Hydraulic tension warm-rolling machine

Abstract

The invention discloses a hydraulic tension warm-rolling machine which comprises a four-roller reversible mill, tension devices distributed on the two sides of the four-roller reversible mill, a sample heating device, a hydraulic system and an electric control system. According to the hydraulic tension warm-rolling machine, the tension devices are used for exerting tension on samples, the samples are heated online in a resistance heating mode, through a power adjustment control unit and closed-loop control over the heating temperature, different metal strips which are not prone to deformation at normal temperature can be subjected to strip tension rolling experiments within the temperature range from indoor temperature to 800 DEG C, and technical conditions are created for developing different warm-rolling technologies and industrially producing metal thin strips which are not prone to deformation at normal temperature; the samples are single metal strips, compared with a traditional winding type rolling mill, experiment materials can be saved, and experiment cost is lowered.

Description

technical field [0001] The invention relates to metal strip rolling, in particular to a hydraulic tension warm rolling mill for rolling a single metal strip by on-line heating and applying tension. Background technique [0002] As we all know, for metal materials that are difficult to deform at room temperature, the preparation process is usually complicated. [0003] Taking high-silicon electrical steel among ferrous metals as an example, its plasticity at room temperature is almost zero, and it is difficult to process it into thin sheets required for use. At present, only the CVD method (chemical vapor deposition silicon infiltration method) of JFE Company in the world has realized the industrial scale production of high-silicon electrical steel thin strip. However, this method has the disadvantages of long process flow, heavy environmental burden, low production efficiency and high cost. Improving the plastic deformation ability of high-silicon electrical steel by heati...

Problems solved by technology

The experimental rolling mill solves the problem of applying tension to a single metal strip sample through a tension device, but does not consider the heating of the metal strip, and cannot be directly used for warm rolling of the metal strip
