熔煉鉛板離不開高溫窯爐,鉛板熔窯有許多種,有燒煤氣或天然氣的,有燒油的,有電加熱的.綜述起來主要有三種熔斷方式.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坩堝：一些鉛板和特殊光學(xué)玻璃是用坩堝窯來熔煉的,所說的坩堝就是耐火材料做的容器,外形有的象水壺,有的象短粗的杯子,將它們放置在高溫窯爐中,燒得通紅,再將原料加在里面.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.
玻璃液：在坩堝中原料發(fā)生各種高溫化學(xué)變化,劇烈地沸騰著,放出很多氣體,最后就"安靜"下來了,變成了又濃又稠,軟軟的,就象剛剛熬好的麥芽糖一樣的液體,這種液體叫做玻璃液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.
實(shí)際生產(chǎn)：上面提到的坩堝爐容量小,供不上機(jī)械化生產(chǎn)的需要,所以在機(jī)械化生產(chǎn)中,玻璃都是在池爐中熔煉的.原料從用耐火磚砌的很大的池子的一端源源不斷地加進(jìn)去,熔煉好了的玻璃液從另一端源源不斷地滴下來;滴到機(jī)器中去成型.池爐比坩堝可要大多了,有的池爐競(jìng)有一個(gè)小型的游泳池那樣大,里面能容納上千噸的玻璃液.玻璃液的溫度很高,如果冷下來,就會(huì)凝固,所以要想將玻璃加工成一定的形狀,就必須趁熱制作。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.
