specific Embodiment approach 1

[0015] Embodiment 1: The method for manufacturing a high-strength anti-rust aluminum alloy flat ingot described in this embodiment is specifically carried out according to the following steps:

[0016] 1. Melting: according to the mass fraction of 0.65% ~ 1.0% Si, 1.4% ~ 1.8% Mn, 1.3% ~ 1.7% Zn, 0.05% ~ 0.2% Zr, 0.02% ~ 0.04% Ti and the balance is Al. Take pure aluminum ingots, Al-Si master alloys, Mn additives, pure Zn ingots, Al-Ti wires and Al-Zr master alloys, and melt them in a natural gas furnace at a temperature of 720°C to 760°C to obtain pure aluminum ingots, Al- Si master alloy, Mn additive, pure Zn ingot, Al-Ti wire and Al-Zr master alloy are completely melted, and then the melt is stirred at a temperature of 720°C to 760°C and a stirring speed of 10r / min to 15r / min 5min~10min, the aluminum alloy melt is obtained;

[0017] 2. Forming: import the molten aluminum alloy prepared in step 1 into a static furnace, refine it at a temperature of 710°C to 730°C and under th...

specific Embodiment approach 2

[0026] Embodiment 2: This embodiment differs from Embodiment 1 in that: in step 2, an automatic temperature control system is used to control the temperature of the semi-continuous casting, and the temperature control accuracy of the automatic temperature control system is ±5°C. Others are the same as in the first embodiment.

specific Embodiment approach 3

[0027] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is that the cooling water flow is first controlled to 50m in the semi-continuous casting method described in step two 3 / h, until the casting length is 100~150mm, the cooling water flow rate is adjusted to 80m 3 / h. Others are the same as in the first or second embodiment.

[0028] In this embodiment, low water flow is used at the beginning of the casting production process, and the water flow is increased when the ingot is produced to 100mm-150mm, so as to slow down the tendency of large shrinkage at the beginning of the ingot and ensure the shape of the ingot.

Abstract

The invention discloses a manufacturing method of a high-strength antirust aluminum alloy slab ingot and relates to a manufacturing method of an aluminum alloy slab ingot. The manufacturing method solves the problems that a core of an existing composite material is mainly a 3003 alloy, but the 3003 alloy hardly meets the requirements of the current market on the high-performance composite material due to low alloying degree and low strength. The method comprises the following steps: 1, melting, and 2, forming, so that the high-strength antirust aluminum alloy slab ingot is obtained. The manufacturing method is used for manufacturing the high-strength antirust aluminum alloy slab ingot.

Description

technical field [0001] The invention relates to a method for manufacturing an aluminum alloy slab. Background technique [0002] Due to the characteristics of strong strength, good heat dissipation and light weight and anti-rust, composite materials are widely used in the manufacture of mechanical equipment, especially in special equipment, and the scope of use is becoming more and more extensive. The core of the composite material has always been 3003 alloy. With the development of the market, the performance requirements of the composite material are getting higher and higher. However, the 3003 alloy has low alloying degree and low strength. Therefore, it is difficult to meet the current market requirements. Requirements for high-performance composite materials. Contents of the invention [0003] The invention aims to solve the problem that the core of the existing composite material is mainly 3003 alloy, and the 3003 alloy is difficult to meet the requirements of the c...
