Abstract
The utility model belongs to the technical field of steel-making refining equipment, and particularly relates to a hydraulic detachable furnace door device for an LF (ladle furnace) refining furnace. The furnace door opening device comprises a furnace door and is characterized by consisting of the furnace door, a shaft lug, a rotating shaft, a bearing seat, a hydraulic cylinder for opening the furnace door and a support; the pneumatic cylinder links firmly to connect on the support, and the pneumatic cylinder passes through the link plate and connects the pivot, welds two journal stirrup in the pivot, and journal stirrup and furnace gate adopt bolted connection, and there is thermal insulation material the inboard of furnace gate, furnace gate outside bottom welding balancing weight. The furnace gate cancellation water-cooling structure selects heat-resisting material, and the insulating layer is pour to inside, and the furnace gate is high temperature resistant, avoids leading to the production hidden danger that water leaks and lead to under the prerequisite of guaranteeing to use. The furnace gate head increases the balancing weight, and the stove furnace gate is closed by the dead weight to the pressure release, and the operation is simple, effective, reduces the fault point. The furnace door is connected with the shaft lug through the bolt, the structure is reasonable, the installation is simple, the disassembly is convenient, the inconvenience brought by production and maintenance is greatly reduced, and the production efficiency is effectively improved.
Description
Technical Field
The utility model belongs to the technical field of steel-making refining equipment, and particularly relates to a hydraulic detachable furnace door device for an LF refining furnace.
Background
Traditional LF refining furnace gate adopts integral type water-cooling structure more, though can satisfy the user and use, nevertheless damages easily at long-term high temperature work water-cooling structure and leaks, and demolishs the change difficulty, seriously influences production.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the defects of the traditional structure and provide the hydraulic detachable furnace door device for the LF refining furnace, which is reasonable in structure, high-temperature resistant and convenient to detach and replace.
The technical solution of the utility model is as follows: the hydraulic detachable furnace door device for the LF refining furnace comprises a furnace door and is characterized by consisting of the furnace door, a shaft lug, a rotating shaft, a bearing seat, a hydraulic cylinder for opening the furnace door and a support; the pneumatic cylinder links firmly on the support, and the pneumatic cylinder passes through the connecting plate and connects the pivot, welds two hangers in the pivot, and the hangers adopts bolted connection with the furnace gate, and the inboard of furnace gate has thermal insulation material, furnace gate outside bottom welding balancing weight.
In the above scheme, the method further comprises:
the inner side of the furnace door is welded with an anchoring hook, and the heat insulation material is knotted.
The outside of the furnace door is added with a reinforcing rib for ensuring the strength.
The rotating shaft is of a hollow shaft structure.
The utility model has the advantages that: 1. the hollow tube processing is selected in the furnace gate pivot, and good heat dissipation can effectively prevent because of the thermal deformation that high temperature leads to under the prerequisite of assurance intensity. 2. The furnace door cancels the water-cooling structure, selects heat-resisting material, and the insulating layer is pour to inside, and the furnace door is high temperature resistant, avoids leading to the production hidden danger that leaks and lead to under the prerequisite of guaranteeing to use. 3. The counterweight block is added at the head part of the furnace door, the furnace door is closed by the dead weight during pressure relief, the operation is simple and effective, and the fault points are reduced. 4. The furnace door and the shaft lug are connected through bolts, the structure is reasonable, the installation is simple, the disassembly is convenient, the inconvenience caused by production and maintenance is greatly reduced, and the production efficiency is effectively improved.
Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
