Rare earth alloy iron pan and production method thereof

Abstract

A rare earth alloy iron pan production method includes: (1) smelting cast iron by an intermediate frequency furnace, and heating the iron molten iron till the temperature is higher than 1400 DEG C; (2) smashing rare earth ferrosilicon alloy till the size ranges from 2mm to 6mm, and preheating till the temperature reaches 60 DEG C; (3) placing the rare earth ferrosilicon alloy block with a quantity of weight ratio ranging from 0.3% to 1.8% in a ladle and then pouring the molten iron, and mixing and drossing; (4) casting after the molten iron is cleared, preheating a casting mold and injecting the molten iron to the mold, and pressing an upper pan mold down to form an iron pan; (5) taking out the iron pan after the iron pan is chilled in the mold, and clearing in a mechanical fine grinding and buffing manner; (6) feeding the iron pan into an electric furnace, heating till temperature ranges from 270 DEG C to 330 DEG C, painting edible vegetable oil on the pan body to form an oil film, and allowing oil molecules to penetrate in the pan body; and (7) taking out the iron pan and detecting. The rare earth alloy iron pan production method has good social benefit and economic benefit, and is adaptable to the field of iron pans.

Description

technical field [0001] The invention relates to kitchen utensils, and furthermore, to a rare-earth alloy iron pan and a production method thereof. Background technique [0002] Iron pots are essential cooking utensils in our country's family kitchens. Chinese iron pots have a long history. Using iron pots is good for your health. The World Health Organization recommends using Chinese iron pots. But the iron pan of the prior art has problems such as easy rust, short service life, and unattractive appearance. For solving these problems, people have proposed some new techniques and methods, such as application number 96105232.5 "luxury nutritional iron pan and its manufacture" technology", application number 91103394.7 "nodular cast iron pressure cooker and its manufacturing method", application number 92106603.1 "process method for antirust treatment of cast iron pan", application number 8610889.8 "a nutritional iron pot", etc., they all have their advantages, but still has ...
