The spacing that adjacent screen is put plate is preferably the thickness of 5～8 blocks of refractory brick.
The refractory brick of described body of wall section top layer is also provided with hook hole, can utilize hook that the refractory brick of body of wall section top layer is fixed on to exhaust fume collecting hood inner side, hook one end is provided with peg, the other end is provided with coupler body, described peg is enclosed within the hook hole of refractory brick, and coupler body hangs on the hanger plate being fixedly connected with exhaust fume collecting hood steel construction.
For making to link up with stress balance, preferably 2 of the quantity of described peg, symmetry is located at the both sides of hook.
The building method of metallurgical furnace exhaust fume collecting hood body of wall, is characterized in that, comprises the following steps:
(1), with fire clay, refractory brick is successively upwards built by laying bricks or stones, the primary and secondary occlusion structure of the boss of refractory brick and groove levels brick when building by laying bricks or stones, in the time building the refractory brick of body of wall section top layer by laying bricks or stones, need first install hook, concrete grammar is that the peg of hook is inserted in the hook hole of refractory brick, then the coupler body of the hook other end is hung on hanger plate;
(2), at a fire-resistant soft board of refractory brick surface paving of each body of wall section top layer, make that fire-resistant soft board surface will to put plate surface concordant with baffle plate, then the top that baffles is placed on to baffle plate and puts plate;
(3), continue above baffles, to build refractory brick by laying bricks or stones according to the method for above-mentioned steps 1, step 2, until whole metallurgical furnace exhaust fume collecting hood building wall is completed.
Owing to having adopted technique scheme, the present invention compared with prior art has following beneficial effect:
1, because employing baffle plate is put plate and exhaust fume collecting hood body of wall is separated into multiple independently body of wall sections by baffles, avoided the danger that causes whole body of wall to come off by the metallurgical gas temperature difference.
2,, owing to hook structure being set in exhaust fume collecting hood body of wall, increased the adhesive force of exhaust fume collecting hood steel construction and refractory brick.
