Color coil binding - also known as spiral binding - is a great way to put together great-looking documents whether you're working with short or long books. There are a few ways you can do this type of binding: by hand, with an all-in-one binding machine, or with a coil inserter. If you're interested in using an inserter, there are a few features you should look for when choosing one for your bookbinding needs. Here they are....A foot pedal. It's always a good idea to select an inserter that can be operated by a foot pedal. (The pedal typically comes with the device.)

The reason for this is that when you use a machine with a foot pedal, your hands will remain free. This gives you more control so you can get the results you want quickly and easily.A good number of rollers. The number of rollers an inserter has will more or less dictate how easy it will be to operate. Just about all devices have one or two rollers, with the latter being the easiest to use. However, if you have the chance to try out a variety of machines before purchasing one, you should do so. You may find that the one-roller devices work better for you. (It's usually a matter of personal preference.)The ability to gap the rollers. You might be wondering what "gap" means when it comes to coil binding. All that's involved in gapping is adjusting the space between an inserter's rollers. If your inserter allows you to do so, you'll be able to use larger binding coils. Which, of course, means you can put together thicker documents. (A caveat: if you choose to use a coil that's larger than 30 millimeters, you'll need to insert it into your document by hand.) So if you think - or know - you'll need to bind thick books, you absolutely should choose a device with rollers that can be gapped.A spine former. Another feature to look for is a spine former. While this feature sounds really complicated, it's actually not.

It's just a curved area of the device that can help you shape the spine of your document to match the coil you've decided to use. Doing this makes it easier to insert the coil, especially if the book you're working with is pretty lengthy.A recognizable brand name. Finally, the machine you choose should have been manufactured by a company that's known for making high-quality devices. A few brand names the tend to signify quality are Rhin-O-Tuff, Akiles, and Marlon.Choosing a coil inserter isn't really that hard and choosing the right one will make it very easy for you to complete your bookbinding duties. Looking for the above items is a great way to Wholesale galvanized steel coil ensure you'll make the right choice and end up with a device that can help be more productive. Color coil binding looks great and is easy to do, so try it out for yourself today.

Electric Resistance Welding (ERW) and seamless steel pipeis the biggest difference lies in the ERW has a weld, which is the key to the quality of ERW steel pipe. Modern ERW steel pipe production process and equipment, as the international community, especially the United States and other years of unremitting efforts, making the ERW seamless steel pipe has been a more satisfactory solution.It was the ERW seamless steel pipe is divided into geometric seamless and physical seamless.

Geometric seamless ERW steel pipe is to remove the internal and external glitches. Due to the structure and tool of the inner burr removal system, the burr removal of large and medium-sized steel pipes has been well handled. The burr can be controlled in -0.2mm ~ +0.5 mm or so. Physical seamless means that there is a difference between the microstructure of the weld metal and the base metal, which leads to the decrease of the mechanical properties of the weld area, and needs to take measures to make it uniform and uniform.The high-frequency welding heat process of ERW steel tube caused the temperature gradient in the vicinity of the edge of the tube, and formed characteristic regions such as melting zone, semi-melting zone, superheating structure, normalizing zone, incomplete normalizing zone and tempering zone. In the superheat zone, the austenite grain grows abruptly under the condition that the welding temperature is above 1000 , and the hard and brittle coarse crystal phase is formed under the cooling condition. Besides, the existence of the temperature gradient will produce welding stress.

In this way, the formation of the mechanical properties of the weld zone lower than the base metal case, the physical seamless through the local conventional weld heat treatment process is the use of medium frequency induction heating device will weld area heated to AC3 (927 ), and then 60m Length, speed 20m / min in the air-cooled process, if necessary, then water cooling. The use of this method to eliminate stress, soften and refine the organization, improve the comprehensive heat-affected zone mechanical properties of the purpose. At present, the world's most advanced ERW unit has been hot rolled steel coils widely used this method to deal with the weld, has achieved good results. High-quality ERW steel pipe not only can not argue out the weld, and weld coefficient of 1, to achieve the weld area of the organization and the base material match.

Japan iron and steel federation said on May 28, 2015 fiscal year (as of the end of March 2016) Japan's crude steel output will slip slightly compared with the previous fiscal year.Japan is the world's second largest producer of crude steel.In the face of high hot rolled steel coil manufacturers steel inventories and the double pressure of export prices, Japan's largest steelmaker, Nippon steel live gold company will drive the crude steel production down in the second quarter of this year compared to the previous quarter by 9%, the second big steelmakers JFE steel company will cut production by 4% to 5%.Japanese steel union expects fiscal 2015 Japan's crude steel output for 107 million - 108 million tons.

The agency had expected for the 110 million tons, about the production for the last fiscal year. Japanese steel union pointed out that, at present, the Japanese steel inventory adjustment to a reasonable level also need a longer time. Japanese steel union, according to data released in April, Japan's crude steel output of 8.402 million tons, fell 9.5%, fell 6.1% year on year, fell for eight consecutive months.In April, Japan's steel output of 6.374 million tons of converter, fell 10.9%, fell 6.3% year on year;Electric furnace steel production is 2.029 million tons, fell 4.6%, fell 5.4% year on year;Pig iron production of 6.403 million tons, fell 10.4%, fell 3.1% year on year, the first year-on-year decline since three months;Hot rolled steel output of 7.449 million tons, fell 11.2%, fell 5.5% year on year, year-on-year decline in six months.

Among them, the ordinary hot-rolled seamless steel pipe material production is 5.908 million tons, fell 12.3%. Special hot rolled seamless steel pipematerial production is 1.541 million tons, fell 6.6%.Japan's steel production has been falling since late last year, due to the consumption tax hike down car and housing demand, construction labor shortages also inhibit the Japanese steel demand. Meti estimates that Japan's crude steel production in the second quarter of decline of 4.9% from the first quarter, dropped to the lowest level in six years.
