Supporting and moving division bar arrangement process special for heat treatment of aluminum alloy round ingot

Abstract

The embodiment of the invention discloses a supporting and moving division bar arrangement process special for heat treatment of aluminum alloy round ingots. The aluminum alloy round ingots are supported and stacked by adopting moving division bars and fixed division bars. The method comprises the following steps that S001, the fixed division bars are placed in the center of a material bearing table, and then movable division bars with the same number are placed at the two sides of the fixed division bar; then the aluminum alloy round ingot is placed on the division bars; S002, the fixed division bars are placed on the whole upper surface of the placed aluminum alloy round ingot, or the division bars are placed according to the mode in the step S001; then the aluminum alloy round ingot is placed on the division bars; S003, the step S002 is repeated until the preset stacking layer number is reached; and S004, the stacked aluminum alloy round ingots are subjected to heat treatment. By the adoption of the method, the contact area and friction force between the bearing movable division bars and a bearing point can be reduced, and damage such as extrusion marks on the surface of the aluminum alloy round ingot caused by relative displacement between the bearing platform and the division bars due to heating expansion caused by temperature change in the heat treatment process is avoided.

Description

technical field [0001] The invention relates to the field of heat treatment of aluminum alloy round ingots, in particular to a process for arranging support and moving spacers dedicated to the heat treatment of aluminum alloy round ingots. Background technique [0002] Inhomogeneity and stress are formed during the casting and crystallization of aluminum alloy round ingots, so a homogenization heat treatment process is required after the casting is completed. Before the ingots enter the homogenizing furnace, in order to ensure that each ingot is heated uniformly in the furnace and to avoid indentation of the ingots during the homogenization process, it is necessary to stack and stack the ingots evenly at intervals. At present, the bottom of the ingot stack in my country is supported by fixed spacers or rigid brackets. During the heat treatment process, there are generally deep extrusion marks on the surface of the contact between the aluminum alloy round ingot and the bracke...

Problems solved by technology

[0003] In order to solve the technical problem that the existing aluminum alloy round ingot stacking process is easy to produce indentation on the surface of the round ingot, the embodiment of the present invention provides a special support and moving spacer arrangement process for the heat treatment of aluminum alloy round ingots, which can reduce the support Move the contact area and friction between the spacer and the bearing point to avoid damage such as extrusion marks on the surface of the aluminum alloy round ingot due to thermal expansion due to temperature changes and relative displacement of the bearing table and spacer during the heat treatment process
