Metallurgical continuous casting workshop burial pit

Abstract

The invention relates to a metallurgical continuous casting workshop burial pit. The metallurgical continuous casting workshop burial pit comprises a burial pit body, and the burial pit body is provided with anti-collision piles arranged on the inner side wall of the burial pit; protective steel plates are arranged between the adjacent anti-collision piles; a pit top anti-collision beam is arranged at the top of the pit wall; and a side wall protection plate is arranged on the outer side wall of the burial pit and extends downwards from the top of the pit wall to form collision protection on the outer side wall. The pit wall of the burial pit is of a multi-layer composite structure, the outer layer is made of reinforced concrete, the middle layer is provided with a heat preservation material serving as a heat preservation layer, the inner layer is provided with the anti-collision piles and protective steel plates, the pit bottom base layer is made of reinforced concrete, stacking feet are installed on the pit bottom, drainage ditches are arranged on the periphery, and water drawing wells are arranged on the outer side. According to the burial pit, the protection structures are provided for the inner side wall, the outer side wall and the top of the pit wall of the burial pit, so that each vulnerable part of the burial pit can be protected to the greatest extent, the impact resistance of the burial pit is improved, the service life of the burial pit is prolonged, and local maintenance is easy.

Description

technical field [0001] The invention relates to the technical field of a slow cooling device for metallurgical continuous casting steel products, and more specifically relates to a slow cooling pit in a metallurgical continuous casting workshop. Background technique [0002] In the chemical composition of steel, if the amount of hydrogen is too high, white spots will appear in steel products. If steel with white spots is used for parts processing, the white spots will interfere with normal operation during processing, resulting in processing Scrapping of process semi-finished products. If there are white spot defects in steel products, even if the processing is successfully completed, the finished product after processing will affect its structure due to white spot defects, shortening the reliability and service life of parts and components, and even causing serious car crashes and fatalities. safety incidents. [0003] Then, reducing the hydrogen content in steel and elim...

Problems solved by technology

The insulation layer in the above-mentioned hot billet insulation pit is not equipped with a protective wall. When the steel billet hits the insulation layer when it enters the pit, it is easy to cause damage to the insulation layer. Once the insulation layer is hit and falls off, the concrete base of the insulation pit will soon be damaged and burned. After the concrete exposed reinforcement is damaged, the insulation pit can no longer provide the function of insulation
