Cold drawing

原声例句
5.哈利波特与凤凰社

Harry could hear his voice echoing up through the floor in the cold drawing room where he was sitting alone, watching the sky growing whiter outside the windows, threatening snow.

哈利昕到他的声音从楼板间传来,而他一个人坐在这问冷冰冰的客厅里,看着窗外的天空越来越白,要下雪了。

Drawing (manufacturing)

(重定向自Cold drawing)
The basic drawing process for a wire, bar or tube.

Drawing is a metalworking process which uses tensile forces to stretch metal. As the metal is drawn (pulled), it stretches thinner, into a desired shape and thickness. Drawing is classified in two types: sheet metal drawing and wire, bar, and tube drawing. The specific definition for sheet metal drawing is that it involves plastic deformation over a curved axis. For wire, bar, and tube drawing the starting stock is drawn through a die to reduce its diameter and increase its length. Drawing is usually done at room temperature, thus classified a cold working process, however it may be performed at elevated temperatures to hot work large wires, rods or hollow sections in order to reduce forces. Drawing is one type of extrusion.
