Nodular cast iron pipe curing method and device
The invention provides a nodular cast iron pipe curing method and device, and belongs to the technical field of nodular cast iron pipes. The nodular cast iron pipe curing method comprises the following steps that S100, natural curing is performed: a nodular cast iron pipe is left to stand for first preset duration under the conditions of a first preset temperature and a first preset relative humidity; S200, steam curing is conducted, specifically, S210, a curing kiln is continuously filled with steam, a temperature in the curing kiln is continuously increased according to a first temperature increasing rate till the temperature is increased to a second preset temperature, and the first temperature increasing rate is not larger than 15 DEG C/h; and S220, heat preservation is conducted for second preset duration under the second preset temperature condition till curing is completed. According to the nodular cast iron pipe curing method, cement on a lining layer of the nodular cast iron pipe is cured through natural curing and steam curing so as to bear a subsequent heating process, the temperature increasing rate is not more than 15 DEG C/h, so that the defects of cement peeling, bulging and the like are prevented, and the quality of the nodular cast iron pipe lining layer is improved.
本发明提供了一种球墨铸铁管养生方法及装置，属于球墨铸铁管技术领域，球墨铸铁管养生方法包括以下步骤：S100、自然养生：使球墨铸铁管在第一预设温度和第一预设相对湿度条件下静置第一预设时长；S200、蒸汽养生：S210、向养生窑中持续充入蒸汽，并使所述养生窑内按照第一升温速率持续升温，直至升温至第二预设温度，所述第一升温速率不大于15℃/h；S220、在所述第二预设温度条件下保温第二预设时长，直至养生完成。本发明球墨铸铁管养生方法分别通过自然养生与蒸汽养生对球墨铸铁管内衬层上的水泥进行养生，以承受后序的升温过程；升温的速率不大于15℃/h，从而防止水泥起皮、鼓包等缺陷的产生，提高了球墨铸铁管内衬层的质量。
