因为铅扳在室温下是属于热加工， 铅扳加工硬化的同时伴随回复和再结晶过程。 铅扳越弯越硬是由于位错大量增加而引起的加工硬化造成， 而过一段时间又会变软是因为室温对于铅扳已经是再结晶温度以上，所以伴随着回复和再结晶过程，等轴的没有变形晶粒取代了变形晶 粒，铅扳硬度和塑性又恢复到了未变形之前。铅板具有很强的防腐蚀，耐酸碱，耐酸环境施工、医用防辐射，X光，CT室射线防护、加重、隔音等许多方面，而且是一种比较廉价的防辐射材料。

铅玻璃在熔断时有哪几种方法？
　　熔炼铅玻璃离不开高温窑炉,铅玻璃熔窑有许多种,有烧煤气或天然气的,有烧油的,有电加热的.综述起来主要有三种熔断方式.

　　Smelting lead glass can not be separated from the high temperature furnace. There are many kinds of lead glass furnaces, such as burning gas or natural gas, burning oil and electric heating. There are mainly three ways of fusing

　　1、坩埚：一些铅玻璃和特殊光学玻璃是用坩埚窑来熔炼的,所说的坩埚就是耐火材料做的容器,外形有的象水壶,有的象短粗的杯子,将它们放置在高温窑炉中,烧得通红,再将原料加在里面.

　　1, lead glass and Crucible: some special optical glass is used to smelting crucible kiln, the container is made of refractory crucible, shape like kettle, some like a cup, placing them in the furnace, burned red, and then added to the raw materials inside.

　　2、玻璃液：在坩埚中原料发生各种高温化学变化,剧烈地沸腾着,放出很多气体,最后就"安静"下来了,变成了又浓又稠,软软的,就象刚刚熬好的麦芽糖一样的液体,这种液体叫做玻璃液.

　　2, glass melt in the crucible material: all kinds of high temperature chemical changes, violently boiling, emit a lot of gas, finally quiet down, turned into a thick, soft, just like cooked maltose as liquid, this liquid is called liquid glass.

　　3、实际生产：上面提到的坩埚炉容量小,供不上机械化生产的需要,所以在机械化生产中,玻璃都是在池炉中熔炼的.原料从用耐火砖砌的很大的池子的一端源源不断地加进去,熔炼好了的玻璃液从另一端源源不断地滴下来;滴到机器中去成型.池炉比坩埚可要大多了,有的池炉竞有一个小型的游泳池那样大,里面能容纳上千吨的玻璃液.玻璃液的温度很高,如果冷下来,就会凝固,所以要想将玻璃加工成一定的形状,就必须趁热制作。

　　3, the actual production capacity: crucible furnace mentioned above, not on the need for the mechanization of production, so in the mechanization production, glass melting furnace is in the pool. The raw material from one end of firebricks large pool of Everfount added, glass melting well from the other one end of Everfount trickle down; drop into the machine to molding. Furnace crucible can be bigger than, some competitive furnace has a small swimming pool as big, can accommodate thousands of tons of liquid inside the glass. The glass liquid temperature is very high, if the cold will solidify, so down to glass processing into a certain shape, it must take advantage of heat production.
