A exempt from prefabricated brick of sintering that is used for positive pole carbon element roaster flame path wall for aluminium

The utility model discloses an exempt from prefabricated brick of sintering that is used for positive pole carbon element roaster flame path wall for aluminium, include and personally experience sth. Part of the body by indefinite form refractory material moulding by casting's the prefabricated brick of sintering of exempting from, staggered arrangement sets up a plurality of rectangular channels that are used for the installation to roll over the aerofoil on exempting from the brick face of the prefabricated brick of the sintering body, has seted up the rectangular bleeder vent of a plurality of transversal joints along its longitudinal separation on the brick face of exempting from the prefabricated brick body of sintering, exempt from the left surface and/or the right flank of the prefabricated brick of the sintering body and go up the side and/or the downside is offered the cross sectional shape respectively and is convex lock groove. The utility model discloses the advantage lies in carrying out the equipment of flame path wall through seting up in the lock groove of the arc of exempting from the prefabricated brick side face of sintering, therefore the brick body has been overcome current machine -processed baked brick and is received the not enough of dimensional limit in the preparation for the on -the -spot hoist and mount of accessible are assembled when building the construction of flame path wall by laying bricks or stones, through the adjacent prefabricated brick side face of sintering of exempting from the lock groove is connected as an organic wholely, and the engineering time is practiced thrift more than 90%.
