Do you know the application of magnesium carbon bricks at all parts of the turntable furnace lining?
Magnesium carbon bricks have been widely used on steel smelting equipment because they have excellent high temperature resistance, slag erosion capacity, and good thermal shock stability. It is difficult to use carbon materials to be wokened by stakes, steel liquid wetness and magnesium, high fire resistance, high residual resistance and soluble resistance, and small temperature creep. Steel side and other parts.
A Furnace mouth
The temperature of the furnace mouth changes fiercely, and the scrubbing of the slag and high -temperature furnace gas is relatively powerful. When the ingredients and residual steel and residue are cleared, the furnace mouth is impacted. Therefore, the refractory bricks used for the furnace mouth must be a high heat shock resistance and residue resistance, slag resistance and high -temperature furnace gas, and not easy to stick steel, even sticky steel, which is easy to clean up.
B Furnace
The furnace hat is the most serious part of the slag erosion, and at the same time, it is also affected by the rapid changes in temperature and the scouring of dust -containing exhaust gas. Therefore, the magnesium carbon bricks with strong slag resistance and heat -resistant treacherous should be used. In addition, when the furnace hat is inconvenient to build the heat insulation layer, the magnesium sand resin can be filled between the permanent layer and the steel shell steel plate.
C Furnace lining material side
In addition to the bleeding process of the furnace lining process and the splashes of steel splashes and chemical erosion, it is also subject to direct impact and erosion when it is loaded with scrap steel and mixed with iron water. Therefore, magnesium carbon bricks with high resistance, high -strength, high -strength, high -strength, high -strength, high -strength, high -strength, high -strength, high -resistant, high -heat shock bricks.
D Furnace lined with steel side
The furnace lining the steel side is basically not affected by the mechanical collision damage when it is installed, and the thermal earthquake effect is also small. It is mainly due to the heat impact and scour effect of the steel when the steel is expelled. The damage speed is lower than the loading side. If the same material is mixed with magnesium carbon bricks with the same material, the thickness of the masonry can be slightly thinner.
E Slag line
During the blowing process, the long -term contact between the furnace lining and the slag was severely eroded. On the side of the steel side, the position of the slag line changes with the length of the steel time, and most of the cases are not obvious; but the slag discharge side is different, and the slag is strongly eroded. The joint influence, the damage to the bricks is more serious, and the magnesium carbon brick with good masonry resistance is required.
F On both sides of the axis
Except for the damage of the blowing process on both sides of the hem shaft, the surface is not covered with a protective residue layer. The carbon in the brick body is easily oxidized and it is difficult to repair, which is severely damaged. Therefore, this part should be mixed with magnesium carbon bricks with good resistance and strong antioxidant performance.
