Abstract
The invention discloses an intermediate frequency smelting furnace building technology. The intermediate frequency smelting furnace building technology includes the following steps that 1 asbestos cloth is tailored in advance according to the size of an electric furnace, and a quartz sand mixture is prepared according to the size of an intermediate frequency furnace; 2 the asbestos cloth tailored in advance is arranged on a coil from top to bottom, wherein the coil is arranged in a cavity of a furnace body to be built; 3 daubing is conducted; 4 furnace baking and sintering are conducted. The intermediate frequency smelting furnace building technology is reasonable in process, simple to operate and low in production cost. After quartz sand and appropriate water are stirred and mixed, the adhesion is high, charging and daubing are convenient and simple, a furnace lining is high in compacting degree, and the service life of the furnace is prolonged. Furnace building is conducted by using the technology, the furnace building cost each time is 15000 RMB, the service life of a furnace built each time is about 430 years, the furnace building cost consumed by fusion per ton iron liquid on average is 11.63 RMB, the furnace building labor cost, the furnace building shut-down cost and the like are not included, and therefore the furnace building technology saves the furnace building cost and lowers the overall casting cost.
Description
Technical field
The present invention relates to a kind of intermediate frequency smelting furnace furnace building process.
Background technology
Former intermediate frequency furnace lining is built, adopt quartz sand dry mixing process to carry out, the degree of packing of furnace lining is poor, stove is shorter service life, and the expense that each brickwork needs is about 12000 yuan, and average brickwork once can melting 150 stoves left and right, 3 tons of iron liquid of every stove, the brickwork expense that average Smelting of iron per ton expends is 26.67 yuan, cost height very, and the difficult quality guarantee of brickwork.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides a kind of intermediate frequency smelting furnace furnace building process
The technical solution adopted for the present invention to solve the technical problems is:
A kind of intermediate frequency smelting furnace furnace building process, comprises the following steps:
Step 1, first cut asbestos cloth by electric furnace size, and prepare quartz sand compound according to the size of intermediate frequency furnace, quartz sand compound adopts the puddle mixer stirring that adds water, and stirring extent is agglomerating as standard to pinch;
Step 2: the asbestos cloth cutting is in advance distributed on the coil for the treatment of in brickwork build chamber from top to bottom, and leveling, the about 50mm of lap width, then, stainless steel warning network, furnace bottom alarm and second layer asbestos cloth being installed, and the necessary open loop of warning network, must not collide with furnace bottom alarm;
Step 3: daubing: divide respectively and three times quartz sand compound is inserted to furnace bottom and pave and tie by butt hammer, form the quartz sand mixing bed of material of three layers;
Step 4, baker and sintering: after wet method brickwork completes, only toast with firewood, add several times in burner hearth, make it completing combustion consecutive numbers hour to furnace lining is toasted.
In described step 4, to burner hearth baking three hours.
The invention has the beneficial effects as follows: a kind of intermediate frequency smelting furnace furnace building process, comprises the steps: 1, first cuts asbestos cloth by electric furnace size, and prepare quartz sand compound according to the size of intermediate frequency furnace; 2, the asbestos cloth cutting is in advance distributed in from top to bottom on the coil for the treatment of in brickwork build chamber; 3, daubing; 4, baker and sintering; Flow process of the present invention is reasonable, simple to operate, and production cost is low; Quartz sand is after suitable quantity of water is uniformly mixed, adhesion is stronger, feed in raw material, tie a knot and be convenient and simple, the furnace lining degree of packing is high, stove improves service life, adopt technique brickwork of the present invention, each brickwork expense is 15000 yuan, each brickwork service life is 430 stoves left and right, the brickwork expense that average melting per ton expends is 11.63, stops work and expends etc., therefore adopt furnace building process of the present invention but also do not comprise reduced brickwork labour cost, brickwork, save the cost of brickwork, and reduced cast-in-block cost.
Detailed description of the invention
A kind of intermediate frequency smelting furnace furnace building process, comprises the following steps:
Step 1, first cut asbestos cloth by electric furnace size, and prepare quartz sand compound according to the size of intermediate frequency furnace, quartz sand compound adopts the puddle mixer stirring that adds water, and stirring extent is agglomerating as standard to pinch;
Step 2: the asbestos cloth cutting is in advance distributed on the coil for the treatment of in brickwork build chamber from top to bottom, and leveling, the about 50mm of lap width, then, stainless steel warning network, furnace bottom alarm and second layer asbestos cloth being installed, and the necessary open loop of warning network, must not collide with furnace bottom alarm;
Step 3: daubing: divide respectively and three times quartz sand compound is inserted to furnace bottom and pave and tie by butt hammer, form the quartz sand mixing bed of material of three layers;
Step 4, baker and sintering: after wet method brickwork completes, only toast with firewood, add several times in burner hearth, make it continuous three hours of completing combustion to furnace lining is toasted.
Flow process of the present invention is reasonable, simple to operate, and production cost is low; Quartz sand is after suitable quantity of water is uniformly mixed, adhesion is stronger, feed in raw material, tie a knot and be convenient and simple, the furnace lining degree of packing is high, stove improves service life, adopt technique brickwork of the present invention, each brickwork expense is 15000 yuan, each brickwork service life is 430 stoves left and right, and the brickwork expense that average melting per ton expends is 11.63, stops work and expends etc. but also do not comprise reduced brickwork labour cost, brickwork, therefore adopt furnace building process of the present invention, save the cost of brickwork, and reduced cast-in-block cost, improved the efficiency of casting.
Above better enforcement of the present invention is illustrated; certainly; the present invention can also adopt form different from the embodiment described above; the conversion being equal to that those of ordinary skill in the art do under the prerequisite without prejudice to spirit of the present invention or accordingly change, all should belong in protection scope of the present invention.
