坩锅炉是铸造有色合金常用的熔炉。我厂熔炼铜合金和铝合金分别采用焦炭反射炉和燃油坩锅炉。使用这两种炉子时,最常感到头痛的是炉膛和炉盖的接触处常出现喷火现象。原来,我们为防止这种现象,在炉膛和炉盖接触处用耐火泥作垫衬,但长期使用这种方法,一是繁忙,二是浪费很大,每天约需要300公斤左右的耐火泥。 根据生产经验,我们在设计熔炼炉时对炉膛和炉盖作了一定的改进。在炉膛和炉盖接触的相应部位,分别开出宽为60毫米的圆环形槽。炉盖
Crucible boiler is commonly used for casting non-ferrous alloy furnace. Our factory smelting copper alloy and aluminum alloy were used coke furnace and fuel crucible boiler. The most common headache when using both types of furnaces is the fact that there is often a spit fire at the point of contact between the hearth and the lid. Originally, in order to prevent this phenomenon, we used refractory mud to make linings at the contact between the furnace and the furnace cover. However, this method has been used for a long time. One is that it is very busy and the other is very wasteful. It takes about 300 kilograms of refractory clay every day. According to the production experience, we made some improvement on the furnace and the furnace cover when designing the melting furnace. In the furnace and the furnace cover the corresponding parts, respectively, out of wide circular groove 60 mm. Hearth
