In 10mm, plating zinc on surface, plating are ironed and are difficult to.At present in industry during dual firing chamber's design, tackle for the corrosion of above-mentioned housing is main
Measure has three kinds：A kind of increasing hull plate corrosion allowance that passes through extends heating furnace service life；Second is to use acid resistance
Antirusting paint brushing shell inner surface；The third is that thinning refractory insulating layer thickness is solidifying to improve casing surface temperature minimizing acid dew
Knot amount.From the point of view of dual firing chamber's service condition of project is had been carried out with part, the shortcoming of above-mentioned several measures all presence.First, increase shell
There is following substantially drawback in body steel plate corrosion surplus：1st, rolled steel dosage is made to increase, cost increases, processing, installation difficulty increase；2、
Corrosion can cause refractory material grasp to come off with housing steel structure pad, large area peeling such as and can cause production accident.2nd,
There is following drawback in acid resistance anticorrosive paint brushing shell inner surface：1st, construction requirement height is it is difficult to accomplish to coat completely；2nd, coating
In addition to heat resistance is generally poor, its coat thermal coefficient of expansion is larger with the difference of refractory material, steel, in operating mode lower casing body
Dope layer can form thin segmentation crack, and corrosion reaction also can produce from crackle and complete corrosion process.3rd, improve casing surface temperature
There is following drawback：1st, equipment utilization efficiency of heat energy reduces, and increases Fuel Consumption；2nd, case temperature be generally greater than 150 DEG C with
Upper ability is effective to anticorrosion, and temperature is too high to have adverse effect to pipeline and control device, there is production safety hidden danger, simultaneously
The deterioration of workshop temperature environment can be caused.It is therefore desirable to proposing to improve.
