消除球罐残余应力的热处理方法很多,较常见的如罐内燃烧的“Hauck”喷嘴法,燃烧丙烷气的喷嘴法,罐外燃烧的烟气法,还有红外线板式加热器的局部热处理方法等等。如何根据具体情况,选择相适应的热处理方法,是提高经济效益,达到预期目的的关键。下面介绍一下我们的实际做法。一、热处理的方案选择我们公司是一个综合性的安装企业,设有热处理的专业人才,更没有热处理的实践经验。我们省也没有罐内燃烧法热处理需要的液化石油气,而且工程上除了要热处理两台球罐外,还有一台φ3M×34.5M 的高塔也要进行热处理。热处理现场又处于化工厂禁火区之内。因此我们选择了操作简便,升降温平稳,安全可靠,不需要可燃气体,球罐和高塔可以兼用,
There are many heat treatment methods to eliminate the residual stress of the spherical tank. The more common ones are the “Hauck” nozzle method for combusting the tank, the nozzle method for burning propane gas, the flue gas method for burning outside the tank, the local heat treatment method for the infrared plate heater, and the like Wait. How to choose the appropriate heat treatment method according to the specific situation is the key to improve the economic efficiency and achieve the expected goal. Here’s what we do. First, the choice of heat treatment options Our company is a comprehensive installation of enterprises, with heat treatment professionals, but no heat treatment of practical experience. In our province, there is no liquefied petroleum gas required for the heat treatment of the tank combustion method, and in addition to heat treatment of two spherical tanks, there is also a φ3M × 34.5M tower also heat treatment. Heat treatment site is in the fire area of chemical plants within. Therefore, we have chosen a simple, smooth heating and cooling, safe and reliable, does not require combustible gas, cans and towers can be combined,
