Fireproof cable production process

The invention relates to a fireproof cable production process, which comprises the following steps: S1, material pretreatment: carrying out pretreatment on a copper core, a filling layer and a copper strip; s2, reducing, wherein the filling layer and the copper strip are pressed and fixed in the circumferential direction of the copper core through reducing equipment; s3, a protection layer is poured, the diameter-reduced cable penetrates into an injection molding machine, and pouring of the protection layer is carried out in the injection molding machine; s4, flaw detection: flaw detection is carried out on the cable after the protection layer is poured by using detection equipment; and S5, outer diameter detection: detecting the outer diameter of the cable subjected to flaw detection by adopting detection equipment. The cable production process has the effect of improving the production efficiency of the cable production process. 本申请涉及一种防火电缆生产工艺，包括如下步骤：S1：材料前处理，将铜芯、填充层和铜带进行前处理；S2：缩径，通过缩径设备将填充层和铜带压设固定在铜芯周向；S3
