Mechanics Rolling
Steel rolling mill machinery an important equipment in steel industry
In early times when there were no computers in this world and all the works were performed with physical efforts of men has now turned this technology so advanced that rarely any kind of work is optimized without machines and computers. Different types of machines are used for different kinds of work. Business over this world is divided into so many sections serving for different purposes. So today we'll discuss about the steel rolling mill machinery of India. With the advancement in technology people are inventing new things that are making their task easier and easier. Machines are one of those things. It has been categorized on the basis of their sizes, work type and costs. They are used for making steel, metal sheets etc.
Do you know what is metal and how it is made? Metal is an electropositive element which has shiny surface. It has good qualities and more efficiency. It is a good conductor of electricity and can be melted or fused in any shape by using high processed heating methods. We can make out of metal sheets by passing out them through the rollers en the machines are categorized under two categories. Hot rolling mill machinery & cold rolling mill machinery process carried out through steel rolling mill machinery. You may or may mot know that each and every metal has its own recrystallization temperature.
If the temperature of the metal is above its recrystalization temperature then it is termed under hot rolling mill machinery process and if the temperature of the metal is below the recrystalization temperature of the metal then the process is called as cold steel rolling mill machinery. With the help of these processes we are able to make sheets, plates and foils out of these. Sheets from the metal are used for construction, transport and aerospace. These sheets are used as well for airliner components. It is genuinely known that the plate form is more efficiently used than the sheet form as it is thinner than it but still both are used for same applications. Plate form of steels is commonly used for auto motive industry and foil form is thin so more flexible and used for packaging. It is also used for foil stamping. Besides this it has a wide use over the electronic sectors of industry for shielding. Moreover machinery of India has proved its worth over mechanical industry also. The unit that uses the steel rolling mill machinery is known as steel rolling mill plants. Some of the items like I-beams, hot strips, steel rods, plates and h-beams are generally used in steel rolling mill plants.
If you an owner of steel rolling mill plant and are in need of this steel rolling mill machinery then buy it from a well named company or you can simply refer to the site named machinesindia.com this site will enable you to reach the dealer who deals in this machine. This site also offers various product categories such as hand tools, pharmaceuticals machinery, machine tools, roll forming machinery, plant and machinery, oil mill machinery and lots more.

Please expain the phenomenon of rolling with slipping and rolling wihout slipping (rotational mechanics)?
I've read up quite a lot on this issue in books like Resnick Halliday and H.C Verma,and even certain websites,but there are certain areas that I just don't get--Like,how friction assists to prevent slipping,whether the friction in this case is static friction or rolling friction,when there is slipping what exactly is happening to the wheel,whether we can determine any details of the motion when there is slipping,etc.
Please don't suggest any websites or pickout sections from them, I'm tired of that!!
I'll be grateful for any help I get.
When rolling happens without slipping, the point of contact has zero linear velocity relative to the ground. When rolling with slipping happens, the point of contact with the ground has a non-zero linear velocity relative to the ground.
At the point of contact with the ground, the case of rolling without slipping is like pushing on a block where the block is not slipping because friction is able to overcome the applied force: so static friction hold the point of contact in place.
If the rolling is with slipping, and there is a point of contact with the ground, then the situation at the point of contact with the ground is analogous to the case of pushing on a block where the block is sliding despite the presence of friction: so dynamic friction is providing the retarding force. (The force of friction always tries to return the system to the rolling without slipping condition.)
You can tell when slipping is happening because the linear velocity of the body must always equal the rate of rotation of the body multiplied by the radius from the center of rotation to the point of contact. In this particular situation, the magnitude of the linear velocity at the edge of the rotating body is guaranteed to equal the magnitude of the linear velocity of the center of rotation. If this not the case, then there must be slipping at the point of contact: because either the center of rotation/mass of the body must be moving faster than the spinning motion of the rotation can move it (like when you slam on the brakes and the car starts to skid), or because the rotation is more rapid than the forward velocity of the body itself (like applying too much gas and spinning-out a car tire.)
