The utility model discloses a slag iron groove cover plate, including steel plate shell, durable wood, anchorage nail and tendons. The steel plate shell is a channel steel structure buckled on the slag iron groove, and the two sides leg plates of the channel steel are opened to the two sides to form a blunt angle on both sides; the anchorage nail and the stiffener are fixed on the inner wall of the steel plate shell, and at the same time, the steel plate is resistant to the steel plate. The material is also coated on the inner wall of the shell of the steel plate, covering the anchor pin and the rib plate, and the steel plate shell is provided with an operation door inside and outside the communicating groove. The advantages are as follows: first, the steel plate shell is set into a trapezoid arch structure, which not only increases the overall structural strength, but also reduces the slag iron spatter and radiation damage to the cover plate by increasing the distance between the inside of the cover plate and the slag iron liquid surface. Secondly, the structure strength of the T shaped steel plate and the steel shell is formed, and the structure strength is improved; and then, the structure strength of the steel plate is improved. The operation door makes the operation in front of the furnace more convenient without lifting the cover plate.

一种渣铁沟盖板
本技术涉及炼铁
,尤其涉及一种渣铁沟盖板。
技术介绍
高炉出铁场炉前是炼铁劳动最密集区域,而且此区域温度高,烟尘量大,为高炉出铁及渣铁分离作业区域。区域内渣铁沟多采用盖板覆盖,防止渣铁喷溅及烟尘扩散,形式多为;平直盖板和弧形盖板。现有平板盖板使用时离熔渣和铁水液面距离小,存在容易变形,寿命短,耐材易脱落等缺点,特别在渣铁喷溅时直接容易损坏。弧形盖板上无法制作大型操作门,且门容易变形漏烟,体积质量大,不易吊装。
技术实现思路
技术目的:本技术的目的是提供一种渣铁沟盖板,该盖板强度和耐热性得到提高,且方便炉前操作,减少劳动强度,改善炉前环境。技术方案:本技术的渣铁沟盖板,包括钢板外壳、耐材、锚固钉、筋板;所述钢板外壳为扣在渣铁沟上的槽钢结构,该槽钢的两侧腿板往两侧张开与腰板形成钝角,即形成横截面为梯形的拱形结构,增强了整体结构强度,增大了盖板内壁与渣铁液面的距离,减少了渣铁喷溅及辐射热对盖板的损害,同时该结构容纳烟尘空间增大,有利于改善炉前环境;所述锚固钉和筋板间隔固定在钢板外壳的槽内壁,同时,耐材也涂覆于钢板外壳的槽内壁,并覆盖锚固钉与筋板,相比平直盖板,在拱形钢板外壳内壁涂覆耐材,可减小水平顶板下耐材面积,可有效防止耐材脱落;所述钢板外壳上设有连通槽内外的操作门。该操作门设置在需要操作的位置(如渣铁沟分岔口、渣铁分离处、观察采样处)可直接开门操作,不需要吊走沟盖,减少炉前劳动强度。进一步的,所述筋板为一侧与钢板外壳固定形成工字截面为的T形筋板,现有技术多用条形筋板,采用T形筋板和钢板外壳形成的工字钢结构既增加了强度,防止变形,又可防止耐材的脱 ...
