应用自行研制的控制冷却热处理装置，研究了小直径锚杆的控冷热处理工艺。结果表明，在实验范围内，控冷热处理工艺参数（ｐ／ｖ）对小直径锚杆体的强度和塑性有显著影响。适当的ｐ／ｖ值，可使φ１２锚杆的拉伸性能达到φ１６锚杆的性能。在实验基础上，分析了锚杆控冷强化的机理及控冷工艺参数对锚杆性能的影响，为煤矿巷道支护改革提供实验和理论依据。 The self-developed controlled cooling heat treatment device was used to study the controlled cooling and heat treatment process of the small diameter anchor rod. The results show that the controlled cooling and heat treatment process parameters (p / v) have a significant effect on the strength and plasticity of the small diameter anchor rod body in the experimental range. Appropriate p / v value, φ12 bolt tensile properties up to φ16 bolt performance. On the basis of experiments, the mechanism of cold-hardening of anchor rod and the influence of controlled cooling process parameters on the performance of anchor rod were analyzed, which provided experimental and theoretical basis for coal mine roadway support reform.
