Problems solved by technology

[0004] In the production process, due to the different expansion coefficients of the metal components in the composite metal strip, the composite is often not tight during the cold rolling process, and small cracks appear. At the same time, the wear resistance, toughness and fatigue resistance of the metal are caused by repeated deformation. reduce

Embodiment 1

[0030] The present invention proposes a metal plate and strip rolling process based on liquid carbon dioxide cooling and lubrication, comprising the following steps:

[0031] S1: put the metal plate and strip blank into the roll mill for rough rolling, and spray cooling lubricant on the blank at the same time;

[0032] S2: Send the rough-rolled metal sheet and strip blank in S1 to the three-roll cold rolling mill for repeated finish rolling, and spray cooling lubricant at the same time; the deformation rate of each pass is 25%-30%, and the feed rate is 20- 35 cm, three-roll cold rolling mill, each stroke angle is 49 degrees, and the rolling process parameters are 15-18 times / minute, and the cooling lubricant is sprayed at the same time. Inspection and repair of strip blanks. The specific process is to firstly use C5 grade ultrasonic for flaw detection. Under the premise of not affecting the length of metal strip blanks, parts of the inner and outer surface defects that are obv...

Abstract

The invention discloses a metal plate strip rolling process based on liquid carbon dioxide cooling and lubrication. The metal plate strip rolling process based on the liquid carbon dioxide cooling andlubrication comprises the following steps: S1, a metal plate strip blank is put into a roller mill for rough rolling, and a cooling lubricant is sprayed on the blank; S2, the metal plate strip blanksubjected to rough rolling in the S1 is fed into a three-roller cold rolling mill for repeated finish rolling, and the cooling lubricant is sprayed at the same time; and S3, the process of the metal plate strip blank preparation, the adjustment of a deformation rolling tool and the preparation process of lubricating coolant need to be carried out again every two passes of rolling, and then the thickness deviation adjustment of the metal plate strip blank in the corresponding passes is carried out until a finished product meeting the requirements is rolled out. According to the metal plate strip rolling process based on the liquid carbon dioxide cooling and lubrication, the sectional cold rolling process is adopted in the rolling process, the strength of the metal plate strip blank can be improved by controlling the cooling speeds of different temperature sections, and the contradiction between the hardness and the strength, the wear resistance, the toughness and the fatigue resistanceof the metal plate strip blank can be better solved.

Description

technical field [0001] The invention relates to the technical field of metal plate and strip rolling, in particular to a metal plate and strip rolling process based on liquid carbon dioxide cooling and lubrication. Background technique [0002] It is a plate and strip produced by metallurgical combination of two or more metals with different materials and properties through composite processing. The metal strip made of only two metals compounded on one side is called bimetal strip (see bimetal strip), and the composite plate with steel plate as the base plate covered with other metal or non-metal plates is called composite steel plate, which is a composite plate strip. main species in. [0003] Composite strips made of dissimilar materials overcome some of the shortcomings of a single component and give play to the respective advantages of different components, thus showing good comprehensive properties, such as high specific strength, good electrical conductivity, and ther...
