Description
Technical Field
The invention relates to a method and a device for controlling automatic slag splashing gun positions of a converter, electronic equipment and a storage medium, and belongs to the technical field of converter steelmaking.
Background
The slag splashing furnace protection technology is to utilize the MgO content to reach the saturated or supersaturated steelmaking end slag after the tapping of the converter is finished, cool and solidify the slag layer with high melting point on the surface of the furnace lining through the splashing of high-pressure nitrogen in the oxygen lance, and well adhere to the furnace lining. The slag splashing layer formed by the slag splashing has better corrosion resistance, can inhibit oxidation and decarbonization on the surface of the furnace lining brick, and can reduce erosion and scouring of high-temperature slag to the furnace lining brick, thereby protecting the furnace lining brick, reducing the loss speed of refractory materials, reducing the consumption of gunning materials, simultaneously reducing the labor intensity of workers, prolonging the service life of the furnace lining, improving the operation rate of a converter and reducing the production cost. The slag splashing furnace protection is a great improvement of the converter protection technology, can greatly improve the converter life and reduce the refractory material consumption, and has wide popularization and application prospects.
The refractory brick of the converter lining is mainly a magnesia carbon brick, the carbon content is generally 14-18%, and the magnesia carbon brick has the advantages that: the inside contains carbon, is not wetted to slag, can resist slag erosion, and forms a carbon network after the bonding agent is solidified, thereby playing a role of a framework; meanwhile, the carbon has good heat conduction performance, can uniformly transfer heat, and avoids cracks of the magnesia carbon brick caused by uneven heating. The formation of the slag layer of the converter is roughly divided into three steps: (1) The part with better fluidity in the slag is firstly combined with the furnace brick, and is permeated, sintered and attached along the tiny cracks and pores on the surface of the furnace brick; (2) After forming the bonding surface, the high-melting point minerals (dicalcium silicate, tricalcium silicate and the like) in the slag are splashed by high-pressure nitrogen and are inlaid on the formed sintering layer; (3) In the process of continuously spraying nitrogen, the formed slag layer is continuously cooled and solidified, and a slag splashing layer is formed on the furnace lining.
The melting temperature of converter slag is only about 1450 ℃, and melting starts early at about 1300 ℃, but because of the existence of a high-melting-point phase (the melting point of tricalcium silicate can be higher than 2000 ℃), the low-melting-point phase (ferric oxide, calcium silicate and the like) in the slag splashing layer is dissolved in the blowing process, and the high-melting-point phase is left, so that the high-melting-point substances in the slag splashing layer are increased and the low-melting-point substances are reduced after continuous blowing and slag splashing are performed, and a stable slag splashing layer is formed.
Of course, the final slag components such as alkalinity, mgO content, feO content, proper slag quantity, final slag temperature, nitrogen pressure and flow, oxygen lance technological parameters, oxygen lance position control, bottom blowing of a combined blown converter, slag splashing time, steel grade end point control target requirements, various factory technological equipment, furnace burden results, technical operation level, management requirements and the like influence the slag splashing protection effect, and high importance and overall consideration are needed.
The control of the slag splashing furnace protection gun position is critical, and the lower gun position is generally considered to splash the furnace body, and the higher gun position splashes the molten pool. The nitrogen can not form enough impact force on the slag when the gun position is high, so that the slag forms a surge in a molten pool and continuously surges to adhere to the molten pool, and when the gun position is low, the high-pressure nitrogen impacts the slag, so that the slag forms slag particles and is splashed to adhere to a furnace body, but the gun position is not too deep to prevent the slag from splashing to a furnace mouth part, so that the furnace protection effect can not be realized. The slag is normally cooled firstly, then the gun position is lifted, and in the slag splashing process, the gun is slowly lowered according to the condition of slag particles at the furnace mouth, so that the slag is uniformly covered by the slag layer from the molten pool to the furnace body. The slag splashing protection requirements of different furnace times in different periods are different, and the erosion degree of each part of the furnace lining refractory bricks is inconsistent, so that the slag splashing protection key points of each furnace time or each furnace time are also changed, and the gun position of the slag splashing protection furnace is required to be correspondingly adjusted in time so as to ensure the slag splashing protection effect of each furnace time.
