The present invention relates to a kind of fan-shaped section of conticaster, particularly a kind of separable fan section of conticaster.
The conticaster of countries in the world continuous casting steel billet all is to adopt the monoblock type fan-shaped section at present, and the framework up and down of fan-shaped section, last bottom pinch roll and four root posts connect into an inseparable integral body.There are the following problems for the monoblock type fan-shaped section: 1. " stagnate base " difficult treatment, " heavy throwing " easy damaged equipment: in a single day " base stagnates " phenomenon takes place during continuous casting steel billet, chill slab string is in fan-shaped section, fan-shaped section can't integral body hang out, can only adopt the hard draw method, the arc continuous casting slab of tens meters long chill moulding is pulled out from the horizontal segment direction, and all driven rollers that then will start in the roller row carry out " heavy throwing ", can cause the pinch roll of each fan-shaped section and bearing excess load to damage.2. " to arc " difficulty is big, error is big, and waste time and energy: all changed fan-shaped section after, must carry out " to arc " again and adjust roll gap, then need the little chap personnel to creep on the fan-shaped section between the bottom pinch roll, crouch to lie in the roll gap difficultly and measure gap between " form tool " lower camber side and every bottom pinch roll roll surface with clearance gauge, note up to a hundred gap widths, adjust then, measurement clearance again, repeated multiple times just can be adjusted, waste time and energy, very difficult, and like this to the result of arc, error is big.When 3. meeting the bleed-out accident by chance, difficult treatment: when meeting bleed-out by chance, necessity stops watering, and stops watering then and causes " base stagnates ", and each bleed-out all will be spent tens hours and shut down processing.4. device structure complexity, equipment tonnage is heavy: monoblock type fan-shaped section complex structure, determining of its each parameter is also very complicated, and the weight of each fan-shaped section reaches 48 tons, and the driving lifting capacity should be greater than 50 tons.
The object of the present invention is to provide a kind of improved continuous casting machine fan-shaped segment, promptly is separable fan section of conticaster, thereby solves the problem of above-mentioned existence.
In order to achieve the above object, the present invention adopts following technical proposals: the same framework and the last bottom pinch roll up and down of including with prior art of the present invention.Be characterized in: be connected with the structure that removably connects between the framework up and down.In use, " base stagnates ", bleed-out taking place or change fan-shaped section needs " to arc " to measure when adjusting, and detachable upper frame hangs out upper frame and the top pinch roll that connects on it, thereby solves four problems of above-mentioned existence.
The structure that removably connects between the framework up and down of the present invention can be designed as hydraulic locking mechanism: four root posts on the underframe are hinged and have the check lock lever of locking discount, the locking bail of locking discount and upper frame top links, locking bail is connected with the piston rod of hydraulic cylinder on being connected upper frame, and locking discount lower surface is supported on the skewback on the upper frame.Then operate hydraulic cylinder, pulling locking discount slides on skewback, then can lock or unclamp upper frame, mounts and dismounts.Can certainly adopt controllable motors to replace above-mentioned hydraulic cylinder, the output shaft of motor connects a tapped sleeve pipe, sleeve pipe revolves joins a screw rod, the outer end of screw rod connects above-mentioned locking bail, then operate controllable motors, pulling locking discount slides on skewback, thereby locking or unclamp upper frame mounts and dismounts.The structure that removably connects between the framework can also be designed to the bolt and nut syndeton up and down: thread segment is arranged at the top of four root posts on the underframe, the thread segment of column passes four corresponding on upper frame perforation, overlap upper gasket then, revolve the thread segment of joining column with nut, thereby can tighten and unclamp upper frame, mount and dismount.But the employing bolt nut structure will comparatively be wasted time and energy with pull four nuts than great strength during mounting or dismounting.
The present invention compared with prior art, have following conspicuous outstanding feature and remarkable advantage: the present invention adopts the structure that removably connects to the connection between the framework up and down, upper frame can be separated with the underframe dismounting, monoblock type fan-shaped section of the prior art has been carried out outstanding improvement.Because this improvement, upper frame can separate with the underframe dismounting, when " base stagnates " and bleed-out accident occurring, only need hang out upper frame and connect top pinch roll on it, can cut at an easy rate and be trapped in the chill steel billet in the fan-shaped section and hang out, need not to carry out " heavy throwing ", also can not damage pinch roll and bearing, can fix a breakdown rapidly, time saving and energy saving; When carrying out " to arc " and adjusting roll gap, carry out " to arc " and adjustment behind the top pinch roll on hanging out upper frame and being connected it, laborsaving saving time, it is also high to adjust precision; Because only need hang out upper frame and connect top pinch roll on it, its weight is much smaller than the weight of whole fan-shaped section, the lifting capacity of special-purpose driving also can correspondingly greatly reduce; Because upper frame detachably separates with underframe, fan-shaped section simple in structure reduces the manufacturing cost of fan-shaped section itself.In the use, installation and removal are also convenient.
