Abstract
The utility model relates to a step-by-step slot type continuous casting machine which integrates the advantages of the wheel belt type continuous casting machine and the common horizontal continuous casting machine together. The utility model adopts an interrupted blank withdrawal mode and a crystallizer composed of a plurality of trapezoidal crystallization slots (3) and steel belts (5) without heads. The crystallizer and the casting blank run at the same time in the process of casting, so that the problem of breaking the prehardening blank shell can not occur. The position of the metal level in the crystallizer does not need to be controlled when molten metal flows into the crystallizer through a sealed water inlet, so that the metal can not be oxygenized. When small square blanks of 52*52 to 70*70 are cast by the utility model, the blank output speed can reach to 15 m/min to 25 m/min, which is three to five times faster than that of the arc-shaped continuous casting machine or the common horizontal continuous casting machine.
Description
The present invention is that a class has the step motion crystallizer, is particularly suitable for the horizontal caster of little square billet.
Existing its crystallizer motion mode of conticaster has three kinds, and first kind is the high frequency double vibrations, and as circular-arc type continuous casting machine crystallizer (as USA2947075), its Oscillation Amplitude is 3 to 5 millimeters; Second kind is movement at the uniform velocity, and as round belt continuous casting machine crystallizer (as J56-45254), metal base and the crystallizer cast on this conticaster do not have relative motion, does not have resistance of billet withdrawal and pulls open initial set base shell problem; The third is the crystallizer of fixing, cooperation is to be interrupted throwing, the crystallizer of using as the mean level conticaster (as J55-22428), the throwing amplitude also has only 3 to 15 millimeters, but the crystallizer of this horizontal caster and tundish close-coupled, molten metal flows into crystallizer in the passage in close spare time, avoided the oxidation of molten metal.And the system that does not need metal bath surface position in the crystallization control.More than three kinds of conticasters when casting little square billet, ejection speed all is no more than 5m/min, production capacity is all less.
The present invention combines the advantage of round belt continuous casting machine and mean level conticaster, has adopted the step motion crystallizer and has been interrupted the throwing mode, and the stepping amplitude is 150 to 450 millimeters, not only improves slab quality and has improved production capacity significantly.
The step-by-step movement crystallizer is by the end to end trapezoidal crystallization tank (3) of straight line and steel band without a head (5) formation of circular flow of being linked to be of plurality of sections, see shown in Figure 1, trapezoidal crystallization tank (3) is made step motion towards the throwing direction, steel band (5) is pressed on frictionally and crystallization tank (3) synchronous operation on the notch of crystallization tank (3), crystallization tank (3) walks to the preceding position (3 ') that falls to of drawing device (6), progressively return to latter end position (3 ' e), rise to the step motion of back, position (3e) recovery again towards the throwing direction, treat to converge with steel band (5) and constitute crystallizer, its effective length is circular-arc type continuous casting machine or mean level conticaster crystallizer three to five times.Crystallizer and strand synchronous operation in casting cycle, thereby not having the initial set base shell problem of pulling open yet, the present invention simultaneously also adopts airtight casting system, makes metal flow into crystallizer through the airtight mouth of a river, do not need crystallization control device inner metal liquid face to draw and put, avoided the oxidation of molten metal yet.
The step motion of crystallizer matches and mechanical interlocking with the interruption action of drawing device (6), has guaranteed the harmonious of motion, a little higher than throwing amplitude of stepping amplitude.The difference of interior amplitude of unit interval equals the amount of contraction behind the solidification of molten metal.In the stepping of crystallization tank and be interrupted in the period of motion of throwing, it advances and the time that stops can to equate, also can be not wait.The base shell of initial set weakness can continue to solidify in the time of halting and thickens, and its intensity can be greater than the cohesive force of initial set base shell forward position and end, the airtight mouth of a river, thereby guarantees that initial set base shell can not stick in end, the mouth of a river.When casting 52 * 52 to 70 * 70 little square billet with the present invention, ejection speed can reach 15 to 25m/min, is circular-arc type continuous casting machine or mean level conticaster ejection speed three to five times.
Molten metal in tundish (1) is by flowing in the crystallizer with the crystallizer mouth of a river (2) movingly, because slit movingly is very little, molten metal has certain surface tension again, so molten metal can not flow out from slit movingly.The cooling of water cooling plant (7) water spray is arranged in the outside of crystallization tank (3) and steel band without a head (5).The crystallization tank stepping mechanism acts on the boss (9) of crystallizer and goes up (see figure 2), makes it stepping forward in the guide rail (not shown).The inwall and the steel band without a head (5) that are in the dovetail groove (3) of position (3e) all scribble refractory material and molten metal sealant towards the surface of molten metal; lubricated on the one hand and protection crystallizer makes it to be easy to mould adobe blocks, and also slits between the crystallization tank and the mouth of a river and two crystallization tank joints is sealed simultaneously.
Step-by-step movement crystallizer of the present invention also can be used for round belt continuous casting machine can be linked to be wheel shape with trapezoidal crystallization tank (3), and steel band without a head (5) is made the arc that matches with the crystallization sheave.
