The invention belongs to the technical field of metallurgical equipment, in particular to a ladle refining furnace water-cooling furnace cover, which comprises a furnace cover body; a smoke collecting hood is fixedly connected above the furnace cover body; a dust removing flue is arranged on the side wall of the smoke collecting hood; the lower end of the furnace cover body is opened and fixedly connected with a furnace mask skirt; the furnace cover body is in the shape of a dome. The furnace cover only includes a dedusting flue connected to the side wall of the smoke collecting hood. The side wall of the smoke collecting cover adopts an octagonal structure. The furnace cover is made of water-cooled tubes of medium pressure boilers with various diameters, and all reserved holes for water-cooled tubes are arranged on the main water inlet pipe. On the basis of almost no new accessories, the invention not only reduces the slag sticking probability of the furnace cover body, but also cancels the package mouth flue, and reduces the burden and danger of the lifting mechanism of the furnace cover; in addition, the cooling effect of the furnace cover is better, which is convenient for maintenance and replacement, and the cost and labor intensity of the workers are significantly reduced.

一种钢包精炼炉水冷炉盖
本专利技术属于冶金设备
,尤其涉及一种钢包精炼炉水冷炉盖。
技术介绍
钢包精炼炉是钢液精炼的主要设备之一,水冷炉盖是钢包精炼炉的主要构成部分,钢水精炼工序的效果,很大程度取决于盖内的冶炼气氛控制。目前广泛应用的钢包精炼炉炉盖多采用等径密排钢管形式,解决了早期的钢板焊接形式,循环阻力大,内侧焊缝无法焊接,经常漏水的问题;但是由于该种炉盖的炉盖本体及炉口裙罩采用双叠“ㄇ”字型,因此在高节奏冶炼以及冶炼操作方式的更新变化下,该结构的不足之处也就不断显现,诸如炉盖内壁特别是拐角处粘渣问题非常严重且清渣困难,一旦清理操作不当造成换热管漏水,需占用长时间修补而影响生产;一旦不及时清理,炉盖上粘接的大量炉渣可以达到上百公斤,这使炉盖自重大大加重,对炉盖升降机构又增加负担和危险,更重要的是保证不了冶炼气氛,从而影响钢水精炼的效果。
技术实现思路
针对现有技术的缺陷,本专利技术提供一种能够有效减轻粘渣的钢包精炼炉水冷炉盖。为了实现上述目的,本专利技术所采用的具体技术方案为:一种钢包精炼炉水冷炉盖,该水冷炉盖包括炉盖本体;炉盖本体上方固定连接有集烟罩;集烟罩侧壁设有除尘烟道;所述炉盖本体的下端开口并固定连接有炉口罩裙;所述炉盖本体为穹窿形。进一步,该炉盖仅包括一处连接在集烟罩侧壁上的除尘烟道。进一步,所述除尘烟道为水冷烟道。进一步,所述集烟罩侧壁采用八字形结构。进一步,该炉盖由多种管径的中压锅炉水冷管盘制成型,每套水冷管包括冷水进水和热水回水过程;各套水冷管的进水由连接总进水管的配水管供应,各套水冷管内的水被炉盖加热后汇集到受热管,并最终由连接受热管 ...
