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...

Abstract

The invention provides a fluidizaton roasting furnace ball arch furnace top. A heavy castable layer working lining adopts a high intensity low cement castable refractory or a steel fiber reinforced castable refractory. The inside of the layer is provided with a plurality of binaural stainless steel clips widthways to connect the castable material casting by different rings and blocks into a whole. The lateral wall of a camber angle ring beam is provided with a light clay brick and a connecting rib, the outside lateral wall is provided with a lateral wall reinforcing channel steel, the inner layer is provided with a plurality groups of stainless steel clips which connect the light clay brick, the heavy castable refractory layer working lining and the lateral wall reinforcing channel steel into a whole. The forming method is as follows: (1) the center of gravity and the symmetric center of the furnace top are arranged in one line; (2) the furnace top is divided into a plurality of small blocks, the bottom arc length is less than or equal to 1.2 meters; (3) the mould is supported according to the divided small blocks; (4) a heat insulating material is arranged and the thickness of the heat insulating material is set; (5) the integral casting is performed. The fluidizaton roasting furnace ball arch furnace top has the advantages of good leak tightness, high intensity, long service life, short construction cycle and low cost, does not have any gap and does not fall off.

Description

technical field [0001] The invention relates to fluidized roasting furnace technology, in particular to a spherical arch roof of a fluidized roasting furnace and a forming method thereof. Background technique [0002] At present, the large-scale fluidized roasting furnaces used in my country (including technologies introduced by other countries in the world and my country) all adopt arched structures. The diameter of the arch angle can reach 10M-30M, and the working temperature in the furnace is generally 650°C-1200°C. The working lining of the furnace top is traditionally built with various wedge-shaped refractory bricks, and the upper part of the working lining is built with insulating bricks. A considerable cavity is left on the upper part of the insulation brick, and the upper part of the cavity covers the furnace roof steel shell and is fixed together with the wall furnace steel shell to prevent the deformation of the side wall steel shell and prevent rain and snow from...
