Another method of granulation is that the stream of slag as it issues from the furnace is struck by a jet of highpressure steam or air, which has the effect of blowing the slag into fine threads and globules, much the same as slag wool.

developed this slag granulation method considering that the conventionally treated slag cannot be fully utilised due to the lower cementitious activity caused by water treatment. Process: Homogenising and composition modifying the molten slag; Water quenching and granulation;

Ironmaking and steelmaking Direct reduction, scrap processing, melting, refining and recovery plants

second granulation tank, one granulation unit can handle the slag of two tap holes. `Continuous filtering and evacuation of dewatered slag sand up to its storage facility without interruptions for purging. ` High reliability. `Measurement of slag flow, due to the design of the drum and the dewatering process.

SLAG GRANULATION PROCESS The Classical granulation process has been employed for a long time, and I do not believe it is necessary to describe it at this time. » Free online chat! The SLAG REC project for an innovative direct dry granulation of .

Feb 22, 1983· The average size of granules of slag produced in the abovedescribed method is known to be partly a direct function of the temperature of the water with which the molten slag is mixed. Thus, the average size of the slag particles formed during the granulation process will increase with an increase in the temperature of the granulation water.

new process for dry granulation and recovery of heat from molten slag Essentially, the process is to atomize the molten slag and then to cool the particles rapidly so as to produce a glassy slag. The atomization is done using a rotarycup, airblast atomizer.

(4) A post process for drying slag is a must after the water quenching. (5) The thermal energy of high temperature slag is wasted without recovery. To solve these problems, we studied the dry granulation of the molten slag by rotary cup atomizer (RCA). The molten slag was supplied to the center of RCA.

the process is environment friendly, short process flow and resource reusable. The technology in the world takes the lead in realizing steelmaking slag does not fall to the ground, has been successfully in BaoSteel, Maanshan Iron and steel, Handan Iron and steel,

SLAG IRON AND STEEL 16 Slag Iron and Steel S lag is a byproduct generated during manufacturing of pig iron and steel. It is produced by action of various fluxes upon gangue materials within the iron ore during the process of pig iron making in blast furnace and steel manufacturing in steel melting shop.

Granulation is the process of collecting particles together by creating bonds between them. Bonds are formed by compression or by using a binding agent. If one were to make tablets from granulated sugar versus powdered sugar, for example, powdered sugar would be difficult to compress into a tablet and granulated sugar would be easy to compress.

A typical granulation process, such as described in commonly owned Pat. No. 4,123,247, produces a socalled fluent slag slurry, that is a mixture of slag granules and water. It is necessary to separate the water from the granulated slag so that this granulated slag can be stored, transported and used. ...

Paul Wurth has developed the INBA ® slag granulation process, ... can be done adjacent to the furnace or can be split up to suit available plant space or logistics. Read More Zero Waste .

Jinan Steel has been using this process for BOF slag granulation since 1978 for their 25 ton BOF. To avoid explosion, the flow rate of quenching water and Request Quotation. experimental observation of the slag granulation process. That is, the mechanism of slag granulation was first observed experimentally using a highspeed Request Quotation

The batchwise operating BSSF plants have short process times and a compact design. They achieve a high level of slag and crude steel metal separation, uniform granulation and a consistently high quality in the end products. Further information about solutions for steel works, rolling mills and processing lines can be found at ...
