烧结矿的常温机械强度是烧结矿的一项重要物理性能。是评价烧结矿成品在从烧结厂到装入高炉的转运过程中,经受因碰撞、磨擦、挤压等所产生的破碎、磨擦能力的一项重要指标。烧结矿机械强度通常用转鼓试验法检验。因此,转鼓试验法标准的制订和统一对推动我国烧结生产、试验研究,以及技术交流都具有一定的重要意义。 The mechanical strength of sinter at room temperature is an important physical property of sinter. It is an important index to evaluate the ability of sinter finished products to be crushed and rubbed due to collision, friction and squeezing during the transportation from sinter plant to blast furnace. Sinter mechanical strength is usually tested by drum test method. Therefore, the formulation and unification of drum test standards have a certain significance for promoting the sinter production, experimental research and technological exchanges in our country.
