日标方矩管：实验结果分析膨润土配比为0.8%时，基准样落下强度为4.7次/个（该强度已不能满足生产要求）。而赤铁矿粉分别配入15%、20%时，落下强度分别为6.5次/个和8.2次/个，配入20%时已高出生产时对该强度指标的要求。这说明还有进一步降低膨润土用量的可能。由于赤铁矿粉粒度较细，-200目达96%，从检测结果看，分别为550℃和630℃而基准样为700℃。配入赤铁矿粉后，粒度变细，成球时吸水量增加，受脱水速度的影响爆裂温度有所降低。

日标型钢：
一般油淬火后工件是银灰色，盐淬火后蓝褐色。外观不好一般表现有：花脸，花斑，生锈，颜色不正等。花脸：前清洗不干净，炉压低，流量过大，含水，氮气纯度差，油淬下料口密闭性差，炉体局部漏气。花斑：前清洗不干净，流量过大，油淬下料口密闭性差，油幕帘不好，炉体局部漏气，盐槽上部积盐，盐中杂质。生锈：碳势（氧势）过高，炉内积碳，后清洗防锈性差。关于SEP152SEP152是德国的标准，目前在欧洲大多使用该标准，用于评价碳化物的组织，只有标准图片及检验方法，无判定界限；一般情况5与退火有关，基本与淬火无关。
