Problems solved by technology

[0003] However, stainless steel, aluminum, iron and other materials also have their limitations in the application of kitchen utensils and small household appliances, which are reflected as follows: ①Due to the characteristics of conventional metal materials such as stainless steel, aluminum, iron, etc. The temperature of the material is always rising during the process, and it can reach hundreds of degrees Celsius in a few minutes, while the general cooking temperature only needs to be 100°C to 200°C; in addition, conventional metal materials such as stainless steel, aluminum, and iron, The material itself does not have non-stick properties. Non-stick coatings are often used in the kitchenware and small household appliance industries to solve the non-stick problem of products. However, the suitable temperature for use of non-stick coatings is below 260°C. When the temperature exceeds 260°C, the coating It will be in an unstable state and will release harmful substances at high temperatures. Therefore, the anti-dry function of non-stick pans using conventional metal materials such as stainless steel, aluminum, and iron has not been well improved, mainly because the pan material does not have a constant temperature. requirements, not controlled within the appropriate temperature range
At the same time, there is no ideal material suitable for non-stick pans on the market at present.

Embodiment 1

[0042] Such as Figure 1~4 As shown, this embodiment 1 discloses a preparation method of a constant temperature material, which includes the following steps:

[0043] Step 1, electric arc furnace smelting: direct reduced iron is used as the main raw material. The first electric arc furnace adopts an eccentric furnace bottom structure, and its main function is to melt direct reduced iron. The molten steel is dephosphorized, and the temperature of the molten pool reaches 1560 ° C ~ 1580 ° C;

[0044] Step 2, electric arc furnace alloying: the second electric arc furnace adopts a steel spout structure, and the electric furnace is smelted with oxygen blowing operation to remove part of the carbon in the molten steel, and the alloy of 60% to 70% by weight of stainless steel is added to the electric furnace to carry out The molten steel is alloyed, and the temperature of the molten pool reaches 1600 ° C ~ 1660 ° C;

[0045] Step 3, refining in AOD furnace: blending the molten stee...

Embodiment 2

[0089] In this embodiment 2, when the melt is mixed and stirred, a stirrer is used for stirring; the stirrer includes a frame 1 and a first container 2 arranged beside the frame 1; the top of the first container 2 is provided with an opening; The first container 2 is provided with a cavity communicating with the opening; the frame 1 is provided with a stirring device that can move up and down along the frame 1; the stirring device includes a stirring device for stirring the solution assembly, a driving device 3 for controlling the movement state of the stirring assembly, and a second container 4 for loading the melt to be mixed; the second container 4 communicates with the stirring assembly through a pipeline.

[0090] In this embodiment 2, in order to accurately adjust the height of the stirring device relative to the first container 2, so as to achieve the expected stirring effect, there is also a lifting device on the frame 1; the lifting device includes a vertically arrange...

Abstract

The invention discloses a preparation method for a constant-temperature material. The preparation method for the constant-temperature material comprises the following steps: weighing stainless steel;taking graphene; preparing a carbon powder; adding rare-earth elements and metals; and obtaining the constant-temperature material through mixing, high-temperature smelting and crystallization. Because the main components of the constant-temperature material are composed of the graphene, the carbon powder, the rare-earth elements and a small amount of common metal elements, compared with a stainless steel kitchenware material, the constant-temperature material does not release heavy metal elements, have no standard-exceeding problem of heavy metals, is more green and environment-friendly, andachieves a higher guarantee on healthy diet; and according to the preparation method for the constant-temperature material, other auxiliary devices do not need to be added, and temperature control canbe realized through the own newest function of the material, and in particular, the preparation method for the constant-temperature material is more prominent in application advantage in the fields of non-stick pans and smokeless pans, also has great advantages in the aspects of material performance, product structure performance, effect popularization, product production cost and the like, and is of great use significance to the field with a requirement on a temperature, for example, the kitchenware industry or the small appliance industry.

Description

technical field [0001] The invention relates to the technical field of constant temperature materials, in particular to a preparation method of constant temperature materials. Background technique [0002] At present, conventional metal materials such as stainless steel, aluminum, and iron are often used in the kitchenware industry and small household appliance industry. Due to frequent physical contact, stainless steel materials are more widely used, mainly because stainless steel materials have ① Thin and dense chromium-rich oxidation on the surface of stainless steel Membrane, has good corrosion resistance, stainless steel has corrosion resistance, enhanced strength, steel deformation is not easy to break and environmental protection performance, not easy to rust, and has good ductility and toughness. It is suitable for use in harsh environments (wet, acid-base and other indoor and outdoor environments). ②Stainless steel can work safely under high temperature for a long t...
