Embodiment
As shown in Fig. 4 ~ Fig. 5, a kind of fire door lining brick of coke oven, comprise: firedoor frame shell 1 and refractory precast block, described refractory precast block comprises work lining 2 and heat insulating lining 4, heat insulating lining 4 and work lining 2 are fixed on inside firedoor frame shell 1, heat insulating lining 4 embeds in work lining 2, and one side is close to inside firedoor frame shell 1, and its lap has work lining 2 to wrap up.Separated by work lining 2 in the middle of described heat insulating lining 4 and support middle point of suppon or the supporting beam that also can be provided with work lining 2 of i.e. heat insulating lining.The utility model heat insulating lining 4 is made up of aluminum silicate fiber material, and thermal conductivity is very low, only has 1 ~ 2% of work lining thermal conductivity, and work lining thermal conductivity is less than 1, has good thermal and insulating performance.
The main raw of work lining 2 is refractory materialss, has and can be subject to thermal shocking, chemical corrosion and Focal drug-block and destroyed performance for a long time, to tar and knot carbon avidity weak, adopt wind or besom cleaning to clean out.
Described heat insulating lining 4 and work lining 2 are fixed on inside firedoor frame shell 1 by least two bolts 3.Described bolt 3 is symmetrical arranged at point left and right two row on lining 2 that work, and often row comprise 1-3 row bolt.Each work lining needs to install with 2-6 bolt, and described bolt 3 length stretched in work lining 2 is less than the half of work lining 2 thickness.Described work lining 2 is preset with bolt hole, and bolt hole size matches with bolt 3.Described refractory precast block is 4-6 block, forms a line up and down and snugly fits into inside firedoor frame shell 1.Described heat insulating lining 4 and work lining 2 make one.Bolt can make one with refractory precast block, also can preset bolt hole on refractory precast block, when mounted on-the-spot loading.
Firedoor frame shell 1 carries out segmental structure design according to the height of fire door, a usual large-scale fire door can be divided into 4-6 section as required, the height of each section is 0.5-1.5m, and arranges the multiple bolts hole for installing refractory precast block, for installing 4-6 block refractory precast block at each section.
Refractory precast block in the utility model is 4-6 block, form a line up and down and snugly fit into inside firedoor frame shell 1, the seam of whole like this door lining is considerably less, the cross-sectional structure of this refractory precast block is the trapezoidal of outer narrow inner width at its installation side, to make after installation at refractory precast block, forms two leg-of-mutton spaces, left and right between firedoor frame shell 1 and carbonizing chamber furnace wall.Just can become gas flue so in use, coal gas be introduced carbonizing chamber top.If have tar to adhere in passage or knot carbon, just can dispose timely and conveniently during oven door opening.
This composite structure of the utility model fire door lining brick has good use properties and thermal and insulating performance.On the 6 meters of coke ovens in one, tafelberg, effect clearly, coking chamber end flue temperature can improve 40 DEG C, and shorten coking time 20 minutes, fire door skin temperature can reduce by more than 40 DEG C, ensure that fire door skin temperature is below 100 DEG C, ensure that use properties and the life-time dilatation of fire door steel structure well.If this seat 6 meter of 60 hole coke oven adopts the energy-conservation lining brick of the utility model fire door entirely, end flue temperature improves 40 DEG C, annual saving heating gas consumption, be equivalent to mark 613 tons, coal, fire door skin temperature reduces by 40 DEG C, the heat lost by radiation reduced in 1 year is equivalent to 207 tons of mark coals, and two add up to 1 year and save mark 820 tons, coal altogether.
