Rolled steel production quality root cause determination method, device and equipment and storage medium

The invention provides a steel rolling production quality root cause determination method, device and equipment and a storage medium, and the method comprises the steps: collecting historical production data, carrying out the clustering processing of the historical production data to construct a state space, and obtaining a current quality result based on a steel rolling quality state in the state space; counting the causal relationship between each initial intervention amount and the current quality result to obtain an intervention causal factor, determining the initial intervention amount with the intervention causal factor greater than or equal to a preset causal threshold as a key intervention amount, and calculating the correlation between each key intervention amount and the current quality result to obtain a related causal factor; and finally, determining the key intervention amount of which the difference value between the intervention causal factor and the related causal factor is greater than a pres
