In order to make the iron outlet is often in a normal state, in addition to the iron outlet in the use of a certain period of time (larger capacity of mineral heat furnace outlet usually used two to three weeks), need to be repaired. Repair method Methods are as follows:
1. Seal the iron outlet: after the iron, with a larger dry loach plug as deep as possible, and then with electrode paste or with more electrode paste mud ball plug.
2. Sealed iron outlet, after 15 to 25 hours, began to use the electric shock rod to burn large iron outlet, should be filled with the previous repair of the electrode paste all burned off, burned deep, burned large.
3. After burning the iron outlet, first use the electrode paste to pave the flow of iron groove. Then put a steel pipe equal to the diameter of the furnace eye on the normal position of the iron outlet, as shown in Figure 10.
4. fill the electrode paste and pounded (can be outside the mouth of the first two to three layers of clay brick layer, that is, the mouth of the iron arch bricks), and then, the side of the clay side of the electrode paste and pounded, until filled until. To be sintered by the electrode paste sink, and then fill the electrode paste, so that it is sintered with the outlet carbon brick into one.
5. Iron out of the mouth of the flow channel carbon brick, generally in the repair of iron out of the mouth before or being repaired when replaced. Replacement of carbon bricks, pay special attention to the outlet carbon bricks between the seam wash out of the electrode paste knotting situation. If the outlet carbon brick can continue to use, it is not necessary to replace, you can lay a layer of heated electrode paste, by wood (or hot slag) baking caramelization, in a layer of river sand.
In the process of repairing the iron outlet and for a period of time before use, the iron outlet has to be placed under the iron package.
