JXHAC坩埚使用及保养方法

Crucible Care and Use

坩埚应存放在温度干燥的场所

Store crucibles in a dry, warm area.

坩埚不能相嵌放置

Do not stock inslde another.

不要直接滚动坩埚

Do not roll crucibles.

应该用耐火毡密封,坩埚两侧需留有膨胀间隙

Use a Ceramic fiber Blanket to seal. allow space between top and sides of furnace

在倾斜炉中应使用定位砖块,以利于坩埚受热膨胀

Use locating bricks in tilting furnaces,to allow for expansion.

火焰加热应与坩埚臂呈切线方向,环绕在坩埚周围

Tangential fire around Crucible.

仅当金属熔化后才可加入添加剂

Only add flux after metal is molten

确保使用时紧急排放孔已经密封,以防坩埚过早氧化失效

Avoid premature crucible failure by ensuring that the furnace drain hole is sealed.

坩埚吊出时,夹具应夹持在坩埚底部1/3处,且两侧均有受力

For lift-out,tongs must be placed on lower third of crucible fit tongs evenly on both sides.

使用前仔细检查有无裂缝和运输时造成的其他损失

Check for cracks or transport damage before use.

坩埚底座应平整,略大于坩埚底部,且安装必须对中

Base block must be fiat ,larger than crucible bottom and centered.

加料时应该使用夹具轻拿轻放,避免直接将料投入坩埚内

Ingots should be placed carefully into the cruible,using tongs.

坩埚从炉体移出前必须清空,切勿使用金属液在坩埚内凝固

Empty curcible before removing from furnace.Do not let metal Solidify in crucible

应每日趁热将坩埚清理干净

Clean carefully everyday while still hot.

先加入一些小块的回料,在将锭料竖直加入坩埚内

Put in returns scrap first. then add ingots vertically

JXHAC坩埚预热使用说明

Crucible Heating Recommendation


坩埚首次使用遇热曲线线


坩埚再次使用之后预热曲线

首次使用坩埚预热具体步骤如下:

1.首先在两个小时之内将坩埚缓慢加热到200度,除去坩埚内可能存在的潮气

2.随后缓慢升温,在1.5小时后达到600度,以使坩埚表面的图层充分烧结,防止坩埚氧化,最大程度的提高坩埚使用寿命。

3.最后 用半小时全功率加热到920C 保温一个小时 然后加料。

4.加热曲线如图中绿线所示。

Preheating Process for Crucible First Use:

1.First,after installation in the furnace the crucible should be heated up slowly to a temperature of 200C over a period of 2 hours,in order to eliminate any moisture that may be present.

2.Subsequently,the crucible should be heated up to 600 C on low power over a period of 1.5hours,to ensure the glaze and crucible material can be sintered and formed into aadditional anti-oxidation coating,which is essential to achieve the maximum possible crucible life.

3.Finally,the full heating rate is used to reach 920C over halt hour, the temperature of 920 C should be held for approximately 1 hour,then add the ingots into crucible.

4.preheating curve as shown in the Green line.

再次使用坩埚遇热具体步骤如下:

1.首先,在两个小时之内缓慢加热坩埚600C,以达到去除坩埚内存在的潮气与使坩埚表面涂层充分烧结,防止坩埚氧化的目的

2.随后,继续加热,在半小时之内加热到920,保温一个小时,然后加料。

3.加热曲线如图中红线所示。

Preheating Process for Crucible After First Use:

1.First,the crucible should be heated up slowly to a temperature of 600 C over a period of 2hours, in order to eliminate any moisture that may be present and to ensure the glaze and crucible material can be sintered to avoid the crucible material be oxidized.

2.subsequently,the full heating rate is used to reach 920 C over half hour,the temperature of 920c should be held for approximately 1 hour,then add the ingots into crucible.

3.Preheating curve as shown in the Red line.
