Technology for Electroslag Remelting with Rotation of the Consumable Electrode
is known that metal which is produced by the method of electroslag remelting (ESR) has service properties superior to those of metal made by open refining and casting. This can be attributed to the better conditions which exist for refining in the specially chosen slag and for the crystallization of the metal in the case of ESR. However, the need for a two-stage metallurgical conversion (essent...
متن کاملMultivariable PID Decoupling Control Method of Electroslag Remelting Process Based on Improved Particle Swarm Optimization (PSO) Algorithm
A mathematical model of electroslag remelting (ESR) process is established based on its technical features and dynamic characteristics. A new multivariable self-tuning proportional-integral-derivative (PID) controller tuned optimally by an improved particle swarm optimization (IPSO) algorithm is proposed to control the two-input/two-output (TITO) ESR process. An adaptive chaotic migration mutat...
متن کاملEffect of Current on Structure and Macrosegregation in Dual Alloy Ingot Processed by Electroslag Remelting
Macrosegregation is a very common problem for the quality control of all cast ingots. The effect of current on the structure and macrosegregation in dual alloy ingot processed by electroslag remelting (ESR) was investigated experimentally with various analytical methods. In this study, the electrode consisted of NiCrMoV alloy bar (upper part) and CrMoV alloy (lower part) with a diameter of 55 m...
متن کاملThe Structural Evolution and Segregation in a Dual Alloy Ingot Processed by Electroslag Remelting
The structural evolution and segregation in a dual alloy made by electroslag remelting (ESR) was investigated by various analytical techniques. The results show that the macrostructure of the ingot consists of two crystallization structures: one is a quite narrow, fine, equiaxed grain region at the edge and the other is a columnar grain region, which plays a leading role. The typical columnar s...
متن کاملAn Experimental Study of the Effects of the Mud Boil-up Process on the Physico-Chemical Properties of Grape Syrup
The deficiency of calcium, magnesium, potassium, and iron leads to severe disorders in human body organs. This study introduces Dooshab as a food source of these useful elements. The Dooshab which translates to grape syrup is widely used in Iran. In the traditional method of the Dooshab production, the white soil is added to the grape juice and the mixture is boiled. After cooling, it is fi...
