江西省砖瓦行业中,焙烧窰一般的都是以轮窰,土窰、马蹄窰为主,一九五六年为了保证供应基建需要,推行了一种“日式窰”(实际上是一种改良后的土窰)生产红砖,获得良好的效果。它有如下几点优点:(一)生产出来的产品颜色很均匀,规格较一致,成品率高达99—100%。其抗压强度经试验平均达146公斤/平方公分,最高达180公斤/平方公分;(二)建造简单,没有窰顶。窰墙、窰床、(?)条全部是用砧或废
In the brick and tile industry in Jiangxi Province, roasters are generally based on wheel kiln, earth kiln, and horseshoe kiln. In order to ensure the supply of infrastructure in 1956, a kind of “kiln kiln” was implemented (actually It is an improved earth kiln to produce red bricks and get good results. It has the following advantages: (1) The color of the products produced is uniform and the specifications are relatively uniform. The finished product rate is as high as 99-100%. Its compressive strength has reached an average of 146 kg/cm ^ 2 and has reached a maximum of 180 kg/cm ^ 2; (2) The construction is simple and there is no kiln roof. Kiln walls, kiln beds, (?) strips are all anvil or waste
