Method for controlling negative deviation of steel bar with rib

Abstract

Provided is a control method of rib steel minus deviation for controlling rib steel minus deviation in the producing process. The control method is characterized in that the control method includes that in the rib steel producing process, a weight W blank can be gained after continuous weighing for the blank weight, a sample of the end product work section are figure up for the sample with weight W1, according to the deviation Wdev which is between the W blank and the sample weight W1, the rib steel assembly line can be adjusted and the end rib steel product with rational minus deviation can be produced. The control method of rib steel minus deviation employs the steel density invariance principle and weight method, the timely production adjustment can be realized by the appraise deviation and the D-value of the weight of end rib steel product and the theoretical minimum weight, the maximum minus deviation production of the rib steel can be high limit realized accurately, the control accuracy of the minus deviation can be highly improved, the mistake of the minus deviation control can be reduced, the maximum economic benefit can be realized in the rib steel manufacturing enterprises.

Description

technical field [0001] The invention belongs to the technical field of steel bar wire production in iron and steel smelting, and in particular relates to a method for controlling negative deviation of ribbed steel bar for reasonable negative deviation control in the rolling production process of ribbed steel bar. Background technique [0002] Steel rolling enterprises in the metallurgical industry can increase the yield without increasing or reducing investment through reasonable negative deviation rolling when rolling steel products. Negative deviation control is an effective way for iron and steel enterprises to improve economic benefits. At present, the competition in the steel market is becoming increasingly fierce, and users' requirements for product quality are also increasing, which undoubtedly increases the difficulty of improving the yield. Negative deviation rolling is to control the cross-sectional size of the finished steel within the negative deviation range of ...
