Dry quenching oven heating method and starting method

The invention discloses a dry quenching oven heating method and a starting method, and belongs to the technical field of coking. The heating method of the oven comprises the following steps: S1, determining an expansion curve of a key refractory brick sample: testing an accumulated thermal expansion coefficient and an average thermal expansion coefficient; s2, the daily expansion rate is determined, and the heating rate is controlled according to the daily expansion rate; and S3, formulating a baking oven temperature rise chart and curve, and calculating the baking oven interval day number and the daily rising temperature. Wherein the key refractory brick body is a mullite-silicon carbide brick adopted by a chute bracket and a mullite brick adopted by an annular air passage of a pre-storage chamber. According to the thermal expansion performance of the key refractory, the oven heating method with a scientific basis is theoretically researched, reasonable expansion of the refractory in the oven drying period o
