為使窯襯材料充分發(fā)揮效能，確保窯襯材料的使用周期，延長使用壽命，對耐火磚砌筑做了以下規(guī)定：

1、仔細清掃窯殼內壁的灰塵及渣屑；

2、窯殼內應平整沒有凹凸不平現象；

3、磚與磚之間灰縫控制在1.5mm~2mm；

4、膠泥的涂抹要均勻飽滿，不要有缺漿現象。均勻的涂抹膠泥，且用砌體搓動膠泥，使膠泥能微量擠出；

5、窯襯的砌筑要平整不能有錯臺，應力求避免錯位、傾斜、灰縫不均、離中、重縫、通縫、張口、脫空、毛縫、蛇形彎、砌體鼓包以及混漿等通?。?/SPAN>

6、耐火磚襯中的膨脹縫，必須按設計留設，不得遺漏；

7、重要部位和外形復雜部位的襯里應先進行預砌筑；

8、鎖縫要牢固。加工磚時要用切磚機對磚進行精細加工，不得使用手工加工磚；在回轉窯內及托磚板下的封頂磚應不小于原磚的70%；在平面的接頭磚和彎道磚中，不得小于原磚的1/2。必須用原磚鎖口。磚的加工面不宜朝向爐膛內側。

9、耐火材料必須在干燥庫房內存放。

The instruction of the refractory bricks’s masonry

????

In order to make the materical of kiln liner function fully and ensure its turnaround, prolong service life, making following provisions for the masonry:

1、Sweep carefully the dust and crumbs on the inside wall of kiln shell.

2、Inside wall of kiln shell should be level up and no irregularity phenomenon.

6、According to design, the expansion gap of firebrick must remain. You cannot omit.

7、You should masonry in advance in important and complex outline part of the klin lining.

8、Firm whipstich.You must process finely brick with brick cutter. Don’t? process brick with hand. Neck brick should be larger 70% than other brick. The last brick in one plane or the brick in a curve should be larger 50% than other brick. Must foreshaft with the same brick. The machined surface is not suitable to facing the inside hearth.

9、Refractory should be stored in dry warehouse.
