RM_3-75-9D滴控箱式多用炉(见图1)是可控气氛热处理的一种较先进的设备。它采用有机化合物直接滴入炉内裂解制取可控气氛。具有结构简单,成本低,碳势可控的特点。供各种齿轮,中小型合金钢模具热处理以及自行车、缝纫机等轻纺机械小零件的薄层渗碳、碳氮共渗。并能做到渗层均匀、淬火后变形小,无氧化脱碳,表面光亮。本文以南京电炉厂生产的RM_3-75滴控多用炉为例介绍滴控箱式多用炉(以下简称为滴控炉)的性能及其热处理工艺。
RM_3-75-9D drip box multi-purpose furnace (see Figure 1) is a more advanced controllable atmosphere heat treatment equipment. It uses organic compounds directly into the furnace cracking prepared controlled atmosphere. Has a simple structure, low cost, carbon potential controllable features. For a variety of gears, small and medium alloy steel mold heat treatment and bicycles, sewing machines and other textile machinery small parts of the thin-layer carburizing, carbonitriding. And to achieve uniform infiltration layer, small deformation after quenching, no decarbonization, surface bright. In this paper, Nanjing Electric Furnace factory production RM_3-75 drip multi-purpose furnace as an example to introduce the drip-box multi-purpose furnace (hereinafter referred to as drip furnace) performance and heat treatment process.
