Factors affecting the supply of steel

Natural gas prices are a function of market supply and demand Because of limited alternatives for natural gas consumption or production in the near term, even small changes in supply or demand over a short period can result in large price movements that bring supply and demand back into balance.

Hot simulation tests at different deformation technology parameters were carried out for a microalloyed high strength steel produced by CSP hot rolling and the stress-strain curves during deformation were measured.

Based on the experimental results and the discussions of present flow stress models, a new flow stress model incorporating interactional effect of deformation temperature, strain and strain rate on flow stress was developed in the paper.

Excellent agreement between measured and predicted flow stress values is obtained for new flow stress model of a microalloyed high strength steel rolled by CSP. In addition, the comparisons of flow stress prediction errors between several models and one given in the paper reveal that the prediction accuracy of new flow stress model presented in the paper is higher than other models.

CSP rolling mill abnormal vibration problem is one of the worldwide difficult problems in rolling fields. In this article, using the modern acceleration telemetry system, an integrated test is taken to the rolling mill vibration and the laws of the mill vibration are captured.

The test shows that there is severe horizontal vibration of roll system, especially the work rolls, at the same time, there are also abnormal vibration occurs on AGC automatic gauge control.

In order to reveal the internal links between the vertical vibration of AGC and horizontal vibration of the roll system, using the harmonic analysis module and the transient response analysis module of ANSYS software, through simulation study to research the impact of the vertical vibration of AGC on the horizontal vibration of the roll system and meaningful conclusions are clarified.

The distribution and change of temperature, stress and strain field in rolling process were analyzed.

In the view of boundary conditional influence on temperature, some factors such as thermal exchange between the work-roll and the thin slab, plastic deforming quantity of heat, cooling flux, convection and radiation heat exchange were considered during simulation. The results show contact heat conduction and deformation heat are the main factors that influence the temperature change of the thin slab.

A good agreement was found between the predicted and the experimental data. With cold rolling base plate of low carbon steel by CSP process, the cold deformation experiments were carried out by the two-roller reverse-mill in the laboratory. The work-hardening was studied for different deformation plates through the room temperature tensile and microhardness measured, and the microstructure was also studied after deformation.

It was found that the steel yield and tensile strength increased and work-hardening marked with the deformation augment, the test steel microstructure is ferrite with mingle small amount pearlite, its grain is refined and elongated with deformation increasing.
