What do you need to know when buying refractory cib?

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. Kiln qhov chaw siv cov cib ua hluav taws kub

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. Ua kom muaj kev ua haujlwm ib txwm muaj thiab tag nrho lub neej ntawm lub cub tawg

Raws li txheej txheej ntawm lub qhov cub, kev ua haujlwm ib txwm muaj thiab kev ua haujlwm tag nrho ntawm lub qhov cub yuav tsum tau lav. Tsim nyog tsim kho ntau yam khoom siv hluav taws xob uas siv hluav taws xob siv hauv ntau qhov chaw ntawm lub cub tawg. Thaum txiav txim siab ntau qhov chaw ntawm lub tshuab ua kom sov thiab cov khoom siv ntawm txhua txheej ntawm ib feem ib sab, zam kev tshuaj lom neeg thiab ua kom puas ntawm cov cib sib tsoo sib txawv, thiab ua kom ntseeg tau tias qhov poob ntawm txhua feem yog sib npaug, lossis siv cov txheej txheem tsim nyog los sib npaug qhov poob. thiab xyuas kom tag nrho lub neej ntawm lub cub tawg.

3. Cov yam ntxwv ntawm cov cib refractory

thaum 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. Refractory cib manufacturers

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.
