底板
mold stool
d IbQ门底板(mold Stool)用以承托钢锐模并在其上进行浇注作业的铸铁平板,也称底盘。对于无底钢锭模,如上小下大的敞口钢锭模或瓶口式钢锭模,底板将与钢水直接接触,并形成钢锭的尾部。采用单层或双层凹型底板,可以得到球缺形或截锥形的凸底钢锭,从而减少上小下大钢锭开坯时的“鱼尾”切损。下注底板铸有限定中心座砖(分钢砖)和流钢砖的凹穴和沟槽。底板上沟槽的分布形式有直角形、H形、放射形、树枝形等多种。(见图)大型钢锭多采用十字形或H形沟槽的底板,每个底板上可摆放4、6或8支钢锭模。小钢锭则多采用放射形或树枝形底板,每个底板上可摆放10一60支钢锭模。底板上凹穴和沟槽的形状与尺寸应与选用的分钢砖及流钢砖的规格相适应,并留出一定余量。一般情况下,砖与槽壁间的缝隙以10~15mm为宜。为了保证底板的强度和刚性,底板的厚度波动在100~25omm之间,钢锭重且支数多时取上限。为了减轻底板的重量和减化制造工艺,底板应尽量做得小些。设计底板的原则有:(1)在底板背面适当的地方做成凹槽;(2)流钢砖形状、种类要简单,尽量选用标准规格;(3)在留出必要间隙的前提下,锭模排列要紧凑,并要考虑改放几种不同锭型的可能性;(4)钢水流向要合理,尽量避免转90“弯,力求各个锭模内钢液面能同速平稳上升。底板必须平整.大型底板铸好后,要经大型龙门刨刨平。浇注小钢锭的底板,不再进行机加工,但要求铸造工艺保证表面平整。车铸时,底板安放在铸锭车上;坑铸时,底板相对固定在铸坑内或车间地平面上。新底板使用前必须烘烤至100一200℃。周转的底板首先要清除前次铸钢留下的残砖、汤道、填充砂等,然后仔细镶砌新的中心分钢砖、流钢砖以及安放中注管砖和中注管、钢锭模等。上注底板要喷涂一层防止钢锭与底板粘连的底板涂料,并放置注流缓冲料(如钢板切边、钢屑等)以及防溅筒等。姗{巫自 a6困颤猛 cd 底板沟槽布置类型示意图 。一直角形汤一H形;c一放射形、d一树枝形 (粼怎明杨建华)
