Description
Technical Field
The utility model relates to a slag cleaning technical field, more specifically say, relate to a converter stove lower channel sediment cleaning device.
Background
The lower channel of the converter is mainly the only channel for transporting the converter slag or molten steel outwards, and the channel is a specific operation line of a slag ladle car and a ladle car. However, unexpected splashing exists in the normal smelting process of steel making, the tapping operation at the smelting end point and the production process of the converter, so that hot slag of the converter is accumulated on a lower channel of the converter. A small amount of dispersed hot slag can damage slag and a buggy ladle travelling cable on the channel; the hot slag is not cleaned in time and accumulated in a large amount, so that a great deal of adverse effects are caused to the continuous production of the converter, such as the blockage of the walking of a slag car/buggy ladle, the baking of the hot slag on equipment such as a slag/buggy ladle speed reducer and the like, the service life of the track is reduced by the high-temperature hot slag, and the accumulated slag falls into the two sides of the track, so that the elevation of the track and the outside ground is insufficient, and the safe production accident of derailment of the slag/buggy ladle can be caused. The traditional method for cleaning accumulated slag on the lower track of the furnace mainly adopts a manual cleaning mode and a loader-assisted cleaning mode, the cleaning is targeted, but the operation efficiency is low, the operation rate of the converter is influenced, and the safety risk of the operation under the furnace is high. Therefore, on the premise of ensuring stable and efficient smelting of the converter, the invention provides the device and the method for cleaning the accumulated slag in the lower channel of the converter, which have strong application significance, in order to improve the efficiency of cleaning the lower channel of the converter and avoid the safety risk of the operation under the converter.
Chinese patent No. CN 206069924U also discloses a slag removing shovel for a converter slag pit, which comprises a driving rod, a hydraulic cylinder and a slag shovel. Shovels the steel slag between the rails through the slag shovel, has simple structure, convenient use and low labor intensity, but cannot collect the steel slag which is shoveled. Chinese patent No. CN 202804176U discloses a slag ladle car with a slag cleaning function, which comprises a car body, a slag pusher and a supporting plate inclined towards the outside of the car. Utilize the slag pusher to push out the high temperature slag on the slag runner, cleared up the slag runner fast and conveniently, but this pushing away slag device obviously has not enough to the slag pit clearance degree of depth. Chinese patent No. CN203820832U also discloses a slag pushing device for a converter slag car, which mainly comprises an inclined push plate, a straight push plate, a fixed connecting plate, a bolt, a movable connecting plate, a hinged fork, a pin shaft, a positioning support block, a backing plate, a slag car, a track and an outer enclosing plate. The inclined push plate can effectively scoop up the steel slag accumulated on the slag channel between the two steel rails, so that the slag pushing resistance is greatly reduced, and the slag pushing effect is improved. The three cleaning devices play a certain positive role in cleaning between the rails, but the three devices can only clean accumulated slag between the rails, and the accumulated slag outside the rails cannot be cleaned or the cleaning capability is insufficient, so that the popularization and the application of the three cleaning devices are limited.
