贯通式输送带-贮料库

在加工箱体零件的自动线系统中,贯通送带—贮料库获得愈来愈广泛的应用。贮料库(如图1)应用于下述情况:(1) 作为装料装置1和卸料装置2;(2) 用于连接位于同一平面的和顺序的自动线,其输送方向分为一致的(如送带—贮料库3直接连接的自动线Л_1和,平行的(如自动线Л_2和有输送带—贮4的自动线Л_3)或垂直的(如自动线有输送带—贮料库5的自动线Л_5);(3) 用于分开和连接系统中平行工作多支线自动线的各支线,如借助输送带料库6将自动线Л_6分成支线Л_6/1％和Л_6/2,过输送带—贮料库7将它们与自动线Л_7连     

THE PREPARATION AND CHARACTERISTICS STUDY OF TiNxOy SPECTRAL SELECTIVE ABSORBING FILM BY MAGNETRON SPUTTERING

Spectral selective absorbent film is a crucial factor for the solar heating device. There are many kinds of spectral selective absorbing film made by different ways. TiNxOy thin film with excellent spectral selecting absobent property were successfully prepared by DC magnetron sputtering with Ar as working gas, N2 and O2 as reactive gas, 99.9% titanium as the target and is copper slice as the substrate. In this article, the optical characteristics and microstructure of TiNxOy thin film were studied. Inputing O2 can decrease the reflection of the visible lights, and double layer film can get good absorption for solar energy.     

Advances in the research of nitrogen containing stainless steels

The current status of nitrogen containing stainless steels at home and aboard has been introduced. The function and existing forms of nitrogen in the stainless steels, influence of nitrogen on mechanical properties and anti-corrosion properties as well as the application of nitrogen containing cast stainless steels were discussed in this paper. It is clear that nitrogen will be a potential and important alloying element in stainless steels. And Argon Oxygen Decarbonization (AOD) refining can provide an advanced manufacture process for nitrogen containing stainless steels with ultra-low- carbon and high cleanliness.

包中精炼装置的设计、实现及其在锻造钢锭上的应用

CREUSOT-LOREI公司的布勒伊钢厂曾于一九七九年底安装了一套100t电弧加热的钢水包精炼装置。本文简要介绍一下该装置的情况及其操作方法。使用结果表明:电炉的生产常大大得到改善,同时又降低了铁合金的费用,用单独一台电炉即可生产出其重量需用两炉钢水的钢锭。改善了成分的分散情况,能获得很低的硫、磷含量,可按常规进行操作,又具有很大的可靠性。浇注温度的调节有明显改善。包中精炼看来是一种极好的手段,可以用来生产高级钢锭,经济效果也很好。
