A kind of aluminum-titanium-boron-aluminum-magnesium alloy tread block casting material and its production method

Abstract

The invention relates to a segmental mold aluminum-titanium-boron aluminum-magnesium alloy pattern block casting material and a production method thereof. According to the technical scheme, the casting material is prepared from the following components in parts by weight: 99.85% of pure aluminum ingots, 0.20% of silicon, 0.10% of iron, 0.10% of copper, 0.10% of manganese, 3.80% of magnesium, 0.01% of chrome, 0.0050% of nickel, 0.0047% of zinc, 0.000108% of beryllium, 0.0032% of bismuth, 0.0108% of lithium, 0.00063% of sodium, 0.0030% of titanium alloy powder T15.2, and 0.0025% of aluminum-titanium-boron ALTi5B1. The casting material has the beneficial effects that: 1, a die casting is precise in cooling shrinkage contour curved surface and good in surface precision, and has no defects such as pinholes, shrinkage porosity, cold shut, and the like; 2, pattern edges and corners are clear, and the surface smoothness is good; 3, the casting material is corrosion-resistant, does not stick scourings, and resists blast cleaning; 4, the casting material is high in strength, good in toughness, and uneasy to have plastic deformation after being machined; 5, the casting material is wear-resistant, long in service life, and resists die opening-closing impact; and 6, an aluminum-titanium-boron aluminum-magnesium alloy is taken as an independent ingredient, the element proportioning of the alloy is accurate, and the rate of finished products is high, thereby reducing the cost spending of enterprises.

Description

technical field [0001] The invention relates to a radial tire split mold casting material, in particular to a split die aluminum-titanium-boron-aluminum-magnesium alloy pattern block casting material and a manufacturing method. Background technique [0002] Radial tires are the standard to measure the technical modernization level of a country's automobile tire industry, and have become the development direction of the automobile tire industry in today's world. As a special mold for tire vulcanization, the high-end radial tire active mold is mainly a semi-steel cast aluminum alloy pattern block, which is an ideal material for the tire mold pattern block application. my country is rich in rare earth resources, ranking first in the world. It is of great significance to study the behavior of rare earths in the solidification process of aluminum alloys and carry out basic research on the application of rare earths in metals and alloys for the development of rare earth resources...

Problems solved by technology

[0003] At present, the main problems of the domestically produced tire mold aluminum pattern block are: the casting aluminum alloy surface is unstable in shrinkage, easy to deform, there are needle voids and casting defects, low hardness, the aluminum pattern block mold is not resistant to opening and closing, impact and sliding, and it is used for sandblasting Short life, etc., resulting in increased costs for tire companies
