The present invention relates to a kind of bronze ingot. It is characterized by the composition of the following weight percentage: Tin 6 - 7%, phosphorus 0.1 - 0.25%, copper allowance. It is characterized by the composition of the following weight percentage: tin 7%, phosphorus 0.2%, copper 92.8%. A method for the production of bronze ingot is characterized as: first, the copper is thrown into the furnace, the ignition is heated to 1080~1100 degree, and the charcoal is added to the smelting. Then the tin and phosphorus are put into the smelting furnace to continue the smelting temperature to 1080~1150 degrees, and the temperature is raised to 1180~1240 degrees after the smelting, and the horizontal continuous casting method is adopted after the furnace is released. The casting of the bronze ingot. It is characterized by charcoal generally covering 8~10 cm of copper water surface. The advantage of the invention is to use the Spike direct reading spectrometer in Germany to make a full analysis of the copper water before the smelting of the ingots, and to recheck the standard samples by atomic absorption spectrophotometer to ensure that the composition of the copper water is fully qualified and the composition is accurate.

一种青铜锭的生产工艺
本专利技术涉及一种青铜锭。
技术介绍
青铜锭广泛用于铸造行业,用于翻沙、铸造阀门配件、涡轮涡杆、轴瓦滑块等。目前多采用半连续铸造方式,生产各种规格铸锭,产品成材率较低,且锭材表面较粗糙,易发生反偏析。因此亟待对有现有的青铜锭进行改进,以解决目前青铜锭所存在的问题。
技术实现思路
本专利技术的目的是解决现有技术中青铜锭所存在的上述问题,提供一种青铜锭。本专利技术设计一种青铜锭,其特征在于由下列重量百分比的组成物组成:锡6——7%,磷0.1——0.25%,铜余量。其特征在于由下列重量百分比的组成物组成:锡7%,磷0.2%,铜92.8%。一种青铜锭生产方法,其特征在于:先将铜投料到炉子里,点火加热到1080~1100度,加入木炭进行冶炼,然后再将锡、磷放入冶炼炉中继续冶炼温度升到1080~1150度,炼后温度升到1180~1240度后出炉,出炉后采用水平连续浇铸法进行青铜锭的浇铸。其特征在于:木炭一般以覆盖铜水表面8~10公分。本专利技术的优点是采用德国产斯派克直读光谱仪,对熔炼引锭前的铜水进行全分析,而且采用原子吸收分光光度计对标样进行复检,确保了铜水成份完全合格,成份准。下面结合实例对本专利技术作详细使用说明。具体实施方式一种青铜锭,其特征在于由下列重量百分比的组成物组成:锡6——7%,磷0.1——0.25%,铜余量。其特征在于由下列重量百分比的组成物组成:锡7%,磷0.2%,铜92.8%。一种青铜锭生产方法,其特征在于:先将铜投料到炉子里,点火加热到1080~1100度,加入木炭进行冶炼,然后再将锡、磷放入冶炼炉中继续冶炼温度升到1080 ...
