At present, the heating level of most coke ovens is a fixed parameter, coke quality can only be changed by adjusting standard flame path temperature and other production parameters such as coking time in the actual production process, and the high-directional maturation uniformity of coal cakes cannot be fundamentally solved. A7.63 m top-loading coke oven designed and developed by German wood company is provided with adjustable crossing holes, the crossing holes are divided into an upper layer and a lower layer, a round millstone brick is arranged on a vertical fire path between the upper layer crossing hole and the lower layer crossing hole, and the heating level and the furnace top space temperature are adjusted by adjusting the opening and closing of the millstone brick. However, the grinding disc bricks are too large, so that the adjustment is difficult, and the accurate adjustment cannot be performed; therefore, the millstone brick is not regulated basically in the actual production of the coke oven, and the effect of crossing holes on the upper layer and the lower layer is lost. In addition, when the vertical flame path is completely blocked through the millstone brick, the viewing hole is also shielded in practice, so that manual temperature measurement of the vertical flame path cannot be performed.
