Problems solved by technology

At present, there is no uniform standard test method and equipment for the fluidity of magnesium alloys. Most of them inject the melt into the mold cavity, and measure the fluidity of the alloy by measuring the length of the melt filling in the cavity. The test conditions have not been standardized and standardized. This method is only a qualitative detection and comparison of the flow properties of the test alloys, and it cannot be quantitatively identified as the intrinsic properties of different alloys.

Abstract

The invention relates to the field of pressure casting, in particular to an alloy flowing property detection device. The device mainly comprises a sprue gate and a flowing property testing mold; a funnel-shaped descending port is formed below the sprue gate; the periphery of the descending port is wrapped with an electric heating pipe, a heat preservation material is arranged outside the electricheating pipe, the descending port is provided with a round port, the flowing property testing grinding tool is arranged below the descending port and forms a right angle with the whole pouring port, aflowing groove is formed in the flowing property testing grinding tool, and the electric heating pipe and the heat preservation material are arranged around the flowing groove. The liquidity can be judged and evaluated more accurately and quantitatively, normalization and standardization are improved, and the liquidity of the alloy is shown by measuring the solidification length of the alloy after flowing in the launder through the length measuring device.

Description

technical field [0001] The invention relates to the field of pressure casting, in particular to an alloy fluidity detection device. Background technique [0002] The flowability of the alloy is the main assessment index of the project, and it is also the main performance index of the target alloy, so the detection of the flowability of the alloy is particularly important. At present, there is no uniform standard test method and equipment for the fluidity of magnesium alloys. Most of them inject the melt into the mold cavity, and measure the fluidity of the alloy by measuring the length of the melt filling in the cavity. The test conditions have not been standardized and standardized. This method is only a qualitative detection and comparison of the flow properties of the test alloys, and it cannot be quantitatively identified as the intrinsic properties of different alloys. Contents of the invention [0003] In order to solve the above technical problems, the present inve...
