Problems solved by technology

[0002] At present, the burners of gas stoves are all made of cast iron and copper. It is difficult to achieve the ideal practical effect in terms of structural design and processing accuracy, and the cost of materials and processing is high.
However, if the conventional aluminum alloy burner burns at a high temperature for a long time or after a long time of use, the conventional aluminum alloy burner will appear blistering, deformation, or corrosion

Embodiment 1

[0009] Example 1: Put 100 parts of aluminum ingots with a purity of 99.5% in parts by weight into a furnace for melting, then add 3.0 parts of copper, 3.0 parts of silicon, 0.9 parts of manganese, 0.5 parts of iron, 0.5 parts of nickel, magnesium 0.15 parts, 0.05 parts of zinc, 0.1 parts of chromium, 0.02 parts of zirconium, 0.02 parts of titanium and 0.05 parts of antimony. Die-casting with a cold chamber die-casting machine with three-stage injection. The mold design cavity adopts center feeding, and the die-casted furnace head is placed in an oven for heat treatment: bake at 220°C for 1 hour, then bake at 280°C for 2 hours, and then Bake at 350°C for 3 hours, then bake at 380°C for 4 hours, keep warm for 2 hours and then open the oven to cool the workpiece naturally, and finally finish it.

Embodiment 2

[0010] Example 2: Put 100 parts of aluminum ingots with a purity of 99.5% in parts by weight into a furnace for melting, then add 4.0 parts of copper, 5.0 parts of silicon, 1.5 parts of manganese, 0.7 parts of iron, 1.0 parts of nickel, and magnesium 0.25 parts, 0.1 parts of zinc, 0.15 parts of chromium, 0.05 parts of zirconium, 0.05 parts of titanium and 0.1 parts of antimony. Die-casting with a cold chamber die-casting machine with three-stage injection. The mold design cavity adopts center feeding, and the die-casted furnace head is placed in an oven for heat treatment: bake at 220°C for 2 hours, then bake at 280°C for 4 hours, and then Bake at 350°C for 6 hours, then bake at 380°C for 8 hours, keep warm for 8 hours and then open the oven to cool the workpiece naturally, and finally finish it.

Embodiment 3

[0011] Example 3: Put 100 parts of aluminum ingots with a purity of 99.5% in parts by weight into a furnace for melting, then add 3.5 parts of copper, 4 parts of silicon, 1.2 parts of manganese, 0.6 parts of iron, 0.8 parts of nickel, magnesium 0.2 parts, 0.08 parts of zinc, 0.12 parts of chromium, 0.03 parts of zirconium, 0.03 parts of titanium and 0.08 parts of antimony. Die-casting with a cold chamber die-casting machine with three-stage injection. The mold design cavity adopts center feeding, and the die-casted furnace head is placed in an oven for heat treatment: bake at 220°C for 1.5 hours, then bake at 280°C for 3 hours, and then Bake at 350°C for 5 hours, then bake at 380°C for 6 hours, keep warm for 5 hours, then open the oven to cool the workpiece naturally, and finally finish it.

Abstract

The invention discloses an alloy of a high temperature resisting aluminum alloy furnace end and a manufacturing method thereof. The alloy comprises the following elements in parts by weight: 100 parts of aluminum, 3.0-4.0 parts of copper, 3.0-5.0 parts of silicon, 0.9-1.5 parts of manganese, 0-0.7 part of ferrum, 0-1.0 part of nickel, 0-0.25 part of magnesium, 0-0.1 part of zinc, 0-0.15 part of chromium, 0-0.05 part of zirconium, 0-0.05 part of zirconium, 0-0.1 part of antimony and 0-0.75 part of impurities in sum. The manufacturing method comprises the steps of: melting, feeding, smelting and stirring, constant temperature processing, pressure casting, thermal treatment and finishing. The invention has the advantages of solving problems of easiness of foaming, deformation, erosion and the like of the conventional aluminum alloy furnace end efficiently and having reasonable prescription, simple manufacturing method and the like.

Description

technical field [0001] The invention relates to a high-temperature-resistant aluminum alloy burner material for cookers and a manufacturing method thereof. Background technique [0002] At present, the burners of gas cookers are all made of cast iron and copper. It is difficult to achieve the ideal practical effect in terms of structural design and processing accuracy, and the cost of materials and processing is high. However, after using a conventional aluminum alloy burner under high-temperature combustion for a long time or after a long time of use, blistering, deformation, or corrosion will occur in the conventional aluminum alloy burner. Contents of the invention [0003] The object of the present invention is to provide a high-temperature-resistant aluminum alloy stove head alloy with reasonable formula and simple manufacturing method, which can effectively solve the problems of easy foaming, deformation and corrosion of conventional aluminum alloy stove heads, and i...
