Abstract

The invention provides a manufacturing process of metal doors and windows, which includes the following steps: 1. Preheat the furnace for 3-5 hours, and the preheating temperature is 600-800°C; 2. Pour copper and silicon into the furnace in sequence. , magnesium, manganese and zinc, while rapidly raising the temperature of the furnace to 1500‑1800 ° C, heating for 25‑40 minutes, after the metal is completely melted, keep it warm for 5‑10 minutes to obtain mixed metal 1; 3. Add rare earth to mixed metal 1 and stir At the same time, reduce the temperature of the furnace to 700-800°C and heat for 20-25min to obtain the mixed metal II; Fourth, add nickel, chromium, titanium, boron, zirconium and strontium to the mixed metal II in sequence, and then transfer to the refining furnace for further refining Refining, the refining temperature is 700-850°C, refining for 45-65min, to obtain material 1; 5. Pour material 1 into the mold and cool to room temperature, then perform quenching and hot rolling to obtain material 2; 6. Material 2 is processed Cutting and grinding can be done. The invention improves the toughness and rigidity of doors and windows, and at the same time improves the acid resistance, alkali resistance and high temperature resistance of metal doors and windows.

Description

technical field [0001] The invention belongs to the technical field of door and window manufacturing, and in particular relates to a metal door and window manufacturing process. Background technique [0002] As people's living and home styles become more and more diverse, the demand for living and home styles has also increased. Among them, the improvement of building quality requirements is particularly prominent, and the requirements for building doors and windows are the most prominent. The doors and windows used today are made of metal, There are several kinds of plastic, wood, etc., so the material for making doors and windows has become the main research object. [0003] Material is an important pillar of today's science and technology, and it is particularly important because it is the foundation of human society development and all science and technology. The degree of technological development of materials will directly affect the transformation of productivity. The...
