Improve the quick change method of ladle venting bricks

(Picture) Split Breathable Brick

The relationship between breathable bricks and ladle can be described as inseparable. There are many types of breathable bricks, and each kind of breathable brick has its own irreplaceable advantages. But water can carry a boat and it can overturn it. In different production situations, it is wisest to adopt the most suitable one. Integral air-permeable bricks are popular among steel mills due to their high thermal strength, good thermal stability, erosion resistance, and good slag resistance. However, they have encountered problems when they are used to manufacture high-quality special steel.

1. Veelgestelde vragen

The waste of resources caused by non-synchronization. After the venting bricks are corroded, the use times of the slag line are not equal. Therefore, when the life of the integral venting bricks expires, the number of input of new packages, new slag lines and other spare packages should be increased accordingly, and the tapping temperature of electric furnaces and refining furnaces will rise. This leads to serious over-oxidation of molten steel. This process will increase unnecessary smelting time, power consumption and consumption of raw materials.

Long cycle time exacerbates loss. The replacement cycle of integral ventilating bricks is long, the lining is damaged in the process, the service life of the ladle is shortened, and the consumption of refractory materials per ton of steel and gas increase correspondingly, and the labor intensity of workers is also increased.

The cleanliness of molten steel is affected. Due to the high difficulty of ladle turnover and unstable production rhythm, the cleanliness of molten steel is affected.

2. Rectification method

Change the integral ventilating seat brick to a split ventilating brick. Our split air-permeable bricks are cone-shaped, wrapped in stainless steel, with scientific and meticulous design, which is easy to disassemble and install.

The lower part of the breathable brick is tightened with a fastening mechanism (screw button type) to make it firm.

Synchronously clean the ladle, replace the breathable brick, and slide the nozzle. Greatly improve efficiency and save time.

Add a mobile operating platform, built-in simple tools such as wrenches, etc., making it easy to replace.
