3.3、安装NO.67、NO.78、NO.77；
Install NO.67,NO.78,NO.77；
3.4、调整好支柱轴线的位置，确保轴线偏差符合要求；
Adjust the column axis line position; ensure the axis line deviation meet with requirement.

3.5、通过调节螺杆、螺母来调整支柱的垂直度，支柱垂直度≤2/1000；
Regulate the bolts and nuts to maintain the verticality of the supporting column, the column verticality ≤2/1000.
3.6、复核相邻支柱间的尺寸（每一排支柱之间的距离误差±2.5；与该方向垂直方向支柱间距±4；）。将定位块按照设计要求塞紧，保证支柱的稳定性（调整支柱整体平整度±2㎜）。
Recheck the distance between two adjacent columns (the distance error of each row of column shall be ±2.5; the column distance of vertical direction column shall be ±4). The locating block shall be fixed tightly to maintain the supporting column stable (regulate the planeness of supporting column, maintain the planeness ±2㎜)
4、炉箅子安装
HBS grate installation
4.1、支柱安装完成后进行炉箅子的安装，炉箅子的安装从中心开始安装。
火焰电视After the installation of the supporting column, install the HBS grate, the installation starts from the center part.
4.2、每安装一块，均要注意其格孔和支柱，格孔中心对正，并随时检查调整相邻炉篦子中心距和炉篦子上表面水平度。 Pay attention to the grate checker hole and column during install each of the grates, the center of the grate checker hole shall be aligned, and adjust the grate center distance and surface planeness of every two adjacent grates.
4.3、炉箅子安装时要注意：吊装时要平吊，避免对支柱产生冲击。
During install the HBS grate, pay attention to the lifting direction, it shall be horizontal lifting and avoid of colliding with supporting column.
5、炉箅子调整

5.3、炉箅子的调整步骤
Adjusting steps of stove grate:
5.3.1、用细铁丝在炉箅子平面以上拉出热风炉炉箅子安装的中心线，固定在炉壳上，以此作为炉箅子调整的基准。
Draw the installation center line of HBS grate above the grates by thin steel wire, fix the centerline on the stove shell, and this steel wire will be used as the baseline for grate adjusting.
5.3.2、调整从中心炉箅子开始调整，要保证同一块炉箅子在同一水平面上。
The adjusting starts from the center part, ensure that the same single piece of grate shall be in same level plane.

5.3.3、中心炉箅子调整好之后，外侧的炉箅子以此为基准进行调节。调解时用12㎜的钢板夹在炉箅子之间的缝隙中，防止炉箅子偏移。调整完成后用套环把相邻的三块炉箅子卡住。
After adjusting the central grates, adjust the outside grates and take the central grate as reference. During grate adjusting, put 12mm steel plate between the gap of grates to avoid the grates drifting. After adjusting, use socket ring to clamp every three adjacent grates.
5.4、相邻炉箅子之间的孔调整后应该是一个圆形，对个别不成圆形的孔可以进行打磨。炉箅子调整完成后，复核所有的尺寸直至满足要求。
