Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of LF furnace water -cooling furnace cover structure, especially the semi -arc water -cooling furnace cover with four hole layout. BACKGROUND

[0002] The LF furnace water -cooling furnace cover is the core part of LF furnace, and plays a key role in the production of LF furnace. In the long-term use process, a large amount of steel slag is generated in the interior of the water -cooling furnace cover, which is not easy to fall off. The accumulation of steel slag causes the water -cooling furnace cover to be easy to scratch and strike the electrode, and even causes the molten steel tank to be unable to enter the heating position, affecting production. The Chinese utility model patent with the application number 201620095628.9 discloses a LF furnace water -cooling furnace cover. A hollow truncated cone body with a small upper part and a large lower part is arranged at the lower part of the furnace cover cylinder. At least two cooling annular pipes are arranged from top to bottom along the entire furnace cover wall. The inside of the cooling annular pipe is filled and flattened by welding. Each end of each cooling annular pipe is provided with a stop valve. The furnace cover is buckled on the large tank, and the smoke can be controlled to escape.

[0003] The Chinese utility model patent with the application number 202221658937.4 discloses a LF furnace water -cooling furnace cover slag scraping device. The device includes a rotary drive mechanism, a slag scraping arm, a slag scraping machine cutter head and a lifting mechanism. The rotary drive mechanism is installed on the lifting mechanism, and drives the slag scraping arm to rotate. The slag scraping machine cutter head is installed at the end of the slag scraping arm. The lifting mechanism is fixed on the molten steel tank transport vehicle. The surface structure of this slag scraping structure is complex, and the steel slag is easy to accumulate on the surface. The service life is low. In severe cases, the new water -cooling furnace cover must be replaced. A large amount of steel slag accumulation and falling off can easily cause personal injury and safety hazards. UTILITY MODEL CONTENTS
