Improving efficiency of automatic flame cutting machines - by using very high purity oxygen@ for the flame cutting

摘要

Autogenic flame cutting uses oxygen. The purity of the oxygen used is greater than 99.8%, esp. 99.9-99.99%. USE/ADVANTAGE - Use of high purity O2 for digitally controlled flame cutting machines increases the efficiency of the machines by ca. 10% and lowers the total prodn. costs by ca. the same amt..
