Description

一种烧结炉脱蜡结构及烧结炉A sintering furnace dewaxing structure and sintering furnace

技术领域technical field

本发明涉及冶金设备技术领域,尤其涉及一种烧结炉脱蜡结构及烧结炉。The invention relates to the technical field of metallurgical equipment, in particular to a dewaxing structure of a sintering furnace and a sintering furnace.

背景技术Background technique

烧结炉是一种可以给物料提供特定温度和特定环境压力以及真空度的热处理炉具,烧结炉一般包括:真空装置、加热保温装置、工艺气体装置、冷却装置(循环水冷和压力快冷等)、控制装置以及脱蜡装置,其中脱蜡装置的作用是收集产品中加入的成型剂。为了使产品更好的成型,通常需要在产品种加入成型剂,但是成型剂如果停留在产品中会影响产品的质量。成型剂在高温情况下会处于一种气化状态,通过真空泵组抽取气化的成型剂进行定向的运动,并通过脱蜡装置,将成型剂液化,从而完成成型剂的收集和存储。现有的脱蜡装置如图1所示,烧结炉脱蜡时,真空泵组抽取从抽口121抽取脱蜡装置中的气体,使得气体成型剂进入脱蜡装置,一级脱蜡装置11的夹套14中通入冷流体,气态成型剂通过进气口111进入一级脱蜡装置11,气态成型剂会液化储存在一级脱蜡装置11中,剩余没液化的气态成型剂通过连接通道13后被二级脱蜡装置12再次液态化流入一级脱蜡装置11中。脱蜡装置排蜡时,一级脱蜡装置11的夹套14中通入热流体,让成型剂无法固态化,保持在液态化从出蜡口112排出。然而,现有的脱蜡装置在烧结炉脱蜡工作中,脱蜡装置中的液态成型剂都会流向堆积在一级脱蜡装置的最低处,一级脱蜡装置夹套中通入的流体单一,对成型剂状的态控制能力差。流体过冷时:堆积在一级脱蜡装置的液态成型剂会固态化,导致烧结炉内气态成型剂抽出不顺畅有残留,严重影响产品质量。流体过热时:气态成型剂进入一级脱蜡装置液化效率不高,气态成型剂被抽入真空泵组中,影响真空泵组使用寿命。Sintering furnace is a heat treatment furnace that can provide specific temperature, specific environmental pressure and vacuum degree to materials. Sintering furnace generally includes: vacuum device, heating and heat preservation device, process gas device, cooling device (circulating water cooling and pressure fast cooling, etc.) , a control device and a dewaxing device, wherein the function of the dewaxing device is to collect the molding agent added to the product. In order to make the product better, it is usually necessary to add a molding agent to the product, but if the molding agent stays in the product, it will affect the quality of the product. The molding agent will be in a vaporized state at high temperature. The vaporized molding agent is extracted by the vacuum pump group for directional movement, and the molding agent is liquefied by the dewaxing device, so as to complete the collection and storage of the molding agent. The existing dewaxing device is shown in Figure 1. When the sintering furnace is dewaxing, the vacuum pump group extracts the gas in the dewaxing device from the suction port 121, so that the gas forming agent enters the dewaxing device. A cold fluid is introduced into the jacket 14, the gaseous forming agent enters the primary dewaxing device 11 through the air inlet 111, the gaseous forming agent is liquefied and stored in the primary dewaxing device 11, and the remaining unliquefied gaseous forming agent passes through the connecting channel 13. Afterwards, it is liquefied again by the secondary dewaxing device 12 and flows into the primary dewaxing device 11 . When the dewaxing device discharges wax, a hot fluid is introduced into the jacket 14 of the primary dewaxing device 11 , so that the molding agent cannot be solidified, and is kept in a liquid state and discharged from the wax outlet 112 . However, in the dewaxing work of the sintering furnace in the existing dewaxing device, the liquid forming agent in the dewaxing device will flow to the lowest part of the first-stage dewaxing device, and the fluid introduced into the jacket of the first-stage dewaxing device is single. , the state control ability of the molding agent state is poor. When the fluid is supercooled: the liquid forming agent accumulated in the first-stage dewaxing device will be solidified, resulting in the unsmooth extraction of the gaseous forming agent in the sintering furnace and residues, which seriously affects the product quality. When the fluid is overheated: the liquefaction efficiency of the gaseous forming agent entering the first-stage dewaxing device is not high, and the gaseous forming agent is pumped into the vacuum pump group, which affects the service life of the vacuum pump group.
