Description
技术领域 technical field
本发明涉及一种工业炉窑的金属梁结构,尤其涉及一种冶金行业钢管步进炉炉内的多孔金属梁。The invention relates to a metal beam structure of an industrial furnace, in particular to a porous metal beam in a steel pipe walking furnace in the metallurgical industry.
背景技术 Background technique
目前,在钢管步进炉中,炉内钢管需要通过金属固定梁和金属活动梁来支撑坯料,活动梁循环运动一次,坯料则前进一个步距。固定梁和活动梁都为耐热钢金属梁构件,根据不同的工况制造成不同的形状。请参考图1,为现有的工业炉窑金属梁的结构示意图。如图1所示,现有的工业炉窑金属梁包括梁主体101,梁主体101上表面具有连续设置的多个内凹弧形支撑面102,多个钢管103分别置于各个内凹弧形支撑面102上。由于钢管103的步距与梁主体101上相邻的两内凹弧形支撑面102之间的齿距不一致,使钢管103每前进一个步距均能转动一定的角度,避免钢管103在高温状态下弯曲。At present, in the steel pipe walking furnace, the steel pipe in the furnace needs to support the billet through metal fixed beams and metal movable beams. The movable beam moves once in a cycle, and the billet advances by one step. Both the fixed beam and the movable beam are heat-resistant steel metal beam components, which are manufactured into different shapes according to different working conditions. Please refer to FIG. 1 , which is a structural schematic diagram of an existing industrial furnace metal beam. As shown in Figure 1, the existing metal beams of industrial furnaces include a beam
众所周知,钢管103在加热的过程中不可避免会产生氧化铁皮,氧化铁皮脱落在内凹弧形支撑面102上,随着脱落的氧化铁皮越积越高,会阻碍钢管正常滚动,这样不但会使钢管发生弯曲,还存在不能正常出料的隐患。另外,氧化铁皮也有可能与钢管粘连,破坏钢管表面质量。如采用人工作业清除脱落的氧化铁皮,不但费时费力,而且会影响正常生产。因此如何及时清除氧化铁皮,保证正常生产不受影响已成为业界亟需改进的目标。As we all know, the
有鉴于金属梁表面氧化铁皮堆积的问题,本设计人基于从事机械设计制造多年的丰富经验及过强的专业知识,结合金属梁的应用实际,积极加以研究创新,以期在结构方面克服现有金属梁的缺点。In view of the problem of iron scale accumulation on the surface of metal beams, based on the rich experience and strong professional knowledge in mechanical design and manufacturing for many years, combined with the actual application of metal beams, the designer actively researched and innovated, in order to overcome the existing metal beams in terms of structure. Beam's downside.
