The principle is that the magnetic material is heated.
그러므로, 일반적인 주방용기는 녹발생 방지를 위하여 비자성체인 알루미늄이나 스테인레스 스틸(SUS304)을 사용하는데 반면 인덕션 렌지에 사용되는 주방용기는 최소한 인덕션 렌지의 그릴에 닿는 부분, 즉 밑바닥이 자성을 갖고 있어야 한다.Therefore, general kitchen containers use non-magnetic aluminum or stainless steel (SUS304) to prevent rust, whereas kitchen containers used for induction stoves should have at least the magnetic part that touches the grill of the induction stove, that is, the bottom is magnetic. .
다시 말해서 인덕션 렌지용 주방용기의 밑바닥에 사용되는 소재가 Fe성분을 함유하고 있어야만 한다.In other words, the material used for the bottom of the induction stove kitchen container should contain Fe.
인덕션 렌지에 사용되는 남비, 프라이팬, 주전자, 압력밥솥 등과 같은 주방용기를 간략하게 설명하면, 비자성체인 주방용기 몸체의 바닥면에 자성강판이 부착되어진다.Briefly describing kitchen containers, such as pots, pans, kettles, pressure cookers used in the induction stove, magnetic steel plate is attached to the bottom surface of the non-magnetic kitchen container body.
통상 주방용기의 몸체는 27종 스테인레스 스틸(SUS304)을 사용하고 있으며, 자성강판은 Fe성분을 갖는 24종 스테인레스 스틸(SUS430)이 사용되고 있다.Typically, the body of the kitchen vessel is used 27 kinds of stainless steel (SUS304), the magnetic steel sheet is used 24 kinds of stainless steel (SUS430) having a Fe component.
그러나, 상기의 스테인레스 스틸제 주방용기나 알루미늄과 강판재질의 주방용기 등 이종재질의 주방용기는 용접공법에 의하면 제조가 가능하나, 간편하고 대량생산이 가능한 다이캐스팅(die casting)공법으로는 불가능하므로 이를 개발하게 된 것이다.However, the kitchen vessels of different materials such as the stainless steel kitchen vessels or the kitchen vessels made of aluminum and steel sheet can be manufactured by the welding method, but the die casting method can be developed by a simple and mass-produced die casting method. It is done.
