The fracture reasons of high strength PC steel wire are analyzed, it's considered that center segregation, central cavitation, poriness and inclusion are the metallurgical reasons which lead to the facture of PC steel wire and in the rolling process, differential coping quality, microcrack caused by surface defect, abnormal microstructure caused by burnt and improper cooling velocity, the ears on the head of the wire, overlapping of the wire rod itself are the main reasons which lead to the facture of PC steel wire. At the same time, inappropriate pickling, differential phosphorization quality, the bad heat treatment quality, the generation of crack in the improper drawing and transverse crack caused by abnormal laying of the drawing die are also the reasons of the cracking of PC wire.

对高强度PC钢丝断裂原因进行了分析，认为连铸坯的中心偏析、中心缩孔、疏松和夹杂是导致PC钢丝断裂的冶金原因；轧制过程中，较差的修磨质量、表面缺陷导致的微裂纹，过烧以及不适当的冷却速度导致的非正常显微组织，盘条头部的耳子、盘条本身折叠是导致PC钢丝断裂的主要原因；同时，不恰当的酸洗、较差的磷化及热处理质量、不适当拉丝裂纹的产生、拉拔模具安放不正导致的横裂也是PC钢丝断裂的原因。

The technique comprises the steps as follows: using the waste filtered mud of the sugar-refinery as the material to generate gas which is dehydrated till the water content is less than and equal to 30 percent and through distribution (clay used for of 70.00 to 85.0 percent, dehydrated filtered mud of the sugar-refinery of 15.0 to 30.0 percent, intensifier carboxymethyl cellulose or propyloic fibrin is 0.1 percent of the total dosage of the below material), performaing, moulding with high temperature (800 to 1200 DEG C, 20 to 180min) and acquiring the multi-hole porcelain granule with 20 to 30 percent of poriness, 10 to 20 percent of water absorbing capacity and 1.5 to 7.5/MPa of cylinder pressing intensity.
