Problems solved by technology

However, in order to obtain a good anti-rust layer in ordinary nitriding treatment, the treatment temperature is usually high, which easily softens or melts the metal of the double bottom layer, so that the double bottom plate and the pot body cannot be firmly combined, and when the nitriding treatment temperature is lowered , the time required for nitriding treatment is very long, for example, it usually takes more than 10 hours, and the obtained anti-rust layer is thin and the anti-rust ability is also poor, which not only makes the manufacturing cycle too long and the cost is too high, but also the nitriding treatment The effect is also very poor, unable to meet the needs of users

Abstract

The invention discloses a composite bottom pot body and a manufacturing method thereof. The composite bottom pot body (100) comprises a pot bottom wall (1) and a composite bottom sheet (3) arranged at the bottom of the pot bottom wall. The pot bottom wall and the composite bottom sheet A compound bottom cavity (5) is formed therebetween, the pot bottom wall and the compound bottom sheet are fixedly connected by a connecting piece (2), and the compound bottom cavity is also filled with a sintered compound bottom cavity filling material (4). The manufacturing method includes connecting the double bottom sheet at the bottom of the bottom wall of the pot through a connecting piece; welding and sealing the peripheral edge (31) of the double bottom sheet and the outer peripheral wall of the pot body; filling the compound bottom cavity between the reciprocating bottom sheet and the pot body. The bottom cavity filling material; finally, the pot body with the double bottom sheet and the double bottom cavity filling material is heated. The cookware of the invention can thicken the bottom of the pan, improve the heat storage performance and thermal conductivity of the bottom of the pan, improve the temperature uniformity of the bottom of the pan, reduce the generation of oil fume, and improve the product quality and user experience. The manufacturing method is simple, practical and low in cost, and can be used in mass production with high efficiency.

Description

technical field [0001] The invention belongs to the field of cooking utensils, and in particular relates to a composite bottom pot body and a manufacturing method thereof. Background technique [0002] Stainless refined iron pots are mostly made of single-layer iron plate or steel plate, and then rust-proof treatment is carried out by nitriding, that is, nitriding treatment. like figure 1 As shown, since the pot body 100, especially the pot bottom wall 1 with a diameter D as the main heating area is a single-layer, thin and made of iron or steel material with poor thermal conductivity, there is a general problem of poor thermal conductivity. It is easy to deform after heating, and it is easy to produce oil fume and many other problems, the product quality is low, and the user experience is poor. [0003] For problems such as uneven heat conduction and easy deformation, the method of re-bottoming of the pot is also considered in the research. For example, the composite bott...
