Abstract
The utility model belongs to the sealed fabric construction's of steel mill continuous slab casting dummy ingot head improvement, especially a with cooperate fabric construction of continuous slab casting dummy ingot head of crystallizer, include with crystallizer matched with dummy ingot head, setting up the asbest rope in dummy ingot head and crystallizer matched with gap, setting up the iron nail bits layer that 10 -15mm is thick on the top surface of dummy ingot head, setting up the net cooling piece on iron nail bits layers, the structure of net cooling piece be by the net spare of bar formation above it below with difference rigid coupling the cube steel bloom. The utility model discloses it is rational in infrastructure, can guarantee to open when watering and to solidify fast with the molten steel of dummy ingot head contact, the cooling piece cooling effect is good, and use not happening start bleed -out accident can improve the operation rate of start success rate, conticaster, easy operation, the cloth is fast, can reduce workman's intensity of labour, improves work efficiency.
Description
Technical field
The utility model belongs to the improvement, particularly a kind of fabric construction of the sheet billet continuous casting dummy bar head that matches with crystallizer of steel mill sheet billet continuous casting dummy bar head sealing fabric construction.
Background technology
Dummy bar 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 " the interior end ", after cast starts, molten steel solidification, together with condensing in dummy bar head, dummy bar is drawn by withdrawal straightening machine, strand continuously from crystallizer pull-out, until dummy bar head is separated with strand by withdrawal straightening machine rear, enter dummy bar storing device.Dummy bar head needs to fill up with the gap of asbestos cord by surrounding, then puts into cooling piece and carry out cloth after sending into crystallizer, ensures to open the molten steel rapid solidification contacted with dummy bar head when watering, and can be pulled out crystallizer.Dummy bar head surrounding gap is filled up with asbestos cloth after sending into crystallizer by dummy ingot, then adding iron nail bits, when pouring into a mould low-alloy steel because the more general steel of temperature is low so cold burden is more sparse, pouring into a mould general steel then just in time contrary.Let cool material fortress real, otherwise easy bleed-out.Start bleed-out phenomenon is easily there is in the method for the start dummy bar head of crystallizer sealing that current sheet billet continuous casting adopts when just using, although make start bleed-out phenomenon is not easily occurring in follow-up improved, process, but from cut strand head viewed from, waste many start cold burdens, part start cold burden is also stuck in fan row section, causes the defect that strand scratches.
Utility model content
The purpose of this utility model is the fabric construction providing a kind of sheet billet continuous casting dummy bar head that matches with crystallizer, it is rational in infrastructure, can ensure to open the molten steel rapid solidification contacted with dummy bar head when watering, cooling piece good cooling results, there is not start bleed-out accident in use procedure, can improve the operating rate of start success rate, conticaster, simple to operate, cloth speed is fast, can reduce the labour intensity of workman, increase work efficiency.
The purpose of this utility model is achieved in that a kind of fabric construction of the sheet billet continuous casting dummy bar head that matches with crystallizer, comprise the dummy bar head matched with crystallizer, in the gap that dummy bar head matches with crystallizer, asbestos cord is set, the end face of dummy bar head arranges the iron nail bits layer that 10-15mm is thick, above arrange grid cooling piece at iron nail bits layer, the structure of grid cooling piece is that the grid member that is made up of reinforcing bar is above it and distinguish affixed cube bloom below.
The utility model purpose of design is to improve start success rate and operating efficiency, reduces supplies consumption.
Main improvement content is as follows:
1, with reinforcement fabrication grid cooling piece, grid welds two pieces of square blooms up and down.
2, first spread the iron nail bits that one deck 10-15mm is thick after having filled in dummy ingot, emphasis point is the top of asbestos cord.
3, after dummy bar head has sealed, in the both sides of dummy bar head, novel cooling piece is placed respectively.
Main improvement effect:
1, after the new-type sealing distributing method of use, simple to operate, cloth speed is fast, improves efficiency.
2, eliminate the operation of a large amount of band iron of cutting as coolant, worker's labour intensity declines.
3, novel cooling piece good cooling results, there is not start bleed-out accident in use procedure, improves the operating rate of conticaster.
4, at cut base head, cooling piece substantially all melts, and does not occur that cold burden drops the phenomenon be stuck in fan-shaped section, improves the start success rate of conticaster.
5, cooling piece is carrier structure, can not disperse, thus avoids the damage to copper plate of crystallizer.
6, novel cooling piece adaptability is comparatively strong, and each steel grade can use.
The utility model is rational in infrastructure, ensure that the molten steel rapid solidification opened and contact with dummy bar head when watering, cooling piece good cooling results, there is not start bleed-out accident in use procedure, improve the operating rate of start success rate, conticaster, simple to operate, cloth speed is fast, the passable labour intensity reducing workman, increases work efficiency.
Accompanying drawing explanation
Be further described the utility model below in conjunction with accompanying drawing, Fig. 1 is main TV structure schematic diagram of the present utility model, and Fig. 2 is the main TV structure schematic diagram of grid cooling piece.
Detailed description of the invention
A kind of fabric construction of the sheet billet continuous casting dummy bar head that matches with crystallizer, as shown in Figure 1 and Figure 2, comprise the dummy bar head 2 matched with crystallizer 1, in the gap that dummy bar head 2 matches with crystallizer 1, asbestos cord is set, the end face of dummy bar head 2 arranges the iron nail bits layer 3 that 10-15mm is thick, above arrange grid cooling piece 4 at iron nail bits layer 3, the structure of grid cooling piece 4 is that the grid member that is made up of reinforcing bar 5 is above it and distinguish affixed cube bloom 6 below.The diameter of reinforcing bar 5 is 3-6mm.
Claims (2)
1. the fabric construction of the sheet billet continuous casting dummy bar head that to match with crystallizer, comprise the dummy bar head (2) matched with crystallizer (1), in the gap that dummy bar head (2) matches with crystallizer (1), asbestos cord is set, it is characterized in that: iron nail bits layer (3) that 10-15mm is thick is set on the end face of dummy bar head (2), on iron nail bits layer (3), grid cooling piece (4) is set, the structure of grid cooling piece (4) is the grid member that is made up of reinforcing bar (5) affixed cube bloom (6) respectively above it and below.
