High-strength converter tapping slag stopping mechanism capable of improving operating efficiency and processing technology thereof

Abstract

The invention relates to a high-strength converter tapping slag stopping mechanism capable of improving operating efficiency and a processing technology thereof and belongs to the technical field of cast iron processing. The high-strength converter tapping slag stopping mechanism capable of improving the operating efficiency comprises a slag stopping mechanism body, a mechanism cooling system, an oil cylinder, a hydraulic system and a hydraulic cooling system. The mechanism cooling system is communicated with the slag stopping mechanism body through a pipeline. The output end of the oil cylinder is connected with the slag stopping mechanism body and used for driving the slag stopping mechanism body. The oil cylinder, the hydraulic system and the hydraulic cooling system are sequentially communicated through pipelines and form a loop. The sliding face of a sliding mold frame is in an oil groove type horizontal sliding mode. Compared with other similar slag stopping mechanisms, the safety risks caused by roller abrasion and axle fracturing of an axle-roller type slag stopping mechanism are eliminated completely.

Description

technical field [0001] The invention relates to a high-strength converter tapping slag retaining mechanism capable of improving operating efficiency and a processing technology thereof, belonging to the technical field of pig iron processing. Background technique [0002] A converter is a type of steelmaking furnace. The furnace body is cylindrical, mounted on a horizontal shaft frame, and can be rotated. Reducing the amount of slag in the tapping process of the converter is an important link to improve the quality of molten steel, and it is also one of the problems that will affect the development of steelmaking for a long time. In order to optimize converter slag blocking technology at home and abroad, more than a dozen slag blocking methods have been invented, such as slag blocking caps, slag blocking balls, slag blocking plugs, pneumatic slag blocking methods, electromagnetic slag blocking methods, vacuum slag suction methods, and siphon tapping methods. However, the s...

Problems solved by technology

In order to optimize converter slag blocking technology at home and abroad, more than a dozen slag blocking methods have been invented, such as slag blocking caps, slag blocking balls, slag blocking plugs, pneumatic slag blocking methods, electromagnetic slag blocking methods, vacuum slag suction methods, and siphon tapping methods. However, the success rate of slag blocking is low and the effect is not ideal

And because the slag blocking mechanism is located in the high-temperature smelting area, the slag blocking mechanism is easily deformed by high-temperature baking during the converter blowing process, and even burned out for a long time and cannot be used, so it has to be replaced frequently. The existing converter slag blocking mechanism Complex structure, inconvenient installation, time-consuming and labor-intensive

[0003] In the current slag blocking mechanism, the axle-roller type slag blocking mechanism will cause safety risks due to the wear of the roller and the breakage of the wheel shaft; the plane sliding slag blocking mechanism may be stuck during operation, causing safety risks
