谁能帮我翻译成英语，必有重谢！

本设计是针对一汽集团的国产奥威卡车十字轴的材料选择及热处理工艺的初步设计，力求对所学专业知识和专业技能，进行一次综合训练。
通过对奥威十字轴的具体服役分析，知道其主要的失效形式磨粒磨损、疲劳磨损、氧化磨损和冲击载荷破坏。根据服役分析的结果，对其做出合理的硬度、强度、塑性、耐磨性、韧性等力学性能要求。
依据性能要求，选择若干种具体牌号的渗碳钢、感应加热淬火表面硬化钢，并对其参数比较分析，最终选择20CrMoH作为奥威十字轴用钢。
根据十字轴性能要求及选择的材料，结合一汽集团锻压和热处理分厂的实际加工工艺。确定加工工艺为下料→毛坯成型→预备热处理→粗加工→清洗喷丸→最终热处理→精加工。加工工艺着重说明了预备热处理工艺和最终热处理工艺，合理确定预备热处理和最终热处理的具体工艺时间、温度、保温方式、冷却介质等参数。
完成设计所需的加热、保温、冷却以及辅助设备额选择。简要作出热处理操作的必要注意事项。

关键词：十字轴；20CrMoH；硬度；磨损；耐磨性；冲击载荷；热处理工艺

Answer 1

This design is for the FAW Group of China-made cars Aowei Ka cross-axis of material selection and preliminary design of the heat treatment process, to the school by the professional knowledge and professional skills, to conduct a comprehensive training.
Through the cross-axis Aowei analysis of the specific service, that the failure of its main form of abrasive wear, fatigue and wear, wear and impact load of damage. According to the analysis of the results service, its reasonable to make the hardness, strength, plastic, wear resistance, toughness and other mechanical performance requirements.
Basis performance choose several specific Grades Carburizing steel Induction Heating Quenching surface hardening steel and its parameters comparative analysis finally selected 20 CrMoH Aowei Cross as steel shaft.
According to cross-axis performance requirements and the choice of materials, with the FAW Group forging and heat treatment plant of the actual processing technology. Identify materials processing technology for the next preparatory → rough forming → heat treatment → rough → clean shot peening → → finishing the final heat treatment. Processing technology focused on the preparatory heat treatment process and the final heat treatment process, heat treatment and prepared to rationally determine the final heat treatment of the specific time, temperature, thermal insulation, such as the cooling medium parameters.
Complete the design for heating, insulation, cooling and auxiliary equipment of choice. Summary heat treatment to make the necessary attention to matters of operation.

Key words: Cross-axis; 20 CrMoH; hardness; wear; wear resistance, impact load; heat treatment process
