Abstract
The utility model relates to a blast furnace main iron runner of circulated use toasts apron, including the apron casing, its characterized in that apron casing lower part be equipped with refractory fiber felt and fire-resistant heat preservation pouring material in proper order apron casing upper portion intermediate position open and to have exhaust hole and fork truck hoist and mount draw-in groove. Compared with the prior art, utility model's advantage is: the utility model discloses owing to set up refractory fiber felt and fire-resistant heat preservation pouring material in the apron casing, improved blast furnace slag iron runner cover's thermal-insulated effect effectively, prolonged its life. Meanwhile, due to the arrangement of the forklift hoisting clamping groove, the forklift is convenient to transport and hoist, and the labor intensity of workers is reduced.
Description
Technical Field
The utility model belongs to the technical field of ironmaking equipment, specifically be a cover plate is toasted to circulated use's blast furnace owner iron runner.
Background
Blast furnaces are important places for iron and steel smelting. At present, the blast furnaces of most metallurgical enterprises at home and abroad bake the main iron runner of the large blast furnace by adopting coal gas, and a galvanized iron plate with the thickness of 1mm is generally used to cover the main iron runner, because the baking time is long, the baking temperature is high, the galvanized iron plate is easy to deform and oxidize and thin at high temperature to cause the reduction of the service life, the galvanized iron plate deforms and collapses in the baking process, the heat loss is large during the baking of the main runner, the energy consumption is large, the baking efficiency and the baking quality are influenced, the tapping time of the blast furnace can be delayed due to the above influences, and physical water and crystal water in the castable can not be completely separated due to the uneven baking temperature, so that the castable can easily cause the phenomena of cracks and material collapse at high temperature during the tapping of the blast furnace. Directly leads to the normal tapping of the main iron runner of the blast furnace, influences the normal operation of the blast furnace and causes certain economic loss for iron works.
The two existing schemes aiming at the blast furnace main ditch cover plate comprise a high-heat-efficiency roaster for a blast furnace slag iron ditch refractory cover plate and a second scheme which comprises the following steps: a galvanized iron sheet cover with a thickness of 1 mm. The process from baking to tapping of the blast furnace main channel needs to be completed within a specified time. The two cover plates have the following defects that 1, the step of the roaster is various, the site situation is complex when the blast furnace is constructed, and the roaster works in a live line, so that the site safety accident is easy to cause. 2. The galvanized iron plate with the thickness of 1mm is covered on the main iron runner, and due to the fact that the baking time is long, the baking temperature is high, the galvanized iron plate deforms after high temperature, the galvanized iron plate is oxidized and thinned at high temperature, the service life is short, the galvanized iron plate deforms and collapses in the baking process, heat loss is large during baking of the main runner, energy consumption is high, baking efficiency and baking quality are affected, and normal tapping is affected.
Disclosure of Invention
The utility model aims at providing a blast furnace main iron runner baking cover plate which can be recycled.
The purpose of the utility model is realized like this.
The utility model discloses a blast furnace main iron runner of circulated use toasts apron, including the apron casing, its characterized in that apron casing lower part be equipped with refractory fiber felt and fire-resistant heat preservation pouring material in proper order apron casing upper portion intermediate position open and to have exhaust hole and fork truck hoist and mount draw-in groove.
Preferably, the cover plate shell is of a groove structure, anchoring hooks are welded in the cover plate shell, and the refractory fiber felt and the refractory heat-preservation pouring material are embedded into the grooves.
Preferably, the number of the forklift hoisting clamping grooves is two, the two forklift hoisting clamping grooves are respectively arranged on two sides of the exhaust hole, and a cover plate with a hinge is arranged on the upper portion of the exhaust hole.
Preferably, the thickness of the refractory fiber felt is 5mm-7 mm.
Compared with the prior art, utility model's advantage is:
the utility model discloses owing to set up refractory fiber felt and fire-resistant heat preservation pouring material in the apron casing, improved blast furnace slag iron runner cover's thermal-insulated effect effectively, prolonged its life. Meanwhile, due to the arrangement of the forklift hoisting clamping groove, the forklift is convenient to transport and hoist, and the labor intensity of workers is reduced.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
As shown in figure 1, the utility model discloses a blast furnace owner iron runner of circulated use toasts apron, including apron casing 1, its characterized in that apron casing 1 lower part be equipped with refractory fiber felt 2 and refractory insulation castables 3 in proper order apron casing upper portion intermediate position open and to have exhaust hole 5 and fork truck hoist and mount draw-in groove 4 exhaust hole upper portion set up and to have the apron of folding paper.
The cover plate shell 1 of the utility model is of a groove structure, the anchoring hooks 7 are welded in the cover plate shell 1, the refractory fiber felt 2 and the refractory heat-preservation pouring material 3 are embedded in the groove,
the thickness of the refractory fiber felt 2 is 5mm-7 mm, and the arrangement of the refractory fiber felt 2 effectively improves the heat insulation effect of the blast furnace slag iron runner cover plate. The forklift lifting clamping grooves 4 are respectively arranged on two sides of the exhaust hole 5, and a cover plate with a hinge is arranged on the upper portion of the exhaust hole 5. The forklift is convenient to fork and lift, and the labor intensity of workers is reduced.
The utility model discloses a toast and cover exhaust hole 5 that has the ability switch, 5 upper portions in exhaust hole set up and have apron 6 of folding paper, need open the exhaust hole when the temperature reaches more than 200 ℃, need not to open the exhaust hole when being less than temperature 200 ℃, make it guarantee to toast the temperature in the ditch. The main ditch is baked by gas with small fire at the initial baking stage, the water content in the main ditch is high, water vapor can be discharged through the exhaust holes, the water vapor in the main ditch is gradually reduced along with the rise of the temperature in the main ditch, the exhaust holes are closed at the later baking stage, the temperature in the main ditch is baked by big fire, and the main ditch can be baked for ten days to meet the tapping requirement.
