Description
Technical field
The present invention relates to a kind of fountain water cooled furnace body, belong to technical field of metallurgical equipment.
Background technology
Water cooled furnace body is that the water-cooled piece that is made into by the polylith seamless steel pipe is assembled always, and water flowing cooling in the seamless pipe keeps furnace shell receiving not produce distortion under the situation of high temperature.Because the cooling water in the seamless pipe has pressure; In case lean on the seamless pipe of furnace body inside crackle to occur or break; The cooling water of band pressure can meet with the furnace high-temperature molten steel and produce explosion accident, and because its sealing property of furnace shell that polylith seamless pipe water-cooled is but formed is relatively poor, the environment for use of furnace shell is abominable; Form by polylith seamless pipe assembly owing to former water cooled furnace body again; So the original structure furnace shell is very short service life, particularly this version is difficult for maintenance and safeguards, so use cost is also than higher.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, provide a kind of non-tubular type, simple in structure, be convenient to keep in repair, fountain water cooled furnace body that security reliability is good.
The objective of the invention is to realize like this: a kind of fountain water cooled furnace body; It comprises furnace shell inwall, furnace shell base plate and furnace shell outer wall; Be provided with the spray pipe-line system between said furnace shell inwall and the furnace shell outer wall; Said furnace shell outer wall also is provided with water return outlet and water inlet, and said spray pipe-line system is connected with water inlet, and said water return outlet is positioned at the bottom of furnace shell outer wall.
Said furnace shell outer wall is provided with a plurality of dodge gates.
The joint portion of said furnace shell top and bell is provided with refractory material.
Compared with prior art, the present invention has following beneficial effect:
1, security: water cooled furnace body utilizes the cool water shower system in the furnace shell interlayer that inner layer steel plate is sprayed cooling because internal layer is to be rolled by high temperature resistant steel plate to form.Because of the water of spray on the furnace shell inner layer steel plate is stress-free; And the furnace shell housing is again vertical the placement; Water in the spray cooling on the furnace shell steel plate flows in the water leg of bottom along lining steel plate and forces sucking-off by pump, and the water of sucking-off returns into whole industrial water system and carries out recycle or directly emit.Even occur crackle or broken hole on the furnace shell inner layer steel plate, a small amount of shower water that does not have pressure can't get in the high temperature furnace hall through crackle or broken hole, and therefore its security of water cooled furnace body of this pattern is cocksure.The furnace shell internal layer of furnace shell is welded with the bulk high temperature resistant steel plate, and the thickness of the few and steel plate of weld seam far surpasses the wall thickness of pipe, so the whole rigidity of furnace shell improves a lot.
2, service life: its inwall of fountain water cooled furnace body is rolled by resistant to elevated temperatures steel plate and is welded; Except that the steel plate thickness that uses than the wall thickness of pipe want thick; Rolling and forming its whole rigidity and sealing behind the double Shell is that the water cooled furnace body institute of tubular type is incomparable; Owing to be easy to therefore can use for a long time with regard to repairing by internal furnace shell steel plate.
3, energy-conservation: since the furnace shell liner by steel plate roll form after, its furnace shell that sealing of furnace high-temperature is formed than the water-cooled piece is greatly improved, furnace high-temperature is difficult for leaking, and makes the peripheral working environment of furnace shell obtain bigger improvement; And since total water-cooled but area much smaller than the total water-cooled of calandria but area S pipe/S spray ≈ 1.6; Owing to need film-cooled heat to reduce; The return water temperature of fountain water cooled furnace body permission cooling water is up to 85 ℃ in addition; And calandria furnace shell leaving water temperature is merely about 35 °, and its water is merely 1/5 of former tubular type furnace shell water consumption, thus the purpose that realization is saved water and energy and increased economic efficiency.
4, owing to guaranteed reliably in the security and service life of furnace shell of the present invention, therefore significantly reduced the user to this overhaul of the equipments, change required hot downtime.
5, for preventing that the molten steel formation that causes this position to splash is up easily condensed, adhesion because molten steel splashes in steelmaking process for furnace shell and bell binding site; For this reason furnace shell and the utilization of bell binding site can steel bonding refractory material be filled in the top ends of furnace shell; Solved the molten steel that splashes effectively to the influence that this position produces, more smooth and easy when making bell need translation reinforced.
