialized equipment and is generally employed for specific applications or sections of the steel coils. Ultimately, the choice of tempering method relies on various factors, including the desired properties of the steel coils, the type of steel employed, and the specific requirements of the end application.
- Q: What are the common methods of testing the durability of steel coils?
- Common methods of testing the durability of steel coils include tension tests, impact tests, bending tests, hardness tests, and corrosion tests.
- Q: How are steel coils inspected for thickness and width accuracy?
- Steel coils are inspected for thickness and width accuracy using various methods. One common method is using non-contact laser or ultrasonic sensors that scan the surface of the coil to measure its thickness and width. These sensors provide accurate measurements without physically touching the coil. Additionally, manual measurements can be taken using calipers or micrometers to verify the accuracy of the coil's dimensions. Overall, a combination of non-contact sensors and manual measurements ensure that steel coils meet the required thickness and width specifications.
- Q: I saw a 27 sedan and a 27 Pick-up one had wood wheels the other steel, respectively. Witch one was original or were they both original
- Steel wheels were not available on the pickups until 1929. The cars had the options of steel disc or wood spoke wheels in the mid '20's. I'm pretty sure that '27 was the last year the wood wheels were available on passenger cars.
- Q: How are steel coils used in the production of metal ductwork?
- Steel coils are an essential component in the production of metal ductwork. These coils, typically made from high-quality steel, serve as the primary raw material for manufacturing ductwork.

These lengths are then shaped into the desired form using specialized machinery, such as roll formers or bending machines. The steel coils provide the necessary strength and durability to the ductwork, ensuring that it can withstand the pressure and environmental conditions it may encounter in its operational life. The coil's composition also allows for easy fabrication and customization, enabling manufacturers to create ductwork of various shapes and sizes to meet specific project requirements. Furthermore, the inherent properties of steel, such as its resistance to corrosion and fire, make it an ideal material for ductwork. Steel coils can be coated with protective layers, such as galvanized or stainless steel finishes, to enhance their longevity and performance. This added protection ensures that the ductwork remains intact and functional even in harsh environments or in the presence of corrosive substances. In summary, steel coils play a crucial role in the production of metal ductwork by providing the necessary raw material for fabrication. Their strength, durability, and customization capabilities make steel coils an indispensable component in the manufacturing process, resulting in reliable and long-lasting ductwork systems.

- Q: We are going to build a house with a steel frame.Someone told me today that these houses have problems with humidity.Is that true?Please tell me all you know..
- The humidity is not at all related to the framework of any house. Galvanized steel has become popular especially in commercial applications because lumber costs are increasing exponentially. Consider that any home built should be adequately ventilated, insulated, and certainly constructed. Consider where the house is,,,IE: Near water; in a tropical setting; prone to being in an area that floods; or gets a lot of rain. The exterior and interior of a steel framed house is the same as a wood frame. I'd go with block personally and steel roof rafters and joists. Once the house is built, adequate ventilating, heating, and/or air conditioning should be accomplished to keep the humidity levels tolerable, and not effect mold, mildew, excesssive heat, etc. Rev. Steven
- Q: How are steel coils cleaned before use?
- Steel coils are typically cleaned before use through a process called pickling, which involves immersing the coils in an acid solution to remove any scale, rust, or other impurities.
- Q: How are steel coils used in the production of steel chains?
- Steel coils are used in the production of steel chains by being unwound and fed into a machine that shapes and forms the individual links of the chain. The steel coils provide the raw material needed to create the strong and durable chains, ensuring they have the necessary strength and integrity for various applications.
