结构钢板强度变化与材料规格代用的分析

Analysis of Structure Armor Plate Strength Changes and Material Specification Substitutes

锅炉钢结构中,钢板厚度变化影响材料强度。以柱底板为例,详细论述了在计算中,钢板厚度处于相应材料厚度范围临界值时,由于材料强度随板厚变化而变化,当材料计算厚度向上圆整或在生产制造中以厚板代用薄板时,材料强度会降低,会出现虽然钢板厚度增加但强度却不能满足受力要求的特殊现象。

Introduces the effect of thickness change of armor plate on material strength in boiler steel structure. Detailed presents the yield strength of the material will change according to the thickness when the design thickness is at critical value of the material thickness. When material account thickness tidy up or in the making thick armor plate cover for thin armor plate, material strength will be debased, although armor plate aggrandize thickness intension is not content to load.
