Notes On Raw Materials For Smelting Ferrosilicon 75

1. The weighing of raw materials for smelting ferrosilicon 75 should be accurate. All kinds of raw materials must be weighed according to the specified quantity with small errors. If the weighing is not accurate, the furnace condition is not easy to grasp, and may even produce waste products. Therefore, the dosage work should be careful, and the accuracy of the weighing tool should be checked frequently. Problems found should be adjusted or repaired in time.

2, smelting ferrosilicon 75 raw materials should be by the prescribed batching order, to make the batching mix evenly. The specific gravity of the coke heap is about 0.5~0.6. the specific gravity of the silica heap is about 1.5~1.6, and the specific gravity of the scrap heap is 1.8~2.2. the proportion of raw material heap varies a lot. To mix the ingredients evenly, the batching sequence is to add coke and silica before scrap. With this batching method, the furnace charge can be more evenly mixed after falling from the charge pipe. The homogeneity of the charge mix has a great influence on the smelting. To make the dosage mix evenly, only one batch of material can be measured at a time, and more than two batches of material can be stored in each hopper.
