Jointly Develop and Test of Electrical-Hydraulic Stepping Cylinder

Abstract

The working principle of the Electrical-hydraulic Stepping Cylinder for widening is introduced in detail. Established the mathematical model. The test method for the stepping cylinder is designed in combination with the actual use conditions. The use of an on-line continuous casting machine has verified that this test method can fully satisfy the widening stepping cylinder factory test requirements. It sets a precedent for nationalization of stepping cylinder.
