Abstract
The invention discloses a novel steel ladle cover and a production technology. The novel steel ladle cover is characterized by comprising a barrel-shaped ladle cover outer shell with the lower end open, six reinforcing ribs are arranged at the upper end of the ladle cover outer shell, hanging rings are welded on the reinforcing ribs, mushroom nails with points upward are welded on the inner wall of the upper bottom of the ladle cover outer shell, and filling is filled in a residual space of the ladle outer shell, wherein filling comprises the following components by mass ratio of glass water: light corundum material=9:1. The two difficult problems that safety problems are caused due to unstable ladle structure and fireproofing material is prone to falling off due to the fact that an inner structure of the ladle cover is not tight are solved.
Description
technical field [0001] The invention relates to a novel ladle cover and a production process. Background technique [0002] Recently, the ladle cover used is a supporting steel shell welded by steel plates, and the inner structure of the cover is knotted with refractory materials. Not only is the ladle cover not firm, unsafe, short in service life, and frequently replaced, but also the refractory material cracks gradually fall off due to the loose structure during use, resulting in a decrease in the thermal insulation performance of the ladle cover and an increase in the temperature drop of the molten steel in the ladle. Large, at the same time falling off refractory materials and non-metallic elements in molten steel react with each other to produce non-metallic inclusions that cause secondary pollution to molten steel and adversely affect the quality of steel. [0003] So far, there are no public reports on the new technology and implementation device for making ladle lid...
