Embodiment 1
[0045] Taking the spherical arch roof of a 45m2 fluidized roaster as an example, the roof structure: the overall structure of the roof is set to three layers, the outer layer of the roof is set as a steel shell, the middle is an insulation layer, and the inner layer is an amorphous refractory Light heat-preserving castables, in the integral casting furnace lining, a plurality of stainless steel anchors are provided as the skeleton, and the heavy wear-resistant castable working lining 4 is connected with the arch angle ring beam 5 and the side wall reinforced channel steel to form a whole. 1. Working conditions: ①. Working temperature: 800-1000℃. ②, working medium: SO 2 , SO 3 , mine dust, A S, F and so on. 2. Roof structure: ①, spherical vault; ②, spherical arch radius: SR = 9000mm; ③, arch height: H = 1206mm; ④, furnace roof refractory layer thickness: f = 300mm. The forming method adopts the following steps: 1. Work preparation: (1), the mold conforms to the design requi...
