济南铝板http://www.jngdly.com/在熔炼过程必须有足够高的温度以保证合金铝板等金属元素充分熔化及溶解，加热温度过高，熔化速度增快，同时也会使金属与炉气、炉衬等相互有害作用的时间缩短。生产实践表明，快速加热以加速炉料的熔化，缩短熔化时间，对提高生产率和质量都是有利的。
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.

但是过高的温度容易发生过热现象，特别是在使用火焰反射炉加热时，火炮直接接触炉料，以强热加于熔融或半熔融状态的金属，容易引起气体侵人熔体。同时、温度越高，金属与炉气、炉衬等互相作用的反应也进行得越快，因此会造成金属的损失及熔体质量的降低。过热不仅容易大量吸收气体，而且易使在凝固后铸锭的晶粒组织粗大，增加铸锭裂纹的倾向性，影响合金性能。因此，在熔炼操作时，应控制好熔炼温度，严防熔体过热。
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.

济南铝板在实际生产中，既要防止熔体过热，又要加速熔化，缩短熔炼时间。熔炼温度的控制极为重要。大多数工厂都是采用快速加料后高温快速熔化，使处于半固体、半液体状态时的金属较短时间暴露于强烈的炉气及火焰下，降低金属的氧化、烧损和减少熔体的吸气。当炉料化平后出现一只层液体金属时，为了减少熔体的局部过热，应适当地降低熔炼温度，并在熔炼过程加强搅拌以利于熔体的热传导。
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.
