Abstract
The excellent curved method of steel finished product is reduced the invention discloses a kind of, includes the following steps: 1, cp2 operative employee is required to control tapping interval, increase 20-40s or so on the basis of original normal rolling rhythm；I.e. 21 pinion steel of Φ specification rolling rhythm below increases 20s, and 30 pinion steel rolling rhythm of Φ 21- Φ increases 30s, and the above rolling rhythm of 30 pinion steel of Φ increases 40s；2, burner man is required to must assure that steel billet in the time of soaking zone is more than 35min in tapping, to guarantee the time inside furnace of steel billet；3, it is enclosed around cold bed and all at cold bed bottom ventilation and sets heat preservation iron sheet, insulation cover is added above cold bed.
Description
Technical field
The excellent curved method of steel finished product is reduced the present invention relates to a kind of.
Background technique
Small unit often will appear the phenomenon that finished product bending when rolling excellent steel especially pinion steel, cause multiple length can not
Cutting to length is carried out by groove profile cutting edge.It will appear curvature in three sections of chain chain upper fixed rulers after cutting to length to want more than user
The phenomenon that asking.
Summary of the invention
The excellent curved method of steel finished product is reduced the purpose of the present invention is to provide a kind of, the bending of finished product multiple length can be controlled
Degree reduces the finishing time to be cut, and improves operating rate, improves excellent steel lumber recovery, reduces production cost.
The object of the present invention is achieved like this, a kind of to reduce the excellent curved method of steel finished product, includes the following steps: 1, wants
It asks cp2 operative employee to control tapping interval, increases 20-40s or so on the basis of original normal rolling rhythm；That is 21 pinion steel of Φ
Specification rolling rhythm below increases 20s, and 30 pinion steel rolling rhythm of Φ 21- Φ increases 30s, more than 30 pinion steel of Φ rolls section
It plays and increases 40s；2, burner man is required to must assure that steel billet in the time of soaking zone is more than 35min in tapping, to guarantee steel billet
Time inside furnace；3, it is enclosed around cold bed and all at cold bed bottom ventilation and sets heat preservation iron sheet, insulation cover is added above cold bed.
The method of the present invention is simple and easy, can efficiently control finished product multiple length curvature, reduces the finishing time to be cut, and improves
Operating rate improves excellent steel lumber recovery, reduces production cost.
Specific embodiment
It is a kind of to reduce the excellent curved method of steel finished product, include the following steps: 1, cp2 operative employee is required to control tapping interval,
Increase 20-40s or so on the basis of original normal rolling rhythm；That is 21 pinion steel of Φ specification rolling rhythm below increases
30 pinion steel rolling rhythm of 20s, Φ 21- Φ increases 30s, and the above rolling rhythm of 30 pinion steel of Φ increases 40s；2, burner man is required
Tapping when must assure that steel billet soaking zone time be 50min, to guarantee the time inside furnace of steel billet；3, around cold bed and
It is all enclosed at cold bed bottom ventilation and sets heat preservation iron sheet, insulation cover is added above cold bed.
Claims (1)
1. a kind of reduce the excellent curved method of steel finished product, it is characterised in that include the following steps: 1, cp2 operative employee is required to control out
Steel rhythm increases 20-40s or so on the basis of original normal rolling rhythm；That is 21 pinion steel of Φ specification rolling section below
It plays and increases 20s, 30 pinion steel rolling rhythm of Φ 21- Φ increases 30s, and the above rolling rhythm of 30 pinion steel of Φ increases 40s；2, it requires
Burner man must assure that steel billet in the time of soaking zone is more than 35min in tapping, to guarantee the time inside furnace of steel billet；3, cold
It is all enclosed at around bed and cold bed bottom ventilation and sets heat preservation iron sheet, insulation cover is added above cold bed.
