Abstract

The invention provides a steel separating agent for a rotary platform and a furnace cover of a ladle refining furnace and a method for preventing the steel bonding of the rotary platform and the furnace cover of the ladle refining furnace, wherein the steel separating agent comprises the following components in percent by weight: 8-15 percent of high-alumina aggregate powder, 5-8 percent of quartz sand powder, 4-6 percent of silica micropowder, 25-35 percent of phosphorus-sheet graphite powder, 5-10 percent of zircon sand powder, 4-8 percent of organic bentonite, 10-18 percent of aluminium dihydrogen phosphate liquid and 15-25 percent of water. After the steel separating agent provided by the scheme is adopted, the difficult problem of steel bonding at all parts of the ladle refining furnace is effectively solved, the normal refining production time is greatly saved, the steel refining environment is effectively improved, the original fussy working for repeatedly bedding asbestos plates is eliminated, the production cost and the production time are greatly saved, and the economic value is higher.

Description

technical field

[0001] The invention relates to the technical field of metallurgy, in particular to the anti-adhesive steel treatment technology for a rotary table of a ladle refining furnace used in steelmaking production and a furnace cover, and a steel-separating agent applied to the technology. Background technique

[0002] At present, the ladle refining furnace, as one of the important external refining equipment in the steelmaking system, undertakes the refining tasks of various special steels and high-quality steels, and has many applications in the field of steelmaking.

[0003] The three ladle refining furnaces used in the No. 1 rolling mill of Valin Lian Iron and Steel Co., Ltd. are affected by various factors. A hook withdrawal slot is slotted next to the support arm of the table, which is convenient for the driving hook to enter and exit.

[0004] Due to the harsh working environment of the rotary table of the ladle refining furnace, a large amount of molten ste...
