Smelting ferrosilicon, ingredient is the first step to pay attention to. The amount of ingredients has a direct impact on the quality of smelting, then, in the smelting of ferrosilicon, how should we ingredients? Next, I would like to share briefly with you.
When preparing ferrosilicon, it is necessary to pay attention to the following:
1, weighing accurately, all kinds of materials must be weighed according to the prescribed quantity, the error is small. If weighing is not allowed, the furnace condition is not easy to master, or even waste. Therefore, batching work to be careful, but also often check the accuracy of weighing tools, found problems should be adjusted or repaired in a timely manner.
2, we should make batching in accordance with the prescribed order so as to mix the burden evenly. The pile weight of coke is about 0.5 ~ 0.6, and the pile weight of silica is about 1.5 to 1.6, and the pile weight of steel chips is 1.8 to 2.2. The proportion of material piles varies greatly. In order to mix the burden evenly, the batching order is coke and silica, and then the steel chips. With this kind of ingredient method, the burden of the furnace can be mixed evenly after the material tube is lowered. Uniform mixing of furnace burden has great influence on smelting. In order to mix the burden evenly, only one batch of material is allowed at a time, and the material for each hopper is over two batches.
In addition, we need to remind you that the smaller the batch, the more conducive to mixing uniform, otherwise difficult to uniform. Therefore, small batch should be used as far as possible.
