Problems solved by technology

[0004] At present, stainless steel, aluminum, iron and other conventional metal materials are often used in the kitchen utensils industry and small household appliances industry, especially stainless steel is the most widely used. The main disadvantages of these kitchen utensils are: ① conventional metal materials such as stainless steel, aluminum, iron, etc. It has the characteristics that the temperature in the pot is always rising during the heating process; ②The temperature rises fast and it is easy to stick to the pot
The non-stick coating mainly contains fluorine-containing resins such as polytetrafluoroethylene, which has certain requirements on the operating temperature of the pot. The suitable operating temperature of the non-stick coating is below 260°C. When the temperature exceeds 260°C, the coating gradually becomes unstable. State transition, when the temperature exceeds 350 ° C, it will decompose, and it will easily release hydrogen fluoride gas. After this gas is dissolved in water, it is not only highly corrosive, but also relatively toxic. Therefore, the current non-stick pans do not have Anti-dry function, limited in use

Abstract

The invention provides a novel constant temperature material and a preparation method and application thereof. The novel constant temperature material comprises, by mass percent, 0.4%-1.4% of Si, 0.35%-0.855% of Mn, 8%-30% of Ni, 0.015%-0.3% of Nb, 0.3%-2% of W, 0.005%-0.12% of Sn, 0.001%-0.003% of rare earth elements and not smaller than 55% of Fe, where the rare earth elements comprise at leastone kind in La, Yb, Er, Ho, Nd, Lu and Ce. The Curie temperature of the novel constant temperature material ranges from 150 DEG C to 225 DEG C, the Curie temperature of the material can be effectivelyadjusted by adjusting the raw material kinds and component contents of the novel constant temperature material, and the novel constant temperature material can flexibly adapt to different heating requirements.

Description

technical field [0001] The invention belongs to the technical field of temperature control materials, and in particular relates to a novel constant temperature material and its preparation method and application. Background technique [0002] Curie point (Curie point) is also known as Curie temperature (Curie temperature, Tc) or magnetic transition point. It refers to the temperature at which the spontaneous magnetization in the magnetic material drops to zero, and it is the critical point at which ferromagnetic or ferrimagnetic substances transform into paramagnetic substances. Below the Curie point temperature the substance becomes ferromagnetic, at which point the magnetic field associated with the material is difficult to change. When the temperature is higher than the Curie point, the substance becomes a paramagnet, and the magnetic field of the magnet changes easily with the surrounding magnetic field. At this time, the magnetic sensitivity is about 10 to the negativ...
