Embodiment 1

[0043] Such as figure 1 Shown, a kind of debugging method of BD mill pressing down system, described debugging method comprises the following steps:

[0044] 1) Preliminary determination of the pressure range:

[0045] The pressure calculation of the balance cylinder:

[0046] When using hydraulic balance, the working pressure of the oil cylinder can be determined according to the following formula:

[0047] P 1 = K · G n · πd 2 ( k g / cm 2 ) ;

[0048] In the formula: G—the weight of the balanced part (kg);

[0049] n—the number of hydraulic cylinders is 2;

[0050] d—The diameter of the hydraulic cylinder plunger is 180 (mm).

[0051] Among them, G=2G 1 +2G 2...

Abstract

The invention discloses an adjusting method for a BD rolling mill pressing system. The method includes the following steps that 1, the pressure range is preliminarily determined; 2, pressure is set; 3, balance cylinder system pressure and connecting shaft bracket oil cylinder pressure are adjusted and screened; 4, the balance cylinder system pressure and the connecting shaft bracket oil cylinder pressure are verified; 5, parameters are cured. The adjusting precision of the BD rolling mill pressing system and the stability of equipment can be improved, and smooth production is guaranteed; loads of parts in the BD rolling mill pressing system can be reduced, the service life of spare parts is prolonged, and production cost is reduced. Adjustment of the BD rolling mill pressing system is standardized and modularized, and the technical difficulty of construction is lowered.

Description

technical field [0001] The invention belongs to the technical field of steel rolling, in particular, the invention relates to a debugging method of a pressing system of a BD rolling mill. Background technique [0002] The BD rolling mill is the blanking machine in the big bar rolling line, and its pressing system equipment includes pressing reducer, pressing screw, copper nut, pressing motor, balance cylinder and other components. These components are interrelated and interact with each other. Only by setting reasonable parameters can the stable operation of the entire pressing system be guaranteed, otherwise it will lead to a reduction in the service life of spare parts, an increase in energy consumption, and a decline in product quality. In the past, parameter setting provided parameter setting values ​​by drawings or schematic diagrams, usually theoretical setting values, not actual optimal parameters. The key parameters that need to be determined are balance cylinder pr...
