Development of refractories and related products for

The transformation of the consumption of refractories for the production, out-of-furnace treatment, and casting of steel is considered. The main trends in developing the refractory market are shown to be a significant decrease in the specific consumption of refractories per 1 t liquid steel and the predominant application of refractories based on magnesia raw materials and fused corundum for

Steel Cleanliness

2011/1/7The total oxygen levels in ball-bearing steels produced at Ovako Steel Hofors (former QIBR steel) via the acid open hearth process (1964) and later via an electric arc furnace and an ASEA-QIBR ladle furnace followed by ingot casting are given in Figure 1.7.11.

Ladle refining [SubsTech]

2012/5/31In addition to deoxidation vacuum treatment helps to remove Hydrogen dissolved in liquid steel. Hydrogen diffuses into the CO bubbles and the gas is then evacuated by the vacuum pump. Movement of the molten steel caused by CO bubbles also results in refining the steel from non-metallic inclusions, which agglomerate, float up and are absorbed by the slag.

A Study on Molten Steel/Slag/Refractory Reactions during Ladle Steel

3 ABSTRACT During the production of steel the degree of oxide inclusions partly depends on the reaction of the melt with the furnace lining, the ladle lining and the pouring system. The refractory material may be eroded by the molten steel and slag as well as

Foseco Ferrous Foundryman's Handbook

Steel is the most versatile of the structural engineering materials, so that more grades of steel are available for casting than any other alloy type. The casting of steel presents a number of special problems due mainly to the high casting temperature, typically 1550–1600C, and the volume shrinkage that occurs on freezing.

Back to Basics with Ductile Iron Treatment ladles

I've also found that, especially with small deep treatment ladles having a shaped base pocket helps reduce the volume of refractory in the base. If you simply create the pocket in the refractory, you can end up with a large amount of refractory that is doing nothing other than be a pain to remove and require a lot of pre-heating.
