Description
技术领域 technical field
本发明属于镀锌带钢保温技术领域，尤其涉及一种阻碍镀锌带钢保温段热气流上升的装置及其使用方法。 The invention belongs to the technical field of heat preservation of galvanized steel strips, and in particular relates to a device for hindering the rise of hot air in a heat preservation section of galvanized steel strips and a method for using the same.
背景技术 Background technique
带钢镀锌后，被感应加热段的感应加热器快速加热到所要求的合金化温度，然后进入合金化炉的保温段。根据合金化加热工艺曲线的要求，镀锌带钢需在一定的温度范围内维持一段时间，以完成合金化过程。为补偿散热损失，在镀锌带钢保温段的底部布置有可控硅连续控制的电阻辐射管加热器；在镀锌带钢保温段的入口处也安装密封挡板，以减少冷空气进入保温段；在镀锌保温段的出口处设置了翻板式密封设备，以限制保温段的热气流进入冷却段。 After the steel strip is galvanized, it is quickly heated to the required alloying temperature by the induction heater in the induction heating section, and then enters the heat preservation section of the alloying furnace. According to the requirements of the alloying heating process curve, the galvanized steel strip needs to be maintained in a certain temperature range for a period of time to complete the alloying process. In order to compensate for the loss of heat dissipation, a resistance radiant tube heater continuously controlled by a thyristor is arranged at the bottom of the galvanized strip insulation section; a sealing baffle is also installed at the entrance of the galvanized strip insulation section to reduce cold air from entering the insulation section; at the outlet of the galvanized heat preservation section, a flap-type sealing device is installed to limit the hot air flow of the heat preservation section from entering the cooling section.
实际运行效果表明，镀锌保温段出口处设置的翻板式密封设备，不能有效地限制因烟囱效应而抽吸的空气量，也不能使炉压保持稳定。 The actual operation results show that the flap-type sealing equipment installed at the outlet of the galvanized insulation section cannot effectively limit the amount of air sucked by the chimney effect, nor can it keep the furnace pressure stable.
