Embodiment Construction

[0019]The present invention provides a surface treatment process for cast iron products. In order to make the objectives, technical solutions and effects of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0020]Seefigure 1, The present invention provides a surface treatment process for cast iron products, including the following steps:

[0021]A. Clean the surface of cast iron products; cast iron products are processed from casting or forging blanks, and the blanks are cast with sand during the casting or forging process, so there are often sticky sand residues on the blanks that need to be cleaned and cleaned up the cast iron products The sticky sand on the surface can make subsequent operations go smoothly.

[0022]B. Heat the cast...

Abstract

The invention discloses a surface treatment process of a cast iron product, which comprises spraying a layer of transparent antirust agent on the surface of the cast iron product after performing sand cleaning treatment on the surface, and firing at 165-180°C for 10-25 minutes , maintain the original metallic luster of cast iron, and play a role in preventing cast iron from rusting, the sprayed antirust agent is non-toxic and harmless, meets the requirements of food hygiene standards, and the process is simple to operate, and the obtained products can be used at high temperatures No cracking, no smell.

Description

Technical field[0001]The invention relates to the technical field of surface treatment of metals, in particular to a surface treatment process of cast iron products.Background technique[0002]Iron is the basic element that constitutes cells. 72% of the body's iron is contained in hemoglobin. Iron deficiency can cause anemia. There are limited iron intake channels in life, and the body can only absorb active iron. According to statistics, about 30% of children in the country suffer from anemia. Iron deficiency in women is particularly serious. Middle-aged and elderly people also suffer from anemia to varying degrees.[0003]Cast iron is mainly composed of iron, carbon and silicon. The active iron atoms contained in it are easily absorbed by the human body. The use of cast iron pots can improve anemia. Because of the less impurities, the heat transfer of cast iron pots is relatively uniform. When the temperature of the fire exceeds 200 ℃, the cast iron pot will By dissipating a certain a...
