Slag Pot
The slag pot is an important steelmaking equipment in the metallurgical industry. It is a container used to contain high-temperature molten slag generated in the process of steel smelting. It has a bowl-shaped container with lifting trunnions on both sides.
In production practice, the use of slag pot in ferroalloy smelting mainly has the following problems:
(1) Due to the design of the overflow port of the slag pot, the center of gravity of the slag pot is shifted, and the slag pot is inclined during the lifting process, and the slag liquid is easy to overflow, and there is a big hidden danger.
(2) The overall structure of the slag pot is unreasonable. After the thermal stress is applied, cracks are easily generated, and the cracks will cause bag penetration.
(3) It is designed to use one lined molten iron ladle and three slag ladle. Sometimes too much molten iron will overflow from the molten iron ladle into the slag pot, causing the temperature at the bottom of the slag pot to rise sharply, which will cause damage to the slag pot.
Improvement measures
1. Thicken the wall thickness of the slag pot inside the rear of the slag pot, so that the center of gravity can be balanced after the slag pot is lifted.
2. The improvement part is the removal of the upper reinforced side of the slag pot, the bottom and middle and upper parts of the slag pot are evenly thin, the bottom reinforced side is reserved for expansion joints, and the bottom is increased with strong ribs.
3. Change the structure of the tapping cart, from the original combination of three slag pot with a lined molten iron ladle to two lined molten iron ladles and two slag pot, which can effectively prevent molten iron from flowing into the slag pot, Causing local high temperature damage to the slag pot.
