The spacing that adjacent screen puts 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, hook can be utilized to be fixed on inside exhaust fume collecting hood by the refractory brick of body of wall section top layer, 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 that is fixedly connected with exhaust fume collecting hood steel construction.
For making hook stress balance, the quantity of described peg preferably 2, 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, comprise the following steps:
(1), with fire clay, refractory brick is successively upwards built by laying bricks or stones, the boss of refractory brick and groove are as the primary and secondary occlusion structure of levels brick when building by laying bricks or stones, when building the refractory brick of body of wall section top layer by laying bricks or stones, first need install hook, concrete grammar is inserted in the hook hole of refractory brick by the peg of hook, then hang on hanger plate by the coupler body of the hook other end;
(2), at refractory brick surface paving one piece of fire-resistant soft board 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 baffles is placed on the top that baffle plate puts plate;
(3), continue above baffles, to build refractory brick by laying bricks or stones, until completed by whole metallurgical furnace exhaust fume collecting hood building wall according to the method for above-mentioned steps 1, step 2.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect:
1, because employing baffle plate puts plate and exhaust fume collecting hood body of wall is separated into multiple independently body of wall section by baffles, the danger causing whole body of wall to come off by the metallurgical gas temperature difference is avoided.
2, owing to arranging hook structure in exhaust fume collecting hood body of wall, the adhesive force of exhaust fume collecting hood steel construction and refractory brick is added.
