What problems should be paid attention to when purchasing refractory bricks
According to the structure of the furnace: each part of the working characteristics and operating conditions, purchase the appropriate refractory brick. To analyze the reasons for the damage of refractory bricks, so that targeted selection of refractory bricks, at this point to increase the price of refractory bricks.
For example, the lining and bottom of the slag line and the following parts of the smelting furnace (such as the reverberation furnace) are mainly subjected to the chemical erosion of the slag and metal melt, followed by the thermal stress caused by the temperature sudden change, and the general selection of excellent slag resistance magnesium, magnesia chrome refractory brick masonry. Magnesia-aluminum brick or magnesia-chrome brick or high-aluminum brick can be used for the parts above the slag line.
