Problems solved by technology

At present, the commonly used method is to directly use the crawler forklift to shovel the cooled and dried steel slag into the large slag tank. Each tank needs to be shoveled into 2-3 buckets. During the operation, the steel slag needs to be recycled, which not only produces a lot of dust , and increased the amount of mechanical work, wasting manpower and material resources, reducing work efficiency and increasing energy consumption

specific Embodiment approach

[0017] A spraying process of a large slag tank, this process includes the following process steps: adding water and slaked lime into the container, stirring with compressed air; spraying the uniformly stirred spray paint on the inner wall of the large slag tank and the inner tank with a spray gun on the bottom.

[0018] In the spraying process of the above-mentioned large slag tank, the weight ratio of water and slaked lime added to the container is 7-10:1; the pressure of the compressed air used when stirring with compressed air is 0.4-1 MPa, and the stirring time is 3-10 Minutes; when spraying with a spray gun, the temperature of the large slag tank is 400-500 °C.

Embodiment 1

[0019] Embodiment 1: the container adds water and slaked lime that weight ratio is 7: 1, the pressure of the compressed air used when stirring with compressed air is 0.5 MPa, and the stirring time is 5 minutes; The temperature is 400°C, and the implementation effect: there is basically no dust pollution, no sticking phenomenon occurs, the oil consumption per ton of slag is 0.21 liters, and the frequency of construction machinery failure is 0.5 times / day.

Embodiment 2

[0020] Embodiment 2: the container adds water and slaked lime with a weight ratio of 9:1, the pressure of the compressed air used when stirring with compressed air is 0.6 MPa, and the stirring time is 5 minutes; the temperature of the large slag tank when spraying with a spray gun The temperature is 450°C, and the implementation effect: there is basically no dust pollution, no sticking phenomenon occurs, the oil consumption per ton of slag is 0.21 liters, and the frequency of construction machinery failure is 0.5 times / day.

Abstract

The present invention is aimed at providing a spray-coating process for large cinder ladle. Said process includes the following steps: 1. adding hydrated lime powder and water into a container and stirring them; and 2. using spray-coating gun to spray-coat the lime water onto the inner wall of large cinder ladle and interior ladle bottom.

Description

technical field [0001] The invention mainly relates to a large slag pot spraying process, in particular to a large slag pot spraying process for undertaking high-temperature molten slag produced by converter smelting. Background technique [0002] The 33 cubic meter large slag tank is used to undertake the high-temperature molten slag produced by converter smelting. It is required that the large slag tank transported to the converter for slag delivery must be backed with dry steel slag to prevent steel slag and residual molten steel from sticking to the tank. At present, the commonly used method is to directly use the crawler forklift to shovel the cooled and dried steel slag into the large slag tank. Each tank needs to be shoveled into 2-3 buckets. During the operation, the steel slag needs to be recycled, which not only produces a lot of dust , and increased the amount of mechanical work, wasting manpower and material resources, reducing work efficiency and increasing ener...
