Thermal insulation material for ferrosilicon furnace

In the smelting of alloys, silicon iron releases a large amount of heat when silicon is oxidized into silicon dioxide, which is beneficial for increasing the temperature of molten steel. Considering energy conservation and consumption reduction, it is necessary to carry out insulation treatment for silicon iron furnaces and high-temperature anti-corrosion treatment for supporting equipment.

The temperature of the ferrosilicon furnace is over one thousand degrees Celsius, responsible for melting and mixing ferrosilicon raw materials, also known as an electric arc furnace or resistance electric furnace. The power consumption is very high, and if the insulation treatment is not done well, it will cause heat loss and increase energy consumption. The ferrosilicon furnace is equipped with a dust removal system and a smoke exhaust system, which endure varying degrees of frictional corrosion and high-temperature corrosion. This requires proper wear-resistant and high-temperature anti-corrosion treatment.

ZS-1Thermal insulation material for ferrosilicon furnaceheat-resistant2000At ℃, it can withstand high temperatures of over a thousand degrees Celsius in the furnace body. It can be coated inside the furnace body for insulation, and the coating thickness should be designed according to specific working conditions. The experimental data for this coating is1100Painting of high-temperature objects at ℃8mmThe thickness of the film.Thermal insulation material for ferrosilicon furnaceDue to the use of ceramic hollow microspheres and Zhisheng Weihua's specially designed high-temperature solution as the main components of the coating, it can withstand high temperatures of up to 2000 degrees and reduce heat conduction, thereby achieving insulation and heat preservation effects. Silicon iron solution has a strong thermal shock effect and has a strong ability to damage molds. It can be coated inside the moldZS-522High temperature resistant self-cleaning non adhesive coating, avoiding direct contact between the mold and silicon iron solution, protecting the mold from damage caused by high temperature thermal shock.

There are many types of dust removal equipment with different dust removal principles, which will not be explained in detail here. At the same time, it should be noted that this method is only applicable to dust collectors that require wear-resistant protection treatment. The high-speed smoke and dust directly enter the dust collector, which has a significant scouring effect on the equipment inlet. In addition, the high temperature causes wear and damage to the dust removal equipment.ZS-1031Wear resistant and anti-corrosion coatings with high temperature resistance600℃, able to withstand high temperature corrosion from smoke, wear-resistant and durable, extending service life.

The protection treatment of flue gas pipelines is relatively complex because the corrosion environment inside and outside the pipeline is different, and the selected coatings are also different. The inner wall of the pipeline needs to be paintedzs-1041Smoke anti-corrosion coating, the smoke composition of ferrosilicon furnace is not very complex, mainly high temperature and a small amount of smoke and dust. The use of smoke anti-corrosion coating for protection is more than enough. This coating is mainly used for the anti-corrosion of flue gas after desulfurization in thermal power plants, with wear resistance, impermeability, high adhesion, temperature change resistance, stress resistance, acid and alkali resistance, etc. Coating the outer wall of the pipelinezs-811High temperature anti-corrosion coating is sufficient, as it has the highest temperature resistance2300℃, mainly used for high-temperature oxidation damage of industrial high-temperature equipment, isolating the contact between substrate and oxide.
