Abstract
The utility model relates to a tundish long nozzle quickly changed device which is characterized in that a guide screw (1) is sleeved with a screw nut (3) together in a perforating way by a fixed sleeve (2), the other end of the guide screw (1) is arranged in a seating cover (4), support poles (5) are respectively arranged at the two sides of the screw nut (3), connecting rods (6) are respectively arranged on the two support poles (5) and are capable of rotating around the support poles (5), a rotatable sliding rod (7) is arranged between the two connecting rods (6), the end parts of the two connecting rods (6) are respectively connected with lifting rods (9) by making use of pin shafts (8), the end parts of the two lifting rods (9) are fixed on a sliding sleeve (10), an inner sliding sleeve (11) that is matched with the sliding sleeve (10) is arranged in the sliding sleeve (10), and lifting hooks (13) are arranged on the sliding sleeve (10) by a pin shaft (12). The tundish nozzle quickly changed device has the advantages that the lower nozzle can be changed quickly, the consumption cost of the nozzle can be largely reduced, the casting efficiency can be improved, and the time for changing the nozzle and the steel ingot cost can be reduced.
Description
Technical field
The utility model belongs to metallurgical technology field, and steel ingot middle water containing opening fast replacing device waters in especially a kind of company.
Background technology
After the seventies in 20th century, the continuous casting technology development is swift and violent, and continuous casting has substituted the conventional die castings technology more than 90%, but in the field of ask for something variety steel and large parts, as industries such as machinery, electric power, military projects, static ingot also has its vast market.For the steel ingot more than 50 tons, all adopt to go up and annotate technology, according to the steel ingot ingot shape, utilize two bags or many Baogangs water to inject ingot mould through tundish, realize the continuous pouring of steel ingot.At present both at home and abroad the pouring technology of steel ingot adopts more that single stove molten steel makes a bet, the steel ingot that can not pour into a mould single stove molten steel, usually adopt continuous casting technology, many Baogangs water even waters, connect to water tundish must be set, tundish is arranged with long nozzle, and according to the difference of steel ingot ingot shape size, long nozzle length has 2-5 rice different series specification.In the casting process,, often pour into a mould about 45 minutes and must change the mouth of a river because molten steel is serious to washing away of the mouth of a river, because the mouth of a river is an overall structure, weight is big, and the mouth of a river changes that not only process is longer, and mouth of a river material is special, is worth costliness, and frequent the replacing causes the steel ingot cost to rise.
Summary of the invention
At the problems referred to above, task of the present utility model provides a kind of short tundish long nozzle fast replacing device of time of changing.Based on mouth of a river length and production cost problem, our mouth of a river is set to two sections, top is the mouth of a river, top, the bottom is immersed molten steel and is partly claimed the mouth of a river, bottom, the zirconium matter moulding submersed nozzle of anti-rapid heat cycle, antiscour is adopted at the mouth of a river, bottom, the magnesium carbonaceous injecting pipe brick moulding mouth of a river is adopted on top, and the mouth of a river, top is fixed on the tundish lower end, utilizes tundish long nozzle fast replacing device that the mouth of a river, bottom now is connected fast, changes with the upper water cause for gossip.Said tundish long nozzle fast replacing device is achieved in that a leading screw is through with nut sleeve by fixed cover, the other end of leading screw is arranged in the cover for seat, the screw both sides are respectively equipped with pole, two poles are gone up installing connecting rods respectively, and connecting rod can rotate around pole, be provided with rotating slide bar between two connecting rods, the end of two connecting rods utilizes bearing pin and elevating lever to link together respectively, the end of two elevating levers is fixed on the sliding sleeve, cooperate with it in the sliding sleeve and be provided with inner sliding sleeve, be provided with suspension hook by bearing pin on the sliding sleeve, the number of suspension hook is at least two, is combined with the mouth of a river, bottom cover with suspension hook.For convenient fixing, a fixed support is set on the fixed cover.
The course of work of the present utility model is such: during use, the utility model is fixed on the corresponding site at the mouth of a river, top by cover for seat and fixed support, and inner sliding sleeve is fixed on corresponding position simultaneously.In changing the mouth of a river, bottom process, the leading screw that at first turns clockwise, screw outwards move, drivening rod clockwise rotates simultaneously, elevating lever moves down, and by sliding sleeve suspension hook is thrown off, and throw off at the mouth of a river, bottom and the mouth of a river, top, utilize instrument to remove the bottom and damage the mouth of a river, again more renew the mouth of a river, bottom, the new mouth of a river, bottom is lifted in the mouth of a river, top by the mouth of a river, bottom cover, is rotated counterclockwise leading screw then, screw moves to the inside, by elevating lever the mouth of a river, bottom and the mouth of a river, top is connected.The mouth of a river, top is designed to the primary and secondary structure with being connected of the mouth of a river, bottom, is convenient to sealing.
The mouth of a river, the utility model fast changeable bottom significantly reduces mouth of a river consumption costs, reduces the mouth of a river and changes the time, improves cast efficient, reduces the steel ingot cost.The utility model also can be used for the quick replacing at the mouth of a river under the continuous casting tundish.
