打孔

The 120m3 BF foundation temperature is reduced from 950℃ to below 700℃ and the furnace life campaign is prolonged for more than 2 years by taking furnace maintenance measures such as batching schreyerite in burdens to deposit Tion hearth bottom to form a steady protective layer and make molten iron liquidity slower to slowdown the erosion on bottom, drilling holes to lay water-cooling pipes in heat resistant foundation to heighten the 1150℃ isothermal line of molten iron to make frozen metal layer thicker.

对济钢120m3高炉炉底侵蚀状况，在生产中配加钒钛矿，使其还原成Ti的沉积，以对炉底形成稳定保护层，降低铁水流动性，减缓铁水对炉底冲刷；同时在耐热基墩打孔，穿埋水冷管，促使炉缸铁水1150℃等温线上移，凝固团增厚。实践表明，特护期间炉基温度由950℃下降至700℃以下，炉役寿命延长2年以上。

They are already employed industrially to shape soft and light metals, such as aluminium and copper. Now a group of researchers at the Fraunhofer Institute for Machine Tools and Forming Technology in Chemnitz, Germany, has found a way to use an EMP device to shape and punch holes through industry's metallic heavyweight—steel.

它们已经用于工业加工如铝和铜等的柔软轻金属造型，如今，德国开姆尼茨的夫琅和费研究所里一群钻研机械工具和造型技术的研究人员发现，可以利用EMP装置给工业用重金属钢材造型和打孔。

The new plant covers an area of 45,000 square meters, the introduction of the most advanced equipment, ping bending steel production line, with Paul Quintero automatic cutting machine, straight-line Edger machines, special-shaped milling machine, drilling machine, washing machine, chamfering machine.

新厂房占地面积45000平方米，引进国内最先进的设备平弯钢化生产线，配备保特罗自动切割机、直线磨边机、异形磨边机、打孔机、清洗机、倒角机。

If you work in a factory,you usually have to punch a clock.

如果你在工厂工作的话，你就需要在上下班记时卡上打孔。
