6、 纳米远红外增热制膜技术

Nano far-infrared heating film technology

纳米远红外增热制膜技术是指利用纳米微粉形成的小颗粒通过高温反应胶结到耐火球的表面，使得耐火球表面形成一层具有吸收热能很大的膜层，纳米粉的颗粒直径和远红外线的波长相接近，能够更好地吸收物体辐射的热能，终达到热交换的目的，所以我们给这种新技术定义为纳米远红外增热制膜技术。

It is by using granulum from nano-powder,which is cemented to the surface of refractory ball through high-temperature reaction. And the surface of refractory ball will from a film with function of high heat absorption. The diameter of nano particle is close to the wavelength of far infrared ray, so it can better absorb heat of radiation and finally achieve the aim of heat exchange.

纳米远红外制膜技术，主要在改善耐火球的体积密度和降低气孔率上，在热交换的循环过程中，单位时间内的蓄热和放热的能力都得到了提高，热传导的热效率也相应提高。等于说燃烧时间内，耐火球吸收的热量和吸热的速度增加了，送风时期耐火球的放热量和放热速度也增加了，从而达到热交换效率的提高，相同时期内废气的温度降低了。单位时间内耐火球的蓄放热的量增加，能够使热风温度提高。高炉的冶炼强度提高了。

It is mainly used to improve the bulk density and porosity of refractory ball. In the heat exchange circulation process, the capacity of heat storage and heat release are improved in unit time. And the heat conductivity is also improved. As the capacity of heat storage and release are improved, the hot blast temperature is increased, which improves the smelting intensity for blast furnace.

制膜和不制膜对比试验:

Contrast Text:

项目 Item	体积密度 Bulk density	气孔率 Porosity	耐压强度 Crushing strength	荷重软化 Refractoriness under load	高温蠕变 High temperature creep	热震稳定 Thermal shock stability
	g/cm3	%	N/球ball	℃	%	次time
有涂膜 Coating film	2.63	20.4	27400	1537	-0.27	25
无涂膜 No film	2.54	22.3	14100	1503	-0.43	21

通过在日照钢铁厂、萍乡钢铁厂、山东石横钢铁厂等多家厂家的试用和验证：有制膜技术相对无制膜耐火球的热风炉，燃烧期吸热快，蓄热量增加；放热期内放热快，热风出口温度高约18-25℃；烟气出口温度约低10-15℃。从而达到提高风温，增强冶炼强度并且达到节能的目的.

With verification test in several steel plants, the hot blast stove with refractory ball of coating film can absorb heat quickly and increase the hest storage. Moreover it can raise the hot blast temperature and strengthen the smelting intensity, which accomplish the aim of energy conservation.
