白口倾向 meaning in English
chilling tendency
chillingtendency
Examples
- In order to decrease chilling tendency , it is suggested to shorten holding time of molten iron at high temperature ; adopt nodularizing alloy with low rear earth content ; reduce trace elements and bismuth contents of the metal charge
为减小球铁的白口倾向,建议:缩短高温停留时间;采用低稀土球化剂;加强炉料控制,减少微量元素,避免铋量过高。 - The main reasons causing increased chilling tendency of nodular iron are as follows : using metal charge containing trace and alloy elements which can increase chilling tendency ; molten iron being holded at high temperature too long ; abnormal nodularizing and / or inoculation treatment , as well as abnormal composition control
摘要引起球铁白口倾向大的主要原因是:炉料稳定性差、电炉保温、球化处理及铁液成分控制和孕育处理出现异常。 - Abstract : by utlizing abundant local resource of ytirium and combining the characteristics of magnesium , barium , calcium and silicon , a sort of composite nodulizer - ytirium - based heavy rare earth nodulizer was developed which is characterized by its good desulphurizing and deoxidizing rate effect , excellent effect to neutralize anti - nodulizing effect of trace elements , strong nodulizng effect and degeneration - resistance , good effect to fine matrix structure , decreased chilling tendency and wide scope of applicatiom using this nodulizer to produce some important castings such as water - cooled wall of blast furnace and roller could increase mechanical properties of central area and casting yield
文摘:利用江西省丰富的钇基重稀土,结合镁、钡、硅、钙等元素的特性开发了钇基重稀土复合球化剂,该球化剂具有脱硫、脱氧、抗干扰元素、球化和抗球化衰退能力强,细化基体组织,白口倾向小,适用范围宽等特点,应用于高炉冷却壁,轧辊等关键铸件上可提高心部力学性能和工艺出品率。
