1. The weighing must be accurate. Various materials must be weighed according to the specified quantity, with small errors. If the weighing is inaccurate, the furnace condition is not easy to grasp, and waste products may even be produced. Therefore, the batching work should be careful, and the accuracy of the weighing tool should be checked frequently. If problems are found, they should be adjusted or repaired in time.
2. Follow the prescribed order of ingredients to make the ingredients evenly mixed. The specific gravity of the coke pile is about 0.5 to 0.6. The bulk density of silica is about 1.5 to 1.6, and the bulk density of scrap steel is 1.8 to 2.2. The proportion of raw material piles varies greatly. In order to mix the ingredients uniformly, the order of the ingredients is to add coke and silica before the scrap. Using this batching method, the charge can be more evenly mixed after falling from the material tube. Whether the charge mix is uniform has a great influence on smelting. In order to mix the ingredients uniformly, only one batch of materials can be measured at a time, and each hopper can store more than two batches of materials.
