What do you need to know when buying vatrostalne opeke?

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. Položaj peći pomoću vatrostalnih opeka

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. Osigurajte normalan rad i ukupni vijek trajanja peći

Kao obloga peći, mora se zajamčiti normalan rad i ukupni vijek trajanja peći. Razumno konfigurirajte različite vatrostalne opeke koje se koriste u različitim dijelovima peći. Prilikom određivanja različitih dijelova peći i materijala svakog sloja istog dijela, izbjegavajte kemijske reakcije i oštećenja otapanja između različitih vatrostalnih opeka i osigurajte da je gubitak svakog dijela uravnotežen, ili poduzmite razumne mjere procesa kako biste uravnotežili gubitak i osigurati ukupni vijek trajanja peći.

3. Karakteristike vatrostalnih opeka

Kada 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. Proizvođači vatrostalne opeke

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.
