濟(jì)南鋁板http://www.7075lu.com/在熔煉過程必須有足夠高的溫度以保證合金鋁板等金屬元素充分熔化及溶解，加熱溫度過高，熔化速度增快，同時(shí)也會(huì)使金屬與爐氣、爐襯等相互有害作用的時(shí)間縮短。生產(chǎn)實(shí)踐表明，快速加熱以加速爐料的熔化，縮短熔化時(shí)間，對(duì)提高生產(chǎn)率和質(zhì)量都是有利的。
Jinan aluminum smelting process must have a sufficiently high temperature to ensure that aluminum alloy and other metal elements melting and dissolved sufficiently, the heating temperature is too high, the melting speed faster, but also make mutual harmful action metal with the furnace gas, lining and so reduce the time . Practice shows that rapid heating to accelerate the melting charge,shorten the melting time, to improve productivity and quality are beneficial.

但是過高的溫度容易發(fā)生過熱現(xiàn)象，特別是在使用火焰反射爐加熱時(shí)，火炮直接接觸爐料，以強(qiáng)熱加于熔融或半熔融狀態(tài)的金屬，容易引起氣體侵人熔體。同時(shí)、溫度越高，金屬與爐氣、爐襯等互相作用的反應(yīng)也進(jìn)行得越快，因此會(huì)造成金屬的損失及熔體質(zhì)量的降低。過熱不僅容易大量吸收氣體，而且易使在凝固后鑄錠的晶粒組織粗大，增加鑄錠裂紋的傾向性，影響合金性能。因此，在熔煉操作時(shí)，應(yīng)控制好熔煉溫度，嚴(yán)防熔體過熱。
But the high temperature prone to overheating, especially in the use of flame reverberatory furnace heating, gun charge in direct contact to the intense heat is applied to the molten or semi-molten metal, prone to gas invasion melt. Meanwhile, the higher the temperature, the reaction interact with the metal furnace gas, the lining also be faster, it will cause metal loss and decrease melt quality. Superheated gas absorbs not only easy, but also easy to make the grain structure in the solidified ingot thick, increasing propensity ingot cracks Alloy. Therefore, in the smelting operation, should control the melting temperature of the melt to prevent overheating.

濟(jì)南鋁板在實(shí)際生產(chǎn)中，既要防止熔體過熱，又要加速熔化，縮短熔煉時(shí)間。熔煉溫度的控制極為重要。大多數(shù)工廠都是采用快速加料后高溫快速熔化，使處于半固體、半液體狀態(tài)時(shí)的金屬較短時(shí)間暴露于強(qiáng)烈的爐氣及火焰下，降低金屬的氧化、燒損和減少熔體的吸氣。當(dāng)爐料化平后出現(xiàn)一只層液體金屬時(shí)，為了減少熔體的局部過熱，應(yīng)適當(dāng)?shù)亟档腿蹮挏囟龋⒃谌蹮掃^程加強(qiáng)攪拌以利于熔體的熱傳導(dǎo)。
Jinan aluminum in actual production, it is necessary to prevent overheating of the melt, but also to accelerate the melting, melting time shorter. Control the melting temperature is extremely important. Most plants are using flash after feeding high-temperature rapid melting, so that in a semi-solid, semi-liquid state of metal shorter time when exposed to intense flame furnace gas and reduce the oxidation of the metal, burning and reduce melt suction gas. When a layer of liquid metal after the charge level, in order to reduce local overheating of the melt should be appropriate to reduce the melting temperature, and to strengthen the agitation in order to facilitate the melt in the smelting process of heat conduction.
