Description
Technical field
The utility model is related to online strip plate temperature-compensating technology arrangement, especially a kind of DC53 mould steel strip plate is warm online
Degree compensation technology arrangement.
Background technology
DC53 mould steel category high-carbon ledeburite type cold work die steels, band steel is generally through ingot casting → rolling (or forging) cogging
→ annealing → rolls (or forging) → anneal again.Eutectic carbide in DC53 steel ingots is coarse and stablizes, and must be added by heat
Work keeps it broken as far as possible and is evenly distributed.But DC53 resistances of deformation are high, and hot processing temperature narrow range, thermoplastic region about exists
1180±25℃.In order to which utmostly broken and uniform eutectic carbide, DC53 steel ingot coggings use the moderate finite deformation of multi-pass
Amount rolling, increases with passage, and rolled piece is elongated, and temperature reduction makes steel billet brittleness increase, and is particularly susceptible generation edge cracks, must mend temperature
After could continue to roll.
In the prior art, it heats stove heat frequently with off-line secondary or independent off-line arrangement mends warm device or Configuration Online is mended
Warm device carries out breakdown bar to mend temperature.Off-line secondary heating stove heat cannot efficiently use waste heat, increase lifting and transport
Time；Independent off-line arrangement, which mends warm device, can not make full use of waste heat, and it is larger to mend warm plant investment；Configuration Online mends temperature dress
Though waste heat can be utilized by setting, it is big and complicated to mend warm plant investment.
Therefore, how to overcome the warm disadvantage of benefit in the prior art, be those skilled in the art's technical problem urgently to be resolved hurrily.
Invention content
The purpose of the utility model is to overcome off-line secondary heating stove heat or the warm device of independent off-line arrangement benefit or online
The disadvantage that warm device mends breakdown bar temperature is mended in configuration, and realization requires stringent DC53 mould steel strip plates to roll hot processing temperature
Online temperature-compensating is carried out, and a kind of online temperature-compensating technology arrangement of mould steel strip plate is provided.
What the purpose of this utility model was realized in：A kind of online temperature-compensating technology arrangement of mould steel strip plate, including
The pusher that is sequentially arranged, heating furnace, the transfer roller groups being arranged in roll stand, the vertical miller across being arranged in roll stand, height
Pressure dephosphorizing machine automatically controlled sweeps phosphorus machine and flat roll mill, it is characterised in that：It is provided at least one set in the burner hearth of the heating furnace and pushes away steel
Stick group, the transfer roller groups are divided into rolling transfer roller and melt down transfer roller, and the rolling transfer roller is distributed on the roll stand of roll line
On, roll shaft is vertical with the plug for outlet of heating furnace, melts down two rolling transfer rollers that transfer roller is arranged at heating furnace plug for outlet
Between, roll shaft is parallel with the plug for outlet of heating furnace, and quantity is corresponding with rod iron group is pushed away.
The heating furnace is pusher-type furnace.
The rod iron group that pushes away is made of two row, the round rod iron that several length are 250~280mm, is separately positioned on and is added
On sliding rail in hot stove burner hearth.
The transfer roller that melts down is arranged for liftable.
The course of work of the utility model is：The double interval of steel ingot, which is placed in, to push away in rod iron group, and pusher pushes away rod iron
Group makes the steel ingot for having arrived preset temperature remove heating furnace, into roll line.Into roll line steel ingot through roll transfer roller sequence
It send to vertical miller and flat roll mill rolling, after rolling the roads N, melts down transmission through rolling transfer roller and being recycled at furnace outlet
Roller, melts down transfer roller rise, and the steel billet of temperature to be compensated is returned to the compensation temperature in rod iron group that pushes away in heating furnace, completes one
Secondary temperature-compensating.Steel billet after compensation temperature pushes away rod iron through pusher and removes heating furnace, is again introduced into roll line, rolling
Transfer roller by the strip plate after compensation temperature be sequentially presented to vertical miller, high pressure dephosphorizing machine, it is automatically controlled sweep phosphorus machine and flat roll mill, through vertical
Roller mill rolling on edge → high pressure dephosphorizing machine dephosphorization → automatically controlled is swept after phosphorus machine sweeps phosphorus → flat roll mill flat-rolled, and final size is rolled into
DC53 Flat Die Steels.
Compared with prior art, the utility model arrangement effectively overcomes off-line secondary heating stove heat or individually matches offline
It sets and mends warm device or Configuration Online mends the disadvantage that warm device mends breakdown bar temperature, realize stringent to hot processing temperature requirement
The rolling of DC53 mould steel strip plates carries out online temperature-compensating, to ensure that DC53 molds steel ingot is best at 1180 ± 25 DEG C
Pyroplastic deformation area rolls, and controls the quality of edges of steel billet, avoids side and splits and chink, ensure that the abundant of eutectic carbide
Broken and homogenization.Meanwhile the utility model arrangement takes full advantage of rolled piece waste heat, and it is online to mend temperature, it significantly reduces and is produced into
This.
Description of the drawings：
Fig. 1 is the online temperature-compensating technology arrangement schematic diagram of the utility model.
In figure：Pusher 1, heating furnace 2, push away rod iron group 2a, transfer roller groups 3, rolling transfer roller 3a, melt down transfer roller 3b,
