PRODUCTION OF CENTRIFUGALLY CAST SLEEVE

PURPOSE:To prevent the generation of material defects, cracks, etc. and to reduce the cost of production by adding a flux which does not contain B or B compd. to a cast steel contg. C at a specific value or below during or right after pouring of said steel. CONSTITUTION:A molten steel 5 contg. =1.4%...

Beschreibung
Zusammenfassung:	PURPOSE:To prevent the generation of material defects, cracks, etc. and to reduce the cost of production by adding a flux which does not contain B or B compd. to a cast steel contg. C at a specific value or below during or right after pouring of said steel. CONSTITUTION:A molten steel 5 contg. =1.4% C. For example, a flux contg. SiO2+Na2CO3 as an essential component is used as the flux which does not contain B or B compd. The intrusion of B into the cast steel and the generation of the material defects, cracks, etc. are prevented by the above-mentioned method, by which the cost of production is reduced.
