[0003] The existing grid continuous casting mold needs to control the temperature of the mold during production to ensure that the quality of the grid production is guaranteed. In the grid continuous casting production, the mold is generally controlled by a heat conducting oil circulation system. When the mold is overheated, the heat conducting oil needs to be cooled and circulated. When the equipment starts, the heat conducting oil needs to heat the mold to make the temperature of the continuous casting mold meet the production requirements. However, the existing heat conducting oil circulation system cannot meet the temperature control requirements of the continuous casting mold. At the same time, after the grid is produced, the grid needs to be cooled and the surface oil stains need to be cleaned to ensure that the quality of the grid production is guaranteed. In the grid continuous casting production, the grid is generally cleaned and cooled by circulating water.
