Abstract:
In past years, the exploitation of mineral resource in our country was stressed on capacity and the solid waste recycle and innocent treatment was ignored. Much valuable metal is associated and coexist with waste, it is in difficult position for present technology to recycle valuable composition in that waste, which leads to valuable component loss and environment pollution. Therefore, the development and utilization of copper refining slag is in significance. In this paper, the advantages and difficulties to process refining slag by flotation method are discussed based on property analysis of

Abstract:
On the basis of the formulated mathematical model for the study of electromagnetic processes in a two-phase (two-inductor) induction channel furnace, electrical losses in the metal frameworks of the furnace were calculated for vari-ous options for their sectioning. The influence of the phase angle between the voltages feeding the inductors of the fur-nace on the distribution of specific and integral losses in the frames is determined. Practical recommendations for re-ducing these losses in order to increase the efficiency of melting furnaces are presented. Ref. 5, fig. 5.

The article is devoted to the analysis of the influence of tunneling channel height change on its aerodynamic characteristics by modeling the velocity and pressure distribution of air and furnace gases. Three variants of the tunnel geometry were considered: basic, with reduced height in the firing zone and with reduced height along the entire length of the furnace. The simulation results in the dependence of the static pressure along the length of the furnace and the velocity of the furnace gas moving along its height.

Abstract:
In modern blast furnace production, even a short-term disruption of the technological process is associated with large productivity losses. In the practice of conducting blast furnace melting, there are often significant deviations from the optimal mode. They can lead not only to disruptions of the blast furnace, but also to accidents. In the operation of a blast furnace, typical deviations from the normal distribution of gas flow and charge materials include: peripheral, axial, channel passages; skewing of the backfill level; varying degrees and types of charge suspension. As a result, there

Abstract:
Sinter sensible heat recovery via a vertical cooling furnace is a new type of waste heat recovery process proposed based on coke dry quenching. However, the segregation of the burden in a vertical cooling furnace is serious, resulting in a large amount of cooling gas escaping from the short-circuit channel of the vertical cooling furnace, which seriously affects the uniform gas–solid heat transfer in the furnace. To improve the burden distribution and gas flow in such a furnace, this paper proposes a Venturi-type vertical cooling furnace. Based on the single silo of a vertical cooling furnace

Based on the theory of thermal circuits, a computer model of an induction channel furnace has been developed, which is used to obtain industrial copper wire rods in the mode of continuous casting.

In the developed thermal model, it is proposed to consider the convection fluxes of heat in the metal using controlled current sources.

A three-dimensional mathematical model is developed to describe the influence of AGD beams on gas distribution in COREX-3000 shaft furnace.

AGD channels can lead reduction gas into shaft center, and increase the gas velocity at slots level, but it have little effect on gas distribution at upper part of the furnace. AGD beams are also good at restraining down pipe gas, and the volume fraction of down pipe gas declines from 9
