Abstract
The invention relates to a drainage agent for the automatic steel-pouring of a ladle in a smelting process, which is used in the smelting process in metallurgy industry and capable of improving steel quality and yield and reducing product cost, and is characterized in that the raw material of the drainage agent is prepared by mixing and stirring 50 percent of silica, 20 percent of forsterite, 5 percent of active carbon and 20 percent of chromium ore uniformly. With drainage agent for the automatic steel-pouring of a ladle in the smelting process, a smelting ladle can freely open and avoid rising steel, staggering steel, and accidents such as burning operators. The free-opening rate of the ladle reaches more than 98 percent, and the free-opening success rate of the ladle reaches 100 percent. The drainage agent improves steel quality and yield, reduces product cost, and reduces the labor intensity of workers.
Description
Technical field
The present invention relates to a kind of metallurgy industry smelting process that is used for, the smelting process that can improve the quality of steel and output and reduce product cost is used for the drainage agent of automatic steel-pouring of ladle.
Background technology
At present, the traditional method of domestic metallurgy industry smelting process steel ladle casting is to burn the oxygen drainage, and this method exists: need a large amount of oxygen and steel pipe with burning the drainage of oxygen pipe burning oxygen, cause very big waste; When drainage because of burn oxygen often, the time is long, easily form iron oxide stop up in column jecket, and steel is emitted in formation, the steel of staggering, and causes the economic loss of scrapping and can't save, casting rate is low.At present, the drainage material that adopts in actual production is river sand, sea sand etc., and this material contains silica generally more than 90%, and its fusing point height is easy to add in the assorted Dao Gang Ingot, influences the quality of stocking.Adopt siliceous drainage agent in addition, its fusing point is about 1670 ℃, by melting with the molten steel contact-making surface after the refining, the melting layer that forms is thicker, after open at the mobile mouth of a river during steel ladle casting, the internal pressure of molten steel is less than siliceous drainage agent, and the pressure that melting layer bears can't be washed melting layer open, can not directly inject conticaster and cause the casting failure.
Summary of the invention
The present invention has overcome the defective of above-mentioned existence, and purpose is for quality that improves steel and output and product cost, the drainage agent that provides a kind of smelting process to be used for automatic steel-pouring of ladle are provided.
Smelting process of the present invention is used for the drainage agent content Description of automatic steel-pouring of ladle:
Smelting process of the present invention is used for the drainage agent of automatic steel-pouring of ladle, it is characterized in that: its raw material is by silica 50%, forsterite 20%, graphite 5%, activated carbon 5%, chrome ore 20%, and mixing and stirring is formulated.
The drainage agent that smelting process of the present invention is used for automatic steel-pouring of ladle can automatic casting when smelting steel ladle casting, can avoid steel occurring emitting, the accidents such as steel and operating personnel's burn of staggering.Automatic casting ratio can reach more than 98%, opens to water success rate and can reach 100%.Improve the quality and the output of steel, reduced product cost, also alleviated working strength of workers.
The specific embodiment
Do below the drainage agent that smelting process of the present invention is used for automatic steel-pouring of ladle is achieved in that and specify.The invention smelting process is used for the drainage agent of automatic steel-pouring of ladle, and its raw material is by percentage system by weight, and by silica 50%, forsterite 20%, graphite 5%, activated carbon 5%, chrome ore 20%, mixing and stirring is formulated.The drainage agent that smelting process is used for automatic steel-pouring of ladle when smelting directly joins the place, the mobile mouth of a river of molten steel jar, the molten steel jar fills with to enter behind the molten steel and carries out refining, continuous casting in the refining furnace, to be used for the melting layer that the drainage agent of automatic steel-pouring of ladle and molten steel contact-making surface form thinner for smelting process in this process, when casting, open the mobile mouth of a river of molten steel jar, the drainage agent flows down automatically from the mouth of a river, and molten steel breaks through melting layer and directly is injected into and finishes once casting in the conticaster.Through test, automatic casting ratio can reach 98%, opens and waters success rate and can reach 100%.
