Was ist beim Kauf von feuerfesten Steinen zu beachten?

What do you need to know when buying Feuerfeste Ziegelsteine?

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. Ofenstandort mit feuerfesten Steinen

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. Stellen Sie den normalen Betrieb und die Gesamtlebensdauer des Ofens sicher

Als Auskleidung des Ofens muss der normale Betrieb und die Gesamtlebensdauer des Ofens gewährleistet sein. Angemessene Konfiguration verschiedener feuerfester Steine, die in verschiedenen Teilen des Ofens verwendet werden. Vermeiden Sie bei der Bestimmung der verschiedenen Teile des Ofens und der Materialien jeder Schicht desselben Teils chemische Reaktionen und Schmelzschäden zwischen verschiedenen feuerfesten Steinen und stellen Sie sicher, dass der Verlust jedes Teils ausgeglichen wird, oder treffen Sie angemessene Prozessmaßnahmen, um den Verlust auszugleichen und gewährleisten die Gesamtlebensdauer des Ofens.

3. Die Eigenschaften von feuerfesten Ziegeln

Wann 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. Hersteller von feuerfesten Ziegeln

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.
