In the present paper, the finite element method was used to calculate casting iridium crucible temperature field of three samples.

摘 要：为了克服传统Ir坩埚铸造研究中需占用大量Ir和资金的缺点，作者采用有限元方法计算了3种不同尺寸的Ir坩埚在铸造过程中的温度场变化特点。

The detailed procedures of the method are as follows: the charging material of Ti-6Al-4V alloy is put into the crucible of an induction skull melter, heated and melted under the environment of high-purity argon and 400-700Pa pressure; pre-coated bars with the TiH2 of the weight accounting for 0.09 to 0.2 percent of the charging material are added in; when the hydrogen-contained titanium alloy in the crucible cools and the temperature drops below 300 DEG C, the charging material is vented off and cooled until the temperature equal to room temperature.

它的具体方法为：将Ti-6Al-4V合金的炉料装入感应凝壳熔炼炉的坩埚中，在压力为400～700Pa的高纯氩气环境中进行加热熔化；然后熔入含炉料质量0.09％～0.2％的TiH2的预制棒；当坩埚中含氢的钛合金逐渐冷却凝固并降温至300℃以下后，破真空，进一步冷却至室温。

Design development aluminum casting profession centralized melting furnace, energy conservation coal gas pot furnace, electric heating pot furnace; The aluminum T-6 heat treatment line, the aluminum fluid low temperature fuse technology after the aluminum profession success application, receives the user high praise.

设计开发铝铸造行业的集中熔化炉，节能煤气坩埚炉，电热坩埚炉；T-6热处理线，铝液低温熔解技术在铝行业成功应用后，受到用户好评。

Company produces the "Tianfu card" graphite crucible, from 0.5 #-2000 #, model specifications, and supporting the production of graphite core reverberatory furnace crucible, graphite ring, graphite plate, and in accordance with the requirements of users profiled the production of graphite products .

First, some critical problems in crystal growth like crystal seeding, Zn dephlegmation, geometrical selection and temperature fields are discussed in theory, and the possible kinds of defects appeared in crystal growth progress and the reasons are carefully researched. To control the concentration of Cd vacancies, a new method by which the Cd vacancies were compensated with excess Cd in the Cd rich starting materials has been developed, and a new kind of two-area tube furnace with good linear temperature distribution was designed.

首先，本文从理论上对坩埚下降法生长碲锌镉单晶体中的成核、Zn分凝、几何淘汰生长与温场等关键性问题进行了讨论，对在生长过程中可能出现的各种缺陷类型和形成原因进行了详细分析，提出了碲锌镉单晶体生长过程中Cd空位缺陷控制原理及方法，并针对坩埚下降法生长特点自行设计了两区域独立加热管式生长炉，获得具有较好线性分布的温场。

Experimental conditions were: two equiponderant crucibles, 3~5mg equiponderant writing and blank paper, static air, heating rate 10℃/min, relative age between 2 days and 5 years.

特征峰出现的条件为：等重的字迹和空白纸分别置于2个等重的坩埚；以装有空白纸的坩埚作为参比；实验气氛为静态空气；升温速率10℃/min；字迹书写后存放时间为2~365×5d。

The lining is an unsealed copper ring; the section of the lining inner cavity is a ladder cavity, the bottom is equipped with an edge shaped via enclosing a crucible; the heating coil is silverly welded in the arc groove of the cylindrical surface of the lining, and the upper of the lining winds a few turns coil around the center of the crucible; the two ends of the composite induction heating device are accessed to a high frequency induction power respectively.

内衬(11)为未封闭铜圆环；内衬内腔的剖面为梯形空腔，底部有装入坩埚(4)的刃形通孔(12)；加热线圈(10)银焊在内衬外圆表面的弧形凹槽中，并在内衬(11)上方以坩埚(4)为中心绕制数匝线圈；将复合感应加热装置(5)的两端分别接入高频感应电源(9)。
