A rolling process shared by circle 5.5 and thread 6.0

Abstract

The invention belongs to the technical field of metal wire rod rolling, and specifically relates to a rolling process shared by a circle 5.5 and a thread 6.0. There are 28 rolling mills in total, which are rough rolling unit, intermediate rolling unit, pre-finishing rolling unit and finishing rolling unit. Among them, the 1#-6# rolling mill is the rough rolling group, the 7#-12# rolling mill is the middle rolling group, the 13#-14# rolling mill is the pre-finishing rolling group one, and the 15#-18# rolling mill is the pre-finishing rolling group Unit 2, No. 19#-28# rolling mills are finish rolling units, of which the rough rolling unit, intermediate rolling unit and pre-finishing rolling unit 1 are horizontal and vertical alternately, and the pre-finishing rolling The rolling unit is Hafei imitating Morgan 45°, which can realize the common pass of round 5.5 and thread 6.0, which reduces the number of spare roll changes by half, reduces the cost, shortens the time for roll change and slot change, and greatly improves work efficiency. Through production practice, the production is stable and the equipment is normal, with a daily output of more than 1,400 tons.

Description

technical field [0001] The invention belongs to the technical field of metal wire rod rolling, and specifically relates to a rolling process shared by a circle 5.5 and a thread 6.0. Background technique [0002] When rolling metal wire rods, a complete set of matching rolling equipment is required, which is divided into rough rolling group, intermediate rolling group, pre-finishing rolling group, and finishing rolling group. There are more general equipment, and there are more than 20 sets of supporting equipment. Because the pass design of the original round 5.5 and thread 6.0 is not the same, a lot of time is wasted in changing rolls and slots, the work intensity of personnel is high, and the number of spare rolls is increased. In this way, when changing the product model (rolling round 5.5, thread 6.0), due to Different pass types cannot be interchanged, so the whole set of rolls and slots needs to be changed, which leads to a long delay in changing rolls and slots, incre...

[0002] When rolling metal wire rods, a complete set of matching rolling equipment is required, which is divided into rough rolling group, intermediate rolling group, pre-finishing rolling group, and finishing rolling group. There are more general equipment, and there are more than 20 sets of supporting equipment. Because the pass design of the original circle 5.5 and thread 6.0 is not the same, a lot of time is wasted in changing rolls and slots, the work intensity of personnel is high, and the number of spare rolls is increased, so when changing the product model (rolling circle 5.5, thread 6.0), due to Different pass types cannot be interchanged, so a whole set of rolls and slots needs to be changed, which will lead to a long delay in changing rolls and slots, increase the amount of spare rolls, and occupy production costs
