Abstract

The present invention relates to a high-strength and high-toughness die-casting aluminum alloy, and a preparation method therefor and the use thereof. The alloy comprises 7.0-9.5% of Si, 0.4-0.9% of Mn, 0.15-0.35% of Mg, 0.1-0.4% of Nb, 0.1-0.4% of V, 0.10-0.25% of Ti, 0.03-0.05% of Sr, no more than 0.30% of Fe, and no more than 0.05% of inevitable impurity elements, with the balance being Al. The alloy shows relatively high fluidity and good thermal cracking resistance and mold sticking resistance, has high strength and elongation in an as-cast state, has higher mechanical properties and an elongation of no less than 10% after undergoing a heat treatment, and meets the performance requirements of die-cast structural parts for automobiles. Switching to the alloy can be rapidly achieved on an existing die-casting production line, without the need for reforming and upgrading of existing smelting and die-casting apparatuses, such that the production cost is reduced.

Abstract

A refiner for aluminum alloy, aluminum-niobium-titanium-boron, a method for preparing refiner, a method for preparing aluminum-niobium-titanium-boron, and a method for preparing aluminum-niobium-boron. The refiner is AlNb(X)B, X being either of lanthanum and cerium. When X is lanthanum, potassium fluoniobate, aluminum-lanthanum alloy, potassium fluoborate and aluminum are provided and put into a reaction furnace for heating reaction, a fluoroaluminate generated after the reaction is poured out and then casting is performed on a reaction product, thereby obtaining aluminum-niobium-lanthanum-boron; and when X is cerium, potassium fluoniobate, aluminum-cerium alloy, potassium fluoborate and aluminum are provided and put into the reaction furnace for heating reaction, a fluoaluminate generated after the reaction is poured out and then casting is performed on a reaction product, thereby obtaining aluminum-niobium-cerium-boron. In the preparation method, potassium fluoniobate is used as a niobium source, so that low price and high economical efficiency are achieved. For the prepared refiner, the reaction temperature is low and within the range of 700-900°C, so that the burning loss of molten aluminum is small and reaction is adequate, and the reaction time is 10-60 minutes, so that the efficiency is high.

Abstract

A preparation method for an aluminum-niobium master alloy. The preparation method comprises the following steps: proportioning reactants, i.e., potassium fluoniobate and aluminum, according to an aluminum-niobium master alloy comprising 5.0-30.0 wt% of niobium and the balance of aluminum, placing the two in a reaction furnace, mixing and heating same for a reaction, enabling a fluoroaluminate generated after the reaction to float on the surface of a reaction product in the reaction furnace, pouring out the fluoroaluminate, and then casting the reaction product, so as to obtain the aluminum-niobium master alloy. By means of the preparation method, an aluminum-niobium master alloy with a relatively low niobium content can be prepared.

Abstract

The invention relates to the field of aluminum wheel casting molds, and more particularly relates to a closed-loop control method and system for a mold temperature in a wheel casting process. The control method includes: step 1, acquiring data, that is, acquiring a plurality of mold position temperatures, and cooling pipeline opening and closing signals in a target wheel casting process according to a fixed frequency; step 2, storing, based on acquired mold opening and closing signals of casting equipment, the acquired data in a database in the form of a unique ID according to a single wheel casting process; step 3, calculating new process parameters based on the acquired plurality of position temperatures and time; and step 4, integrating the calculated process parameters, and issuing the process parameters to a PLC of a casting equipment to perform new casting. According to the invention, the temperature control parameters are calculated based on the acquired temperature data and time process to form the temperature control process of the casting process, which solves the technical problem of significant fluctuations in the quality of the low-pressure casting process of aluminum wheels and improves casting stability and yield.

Abstract

An aluminum alloy material smelting device comprises a furnace and a packing device with a packing basket, a stirring shaft connected with the packing basket and a stirring head connected with the bottom of the packing basket. The stirring head comprises a plurality of stirring blades with one end connected with the bottom of the packing basket and another end connected with each other on the central axis of the packing basket. The side wall of the packing basket is provided with a liquid passage hole to exchange liquid with the solution outside the packing basket. By rotating the stirring head, a solution vortex accelerating the diffusion of added elements can be formed only under the stirring head, which will not damage the covering film formed on the surface of aluminum alloy. Thus the scum on the surface is effectively prevented from being involved in the solution again.

Abstract

The application discloses a preparation method for an aluminum alloy cavity casting filled with special-shaped foamed aluminum. The preparation method includes: preparing special-shaped foamed aluminum in a first mold by adopting a powder metallurgy foaming method; fixing the special-shaped foamed aluminum coated with the soldering flux in a second mold after the special-shaped foamed aluminum is coated with soldering flux; and casting by using molten aluminum alloy. According to the preparation method for the aluminum alloy cavity casting filled with the special-shaped foamed aluminum, the overall strength of the casting can be improved while the wall thickness of the casting is reduced to meet the requirement that the overall quality of the casting is not increased.
