Abstract
The utility model belongs to the improvement of slab caster dummy bar head construction, especially a slab caster's detachable dummy ingot head, including having the dummy ingot head of dovetail, left halfbody and the right halfbody of structure for cut apart into mutual symmetry along dummy ingot head dovetail longitudinal center line of detachable dummy ingot head is wherein setting up the breach recess on the bottom surface of half dovetail of left halfbody, setting up on the bottom surface of half dovetail of right halfbody with the breach recess matched with boss of half dovetail of left halfbody, make left and right halfbody put together through boss and the cooperation of breach groove phase. The utility model discloses it is rational in infrastructure, connect, separation convenient operation, opening the process of watering if under the condition of dummy ingot head and molten steel adhesion, can guarantee continuous casting billet and dummy bar separation, guarantee conticaster normal operating, to the dummy ingot head dovetail groove clearance convenience that the adhesion condition appears, can reduce the worker and change dummy ingot head intensity of labour, the dummy ingot trades the number of times first watch to be reduced by a wide margin, can improve the operation rate of conticaster.
Description
Technical field
This utility model belongs to the improvement of Slab Caster Dummy Bar head construction, the detachable dummy bar head of a kind of slab caster.
Background technology
Dummy bar of continuous casting machine is made up of dummy bar head, transition piece and shaft.Before cast, dummy bar head and section transitions part enter crystallizer, form crystallizer mobilizable " inner bottom ", after cast starts, the dovetail groove in molten steel solidification, with dummy bar head is coagulated together, dummy bar is drawn by withdrawal straightening machine, strand is pulled out from crystallizer continuously, until dummy bar head is separated with strand by withdrawal straightening machine rear, enters dummy bar storing device.
Original dummy bar head is overall structure, if open water process dummy bar head occur seal bad in the case of, often occur that dummy bar head and the situation of molten steel adhesion, dummy bar head and continuous casting billet cannot separate, make de-ingot failure, have undesirable effect conticaster is properly functioning.
Steel-making continuous casting process is certain service life owing to bakie working lining has, it is thus desirable to periodically restart cast, start needs to send into dummy bar crystallizer every time, and during start, dummy ingot head dovetail groove is connected with molten steel, then by dummy bar by strand traction pull-out crystallizer.
The subject matter that tradition monoblock type dummy bar head exists is as follows:
If 1, open water process dummy bar head occur sealing bad in the case of, often occur that dummy bar head and the situation of molten steel adhesion, dummy bar head and continuous casting billet cannot separate, make the failure of de-ingot, have undesirable effect conticaster is properly functioning.
2, for occurring that the dummy bar head dovetail groove of adhesion situation cannot be carried out cleaning, the dummy bar head that can only more renew, making dummy bar head consumption big, spare part is costly.
3, changing dummy bar head needs conticaster to shut down, and affects the operating rate of conticaster.
4, changing dummy bar head needs operator to install in secondary cooling zone, and labor intensity is higher, circumstance complication in secondary cooling zone, and worker operates at this and there is potential safety hazard.
Utility model content
The purpose of this utility model is to provide the detachable dummy bar head of a kind of slab caster, it is rational in infrastructure, connection, lock out operation are conveniently, open the process of watering if there is dummy bar head and molten steel adhesion in the case of, it is ensured that continuous casting billet separates with dummy bar, it is ensured that conticaster is properly functioning, convenient for occurring that the dummy bar head dovetail groove of adhesion situation is cleared up, can reduce worker and change dummy bar head labor intensity, dummy bar head is changed number of times and is greatly reduced, and can improve the operating rate of conticaster.
The purpose of this utility model is achieved in that the detachable dummy bar head of a kind of slab caster, including the dummy bar head with dovetail groove, the structure of detachable dummy bar head is to be divided into symmetrical left halfbody and right halfbody along dummy bar head dovetail groove longitudinal centre line, wherein breach groove is set on the bottom surface of left halfbody half dovetail groove, the bottom surface of right halfbody half dovetail groove arranges the boss of breach fit depressions with left halfbody half dovetail groove, makes left and right halfbody combine by boss and breach fit depressions.
Principle of the present utility model is: 1, be designed as by dummy bar head detachable, uses dovetail groove to connect between 2 parts, and connection, lock out operation are conveniently.
Improvement effect:
1, can quickly separate if there is dummy bar head and the situation of molten steel adhesion, dummy bar head 2 part opening the process of watering, first ensure that continuous casting billet separates with dummy bar, it is ensured that conticaster is properly functioning.
2, convenient for occurring that the dummy bar head dovetail groove of adhesion situation is cleared up, complete the reinstalling of internal cleaning is fixed, it is not necessary to changes dummy bar head, can reduce dummy bar head consumption, reduces spare part expense.
3, dummy bar head replacing number of times is greatly reduced, and can improve the operating rate of conticaster.
4, dummy bar head cleaning, return and pretend industry and can carry out with off-line, improve the working environment of worker, labor intensity can be reduced, it is ensured that the safety of worker.
This utility model is rational in infrastructure, connection, lock out operation are conveniently, open the process of watering if there is dummy bar head and molten steel adhesion in the case of, ensure that continuous casting billet separates with dummy bar, ensure that conticaster is properly functioning, convenient for occurring that the dummy bar head dovetail groove of adhesion situation is cleared up, reduce worker and change dummy bar head labor intensity, dummy bar head is changed number of times and is greatly reduced, and improves the operating rate of conticaster.
Accompanying drawing explanation
Being further described this utility model below in conjunction with accompanying drawing, Fig. 1 is this utility model perspective view.
Detailed description of the invention
A kind of detachable dummy bar head of slab caster, as shown in Figure 1, including the dummy bar head with dovetail groove, the structure of detachable dummy bar head is to be divided into symmetrical left halfbody 1 and right halfbody 2 along dummy bar head dovetail groove longitudinal centre line, wherein breach groove is set on the bottom surface of left halfbody 1 half dovetail groove, the bottom surface of right halfbody 2 half dovetail groove arranges the boss 3 of breach fit depressions with left halfbody 1 half dovetail groove, makes left and right halfbody 1,2 combine by boss 3 and breach fit depressions.
Claims (1)
