Slag/refractory and metal/refractory interactions during the production of stainless steels N. SUTCLIFFE Columbus Stainless, South Africa Refractories and slags play a vital role in the production of stainless steel. They are in intimate contact with the steel at temperature, and chemical reactions between the three can and do occur.

Finishing stainless steel assemblies for handling food and beverage applications is more complicated than non-sanitary applications. Knowledge of the tools, consumables, and techniques is critical, but likewise the contractor must be familiar with sanitary standards so the system and its finish are optimal the demands for this type of application.

FIELD: metallurgy. SUBSTANCE: invention relates to metallurgy and can be used for production of stainless martensitic steel. Before the stage of electroslag remelting the ingot is subjected to degassing in vacuum in liquid metal condition within the time period sufficient to get the content of hydrogen in the named ingot after the named stage of electroslag remelting less than 3 ppm.

The selection of the right stainless mold steel grade greatly depends on the application. Understanding all of the factors in advance can determine the success of a project. Look for a material supplier with years of experience in tool steel production, heat treatment, laboratory services as well as sales and technical support.

The final products of steel slag crushing production line are mainly slag steel and magnetic separation powder. The former can be reused in steelmaking and the latter can be reused in sintering. The tailings can also be further processed, such as producing steel slag powder.

1. Introduction. Stainless steel production is currently one of the most dynamic sectors of the manufacturing industry due to a large increase of the use of this product in the construction and industrial sectors; considerable amounts of waste are generated from these factories, .These high amount of waste generated is not only a quantity crisis but also an environmental problem,,, .

The production and use of steel slag then was 16.8 million ... any problem on the production line in time and ensure product ... Stabilizer for Stainless Steel Slag, Kawasaki Steel …

The worldwide production of stainless steel slag is rapidly increased, accounted to nearly 38.1 metric tons in 2013 . During stainless steelmaking process, a vast majority of solid wastes, especially slags is generated from the plants. Approximately, each three metric tons of stainless steel products release one tone of stainless steel slag.
