Because consumption of acid, solvent and zinc is related to and calculated by pipe’s surface area, production data should include both weight yield and area yield.四．試生產(chǎn)說明 Startingup illustration Galvanizing furnace ignition and heating up 在鋅鍋內(nèi)碼放好鋅錠與鉛錠后可進(jìn)行點(diǎn)火,高爐煤氣熱值極低,續(xù)燃能力差,較難點(diǎn)火. ”（？）鋼管組成的燃燒器作為輔助火源進(jìn)行點(diǎn)火。Piled zinc and lead ingots, and use a piece of rubber tube and meter long steel pipe as a auxiliary burning device to ignite the main fire, because blastfurnace gas has low calorific value and is hard to light up. 點(diǎn)火前應(yīng)準(zhǔn)備8套燃燒器對(duì)8套燒嘴同時(shí)進(jìn)行強(qiáng)迫點(diǎn)火。Prepare 8 sets of burning device to light 8 burners simultaneously. 由于鍍鋅爐在此之前曾經(jīng)過水，但時(shí)間已過去45個(gè)月估計(jì)已自然風(fēng)干。但為保險(xiǎn)起見，升溫時(shí)擬適當(dāng)延緩升溫梯度，并適當(dāng)增加110℃區(qū)（顯含水的蒸發(fā)）及300℃區(qū)（結(jié)晶水的去除）的保溫時(shí)間以期爐體安全渡過升溫期。The furnace might have been contacted with water and got dry after 45 months exposure to air. But still for sake of safety, laggard and placid heating speed is remended, elongate time at temperature of 110℃(flowing water evaporation) and 300℃(crystal water evaporation).
