线性聚能切割器切割钢板的实验研究

概述了聚能装药的切割原理和实验目的,介绍了实验所用的几种线性切割器的主要性能。根据聚能切割器切割钢板的实验,为上海钢铁厂钢结构厂房的切割爆破拆除选定了切割器类型。通过实验认识到,切割器的爆轰形成阶段,不能使钢板达到正常的切割深度。为此,当采用一端起爆时,切割器的起爆端必须超出钢板边缘一定长度,才能取得良好的切割效果。与普通外部装药爆破相比,应用线性聚能切割器具有节省炸药、切割快速、方便和降低成本等优点。

AN EXPERIMENTAL STUDY ON USE OF LINEAR CUMULATIVE CHARGE FOR CUTTING OF STEEL PLATE

The cutting principle of cumulative charge and the experimen tal object were outlined and main performances of some linear cumula tive charges used in experiments w ere introduced Based on the experi ments on use of cumulative charge for cutting of steel plate,the typ e of cumulative charge was determi ned for explosive cutting demoliti on of steel structural factory hou ses in Shanghai Iron & Steel Co It is considered through the experime nts that the detonating stage of a cumulative charge can't produce no rmal cutting depth When using end initiation,for this reason,the det onating end of a cumulative charge must has a certain extension over the edge of steel plate,so that a good cutting effect is gotten As c ompared with common contact blasti ng,use of linear cumulative charge has the advantages of less explosi ve,rapid and easy cutting and lowe r cost
