Roll allocation method and device for optimization of roll pass system

Abstract

The invention provides a technical scheme of a roll allocation method and device for optimization of a roll pass system. The scheme comprises three types of rolls with the specifications of phi 610*760, phi 770*1000 and phi 860*1200, a guide mechanism used for guiding steel materials and a cooling mechanism used for cooling the steel materials. The roll allocation method and device for optimization of the roll pass system are characterized in that the three specifications of rolls are semi-steel rolls with the carbon content of 1.6%, each of the three specifications of rolls is additionally provided with a roll groove on the premise that the safety factor of roll rings is 0.6-0.9, and the section area of each roll groove is smaller than or equal to the section area of original roll grooves of the three specifications of rolls. Meanwhile, in order to adapt to the variation of the roll grooves of the rolls, the guide mechanism and the cooling mechanism are modified, the single-groove rolling amount of the rolls is largely improved, and the problems of low work efficiency and heavy workloads on technical personnel caused by frequent replacement of the rolls are avoided.

Description

technical field [0001] The invention relates to a finishing mill, in particular to a roll matching method and a roll matching device for optimizing a roll pass system. Background technique [0002] Rolling mills are commonly used equipment for processing and forming metal products in the metallurgical industry, and rolls are important parts of rolling mills. The hot rolling of the rolling mill is to guide the high-temperature (≥1000°C) metal billet through the auxiliary equipment (guide device) before and after rolling, and continuously pass through different pass types between the rolls, and finally roll the metal billet into metal. The pass design and configuration of the roll is a necessary link in the steel rolling production in the metallurgical industry. [0003] Special steel bars with specifications of φ120-φ320 have a wide range of applications and high added value. As we all know, in the prior art, when a rolling mill is used to roll steel bars in large quantiti...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to aim at the deficiencies existing in the prior art, and to provide a roll matching method and a technical scheme of a roll matching device optimized for the roll pass system. Rolls of different specifications are added with a rolling groove. At the same time, in order to adapt to the change of rolling grooves, the guide mechanism and cooling mechanism are also improved, which greatly increases the rolling capacity of the single groove of the rollers and avoids frequent replacement The problems of low work efficiency and heavy workload of technicians brought about by rolls
