Abstract

The invention discloses a cast iron stone electric cooker inner pot and a production method thereof. The cast iron stone electric cooker inner pot comprises a pot ear, a pot body, an inner chamber, a pot bottom, a stone powder layer, a lining layer, a body and an enameling layer. The cast iron stone electric cooker inner pot is characterized in that the outer layer of the body is the enameling layer, the inner layer of the body is the lining layer, the stone powder layer is arranged outside the lining layer, and the stone powder layer is formed by crushed powder of stones such as quartz, silicon chloride rocks and granite and is sintered and bonded on an iron pot. The production method comprises the steps of smelting molten iron in a medium-frequency furnace, molding in a sand mold, cleaning sand by using a shot blasting machine, performing machining, performing annealing treatment, spray-coating daily-use enameling materials on the outer layer of the pot, spray-coating metal powder layer and stone powder layer bonding materials on the inner layer of the pot, drying the materials, crushing the material by using a ball mill, adding bonding agent, performing agitation, performing spray-coating and drying to obtain the product. The cast iron stone electric cooker inner pot and the production method thereof have the advantages that the structure is simple, the process is advanced, the pot is clean and hygienic, is easy to clean and is attractive, the content of trace elements is high, the nutrition of food is retained, and the pot is pollution-free and belongs to a purely natural pollution-free pot.

Description

technical field

[0001] The invention relates to an electric rice cooker liner, in particular to a pig iron stone electric rice cooker liner and a production method thereof. Background technique

[0002] The electric rice cooker cooks quickly, automatically heats and keeps warm, convenient, trouble-free, worry-free, and time-saving, and solves the complicated life of thousands of households. Aluminum metal or heavy metals are easy to infiltrate into food, which brings bad factors to people's life and health, makes people prone to aging, and easy to get chronic diseases. People are looking for a cast iron electric rice cooker gall, or clay pot gall. However, pure iron pans are prone to rust, and it is not advisable to have loose holes. Nixing pot gall is easy to break. Also have recently pot gall to be coated with non-stick layer, spray on the surface after making coating with some chemical raw materials and make. The outer surface of this non-stick layer looks good and fee...

Examples

Embodiment 1

[0019] Embodiment 1, a pig iron stone electric rice cooker gall and its production method, including pot ears, pot body, inner cavity, pot bottom, stone powder layer, inner lining layer, body, enamel layer, characterized in that the body (7) The outer layer is an enamel layer (8), the inner lining layer (6) is inside the body (7), and the stone powder layer (5) is outside the inner lining layer (6). The stone powder layer (5) contains quartz, silicate, and granite. Between the lining layer (6) and the enamel layer (8) is the body (7). There are more than one layer of lining layer (6) in the body (7). More than one layer of stone powder layer (5) is arranged in the body (7).

[0020] The production process and equipment are: molten iron melting in intermediate frequency furnace → double sand mold forming → sand cleaning by shot blasting machine → machining → annealing treatment → spraying daily-use enamel material on the outer diameter of the pot → spraying metal and stone bo...

Embodiment 2

[0021] Example 2, the pot ears (1) are turned outward at the top port of the pot body (2), and the pot body (2) is made as follows: ①The molten iron is smelted in an intermediate frequency electric furnace and formed by a double-sand mold process. ②Sand blasting with a shot blasting machine. ③ Machine tool processing. ④ Annealing oxidation treatment is 900 ℃. ⑤The outer diameter of the pot is sprayed with daily-use enamel paint with a thickness of 0.5mm, and the inner layer is sprayed with multiple layers of stone powder adhesive material with a thickness of 0.3mm, and then dried at 150°C. ⑥Use a ball mill to grind the stone to 150 mesh, add 0.1 borax and 0.5 parts by mass of soda ash and clay, stir and spray the inner layer evenly, with a thickness of about 1 mm. ⑦ The inner pot is dried at 800°C. The structure of the pot is: the outer layer of the main body (7) is an enamel layer (8), the inner lining layer (6) is inside the main body (7), the outer lining layer (6) is a ...

Embodiment 3

[0022] Example 3, referring to the production process and structure of Example 1 and Example 2, the outer enamel layer (8) is sprayed on the outer diameter of the body (7) pot for 3 to 20 minutes, and then the inner lining layer (6) is sprayed on the inner diameter of the pot , the inner lining layer (6), spraying with metal powder for 3 to 20 minutes, and then spraying the stone powder layer (5) to the adhesive state, and then baking at a temperature of 800°C.
