Anode roasting oven cross-wall structure

Abstract

The invention discloses a cross-wall structure, and particularly relates to an opened-type anode roasting oven cross-wall structure in the production field of anode for aluminum, which is characterized in that: each odd level of a cross wall consists of an odd level composite fire-resisting component and two side solid components, a linear expansion gap is arranged between the odd level composite fire-resisting component and the solid components, and the odd level composite fire-resisting component is formed by compounding an odd high-temperature-resisting strength frame box and low-thermal-capacity fire-resisting filler; each even level of the cross wall is formed by continuously building even level composite fire-resisting components, a curve-type expansion gap is arranged between every two adjacent even level composite fire-resisting components, each even level composite fire-resisting component is formed by compounding even high-temperature-resistant strength frame box and low-thermal-capacity fire-resisting filler, and solid components at two sides of the even high-temperature-resistant strength frame box are integrated with the even high-temperature strength frame box into a whole. Due to the adoption of the structure, the general weight of the cross wall can be reduced by about 40 percent, so the heat loss of an anode roasting oven can be greatly reduced. The anode roasting oven cross-wall structure has a simple structure, is economical and practical, and is easy to implement.

Description

Technical field [0001] The invention relates to a horizontal wall structure, in particular to an open anode baking furnace horizontal wall structure in the field of anode production for aluminum. Background technique [0002] In the aluminum anode baking production process, the heating temperature of the anode product exceeds 1050°C, and the horizontal wall as a component of the material box must be heated to above 1000°C. When the heating process is completed, the horizontal wall at such a high temperature will dissipate all the accumulated heat to the atmosphere, and it has become the main component of the heat loss of the anode baking furnace. [0003] The current anode baking furnaces for aluminum use solid heavy refractory materials in order to make the horizontal wall have structural strength enough to resist the thermal stress transmitted by the fire channel wall and ensure that the bin can work normally at high temperatures. Horizontal wall, among the heavy refractory mate...
