Description
Technical Field
The utility model relates to a row's sediment device of steel rolling heating furnace belongs to metallurgical industry steel rolling heating furnace equipment technical field.
Background
In the production of hot rolled steel, a heating furnace is used as a heating furnace apparatus for a billet, and when the billet is heated in the heating furnace, a certain amount of slag such as iron scale is generated, and the slag adheres to the surface of the billet, gradually falls into the heating furnace during the transportation of the billet, is discharged from the furnace bottom to the outside of the furnace, is collected and reused, and an apparatus for discharging the slag from the furnace bottom to the outside of the furnace is called a furnace slag discharging apparatus.
At present, a slag discharging device of a heating furnace is generally formed by welding a steel plate, profile steel and the like, then paving a layer of refractory mortar on the inner side of the steel plate, and then welding and fixing the refractory mortar on the bottom of the heating furnace in a suspension manner. The heating furnace slag discharging device with the structure has the advantages of long manufacturing period, high cost, inconvenient installation and poor safety of suspension installation. In the use, the waste residue rubs the inner fireproof mud for a long time, and the steel plate can be burnt through after the fireproof mud is worn or falls off, so that the fire leakage phenomenon appears at the bottom of the heating furnace, the service life of the slag discharging device is influenced, and meanwhile, great potential safety hazards exist.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a row's sediment device of steel rolling heating furnace, simple structure, safe and reliable, long service life can not appear burning through the phenomenon of leaking out, solves the problem that exists among the background art.
The technical scheme of the utility model is that:
a slag discharging device of a steel rolling heating furnace comprises a slag discharging channel, a heating furnace, a slag outlet, a supporting plate and a slag discharging guide plate, wherein the slag discharging channel is vertically arranged at the bottom of the heating furnace, the slag discharging channel is formed by laying refractory bricks and masonry materials, the upper end of the slag discharging channel and the bottom of the heating furnace are built into an integral structure, the lower end of the slag discharging channel is provided with the slag outlet, the slag discharging guide plate which is obliquely arranged is arranged in the slag outlet, and the slag discharging guide plate is fixed at the lower end of the slag discharging channel through the supporting plate.
And an included angle between the slag discharge guide plate in the slag outlet and the central line of the slag discharge channel is 45 degrees.
The slag discharge channel is a chimney-shaped vertical pipeline built by refractory bricks and masonry materials.
The supporting plate and the slag discharge dredging plate are vertically arranged.
Adopt the utility model discloses, the waste residue in the heating furnace can directly fall to arrange the sediment through row's sediment passageway and dredge on the baffle to dredge the baffle along arranging the sediment and discharge to the outside, retrieve by artifical clearance again and do the reutilization. If the slag discharging device needs to be replaced, the original slag discharging device can be directly dismantled and built again, and the method is simple and convenient.
The utility model has the advantages that: the structure is simple, the manufacture is convenient, the operation can be completed by two persons for 8 hours, and the manufacture cost is only one tenth of that of the original device. In addition, in the using process, the phenomena of fire burning through and fire leakage cannot occur, the wear resistance of the refractory brick is strong, and the service life is prolonged by more than 3 times.
