关于电磁炉

[lucky star]

我正考虑厨房买电磁炉还是普通电炉？用过的朋友介绍一下经验？还有电磁炉的辐射怎样？

辐射就不知道了，但是电磁炉对锅的要求比较高，得是magnetic的底儿

any cast iron, stainless steel, iron cookware will work on it... i have a single cooktop for 火锅, almost most of my 锅 can be used on it. no work on 铝,铜,陶瓷de锅.

谢谢楼上2位，电磁炉对锅的要求知道了。我是想买那种电磁炉stove, 不是电磁炉火锅用。

Be careful with the source of the info - It is from an org that promotes induction devices...

Do you believe the power lines or cell phone might cause health harzards to human body?

If you do, for peace of mind, think twice

good point. also see some websites talking about potential air pollution caused by gas range all kind of facts need to be considered and make your choice to your comfort level.

一说any就太绝对了，我家的stainless steel的锅，电磁炉就不能用。所以我说底儿得是magnetic的。

Steel is magnetic.

Steel is magnetic.

not all of them...

thanks, good good study, day day up!

Question

[SIZE=-1] Is stainless steel magnetic? Does it depend on the amount of chromium, or nickel alloy?

Asked by: James McGuigan

[/SIZE] Answer

[SIZE=-1] Stainless steels are a very broad group of metals. The name was adopted as a generic term for steel alloys with a minimum of 10.5% chromium. The chromium gives the steel its 'stainless' properties - essentially corrosion resistance. On the surface of the metal, a very thin chromium-rich oxide layer is formed which is inert - i.e. it prevents the steel from rusting. The advantage of stainless steels over plated steels is that, if scratched or damaged, the steel will 'self-repair' as a new oxide layer is formed. In plated steels, scratches in the plate will often lead to corrosion of the steel underneath.

In general, the higher the proportion of chromium, the stronger the corrosion resistance of the steel. In addition to chromium, other metals are added to give the steel particular properties such as strength and malleability. Specifically nickel is used to strengthen the oxide layer.

As for whether they are magnetic, the answer is that it depends. There are several families of stainless steels with different physical properties. A basic stainless steel has a 'ferritic' structure and is magnetic. These are formed from the addition of chromium and can be hardened through the addition of carbon (making them 'martensitic') and are often used in cutlery. However, the most common stainless steels are 'austenitic' - these have a higher chromium content and nickel is also added. It is the nickel which modifies the physical structure of the steel and makes it non-magnetic.

So the answer is yes, the magnetic properties of stainless steel are very dependent on the elements added into the alloy, and specifically the addition of nickel can change the structure from magnetic to non-magnetic.

The following company website has a useful high-level definition of the broad stainless steel categories. http://www.parkrow.org/stainless_steel.htm[/SIZE]

电磁炉与stove比有哪些好处呢?省电吗?

谢谢

学习了，电磁炉真的很方便。

这里用电的炉子，因为受热方式，总是糊锅，很不爽
