Description

电阻炉
技术领域
本申请涉及电阻炉设计技术领域,更具体地说,涉及一种电阻炉。
背景技术
现有技术中的电阻炉,参考图1,其使用碳化硅铝板3防止氧化皮1掉落至电阻带2,由于碳化硅铝板3受热易碎,并且炉体内工件受热会掉落氧化皮1,由于电阻带2设置于炉体底部,碳化硅铝板3碎片和工件掉落的氧化皮1均掉落在电阻带2上,与其直接接触,电阻带2容易损坏,导致电阻炉经常需要维修。其中,氧化皮1的影响尤其严重。
另外,碳化硅铝板3的存在,隔离了电阻带2,严重降低了电阻带2发热的利用效率,浪费大量电能。
因此,如何实现在不使用碳化硅铝板的情况下避免氧化皮与电阻带接触,是目前本领域技术人员亟待解决的问题。
发明内容
有鉴于此,本申请提供了一种电阻炉,以实现在不使用碳化硅铝板的情况下避免氧化皮与电阻带接触。
为了达到上述目的,本申请提供如下技术方案:
一种电阻炉,包括炉体和设置于炉体底部的耐高温的电阻带支架,电阻带支架为用于支撑电阻带的、顶部为设置有向下斜坡的尖端顶部,炉体底部区域的电阻带设置于电阻带支架的顶部上。
优选的,电阻带支架设置于炉体内的托盘的两侧位置,炉体底部区域的电阻带与电阻带支架对应,设置于托盘的两侧。
优选的,电阻带支架包括多根耐火砖条,多根耐火砖条平行设置于炉体底部。
优选的,耐火砖条的顶部支撑有水平设置电阻带,耐火砖的顶部的两侧设置有向下方向的斜坡,其两侧斜坡面与其支撑的所述电阻带的平面夹角均为45度至65度。
优选的,耐火砖的顶部还设置有圆角。
优选的,炉体内的两侧壁上设置有电阻带。
本申请所提供的一种电阻炉,包括炉体和设置于炉体底部的耐高温的电阻带支架,电阻带支架为用于支撑电阻带的、顶部为设置有向下斜坡的尖端顶部,炉体底部区域的电阻带设置于电阻带支架的顶部上。在炉体内,由于使用电阻带支架将炉体底部的电阻带支撑起,使其架离底面,并且电阻带支架顶部比较尖,设置有向下的斜坡,氧化皮掉落时候只有较少会在电阻带支架上停留,大部分会顺着斜坡下落到预定位置,这样避免了电阻带与氧化皮接触,进而减少了维修频数。
附图说明
为了更清楚地说明本申请实施例或现有技术中的技术方案,下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍,显而易见地,下面描述中的附图仅仅是本申请的一些实施例,对于本领域普通技术人员来讲,在不付出创造性劳动的前提下,还可以根据这些附图获得其他的附图。

图2为本申请所提供的电阻炉的结构示意图;
图3为本申请所提供的电阻炉的电阻带支架与电阻带装配结构俯视图;
图4为本申请所提供的电阻炉的电阻带支架与电阻带装配结构侧视图;
上图中:1为氧化皮、2为电阻带、3为碳化硅铝板、4为炉体、5为提升轮、6为炉门、7为电阻带、8为电阻带、9为托盘、10为电阻带支架。
具体实施方式
本申请提供了一种电阻炉,实现了在不使用碳化硅铝板的情况下避免氧化皮与电阻带接触。
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整的描述,显然,所描述的实施例仅仅是本申请一部分实施例,而不是全部的实施例。基于本申请的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
图2为本申请所提供的电阻炉的结构示意图;图3为本申请所提供的电阻炉的电阻带支架与电阻带装配结构俯视图;图4为本申请所提供的电阻炉的电阻带支架与电阻带装配结构侧视图。
本申请提供的电阻炉,包括炉体4和设置于炉体4底部的耐高温的电阻带支架10,电阻带支架10为用于支撑电阻带8的、顶部为设置有向下斜坡的尖端顶部,炉体4底部区域的电阻带8设置于电阻带支架10的顶部上。在炉体4内,由于使用电阻带支架10将炉体4底部的电阻带8支撑起,使其架离底面,并且电阻带支架10顶部比较尖,设置有向下的斜坡,氧化皮掉落时候只有较少会在电阻带支架10上停留,大部分会顺着斜坡下落到预定位置,这样避免了电阻带8与氧化皮接触,进而减少维修次数。另外,需要说明的是,本发明取消了现有技术中的碳化硅铝板,避免其脆裂掉碎片导致电阻带8损坏,节省碳化硅铝板的费用,并且更重要的是,取消碳化硅铝板后,没有阻挡物隔离电阻带8与工件,这样,电阻带8散发的热辐射可以在炉体4内形成旋涡热场,加热效率比原来被碳化硅铝板隔离开后形成的热场高很多,现有技术实现起炉时间达到2.5小时,使用了本方案的技术,起炉时间只需要90分钟,增加了效率,并且节省大量电能,经济效益非常高。
本装置中,提升轮5用于提升炉门6,实现对其开启关闭。
在本申请一具体实施例中,电阻带支架10设置于炉体4内的托盘9的两侧位置,炉体4底部区域的电阻带8与电阻带支架10对应,设置于托盘9的两侧。托盘9是用于放置工件的支撑件,电阻带支架10设置于托盘9两侧,能够减少氧化皮掉到电阻带8上,减少其损坏。并且,采用这种设计,三区、四区接近不加热,还能节省电能。
在本申请一具体实施例中,电阻带支架10包括多根耐火砖条,多根耐火砖条平行设置于炉体4底部。多根耐火砖条曾矩阵状排列,均匀分布设置于电阻带8之下。实现将电阻带8架离底面,减少与氧化皮接触。改进后,炉温升高速度加快,一区起炉90分钟,而改进前需要2.5小时。改进后氧化皮脱落预想的位置。电阻带损坏率降低,实现节省电阻带,并且降低维修频次。提高连续调质生产节拍。
在本申请一具体实施例中,耐火砖条的顶部支撑有水平设置电阻带8,耐火砖的顶部的两侧设置有向下方向的斜坡,其两侧斜坡面与其支撑的电阻带8的平面夹角均为45度至65度。该斜坡用于引导氧化皮等碎屑按照斜坡的角度掉落到炉体4底面。经过反复试验,该角度设置为60度最佳。
在本申请一具体实施例中,耐火砖的顶部还设置有圆角。该圆角与电阻带8直接抵靠,用于对其支撑,设置圆角减少对其接触面磨损,圆角为R5圆角。
在本申请一具体实施例中,炉体4内的两侧壁上设置有电阻带7。炉体4两侧壁设置电阻带7,增加加热效率,并且两侧壁的电阻带7不存在与氧化皮接触的问题。
本说明书中各个实施例采用递进的方式描述,每个实施例重点说明的都是与其他实施例的不同之处,各个实施例之间相同相似部分互相参见即可。
对所公开的实施例的上述说明,使本领域专业技术人员能够实现或使用本申请。对这些实施例的多种修改对本领域的专业技术人员来说将是显而易见的,本文中所定义的一般原理可以在不脱离本申请的精神或范围的情况下,在其它实施例中实现。因此,本申请将不会被限制于本文所示的这些实施例,而是要符合与本文所公开的原理和新颖特点相一致的最宽的范围。
