冷拔圓鋼對殘余應(yīng)力產(chǎn)生的原因。均勻變形：塑性變形后，載荷去除后內(nèi)部由于變形構(gòu)成的應(yīng)力;熱效果：簡單舉例：冷拔圓鋼冷卻進(jìn)程中外部冷卻快，內(nèi)部冷卻慢，因而外部出現(xiàn)拉應(yīng)力，內(nèi)部出現(xiàn)壓應(yīng)力狀況;還有由于相變等等原因發(fā)生的熱殘余應(yīng)力?；瘜W(xué)效果發(fā)生的應(yīng)力。冷拔圓鋼殘余應(yīng)力的測驗(yàn)方法，需要依據(jù)的推理來決定，當(dāng)然通過對切取部分變形量進(jìn)行測量，可反推出殘余應(yīng)力的大小。這也是殘余應(yīng)力測驗(yàn)的方法。更多關(guān)于冷拔圓鋼的資訊，可以查看康弘機(jī)械官網(wǎng)。新鄉(xiāng)冷拔異型鋼專業(yè)生產(chǎn)廠商</p><p
