烧结机生产率取决于料层的透气性,而其中料层的气体动力学方面的阻力则取决于篦条状态。南方选矿公司烧结厂烧结台车的篦条是由公司的铸造车间及其他制造厂供应的。灰铸铁制造的篦条寿命低,因为在工作中篦条承受高温及废气中粉尘的磨损作用。对篦条的加热及冷却制度进行测量表明:其表面温度周期地从140℃变化到540℃,在这种工作制度下,铸铁篦条不仅由于热稳定性不够而破坏,而且加热超过400℃时,由于渗碳体
The productivity of the sintering machine depends on the permeability of the material layer, and the aerodynamic resistance of the material layer depends on the grate state. The grate bars of Sinter plant sinter trolleys at Southern Processing Corporation are supplied by the company’s foundry and other foundries. Grate bars made of gray cast iron have a low life expectancy because the grate bars are exposed to high temperatures and the wear of dust in the exhaust gas during operation. Measurement of the heating and cooling of the grate bar showed that the surface temperature of the grate bar was changed periodically from 140 ° C. to 540 ° C. Under this system of operation, the cast iron grate bar was not only destroyed due to insufficient thermal stability but also heated to over 400 ° C. , Due to cementite
