Abstract
本实用新型属于冶金领域，具体涉及电弧炉水冷挂渣炉壁结构，它包括钢板及安装在钢板上的冷却水管，其特征是冷却水管的外壁上固定安装有横截面呈梯形的钢板，钢板的小面与冷却水管连接，钢板与冷却水管的轴线平行，钢板、冷却水管之间的空间通过耐火材料填塞。横截面呈梯形的钢板使填充的耐火材料形成内大外小的楔型结构，耐火材料形成难以脱落保护层，耐火材料的保护不仅增强了水冷管对钢板的降温作用，而且阻挡了弧光和废钢直接接触水冷钢管，避免了钢管因热应力不均匀造成裂纹，导致漏水的现象。从而将水冷设备的使用寿命提高了两倍。
The utility model belongs to the field of metallurgy, and in particular relates to a water-cooled slag-hanging furnace wall structure of an electric arc furnace. The small face is connected with the cooling water pipe, the steel plate is parallel to the axis of the cooling water pipe, and the space between the steel plate and the cooling water pipe is filled with a refractory material. The steel plate with trapezoidal cross-section makes the filled refractory material form a wedge-shaped structure with a large inside and a small outside. The refractory material forms a protective layer that is difficult to fall off. The protection of the refractory material not only enhances the cooling effect of the water-cooled tube on the steel plate, but also blocks arc light and scrap steel Direct contact with the water-cooled steel pipe avoids the phenomenon of water leakage caused by cracks in the steel pipe due to uneven thermal stress. Thus, the service life of the water-cooling equipment is doubled.
Description
Technical field
The utility model belongs to field of metallurgy, is specifically related to electric arc furnaces water-cooled dross protecting wall structure.
Background technology
Electric arc furnaces water-cooled dross protecting wall structure ecto-entad is by steel plate and be installed in cooling water pipe on the steel plate, the I that is distributed in the water cooling tube inboard, V, Y shape slag nail and filler and constitute; in the stainless steel electric arc furnaces; reason owing to process conditions; very fast being burnt of slag nail; make the furnace wall can not form effective dross protective layer; cause that the furnace wall is subjected to that high arc temperature direct baking, arc through, molten steel splash etc., the water cooling tube leakage accident often takes place.
Summary of the invention
The utility model provides electric arc furnaces water-cooled dross protecting wall structure, avoids taking place the water cooling equipment leakage accident.
The utility model comprises steel plate and is installed in cooling water pipe on the steel plate, it is characterized in that being installed with cross section on the outer wall of cooling water pipe inboard is trapezoidal steel plate, the facet of steel plate is connected with cooling water pipe, steel plate is parallel with the axis of cooling water pipe, and clog by refractory material in the space between steel plate, the cooling water pipe.
Cross section be refractory material that trapezoidal steel plate makes filling form in big outer little taper structure; refractory material forms and is difficult to the protective layer that comes off; the protection of refractory material has not only strengthened the cooling effect of water cooling tube to steel plate; and arc light and the cold steel pipe of steel scrap direct contact water have been stopped; avoided steel pipe to cause crackle, caused the phenomenon of leaking because of thermal stress is inhomogeneous.Thereby twice will have been improved the service life of water cooling equipment.
Description of drawings
Fig. 1 is the structure chart of the utility model embodiment.
Among the figure: 1, refractory material, 2, steel plate, 3, cooling water pipe, 4, steel plate.
The specific embodiment
