Description

technical field

[0001] The invention relates to a debugging method of metallurgical equipment, more specifically, the invention relates to a method for controlling roll zero adjustment of a universal section steel rolling mill. Background technique

[0002] The reversible universal section steel rolling mill adopts the rolling method of four rollers (namely upper horizontal roller, lower horizontal roller, driving side vertical roller and non-driving side vertical roller). In order to obtain the rolling zero position of the four-roller and eliminate the influence of the mechanical gap on the rolling precision, the pressing and pressing of the rolling mill need to be zero-adjusted, that is, to make the four-roller of the rolling mill press against each other and align without rolling workpieces.

[0003] At present, the following problems generally exist in the zero adjustment of the reversible universal section mill with dynamic axial adjustment of the top roll at home and a...
