对于加热炉炉衬来说,纤维喷涂技术采用优质纤维原棉,高性能纤维系列结合剂为原料,在一次性整体喷涂过程中形成网络结构,与其他施工方法相比,具有以下优点:
For the heating furnace lining, fiber spraying technology using
high quality cotton fiber, binder series high performance fiber as raw
material, the formation of a network structure in the whole process of
one-time spraying, compared with other construction methods, has the
following advantages:
(1)一次性喷涂所获得的衬层无接缝,有效地避免了纤维制品在高温下的定向收缩,消除了窜气、露点腐蚀等对炉壳、锚固钉的危害,强化了密封、保温耐火性能,提高了炉窑的热效率。
(1) the spraying lining joints, effectively avoid the directional
shrinkage fiber products under high temperature, eliminating gas
channeling, dew point corrosion of furnace shell, harm anchor nail,
strengthening the seal and refractory insulation performance, improves
heat efficiency of furnace.
(2) 纤维喷涂技术可以降低复杂形面,如球面、拐角、炉门及排烟管结合处等部位整体锚固的施工难度,进步了异形结合处的密封性能。衬层坚固、均匀而平整,具有较强的抗腐蚀能力。喷涂施工方便、灵活,锚固钉用量少,且全部埋在纤维炉衬里,有效防止钉头烧损,避免热短路。
(2) fiber spraying technology can reduce the complexity of the
construction of complex surface, such as sphere, corner, furnace door
and smoke exhaust pipe, and improve the sealing performance of the
special-shaped joint. The liner is firm, uniform and smooth, and has
strong corrosion resistance. The spraying construction is convenient and
flexible, and the anchor pin is used less, and all are buried in the
lining of the fiber furnace, so as to effectively prevent the pin head
from burning and avoid the thermal short circuit.
(3)喷涂纤维衬层具有比平毡、毯较低的导热系数,比立展折叠块有较好的热强度,锚固件埋于喷涂层内不直接传递热量,节能达15%~30%。
(3) spraying fiber layer has a lower thermal conductivity than the
flat mat, carpet, folded pieces of hot strength than show good, anchor
buried in the spraying layer does not directly transfer heat, such as
15%~30%.
(4)喷涂施工经济实用,可以根据产业炉工况,采用多种纤维分层复合喷涂,有利于实现复合材料传热机理的温度梯度分布,降低衬层材料的综合造价。
(4) spraying construction is economical and practical. According to
the industrial furnace working condition, a variety of fiber layered
composite spraying is adopted, which is beneficial to realize the
temperature gradient distribution of the heat transfer mechanism of
composite materials and reduce the comprehensive cost of lining
materials.
(5) the spraying speed of refractory fiber is 4.5 times higher than
that of conventional construction method, especially for rush repair
project. The coating structure belongs to the flexible material, the
spraying construction can be put into use after completion, reducing the
drying time of nearly |
