FROM THE PLANNING TO THE MATERIALIZATION OF PLANS INTO THE ACTION: "RIVERSIDE REFRACTORIES & EQUIPMENT INC." COMPANY CARRIES THE TESTS OF THE TAPPING EASE USING BOTH OF DRILLING AND THE ABRASIVE GRINDING DISK

Abstract

Victoria Garten Hüttenindustriebedarf AG accomplished 20 years.

The investigating results carried out by the "Riverside" Company which made a specialty out of taphole mixtures, with regard to the tapping by two methods: one is the drilling and another is the notch breaking by the abrasive grinding disk are given in the article. The development-well success ration dependence on four given testing's parameters was studied: the taphole mixture's development-well success ration in hot state under the load; the drill's degree of penetration into the taphole mixture; the abrasion loss; and the bulk loss of the taphole mixture. Besides, the relationship between alumina content in the taphole mixtures and the development-well success ration was examined. In conclusion the results of the abrasive wear tests were briefl y represented and the summary was made on the proposed tapping methods. Ill. 7. Tab. 1.
