Cast iron enamel burner and preparation process thereof

Abstract

The invention relates to a cast iron enamel burner and a preparation process thereof. According to the high-temperature resistant cast iron burner of an enameled household stove and the preparation process thereof provided by the invention, enamel coating layers are sprayed in the cavities and on the outer surfaces of parts of the burner such as a fire cover, a burning tray, an ejector and the like according to the use requirements and the type of the burner respectively, and the coating layers have oxidation resistance and enhance the acid and alkali resistance, ageing resistance and rust resistance of the outer surfaces of the parts. When the enamel burner is used in a working environment of far higher than 600 DEG C, even burnt in open fire, the enamel burner does not become yellow or explode enamel. The enamel burner has the characteristics of resisting acid and alkali, thermal shock, high temperature and impact, containing no harmful elements to the human body and the like.

Description

technical field [0001] The invention relates to a cast iron enamel burner. In addition, the invention also relates to the preparation process of the cast iron enamel burner. Background technique [0002] The household gas ranges sold in the market are of a great variety in styles or shapes, and the structures of the burners of the household gas ranges are also varied. There are integral ones and split ones. Integral burner ( Figure 1 ) is generally composed of a burner (2) and internal and external fire dividers (1) (fire cover with fire holes); the split burner ( Figure II ) then consists of a fire distributor (1), a burning disc (2), a base (3) and an injector (4). The shape and material of the burner parts are determined by each manufacturer according to its style and manufacturing process. There are copper-aluminum combinations and iron-aluminum combinations. At present, the understanding is relatively consistent. The fire distributor is made of brass (HPb59-1), wh...

The production and preparation process is cumbersome and complicated

In addition, when this type of silicon-manganese steel enamel is used in the burner field of gas stoves, since the burner has been working in a high-temperature environment above 600 degrees for a long time, the high carbon content of silicon-manganese steel is likely to cause the enamel to burst, fall off, and yellow.
