1.碎铁的损耗原因有以下几点:(1)铁水流入铁斗(铸铁模)时一部分从铁斗缝溢出流到履带下收集碎铁的簸箕中叫“簸箕碎铁”,占碎铁总量的70%左右。(2)冷却前铁模内晃出的铁水叫“冷却前碎铁”,约占总量的3%。(3)在喷水过程中,铁水呈小铁砂崩出,或在脱模时淌稀叫“冷却中碎铁”,约占2%。(4)铁块在首轮处脱模后掉入吊斗时铁角崩出叫“首轮下碎铁”,约占10%。(5)铁水缸扣渣时,带出一部分铁水和缸圈上带有的碎铁合称“扣缸碎铁”,约占10%以上。(6)跑铁、漏缸等事故损失叫“事故碎铁”,占数量很少。各项碎铁产生的原因及降低损失的措施:(1)簸箕碎铁:其中80%以上是由于轴套磨损斗缝 1. Broken iron loss due to the following points: (1) molten iron into the iron (cast iron mold) part of the overflow from the iron shed to collect the dust under the track to collect iron dustpan called “dustpan broken iron”, accounting for iron About 70% of the total. (2) The molten iron in the iron mold before cooling is called “crushed iron before cooling”, accounting for about 3% of the total. (3) In the process of spraying water, the molten iron is small iron sand collapse, or dripping thin called “cooling iron in the mold”, about 2%. (4) iron block in the first round after stripping fall into the bucket when the iron corner collapse called “the first round of broken iron”, accounting for about 10%. (5) when the iron cylinder buckle slag, bring out part of the molten iron and the ring with a crushed iron collectively known as “buckle broken crushed iron”, accounting for more than 10%. (6) running iron, missing cylinder and other accidental loss called “Accident iron”, accounting for a small number. The causes of the various pieces of iron and reduce the loss of measures: (1) dustpan broken iron: more than 80% of which is due to sleeve wear seam
