Description
Technical field
The utility model relates to a kind of fire door lining brick of coke oven, the fire door lining brick of coke oven of the diffusing heat insulation material of shape of especially a kind of rest shape of a hoof hollow perfusion.
Technical background
At present, coke oven door uses high alumina trichroite lining brick mostly, and its brick type is thinner, and horizontal brickwork joint is many, tar trickling was not smooth when coke oven opened the door, and tar easy to hang, firmly adhere are removed difficulty on lining brick, both influence workman's operating environment, damaged the fire door lining brick again easily, shortened work-ing life.This fire door lining brick of coke oven weight is big, and effect of heat insulation is poor.
Summary of the invention
In view of the problems referred to above that exist, the purpose of this utility model is the fire door lining brick of coke oven that the diffusing heat insulation material of shape of cast in its high alumina trichroite brick that forms hollow bore, the hollow bore is increased and can be made to a kind of outside of development rest, peripheral employing brick type; Make under the situation of proof strength that gross weight alleviates, few, the not easy to hang tar of heat insulation good, horizontal brickwork joint, good operational environment, long service life.
In order to realize the purpose of this utility model, the technical measures of taking are fire door lining brick of coke oven of the diffusing heat insulation material of shape of a kind of rest shape of a hoof hollow perfusion of design, it is characterized in that what it was made up of shape of a hoof brick body 1, glaze layer 2, the diffusing heat insulation material elongated hole of shape post pour mass 3 and brick ditch 4; Being provided with stove in the middle of the shape of a hoof brick body 1 inboard is that arc, door side are the elongated hole of opening, edge, distance that curved edge is located at shape of a hoof brick body 1 are not less than the 100mm place, the diffusing heat insulation material of shape of the heat insulation material elongated hole of shape post pour mass 3 usefulness of loosing is poured into a mould in elongated hole and is formed, brick ditch 4 is located at the elongated hole open side on shape of a hoof brick body 1 both sides, and glaze layer 2 hangs over the outside surface of shape of a hoof brick body 1.
Described shape of a hoof brick body 1 is by the brick one-tenth of high alumina trichroite that highly is 1500-1800mm.
Described glaze layer 2 thickness are 1-2mm, and use temperature is greater than 1100 ℃.
Its thermal conductivity of the heat insulation material of described diffusing shape is not higher than 0.04-0.06 kilocalorie/rice. the time. ℃, volume density is 0.1-0.3g/cm
3, working temperature is that 1000 ℃, granularity are 2-3mm.
The fire door lining brick of coke oven of the diffusing heat insulation material of shape of the utility model rest shape of a hoof hollow perfusion is increased owing to outside rest, peripheral employing brick type and can be made the middle high alumina trichroite brick of microscler hole, the diffusing heat insulation material of shape of the interior cast of middle microscler hole of becoming; So its gross weight is light, good heat-insulation effect, few, the not easy to hang tar of horizontal brickwork joint, good operational environment, long service life.
Description of drawings
Fig. 1 is the one-piece construction synoptic diagram of the fire door lining brick of coke oven of the diffusing heat insulation material of shape of rest shape of a hoof hollow perfusion.
Fig. 2 is the A-A cross section cutaway view Amplified image among Fig. 1.
As illustrated in fig. 1 and 2, the coke oven door lining of the diffusing heat insulation material of shape of rest shape of a hoof hollow perfusion Brick is by shape of a hoof brick body 1, glaze layer 2, the diffusing heat insulation material elongated hole of shape post pour mass 3 and brick ditch 4 Form. Shape of a hoof brick body 1 is by the brick one-tenth of high alumina cordierite that highly is 1500-1800mm , it is inboard for arc, door side are the elongated hole of opening to be provided with stove in the middle of it, and curved edge is established Edge, distance at shape of a hoof brick body 1 are not less than the 100mm place. So both guaranteed lining brick Intensity has alleviated again the gross weight of lining brick. The brick type is increased, and has greatly reduced horizontal brickwork joint, has Be beneficial to the trickling of tar, it is few to hang tar, is convenient to remove, and not fragile lining brick has prolonged use Life-span. The thickness of glaze layer 2 is 1-2mm, and serviceability temperature makes the surface of lining brick greater than 1100 ℃ Smooth and hardness is high, tar not easy to hang has improved operating environment, has prolonged the use longevity of lining brick Life. The heat insulation material elongated hole of the shape post pour mass 3 that looses is that thermal conductivity factor is not higher than the 0.04-0.06 kilocalorie / rice. the time. ℃, bulk density 0.1-0.3g/cm3, operating temperature is 1000 ℃, granularity 2-3mm The heat insulation material of diffusing shape be poured into and form in the middle elongated hole of shape of a hoof brick body 1, make lining brick Gross weight approximately reduces 1/3rd, and its cost is low, can offset the rest expense, because fire door is light, Make the also corresponding reduction of mechanically actuated expense; Also improved simultaneously effect of heat insulation.
Embodiment
Introduce technology contents of the present utility model in detail below in conjunction with drawings and Examples: shown in attached Fig. 1 and 2, at first make the high high alumina trichroite brick (Al of brick for the different shape of 1500-1800mm and size
