Dema ku hûn kevirên nefret bikirin divê hûn çi zanibin?
What do you need to know when buying kerpîçên bergirî?
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. Cihê kûştinê bi tuxleyên nefermî bikar tîne
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. Operasyona normal û jiyana giştî ya firnê misoger bikin
Wekî xêzika kewarê, pêdivî ye ku xebata normal û jiyana karûbarê giştî ya firnê were garantî kirin. Bi maqûl cûrbecûr kevirên nehf ên ku li deverên cihêreng ên firnê têne bikar anîn vesaz bikin. Dema ku hûn perçeyên cihêreng ên firnê û materyalên her perçeyek ji heman perçê diyar dikin, ji reaksiyonên kîmyewî û zirara helandinê di navbera kevirên cûrbecûr ên nefermandar de dûr bisekinin, û pê ewle bine ku wendakirina her perçê hevseng e, an jî ji bo balanskirina wendabûnê tevdîrên pêvajoya maqûl bigirin. û jiyana giştî ya firnê misoger bike.
3. Taybetmendiyên kerpîçên bergir
Heke 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. Hilberînerên kevirên nesekinî
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.
