The medium and high carbon steels were quenched with and without magnetic field in the self-made quench tank,the austenite transformation in the NaCl solution was studied,and the microstructure change after phase transformation was observed.
利用自制的磁场热处理设备对中、高碳钢进行了施加磁场与不施加磁场的淬火处理,研究了奥氏体在NaCl溶液中冷却时的组织转变,观察了相变后的组织变化。
The goaf gas drainage is carried out by drilling holes with strike and middle-high-order at the π type caving coal face in the inflammable and high coal seam.
易发火特厚煤层π放工作面利用走向中高位钻孔实施采空区瓦斯抽放,解决了工作面瓦斯超限制约工作面生产的问题,效果显著,为低瓦斯矿井实现高体积分数瓦斯抽放提供了可行性依据。
