What do you need to know when buying огнеупорный кирпич?

What do you need to know when buying refractory bricks? What kind of furnace lining is used for refractory bricks? Can refractory bricks achieve practical application effects? How to purchase refractory bricks to achieve good results? Combining the actual situation, expounds the refractory brick procurement Issues that should be paid attention to.

1. Размещение печи из огнеупорного кирпича.

According to the structure of the furnace, the working characteristics and operating conditions of each part of the furnace, refractory bricks are selected to achieve targeted selection. For example, the lining and bottom of various smelting furnaces below the slag line (such as furnaces and reverberatory furnaces) are mainly chemically attacked by slag and metal melt, followed by thermal stress caused by temperature mutations. The masonry generally chooses magnesia and magnesia-chrome refractory bricks with good slag resistance. The above slag line can choose magnesia alumina brick, magnesia chrome brick or high alumina refractory brick.

2. Обеспечьте нормальную работу и общий срок службы печи.

Как и футеровка печи, должна быть гарантирована нормальная работа и общий срок службы печи. Разумно настраивать различные огнеупорные кирпичи, применяемые в различных частях печи. При определении различных частей печи и материалов каждого слоя одной и той же части избегайте химических реакций и повреждений при плавлении между разными огнеупорными кирпичами и убедитесь, что потери каждой части уравновешены, или примите разумные технологические меры для уравновешивания потерь. и обеспечить общий срок службы печи.

3. Характеристики огнеупорного кирпича.

когда buying refractory bricks, you should master the basic knowledge of refractory bricks, such as the composition of refractory bricks, the physical properties and working performance of refractory bricks, and whether it can achieve the expected effect as a furnace lining, so as to better exert the excellent characteristics of refractory bricks. For example, silica bricks for coke ovens have a high softening temperature under load and can resist acid slag erosion, but their thermal shock resistance is poor and can only be used for coke oven partition walls. Their soft load characteristics can be used in long-term high temperature environments.

2. Производители огнеупорного кирпича.

As a purchaser of refractory bricks, you only need to determine the index, size, performance and other information of refractory bricks to purchase common refractory bricks, and consult the refractory brick manufacturers whether they can make them, whether they can meet the specified requirements, and whether the processed refractory bricks can meet the requirements Characteristics and other information, this is the most basic integrity of refractory brick manufacturers.
