我厂为适应生产的需要,搞了一台简易铸型干燥炉,很有实用价值,现介绍如下。简易铸型干燥炉如图1所示,它由燃烧室炉基、炉体及烟道闸板控制装置三部分组成。燃烧室炉基用普通的砖石材料及少量的耐火砖砌制而成(见图2)。炉体由金属壳架和敷设在内壁上的硅酸铝纤维板组成,选用的硅酸铝纤维板越厚,其保温性能越好,一般可选用厚度为40～50毫米的硅酸铝纤维板。炉体的形式在一般使 I plant to meet the needs of production, engage in a simple mold drying furnace, very practical value, are presented below. Simple mold drying furnace shown in Figure 1, which consists of the combustion chamber furnace, furnace and flue gate control device consists of three parts. The furnace base is made of ordinary masonry material and a small amount of refractory bricks (see Figure 2). The furnace body is composed of a metal shell frame and an aluminum silicate fiber board laid on the inner wall. The thicker the aluminum silicate fiber board is used, the better its heat insulating property is. Generally, the aluminum silicate fiber board with the thickness of 40 to 50 millimeters can be selected. The form of the furnace is made in general
