摘要: 從頂頭生產(chǎn)工藝控制的角度,分析了貝氏體鋼內(nèi)水冷穿孔頂頭產(chǎn)生粘鋼的原因、特點(diǎn)和機(jī)制,指出掉鼻、缺肉是頂頭粘鋼的另一種更為嚴(yán)重的失效形式,強(qiáng)化熔煉工藝控制和保證夾雜物總量在A0.5B1C0.5D1級(jí)水平,粘鋼問題可以得到有效控制。Abstract: From the point of view of plug manufacturing process control, the co-authors discuss the causes, characteristics and mechanism of steel pick-up of the internally water-cooled bainite steel piercing plug, emphasizing that plug pointed end collapse and spot metal-losing are more serious forms of failure. Actions to effectively control the said steel pick-up problem include intensifying control of melting process and keeping the total inclusion content at the level of Class A0.5B1C0.5D1.
