By studying the laws and influencing factors of heat generation, consumption, transfer and accumulation in the sinter bed, the relations among energy phase, temperature range, change gradient, microscopic atmosphere and sintering mineralization (production and quality) are revealed, a mathematical model of sinter bed with uniform heat and a mathematical algorithm for solving layered heat supplementation are established, a method to achieve low-carbon hydrogen-rich sintering with uniform heat based on benchmark carbon distribution plus layered heat supplementation is developed, and a small-scale test experiment based on the raw material conditions of Zhongtian Iron and Steel is carried out. The results show that after applying the layered heating sintering method, such indicators as sintering speed, sintering yield, tumbler strength, and utilization coefficient increase slightly compared with the benchmark working conditions, and the total carbon formulation decreases from 4.00% to 3.25%.
