Then planning weights of raw materials can't be calculated accurately so as to influence raw material cost planning control.
They don’t analyze and predict alloy element yield in the view of the whole smelting process and change of raw materials.
(2) Raw material factors The raw materials include scrap steel, cast iron, return steel, alloys, accessory material, deoxidizer and addition alloy in refining process.
With the constraint conditions of raw materials, processes, etc. of smelting stage, the prediction model of alloy element yield is built.

Apart from the accumulators, nowadays it is widely used in the production of glass and ceramics (30%), lubricating materials (11 %), metallurgy (4%), as well as in the production of chemicals, pharmaceuticals, rubber, and others [1].
The steadily growing interest in lithium products contributes to research and search for technological solutions involving the lithium-containing hydromineral raw materials in the processing sector, one of which is associated formation brines formed during the development of oil and gas fields.
Such materials have high adsorption capacity; in alkali media (рН ~8) lithium had concentration 400 times higher.

As with screw conveyor, the vanes of spiral rotate with the shaft together also, but materials are rotating and transported in the trough formed by material and keep dropping at the same time.
This is the root cause of segregation of the material when the paver works.

A Process is a series of operations which produce a physical or chemical change or biotransformation in the nature of a material.
The process industries are facing to processes, and their materials are fluids or mixture of fluids and solids.
Researchers from Institute of Process Engineering, Chinese Academy of Sciences, compiled and published a book named as “Process Engineering------ materials·energy resources·wisdom” with 717 pages in the year of 2010, which includes the most developments of process engineering in China [4].
