Q&A on Induction Heating from Josam
Are you new to induction heating? Don't worry - Josam will answer all your thoughts and questions. Below is a list of the most common questions re- garding induction heating technology and the range of induction heaters from Josam.
What is induction heating?
Induction heating is the process of heating an electrically conducting object (usually a metal) by electromagnetic induction. Eddy currents (also called Foucault currents) are generated within the metal and resistance leads to Joule heating of the metal. An in- duction heater consists of an electromag- net, through which a high-frequency alter- nating current (AC) is passed.
What can I use an induction heater for?
When a damaged vehicle frame is straight- ened, with for example the frame straight- ening system Josam i-press, induction heating provides a great help. Certain ar- eas of the frame can be heated to make the

metal frame easier to work with. An induction heater also comes in handy when old rusted bolts and machine parts must be loosened. The more powerful the induction heater, the more advanced and heavy workshop tasks can be performed. Examples of applications for an induction heater are: sheet metal straightening, loos- ening of machine parts, loosening of rusted nuts, pins and bolts, loosen- ing of bushings and clamping rings, frame straightening etc.
What are the benefits of induction heating?
It's fast, easy and safe! Compared to heating with an open flame, an induc- tion heater can be used with less risk of damaging heat sensitive machine parts nearby. Handling gas in your workshop involves a lot of risks. You don't have to worry about that at all if you're using an induction heater in- stead. Josam's induction heaters are mounted on wheels and have gener- ous lengths of power and induction cables so they can easily be moved to where ever you need them in the workshop.
Isn't it better to use a gas torch?
With induction heating you have 100% control over what area you are heating and the heat does not spread
Josam回答有关 感应加热的提问
您对感应加热这个课题知 道得不多?无需担心— Josam将回答您有关这方 面的所有疑问。以下是有关感应加热 科技方面最常见的问题和Josam的感 应加热系列。
什么是感应加热?
感应加热是采用电磁感应为导电物体
加热(通常是金属)。涡流(佛科电
流)是应磁场变化而起于磁场内金属
之感应电流，电阻导致金属焦耳热。
感应加热器包含一个让高频率交流电
经过的电磁铁。
我能够采用感应加热器做什么?
当我们采用比如说Josam i-press 来 矫正和修复受损的车架时，感应加热 器就能提供相当大的帮助。车架的某 些部分能够被加热，以便金属的车架 易于修复。当我们要松开生锈的螺栓 和机器部件时，感应加热器也就派上 用场了。感应加热器的电力越大，就 能在修车厂里进行更先进和更重型的 工作。比如，感应加热器可以被使用 来矫正薄板，松开机器的部件和生锈 的螺栓和钉子、松开套管和固定环及 矫正车架等。
感应加热器有何好处?
它快，容易使用及安全。与明火相 比，使用感应加热器可降低对热敏感 机器部件的损坏。在修车厂里使用瓦 斯，危险性很高。如果使用感应加热 器，您就无需担心这一切。Josam的 感应加热器是安装在轮子上的，而且 拥有相当长的电力和感应电缆，以便 使用者能够轻易地在修车厂内将它们 移动到所需要的地方。
采用气炬不会比较好吗?
采用感应加热器，您能够百分之百控 制您要加热的范围，而且在加热时热 气不会像使用传统气炬般快速扩散。 感应加热器可提供您如明火般的功 能，但是却更为安全。如果您习惯在 修车厂中使用明火，您会发现感应加 热器拥有比气炬更多的优点。
