用碳化麦杆麦壳做金属液面保温剂的试验研究

STUDY ON USING CARBONIZED WHEAT STRAW ANDHUSK AS INSULATION OF LIQUID METAL

对碳化麦杆麦壳的理化性能和保温性能在实验室进行了试验研究。研究结果表明，碳化麦杆麦壳与碳化稻壳具有相同的保温性能，因此用碳化麦杆麦壳代替碳化稻壳作为金属液面保温材料是完全有可能的，这对因地制宜开发我国丰富的麦杆麦壳资源有着重要的意义。

This paper gives a systematic account of the physicochemical and insulation properties of carbonized wheat straw and huskBased on the experiments in the laboratory,it is shown that carbonized wheat straw and husk possess the same insulating properties as carbonized rich huskTherefore,it is quite possible to replace the latter with the former as insulating material for liquid metalThis practice,which suits the concrete conditions in north part of China,is of considerable practical importance in the exploitation of abundant resources of wheat straw and husk
