回炉料

In this paper,the experiment results for a spherical ammonia catalyst prepared from remelt scrap are reported by using spheroidizer and sintering furnace.

进行了回炉料经成型和烧结等工艺制备球形氨合成催化剂的实验室研究。

Remelt the AZ91D magnesium ingot together with different weight ratio recycled scrap in this experiment.

本文利用AZ91D镁合金锭作为原料，分别将它们加入不同含量的回炉料进行重熔，分析用回炉料生产的镁合金重熔后的组织和性能。

Due to the company's existing wire line back edge charge, so there is a large part for the steel plant, precision casting company, in general a month for 200 tons -350 tons.

因本公司现有边丝系回炉料，所以有很大一部分可供炼钢厂、精密铸造公司，一般每月可供200吨-350吨。

Of raw materials to make ALE Series Stroke Stop and Stroke Switch use of carbon steel, ordinary gray cast iron or ductile iron back to BURDEN; reduce the liquid iron in the alloy elements such as Cr, Mn and other content, reducing its molten iron-containing gas; before the next core sand core all the overhead brush paint and the storage period to prevent the sand core to absorb moisture; in rainy days or high humidity of the season, the next best to use torch to the former core cavity, the surface of sand core baking again, in order to reduce sand-fat content; high-temperature casting a small valve in order to facilitate their own exhaust and the reduction of molten iron casting slag produced.

6原料尽量使用碳钢、普通灰铸铁或球墨铸铁回炉料；降低铁液中的合金元素如Cr、Mn等含量，减少铁液自身含气量；将下芯前的砂芯全部架空刷涂料且限期存放，以防砂芯吸潮；在阴雨天或湿度较大的季节，下芯前最好用喷灯将型腔、砂芯表面烘烤一遍，以减少砂型发气量；采用高温浇注小阀门，以利于铁液自身排气和减少铸渣产生。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
