The utility model discloses a slag tank for avoiding stress cracks, which belongs to the field of slag tanks. Including slag tank body, lifting lug and tank turning seat, also including a movable joint mechanism, the movable joint mechanism includes clamping plate and supporting rib plate, the clamping plate is fixed below the lifting lug; one end of the supporting rib plate is fixed on the tank turning seat, the other end is clamped in the clamping plate, the clamping plate is composed of two triangular steel plates of the same shape, which are arranged axially symmetrically under the lifting lug, and the hollow space which can be inserted into the supporting rib plate is left in the middle. Clearance, the support rib plate is clamped between one side of the clamping plate and the lifting lug, leaving a gap of 3-8 mm. The clamping plate and the support rib plate are welded at the corresponding position with bilateral K-shaped grooves. The protective cover is divided into inner cover and outer cover. The inner cover is fixed on the support rib plate, and the outer cover is fixed on the clamping plate, nested but not contacted with each other. The utility model has the advantages of simple structure and convenient production, and uses the movable joint mechanism as auxiliary support, which solves the problem that stress cracks easily occur at the auxiliary support of the traditional slag tank and extend to the body of the slag tank.

一种避免应力裂纹的渣罐
本技术涉及渣罐领域,更具体地说是涉及一种避免应力裂纹的渣罐。
技术介绍
渣罐是冶金行业中重要的设备,用于盛装钢铁冶炼过程中产生的高温熔渣,目前冶金工业上渣罐在倾翻渣物时,都在渣罐本体外侧增设了辅助支撑,并在渣罐制造时,一同铸成整体,便于倾翻装置的夹持,辅助倾翻工作的完成。由于渣罐实际工况条件非常恶劣,尤其要频繁的直接接触1100℃以上高温渣物及不断空冷,热胀冷缩非常频繁,甚至一个月不到,就在渣罐辅助支撑处出现严重应力裂纹,有的以辅助支撑为中心,裂纹延伸到渣罐本体上,甚至贯穿,造成渣罐报废。生产中,不管怎样增大辅助支撑强度及罐壳厚度,都无法克服严重裂纹现象,严重影响冶金生产安全的顺利进行。中国专利公开号:CN101368220B,公开日2010年8月11日,公开了一种冶金渣罐及其制造方法,所述冶金渣罐在罐体焊接阶段,在冶金渣罐口耳轴侧倾翻受力部采用“十字架”加强钢筋板结构,即在罐体耳轴两侧各焊接一块纵向长筋板与一块横向长筋板,形成状如“十字”形结构。该十字加强钢筋板结构虽然能对倾翻渣罐起到很好的辅助支撑效果,但是随着渣罐的使用,其热胀冷缩产生 ...
