【摘要】 刮板输送机是煤矿运输的主要设备,中部槽槽帮是刮板输送机向前移动的主要受力部位,其质量将影响刮板输送机运行及煤矿的正常安全生产。本文针对影响中部槽槽帮质量的两个重要因素——化学成分和热处理对ZG30MnSi槽帮钢力学性能的影响进行研究,以期通过优化化学成分配比和热处理工艺达到进一步提高中部槽槽帮质量的目的。本文采用正交试验设计法,对不同碳、锰、硅、铝含量的ZG30MnSi槽帮钢试样、对不同正火处理、不同调质处理的ZG30MnSi槽帮钢试样进行力学性能试验,得出试验结果。对试验结果分析研究,得出以下几点:(1)碳、锰、硅、铝含量对ZG30MnSi槽帮钢力学性能的影响及最佳的成分配比。(2)正火加热温度对ZG30MnSi槽帮钢力学性能的影响及最佳的正火加热温度。(3)调质淬火加热温度和回火加热温度对ZG30MnSi槽帮钢力学性能的影响及最佳的调质工艺。本文针对化学成分和热处理对ZG30MnSi槽帮钢力学性能影响的研究结论的应用将使槽帮钢质量进一步提高,同时进一步提高了刮板输送机的整体使用性能。更多还原

【Abstract】 Scraper conveyor is the main equipment of coal transport,the central groove edge is scraper conveyor main stress move parts,its quality will affect scraper conveyor operation and coal mine’s normal safety in production. Aiming at the impact the quality of central groove edge two important factors - chemical composition and heat treatment ZG30MnSi slot on the mechanics properties of edge steel was studied,in order to optimize chemical composition ratio and by heat treatment process as to further improve the quality of groove side of central purpose.This paper adopts the method of orthogonal test design,for different carbon, manganese, silica and alumina content of ZG30MnSi slot edge steel specimens,for different normalizing processing, different the quenching and tempering treatment ZG30MnSi slot edge steel specimen mechanical test,draw test results.Analysis and research on test results, some conclusions:(1) The effect of ZG30MnSi slot edge steel mechanical properties about carbon, manganese, silica and alumina content;The best chemical composition ratio of ZG30MnSi slot edge steel.(2)The effect of ZG30MnSi slot edge steel mechanical properties about normalizing heating temperature;The best normalizing heating temperature of ZG30MnSi slot edge steel. (3)The effect of ZG30MnSi slot edge steel mechanical properties about hardened heating temperature and Piece.modified tempering tempering heating temperature;The best hardened heating temperature and Piece.modified tempering tempering heating temperature of ZG30MnSi slot edge steel.This paper ZG30MnSi heat treatment on the chemical composition and mechanical properties of steel tank side impact study conclusion application,will make further improve steel quality slot edge,and further improve the scraper conveyor’s overall performance.更多还原
