Production process for aluminum pot with composite bottom

Abstract

The invention discloses a production process for an aluminum pot with the composite bottom. The production process comprises the following steps of material selecting, smelting of an aluminium ingot,preheating of a die-casting mould, preheating of a magnetic conducting piece clamp, vacuumizing of the die-casting mould, die-casting forming, blank treatment and finish machining. After forming, thepot bottom is provided with a thread, a magnetic conducting piece is sunken in the pot bottom, the outer surface of the magnetic conducting piece is exposed, and the outer surface of the magnetic conducting piece and the surface of the pot bottom have the gap fall head of 0.2-1.5 mm so that the magnetic conducting piece can do not make direct contact with an induction cooker. The production process is simple, the investment cost of the mould and large equipment is reduced, the defects of deformation, indentations, pits and the like of a finished product are avoided, and the manpower cost and production energy consumption are reduced; and deformation of the pot bottom is small in the cold state and the hot state, the heat conduction surface is increased through the thread pot bottom, and thus energy saving is better achieved.

Description

technical field [0001] The invention belongs to the technical field of casting, and in particular relates to a production process of an aluminum pot with a composite bottom. Background technique [0002] Non-stick aluminum die-casting pans have the characteristics of fast heat conduction, light weight and less oily smoke, especially the flat-bottomed non-stick aluminum pans can be used in various stoves such as gas stoves or induction cookers after double-bottom technology, and are favored by domestic and foreign customers. . The current status of the industry is: 1. Under the technical conditions of the double-bottom aluminum pot in the industry, if the magnetic conductivity and thermal efficiency and power factor are guaranteed, usually after the combination of the two materials, the thermal deformation of the bottom concave will be unstable and cannot meet the requirements. LGA bottom concave test requirements; 2. A lot of molds and equipment are required to be investe...
