Abstract

The invention discloses a composite bottom piece for a frying pan. The composite bottom piece comprises, by weight part, 0.01-0.05 part of La, 0.01-0.05 part of Pr, 60-65 parts of Fe, 30-42 parts of Ni, 8-12 parts of Cr, 0.3-0.6 part of Mn, 0.5-1 part of Si, 0.3-0.5 part of N, 0.5-1 part of Ti, 0.2-0.4 part of Al and 0.06-0.08 part of C. By means of the composite bottom piece, the excessively-hightemperature can be effectively controlled; and the composite bottom piece is not prone to rust and long in service life.

Description

technical field [0001] The invention relates to the technical field of hardware products, more specifically, it relates to a composite bottom sheet for frying pans and its preparation method and application. Background technique [0002] With the development of society and the advancement of science and technology, induction cookers have entered thousands of households due to their advantages of cleanliness, safety, and ease of use, and have become one of the indispensable household appliances in family life. The frying pan used on the induction cooker is made of a composite magnetizer at the bottom of the pot body (that is, a composite film), and the compound film is responsible for magnetic conduction, that is, a large amount of heat is generated by the compound film. [0003] As people put forward new requirements for the application of induction cooker, such as wishing to control the heating temperature of the frying pan well, so as to avoid overheating dishes from being...
