摘 要：某公司淬火爐因燃?xì)夥N類變化對燃燒系統(tǒng)進(jìn)行了改造，改造后出爐溫度命中率波動較大，嚴(yán)重影響了產(chǎn)品性能的穩(wěn)定性。通過對出爐溫度命中率主要影響因素的分析，從點(diǎn)火電極的陽極與陰極之間距離變化、UV探頭失效分析及內(nèi)外溫差導(dǎo)致燒嘴損壞三個方面提出了解決方案，實(shí)現(xiàn)了出爐溫度命中率的大幅提升。

Abstract：The combustion system of a company quenching furnace is transformed according to the change in the gas type， the large fluctuation of heating temperature hit rate was found after transforming， seriously affect the stability of product performance. In this paper， through analysis of the main factors that influence heating temperature hit rate，the solutions are put forward from three aspects： distance change between the anode and cathode of ignition electrode，failure analysis for UV detector and burner damage caused by temperature difference between inside and outside， realized that the hit rate of heating temperature increase greatly.

Key words： heating temperature hit rate; burner; UV detector

某公司為了大力推進(jìn)綠色循環(huán)經(jīng)濟(jì)、節(jié)約生產(chǎn)成本，對現(xiàn)有中厚板淬火爐進(jìn)行改造，充分利用自產(chǎn)高爐、轉(zhuǎn)爐煤氣以替代商采天然氣，混合煤氣噸鋼燃料成本比天然氣要低70元左右，但是燃?xì)鉄嶂涤? 000 kcal/Nm3降低至2 200 kcal/Nm3。（剩余3683字）
