扬州SKF轴承余热利用在燃烧炉中已达到较高水平。优化燃烧器结构，严格控制空燃比，在合理燃烧的前提下，使NOx和CO***小化。采用气体渗碳、碳氮共渗和扬州SKF轴承真空热处理代替盐浴处理，将废盐和CN***物质还原为水源。采用水溶性合成淬火油代替部分淬火油。使用可生物降解的植物油代替一些矿物油来减少石油污染。

Yangzhou SKF bearing waste heat utilization has reached a higher level in the combustion furnace. The burner structure is optimized, the air-fuel ratio is strictly controlled, and the NOx and CO are minimized under the premise of reasonable combustion. Using gas carburizing, carbonitriding and SKF bearing vacuum heat treatment instead of salt bath treatment, the waste salt and CN toxic substances were reduced to water sources. Water soluble synthetic quenching oil is used instead of partial quenching oil. Use biodegradable vegetable oil instead of some mineral oil to reduce oil pollution.

（1）废水、废气、废盐、粉尘、噪声、电磁辐射等产生的清洁热处理会污染环境。为了解决扬州SKF轴承热处理引起的环境污染问题，实施清洁热处理（或绿色热处理）是发达***热处理技术的发展方向之一。为了减少SO2、CO、CO2、粉尘和煤渣的排放，煤作为燃料的使用已基本消除，重油的使用量越来越少，大部分扬州SKF轴承轻质油被使用，而***仍是***理想的燃料。

(1) clean heat treatment resulting from waste water, waste gas, waste salt, dust, noise and electromagnetic radiation will pollute the environment. In order to solve the problem of environmental pollution caused by the heat treatment of Yangzhou SKF bearing, the implementation of clean heat treatment (or green heat treatment) is one of the development directi*** of heat treatment technology in developed countries. In order to reduce the emission of SO2, CO, CO2, dust and coal cinder, the use of coal as fuel has been basically eliminated, the use of he***y oil is less and less, most of Yangzhou SKF bearing light oil is used, and natural gas is still the most ideal fuel.

（2）精密热处理精密热处理有两个含义：一方面是基于零件、材料和结构尺寸的要求，通过物理冶金学知识和***的计算机模拟和测试技术对工艺参数进行优化。VE所要求的性能是使材料的潜力***大化；另一方面，扬州SKF轴承优化过程的稳定性得到充分的保证，产品的质量非常小（或零），热处理的变形为零。

(2) precision heat treatment precision heat treatment has two meanings: on the one hand, it is based on the requirements of parts, materials and structure dimensi***, and the process parameters are optimized by physical metallurgy knowledge and advanced computer simulation and test technology. The performance required by VE is to maximize the potential of the material; on the other hand, the stability of the Yangzhou SKF bearing optimization process is fully guaranteed, the quality of the product is very ***all (or zero), and the deformation of the heat treatment is zero.

（3）节能热处理的科学生产和能源管理是能源有效利用的***有潜力的因素。建立***的热处理设备，保证设备的充分生产和充分利用，是科学管理的选择。在扬州SKF轴承热处理的能量结构中，我们选择***种能源，充分利用废热和余热，利用低能耗和短循环技术，不长周期，消耗大量能源。

(3) the scientific production and energy management of energy s***ing heat treatment is the most potential factor for the effective utilization of energy. It is the choice of scientific management to establish professional heat treatment equipment and ensure the full production and full use of the equipment. In the energy structure of Yangzhou SKF bearing heat treatment, we choose the first kind of energy, make full use of waste heat and waste heat, use low energy c***umption and short cycle technology, not long cycle, c***ume a lot of energy.

（4）采用气氛加热代替氧化气氛下的碳势和氮势，采用较少的氧化热处理进行热处理。扬州SKF轴承热处理后，零件性能得到改善。热处理缺陷，如脱碳和裂化，大大减少。减少了热处理后的精整过程的保留，提高了材料的利用率。加工效率。真空加热、气淬、真空或低压渗碳、氮化、氮碳共渗和渗硼可明显提高产品质量，减少变形，延长使用寿命。

(4) using atmosphere heating instead of carbon potential and nitrogen potential under oxidizing atmosphere, heat treatment is carried out with less oxidation heat treatment. After heat treatment of SKF bearing in Yangzhou, the performance of parts has been improved. Heat treatment defects, such as decarbonization and cracking, are greatly reduced. The retention of finishing process after heat treatment is reduced, and the utilization ratio of materials is improved. Processing efficiency. Vacuum heating, gas quenching, vacuum or low pressure carburizing, nitriding, nitrocarburizing and boronizing can ***iously improve product quality, reduce deformation and prolong service life.

扬州SKF轴承零件的热处理质量控制在整个机械行业中是***严格的。轴承热处理在过去20年中取得了很大进展，主要表现在以下几个方面：热处理的基本理论、热处理技术和应用技术的研究、新型热处理设备的开发和相关技术。

The heat treatment quality control of SKF bearing parts in Yangzhou is the most stringent in the whole machinery industry. The heat treatment of bearing has made great progress in the past 20 years, mainly in the following aspects: the basic theory of heat treatment, the research of heat treatment technology and application technology, the development of new heat treatment equipment and related technology.
