Description

A kind of metallurgical furnace furnace wall building machine

The utility model relates to the repair apparatus of a kind of metallurgical furnace furnace wall, is specially a kind of metallurgical furnace furnace wall building machine.

At present the refractory lining layer of the furnace wall of used blast furnace, steelmaking converter is to use refractory brick to build by laying bricks or stones on metallurgy industry, its brickwork joint position uses refractory clay to fill, because refractory brick body and refractory clay body exist the difference on the performances such as comparatively greatly different density, intensity, at identical temperature, pressure, corrode, wash away under the condition, the damage of refractory lining layer, at first from the fire clay bed of material at brickwork joint position, and cause the early stage damage of whole refractory lining layer, and the service life of having reduced stove, limit the raising of output, strengthened consuming cost.

In order to solve the flimsy problem of refractory clay of refractory lining layer brickwork joint, whole brickwork wall technologies such as the loose refractory of employing cast are also arranged, its good integrity, quality is even, but also exists the density and the lower weak point of intensity of refractory lining layer.

In order to prolong the service life of stove, the technology reparation of all adopting the loose refractory spray repair at present weathers and the badly damaged wall lining and the thickening of integral lining are repaired.When using pneumatic conveying spray lining machine to carry out the spray repair operation, because when the wall of furnace lining is arrived in the spray repair simultaneously of high pressure draught and material, drop into furnace bottom with producing a large amount of resilience material, promptly caused the waste of refractory material, increased production cost, furnace bottom is increased, dwindled the burner hearth cavity volume, reduced melting output, also existed flying upward of fire-resistant dust everywhere simultaneously, and cause pollution environment and workplace.The spray repair that also has to the refractory lining layer, adopt material-mud to use gun to carry out the spray repair build to the material-mud pressurized delivered, because material-mud has certain fluidity, the solution material that additional proportion is bigger in the material (as water etc.) is made carrier, the weak point of bringing like this is: the one, and the bed of material of institute's spray repair is thin excessively, and the intensity of the bed of material is on the low side; The 2nd, it is higher that the evaporation of liquid substance causes the porosity in the bed of material in the bed of material, thus bigger influence the erosion performance and the abrasion resistance energy of high temperature resistance solution of spray repair layer, also just influenced service life of the refractory lining layer of spray repair.

The purpose of this utility model provides a kind of metallurgical furnace furnace wall building machine, this metallurgy furnace furnace wall building machine can carry out spray repair and build to the fire-resistant interior whole wall of mending layer in the columnar furnace wall of furnace, use loose refractory that furnace wall refractory lining layer is built, the furnace wall refractory lining layer of building can keep good integrity, quality is even, keep the suitable thickness of inner liner again and had higher density and intensity, the furnace wall refractory lining layer that makes it to build has higher quality, satisfied instructions for use, prolonged the service life of stove, simultaneously can guarantee that again not resilience of material falls, the cavity volume that has promptly guaranteed burner hearth is constant, reduced the consumption of refractory material again, reduced cost, and avoided loose refractory fly upward the pollution that causes the workplace everywhere.

To achieve these goals, the utility model is that the upper and lower side at the leading screw of two settings is connected with upper junction plate and lower connecting plate respectively, be equipped with fixed head in the middle of two leading screws, be equipped with screw conveying device between upper junction plate, lower connecting plate, the fixed head, the screw conveying device lower end is equipped with the real device of centrifugal projecting machine peace seamless, is equipped with the transmission mechanism that two leading screws are rotated on fixed head.

Effect and the characteristics that the utlity model has are:

1, can be to the projection spray repair and the build of the whole wall of the columnar furnace wall refractory lining layer of furnace, the wall lining layer of building can keep good integrity, quality is even, keep the suitable thickness of refractory lining layer again and had higher density and intensity, the furnace wall refractory lining layer that makes it to build has higher quality, specification requirement and instructions for use have been satisfied, prolonged service life, simultaneously can guarantee that again not resilience of material falls, the constancy of volume that has promptly kept burner hearth cavity, reduced the consumption of refractory material again, saved its expense, and avoided loose refractory fly upward the pollution that causes environment and workplace everywhere.

2, this furnace furnace wall building machine also is applicable to the projection spray repair and the build of the columnar refractory lining of various elevated temperature vessels such as ladle, hot-metal bottle applicable to the projection spray repair and the build of the columnar furnace wall refractory lining of smelting furnaces such as blast furnace, steelmaking converter.

3, this furnace furnace wall building machine can use various types of loose refractorys.

4, it is fast that this furnace furnace wall building machine has speed of application, the efficient height, and characteristics such as the duration is short, and action required personnel are few can reduce operating expenses, shorten and build the duration, have improved the service efficiency of furnace.
