附录3附录3美国5829117号专利热锯机锯切式连续轧制方法及它的装置美国专利局发布于1998年11月3日有效期至2017年1月30日摘要一种热锯锯切与连续轧制方法使得可以连续同时铸造两根钢坯，能用热锯机将钢坯切成预定的长度，能通过一连接装置直接提供由轧制线生产的钢坯，能用以闪光对焊机不断地将钢坯焊接成一连续的钢坯，能用磨床将钢坯焊缝处的毛刺去除，用感应加热器将钢坯加热到一更高温度后可以通过一轧机群连续轧制钢坯。一种热锯锯切与连续轧制的装置可以提供以上所描述的加工方法。专利权项专利权项有1、一种热锯锯切与连续轧制方法由以下几步构成连续同时铸造连根钢坯；用热锯机将钢坯切成预定长度；通过一连接装置提供由轧制线生产的钢坯；用以闪光对焊机不断地将钢坯焊成一连续的钢坯；用磨床将钢坯焊缝处的毛刺去除；用感应加热器将钢坯加热到更高温度并通过一轧机群连续轧制钢坯。2、一种热锯锯切与连续轧制装置构成如下一能同时铸造两根钢坯的铸造机器；一安装在铸造线上的移动热锯机；一连接装置，安装在铸造线与轧制线直接，能交替传送从切割处获得的钢坯部件；一移动式闪光对焊机，安装在连接装置的出口，能将钢坯部件不断的焊成一连续的钢坯；一移动式磨床，安装在移动式闪光对焊机的出口，能去除钢坯焊缝处的毛刺；一感应加热器，安装在移动式磨床的出口，能将连续的钢坯加热到一更高温度；一轧机群组，用于轧制被加热到上述更高温度的钢坯。3、权项2中的连接装置构成如下一链式传送机，安装在轧机线的一侧，将铸造线提供的钢坯送到轧制线；另一链式传送机，安装在轧制线的另一侧，将另一条铸造线的钢坯传送到轧制线。4、一种热锯锯切与连续轧制装置构成如下一能同时铸造两根钢坯的铸造机器；一安装在铸造线上的移动热锯机；一连接装置，安装在铸造线与轧制线之间，能通过转动到预定角度交替传送从切割处获得的钢坯部件；一移动式闪光对焊机，安装在连接装置的出口，能将钢坯部件不断地焊成一连续的钢坯；一移动式磨床，安装在移动式闪光对焊机的出口，能去除钢坯焊缝处的毛刺；一感应加热器，安装在移动式磨床的出口，能将连续的钢坯加热到一更高温度；一轧机群组，用于轧制被加热到上述更高温度的钢坯。5、权项4中的连接装置构成如下一能往复运动到一预定角度的转盘，可以将钢坯部件由一转盘传送到另一转盘的回转中心线上。综述附录3发明的背景1、发明的领域本发明是关于一种连续的轧制方法，轧制的钢坯由一连续的铸造机提供。尤其重要的是，本发明是关于一种连续的轧制方法和装置。在这种装置中，可以直接提供两根钢坯并由热锯机锯切。锯切的钢坯用闪光对焊机焊接在一起，并磨削去毛刺。之后生成的钢坯被感应加热到更高温度后进行轧制。2、涉及的技术钢坯连轧法是一种有效的节能轧制方法。它可以生产盘条、钢棒和型钢。例如，日本未经审查的专利出版物第5243754号提出的钢坯连轧法中，钢坯由一连续铸造机提供，而后钢坯被热锯机切成预定长度，切断后经暂时冷却钢坯部件被加热炉重新加热，然后被重新加热的钢坯部件用闪光对焊机焊接在一起，毛刺被钢坯烧剥器上的成型刀具去除。之后连续的钢坯被感应加热器加热到轧制所需的温度从而使得加热的连续的钢坯由轧机群组轧制。然而在这种常规的连轧法中，钢坯必须由室温20加热到1000左右，以达到轧制所需的最终温度1020。因此增加了很多加热的成本。另外，连续铸造能力和连续轧制能力的不同阻碍了钢坯铸造线和轧制线的直接连接。这就不可避免的导致了需使用巨大的设备并占用很大的空间。更重要的是，成型刀具被用来去除钢坯闪光对焊部分的毛刺。这就使得当钢坯被焊接好后成型刀具的寿命短而不能连续的工作。从而使得在这个例子中难以完成去除毛刺的工作。这项发明的摘要这项发明的目的是解决上述的问题并提供一种连续轧制的方法和它的装置。从而使得进一步节约能源和空间并获得更高的效率成为可能。这项发明的热锯连轧法由以下几步构成连续地铸造两根钢坯；用热锯机将钢坯锯成预定长度；通过连接装置将锯切的钢坯直接传送到轧制线；用闪光对焊机连续地焊接钢坯部件；用磨床磨削去除焊接钢坯的毛刺；用感应加热器将连续的钢坯加热到更高温度；通过轧机群组连续地轧制钢坯。首先，热锯连轧装置包括一能连续同时铸造两根钢坯的铸造机；安装在各自铸造线上的移动式热锯机；安装在铸造线与轧制线之间的连接装置，它能交替传送锯切处的钢坯；安装在传送装置出口的移动式闪光对焊机，它能将钢坯部件不断地焊成连续的钢坯；安装在移动式闪光对焊机出口的移动式磨床，它能去除连续钢坯焊缝处的毛刺；安装在移动式磨床出口处的感应加热器，它能将连续的钢坯加热到一更高温度；一轧机群组，它能轧制被加热到上述更高温度的连续钢坯。其次，热锯连轧装置包括一能连续同时铸造两根钢坯的铸造机；安装在各自铸造线上的移动式热锯机；安装在铸造线与轧制线之间的连接装置，它能转到预定角度从而可交替传送锯切的钢坯；安装在传送装置出口的移动式闪光对焊机，它能将钢坯部件不断地焊成连续的钢坯；安装在移动式闪光对焊机出口的移动式磨床，它能去除连续钢坯焊缝处的毛刺；安装在移动式磨床出口处的感应加热器，它能将连续的钢坯加热到一更高温度；一轧机群组，它能轧制被加热到上述更高温度的连续钢坯。通过本发明，钢坯铸造线和轧制线被一连接装置间歇的连接在一起，从而消除了使用加热炉的需要。而加热炉在常规方法中很常见。这就使得加热得到有效利用。因为感应加热器只需将钢坯从100加热到920以及在铸造机输出端将钢坯加热到轧制温度1020,因此加热成本得到很大幅度的减少。因为当连铸线只有一条时很难平衡连铸能力和连轧能力，因此将连铸线数目提高到两根。将两条连铸线和一条连轧线通过一传送装置连接在一起时一种有效地方式，它平衡了连铸能力和连轧能力。另外，当连铸线有3根或更多时，一干扰铸造线上的热锯机的热锯机就不能放置了。另外，因为热锯机的使用，使得切断面平整有规则，从而减少了闪光对焊机的焊接时间。磨床被用来去除焊缝处的毛刺，从而使得刀具寿命长，即使形成的一个步骤是在焊接部分也能完成去除毛刺的工作。综上所述，钢坯铸造线和轧制线由一连接装置间歇的连接在一起，从附录3而避免了加热炉的使用，进而有效的节约了能源和降低了加热成本。另外，由于两条铸造线的使用，连接装置得以有效平衡了连铸能力和连轧能力。这使得与常规设备相比节约了空间。再次，由于减少了闪光对焊的时间，从而延长了磨床的寿命，满足了连轧的要求。USPATENT5829117HOTSAWCUTTINGTYPECONTINUOUSROLLINGMETHODANDAPPARATUSTHEREOFUSPATENTISSUEDONNOVEMBER3,1998ESTIMATEDPATENTEXPIRATIONDATEJANUARY30,2017ABSTRACTAHOTSAWCUTTINGTYPECONTINUOUSROLLINGMETHODCOMPRISESCASTINGTWOSTRANDBILLETSCONTINUOUSLYCUTTINGTHEBILLETSTOPREDETERMINEDLENGTHBYHOTSAWSDIRECTLYFEEDINGBILLETPORTIONSOBTAINEDBYCUTTINGONTOAROLLINGLINEVIAALINECONNECTINGDEVICECONTINUOUSLYWELDINGANDJOININGTHEBILLETSPORTIONSBYAFLASHBUTTWELDERTOFORMACONTINUOUSBILLETGRINDINGANDREMOVINGBURRSATTHEWELDEDPORTIONOFTHECONTINUOUSBILLETBYAGRINDINGMACHINEANDCONTINUOUSLYROLLINGTHEBILLETBYAROLLINGMILLGROUP,AFTERHEATINGTHECONTINUOUSBILLETTOAHIGHERTEMPERATUREBYANINDUCTIONHEATERAHOTSAWCUTTINGTYPECONTINUOUSROLLINGAPPARATUSISPROVIDEDFORPERFORMINGTHEABOVEDESCRIBEDMETHODCLAIMSWHATISCLAIMEDIS1AHOTSAWCUTTINGTYPECONTINUOUSROLLINGMETHODCOMPRISINGTHESTEPSOFCASTINGTWOSTRANDBILLETSCONTINOUSLYCUTTINGTHEBILLETSTOPREDETERMINEDLENGTHBYHOTSAWSDIRECTLYFEEDINGBILLETPORTIONSOBTAINEDBYCUTTINGTOABILLETROLLINGLINETHROUGHMEANSOFALINECONNECTINGDEVICECONTINOUSLYWELDINGANDJOININGTHEBILLETSPORTIONSBYAFLASHBUTTWELDERTOFORMACONTINUOUSBILLETGRINDINGANDREMOVINGBURRSATTHEWELDEDBILLETPORTIONBYAGRINDINGMACHINEHEATINGTHECONTINUOUSBILLETTOAHIGHERTEMPERATUREBYANINDUCTIONHEATERANDCONTINUOUSLYROLLINGTHEBILLETBYAROLLINGMILLGROUP2AHOTSAWCUTTINGTYPECONTINUOUSROLLINGAPPARATUSCOMPRISINGACONTINUOUSCASTINGMACHINEFORCASTINGTWOSTRANDBILLETSTRAVELINGTYPEHOTSAWSDISPOSEDONTHEIRRESPECTIVECASTINGLINESALINECONNECTINGDEVICEINCLUDINGMEANSFORALTERNATELYPERFORMINGTRANSVERSEFEEDINGOFBILLETPORTIONSOBTAINEDBYCUTTING,DISPOSEDBETWEENTHECASTINGLINESANDAROLLINGLINEA附录3TRAVELINGTYPEFLASHBUTTWELDERFORCONTINUOUSLYWELDINGANDJOININGTHEBILLETPORTIONSTOFORMACONTINUOUSBILLET,DISPOSEDATADOWNSTREAMSIDEOFTHELINECONNECTINGDEVICEATRAVELINGTYPEGRINDINGMACHINEFORREMOVINGBURRSATTHEWELDEDPORTIONOFTHECONTINUOUSBILLET,DISPOSEDATADOWNSTREAMSIDEOFTHETRAVELINGTYPEFLASHBUTTWELDERANINDUCTIONHEATERFORHEATINGTHECONTINUOUSBILLETTOAHIGHERTEMPERATURE,DISPOSEDATADOWNSTREAMSIDEOFTHETRAVELINGTYPEGRINDINGMACHINEANDAROLLINGMILLGROUPFORROLLINGTHECONTINUOUSBILLETWHICHWASHEATEDTOSAIDHIGHERTEMPERATURE3THEAPPARATUSOFCLAIM2,WHEREINTHELINECONNECTINGDEVICECOMPRISESAFIRSTCHAINCONVEYORDISPOSEDATONESIDEOFTHEROLLINGLINE,TRANSVERSELYFEEDINGTHEBILLETONONECASTINGLINEONTOTHEROLLINGLINEANDASECONDCHAINCONVEYORDISPOSEDATANOTHERSIDEOFTHEROLLINGLINE,TRANSVERSELYFE
