工件的热处理保温温度是影响工件组织和性能的重要工艺参数之一,而热处理炉有效加热区的保温精度直接关系到工件热处理时的保温温度。因此,我国专门制定了一项国家标准GB /T 9452,对热处理炉有效加热区测定方法作出规定,以保证热处理炉保温精度满足工件的热处理要求。GB /T 945
Heat treatment of the workpiece Insulation temperature is one of the important process parameters that affect the structure and properties of the workpiece. However, the heat preservation accuracy of the effective heating area of the heat treatment furnace is directly related to the holding temperature during the heat treatment of the workpiece. Therefore, our country has formulated a national standard GB / T 9452, the heat treatment furnace effective heating zone determination method to make provisions to ensure that the heat treatment furnace insulation accuracy to meet the requirements of the workpiece heat treatment.
