Ferrosilicon powder has many uses, and its application in some places is something that some people can't think of. So if you want to know more about ferrosilicon powder, please take a look at the following introduction.(1) Silica dust as refractory material
Refractory materials made of silica dust, such as insulation bricks, have a high melting point and good thermal stability. Silica has good thermal insulation properties, and the main component of many insulation materials is silica. These materials have low density and many micropores. In the interlaced pores, air is easily adsorbed and remains in a relatively static state. Therefore, it constitutes a good insulator. At present, refractory factories and some iron and steel colleges are conducting experiments in this area.(2) Using silicon dust to press ball back to furnace
Silica fume is ultra-fine particle dust. Therefore, when pressed into pellets, the reaction area is relatively large: during reduction, the heat required is smaller than that of silica; and at high temperatures. It has anti-breaking performance, helps to ventilate the furnace, promotes the reaction in the furnace, and plays a certain role in stabilizing the furnace condition.(3) Used as agricultural fertilizer
Silica and hydrogen hydroxide or carbon mixed with potassium can be poured into potassium silicate. Potassium silicate is a slow-acting fertilizer that is not easy to evaporate and lose. It can deeply protect the soil and promote the growth of crop roots. It can make crops grow firm and upright, resist lodging, and can inhibit pests and diseases.(4) Used as a filler for rubber
Due to the fine particles of silicon dust, it can play a good bonding role and can fill the gaps of rubber materials. The characteristic of rubber containing silica fume filler is its high relative elongation. Pit tearing strength and aging resistance, can play anti-wear, anti-permeability, and can also be used as a moisturizing material.
Therefore, ferrosilicon powder can not only be used as a refractory material, but also has applications in agriculture, and creates better growth conditions for crops. Ferrosilicon powder also contributes to rubber.
