One of the obvious characteristics of the calcium treatad free-machining steel we have developed(40 CrCa) is that its machinabi-lity will, in a certain range of cutting speed improve as the cutting speed rises, and will reach the best of it when the cutting speed V = 200m/min. In this case, the tool will be given a life 8 times as long as that when cutting standard steel(40Cr).

我们所研制的含钙易切钢(40 CrCa)的可加工性具有一个明显的特点,即在某一切削速度范围内,这种钢的可加工性是随着切削速度的提高而改善的。当切削速度V≈200米/分时,可加工性达到最佳状态。此时刀具的耐用度为切削普通钢(40Cr)时的8倍。 这种易切钢的可加工性特别好的原因在于:用钨、钛、钴类硬质合金刀具(YT15)以高的切削速度切削这种钢时,钢中的球状氧化夹杂物会软化,并且沉积在刀具表面上形成一层薄膜,这层薄膜对刀具的磨损有阻碍作用。

A derivative spectrophotometric method is described for the determination of phosphorus in steel, using phosphovanadomolybdate blue-rhodamine B-galatin-OP system. In the determinations of three standard steel samples, the maximum relative standard deviation is 5.8%.

本文采用磷钒钼蓝—罗丹明B—明胶—OP体系以一阶导数分光光度法测定了碳素工具钢和低合金钢中的磷。对三种标准钢样测定的结果,最大相对标准偏差为5.8%,回收率在94~107%之间。

Determination of microamount copper by fluorescence quenching method has been investigated based on complex formation of Cu (Ⅱ) with meso-tetra (p-sulfophenyl) orphyrin.In the presence of CTMAB and Triton X-100 the sensitivity of the method proposed is 0.005μg/ml. When NaF is used as a masking agent, 1 mg of Fe (Ⅲ) does not interfere with the determination of Cu (Ⅱ). The contents of Cu in the powdered iron, iron oxide and standard steel samples are determined with satisfactory results.
