The invention relates to a homogenization heat treatment process of a large-size magnesium alloy ingot, belonging to the technical field of magnesium alloy material preparation. The process is characterized by heating a large-size magnesium alloy ingot to 320-350 DEG C at a heating rate of 10-30 DEG C / min and then heating the large-size magnesium alloy ingot to 410-430 DEG C at a heating rate of 12-27 DEG C / h, insulating the large-size magnesium alloy ingot and then cooling the large-size magnesium alloy ingot to the room temperature at a cooling speed of 2-10 DEG C / min, thus obtaining the finished product, wherein the diameter phi of the large-size magnesium alloy ingot is not less than 220mm. The process has the beneficial effects that quick heating is carried out at the early stage of homogenization to release the casting stress to prevent growth of grains in the homogenization process; later, slow heating is carried out till the homogenization temperature to ensure that all the parts are heated uniformly to prevent overburning; then cooling is carried out at a cooling speed of 2-10 DEG C / min till the room temperature is reached, thus preventing cracking due to too quick cooling and also avoiding precipitation strengthening, which is unfavourable for subsequent deformation, due to too slow cooling; dendritic segregation of the large-size magnesium alloy ingot treated by the process is basically eliminated and the components in various parts of the large-size magnesium alloy ingot are uniform; besides, the equipment used in the process is a conventional resistance furnace, is mature in process and is safe and reliable.
