Abstract
The utility model belongs to the technical field of the manufacture of smelting oxygen blowing appliances in metallurgical industry. A continuous oxygen blowing tube communicating device is formed by combining a tube sleeve brick with a circular diameter changing through hole and tightening loops together, wherein a hole diameter of the middle part of the through hole in the tube sleeve brick is reduced; transverse grooves are arranged near both ends of the through hole and are used for placing the tightening loops which are made of plastic films by containing liquid glue. Cinder, lime, wood dust, hemp thread, steel wires and glue are contained in a brick body of the tube sleeve brick. The end part of the tube sleeve brick is provided with a chamfer which is similar to a cone and is convenient for pushing in and pulling out an oxygen blowing tube. The tightening loops are in a circular ring shape. The continuous oxygen blowing tube communicating device is an ideal appliance which reduces the oxygen blowing cost of steel smelting to a great extent at present.
Description
The utility model is a kind of industrial production apparatus, belongs to the manufacturing technology field that smelts the oxygen blast apparatus in the metallurgical industry.
Existing steelmaking oxygen blowing operation generally adopts single oxygen lance to carry out oxygen blast; in order to delay the time that oxygen lance is melted; reduce the quantity consumed of oxygen lance; around the oxygen lance tube wall, be coated with the seat clay protective layer of 5 millimeters thick of having an appointment; but; along with continuous oxygen blast; when oxygen lance is melted to about 2 meters of residue length; because the influence of fire door high temperature; the oxygen blast workman has to discard this oxygen lance; and the oxygen lance that more renews continues oxygen blast; the oxygen lance that goes out of use accounts for the 25%--35% of whole oxygen lance consumptions, although the enterprise that has adopts the method for secondary recovery oxygen lance; through postwelding has been utilized the part oxygen lance again; but the oxygen lance to postwelding has obstruction and phenomenon of rupture more in the commissure, simultaneously, still can not avoid the situation of discarded about 25%--35% once more; and reclaim; the secondary operations expense of butt welding and transportation is also very high, causes the oxygen blast cost not descend significantly.
Goal of the invention of the present utility model is a kind of oxygen lance Communicating device of initiative, make existing list prop up separate type oxygen blast mode and change into many laddering oxygen blast modes, thereby a utilization rate of oxygen lance is brought up to 100%, avoid links such as all secondary recovery, improve working strength of workers, reduce the oxygen blast cost in the smelting process significantly.
The technical solution of the utility model is as follows:
Continous way oxygen lance Communicating device (see figure 1) is formed by pipe box brick that has circular reducing through hole and tight loop common combination.Pipe box brick inner via hole middle aperture is dwindled, and establishes transverse concave groove near the through hole two ends and is used for laying tight loop.Tight loop is to comprise liquid glue with plastic sheeting to make.Pipe box brick brick body contains cinder, lime, wood chip, flax silk, steel wire and glue.The end of pipe box brick is provided with chamfering (approximate cone), is convenient to the propelling of oxygen lance and withdraws from.Tight loop is circular.
The effect that pipe box brick inner via hole middle aperture is dwindled is: 1, can fastening insertion oxygen lance end wherein; 2, can strengthen the pressure of oxygen flow.Establish transverse concave groove near the pipe box brick inner via hole two ends and be used for laying tight loop so that oxygen lance is anchored in the pipe box brick.The full liquid glue of the inner storage of tight loop.The tight loop internal diameter is slightly less than the oxygen lance external diameter, and when oxygen lance inserts the pipe box brick, oxygen lance will expand the tight loop support to rub and break, viscose glue overflows immediately in the circle, solidifies rapidly under thermal environment, and oxygen lance and pipe box brick are bonded together, simultaneously, also play sealing function.
The utility model concrete structure and embodiment, the contrast description of drawings is as follows:
Fig. 1 is a front view of the present utility model.
Fig. 2 is a profile of the present utility model.
Fig. 3 is the profile of tight loop.
Among the figure, 1--is the pipe box brick, and 2--is a tight loop, and 3--is a liquid glue, the 4--oxygen lance.See Fig. 1, continous way oxygen lance Communicating device is combined by pipe box brick 1 that has circular reducing through hole and tight loop 2.Tight loop 2 is to comprise liquid glue 3 with plastic sheeting to make.During use, oxygen lance 4 inserts from the through hole at pipe box brick 1 two ends, can realize many laddering oxygen blast modes.Continuous fusing along with oxygen lance can continue to connect this Communicating device, inserts new oxygen lance again.Move in circles like this, make the oxygen blast operation successive.Through initial estimate, use the utility model and can reduce oxygen lance consuming cost about 1/3rd.
