Alloy for aluminum alloy cutting saw and preparation method of alloy

Abstract

The invention discloses an alloy for an aluminum alloy cutting saw. The alloy comprises the following raw material components in percentage by mass: 3.2% to 3.9% of C, 2.0% to 3.0% of Si, less than or equal to 0.2% of Mn, less than or equal to 0.015% of P, less than or equal to 0.015% of S, less than or equal to 0.8% of Cu, less than or equal to 1% of other elements and the balance of Fe, and the sum of the contents of the components is 100%. The invention also discloses a preparation method of the alloy. The preparation method comprises the following steps that 1, bread iron containing 4.5% by mass of carbon and 1.5% by mass of silicon, common waste steel containing 0.3% by mass of carbon, 75 ferrosilicon containing 75% by mass of silicon and 25% by mass of iron are selected, and 3.5% by mass of C, 2.5% by mass of Si and the balance of Fe are weighed; 2, the raw materials are melted at high temperature, and a nucleating agent and a spheroidizing agent are added; 3, casting is achieved to obtain a casting; and 4, the casting is subjected to salt bath after heat preservation. According to the alloy for the aluminum alloy cutting saw and the preparation method of the alloy, heat generated in the aluminum material machining process is greatly reduced, the cutter sticking phenomenon is avoided, and the service life of the cutting saw is prolonged.

Description

technical field

[0001] The invention belongs to the technical field of sawing materials, and in particular relates to an alloy used for aluminum alloy sawing, and also relates to a preparation method of the alloy used for aluminum alloy sawing. Background technique

[0002] With the increase of human demand for aluminum products, aluminum processing has become an inevitable procedure for the development of aluminum alloy products. However, unlike cutting other metals such as steel, aluminum alloys are prone to "knife sticking" during cutting. The problem of aluminum shavings sticking to the knife will directly lead to a decline in the final sawing quality of aluminum, and the running state of the saw blade will also be directly affected. At present, high-speed steel is used for aluminum alloy sawing blades. When the saw blade cuts aluminum at high speed, the high friction coefficient between the saw blade and the aluminum alloy generates huge heat on the contact surface, an...
