Forging is a manufacturing process that uses compressive forces to form metal into the desired shapes and sizes. Industry professionals employ a variety of different forging techniques—depending on the material and the product being forged—each of which carries its own advantages and best uses.

Forging is the process of deforming metal into a predetermined shape using certain tools and equipment—deformation is accomplished using hot, cold, or even warm forging processes. Ultimately, the manufacturer will look at a number of criteria before choosing which type of forging is best for a particular application. Forging is used where the arrangement of the grain structure imparts directional properties to the part, aligning the grain so that it will resist the highest stress the part will encounter. Casting and machining, in comparison, usually have less control over the arrangement of grain structure.

Cold And Hot Forging: Fundamentals And Applications

Forging is one of the common manufacturing processes, that shapes a metal piece by applying compressive forces on it. Forging could be performed under different temperature conditions, like hot forging, warm forging and cold forging. The forging process uses hammers or presses to squeeze and deform the material into high strength parts. The forging manufacturing process is completely different from the casting one, where the molten material is poured into a mold see difference between forging and casting. This makes forging served in various industrial applications. The hot forging process involves the application of extreme heat, with the desired temperature depending on the type of metal. Hot forging is typically the best choice for steel forgings used in technical applications and for deforming metal that has a high formability ratio.

Hot and cold forging are two different metal forming processes. While they are performed at significantly different temperatures, they deliver similar results. Several factors are taken into account when deciding between hot and cold forging. When a piece of metal is hot forged, it is heated to extreme temperatures. The average temperatures necessary for hot forging are up to degrees Celsius for steel, to degrees Celsius for Al-Alloys , and to degrees Celsius for Cu-Alloys. This kind of extreme heat is necessary for avoiding strain hardening of the metal during deformation. Traditionally, manufacturers choose hot forging for the fabrication of parts that have a greater influence in the technical arena.

Cold and Hot Forging: An Overview

Forging is a manufacturing process involving the shaping of metal using localized compressive forces. The blows are delivered with a hammer often a power hammer or a die. Forging is often classified according to the temperature at which it is performed: cold forging a type of cold working , warm forging, or hot forging a type of hot working. For the latter two, the metal is heated , usually in a forge. Forged parts can range in weight from less than a kilogram to hundreds of metric tons.

Forgings | The Difference Between Hot and Cold Forging

Он признался во всем - в том, как понял, что Северная Дакота всего лишь призрак, в том, что нанял людей, чтобы те убили Энсея Танкадо и забрали у него кольцо, в том, что столкнул вниз Фила Чатрукьяна, потому что рассчитывал продать ключ от Цифровой крепости. Сьюзан дошла до последней строки. В ней говорилось о том, к чему она совершенно не была готова. Последние слова записки стали для нее сильнейшим ударом. И в первую очередь я сожалею о Дэвиде Беккере.

Сьюзан чуть не свалилась со стула. - Что. - Может случиться так, что компьютер, найдя нужный ключ, продолжает поиски, как бы не понимая, что нашел то, что искал.  - Стратмор смотрел на нее отсутствующим взглядом.

Знает ли она, что именно вы собираетесь сделать с Цифровой крепостью. - И что. Хейл понимал: то, что он сейчас скажет, либо принесет ему свободу, либо станет его смертным приговором.

Вспомнить арифметику.

По спине Сьюзан пробежал холодок. - Конечно, - чуть слышно сказала.  - Танкадо подумал, что раз мы приостановили действие его страхового полиса, то можем приостановить и его. Постепенно она начала понимать. Время сердечного приступа настолько устраивало АНБ, что Танкадо сразу понял, чьих это рук дело, и в последние мгновения своей жизни инстинктивно подумал о мести.

 El queria que lo guardara. Он хотел его оставить, но я сказала. Во мне течет цыганская кровь, мы, цыганки, не только рыжеволосые, но еще и очень суеверные. Кольцо, которое отдает умирающий, - дурная примета. - Вы знаете эту девушку? - Беккер приступил к допросу.
