Abstract
The utility model discloses a furnace bottom structure of a ferro-nickel furnace with a power of more than 16500 KW, which comprises a furnace-bottom steel plate layer, an asbestos plate layer, a refractory grain layer, a refractory brick layer, a ramming material layer and a magnesite brick layer, wherein the asbestos plate layer is laid on the furnace-bottom steel plate layer, the refractory grain layer is laid on the asbestos plate layer, the refractory brick layer is laid on the refractory grain layer, the ramming material layer is laid on the refractory brick layer, and the magnesite brick layer is laid on the ramming material layer. The furnace-bottom steel plate layer and the outer wall of a furnace body are connected together in a welding or removable installation mode so as to form a shell of the furnace body. The ramming material layer is composed of 2-5 layers of ramming materials with different magnesium oxide contents. The furnace bottom structure disclosed by the utility model has the advantages that the ramming material layer forms an integral sintering layer under the condition of high-temperature sintering, and no gap exists, so that under the action of alternate cooling and heating, cracks are uneasily formed, thereby avoiding that molten iron erodes the furnace body, prolonging the service life of the furnace bottom structure of the ferro-nickel furnace, and reducing the maintenance and smelting costs.
