د ladle breathable brick

The refining process outside the furnace is now an important part of the steelmaking process. The argon blowing process at the bottom of the ladle is indispensable for refining outside the furnace, and the ladle air-permeable brick is the key element to realize this process. The current ventilating bricks are mainly divided into slits and impervious types. The performance of ventilating bricks is related to the quality and output of steel. Generally speaking, ventilating bricks should be compatible in life, bottom blowing effect, blowing force and safety. The daily turnover of steelmaking plants.

In terms of service life, bottom blowing effect and safety and reliability, compared with slit-type air-permeable bricks, air-permeable air-permeable bricks have the advantage of stable air permeability, which can effectively prevent steel seepage on the working surface of the air-permeable brick; After the steel pouring is finished, the ventilation rate can be met without cleaning or intermittent cleaning, which significantly reduces the labor intensity of the workers and also reduces part of the energy consumption; the service life is significantly increased, and the use of ventilation bricks is increased. Safety factor.

For slit air-permeable bricks, the number of slits and the form of single and double slits depend on the size of the ladle, the smelting environment and the required air volume, so the production process of this kind of air-permeable brick is more complicated; By controlling the particle size of the ingredients, a large number of pores running through the entire dispersed block are generated correspondingly, and the formed microporous structure is uniform, so the production process is relatively simple. There is a slit design at the bottom of the impermeable brick, which is equivalent to a small slit ventilating brick. In the process of use, when a slit gas channel is observed on the working face of the ventilating brick during hot repair, it indicates that the residual length of the ventilating brick is insufficient, and it is necessary The ladle is offline.

In domestic ventilating brick manufacturers, the performance of anti-permeable ventilating bricks is lower than that of slit ventilating bricks. Our company has achieved unprecedented results through scientific research and design, greatly improving the service life and bottom blowing effect of diffuse ventilating bricks.
