151. In some cases the slag can be disposed of usefully.

152. Pak Nai powder, clay, fire-proof material, slag powder processing tanks.

153. Variation rule of Slag amount during scheelite direct alloying is worked out by theoretical calculation.

154. The slag resistance of magnesia - zircon castable was investigated by crucible test.

155. Resistance to slag relates to the content of magnesia powder and spinel.

156. As to the steel slag, the effect of reducing alkali aggregate reaction is better when alkali reactivity is low and the content of free calcium oxide and periclase is low.

157. Normal magnesia brick is made of Alumina-Magnesia spinel, periclase , It has higher temperature strength, good thermal shock stability, strong resistance to basic slag.

158. Studies of whirlwind furnace show that the processes can be applied to detoxicate the great amount of original chromium slag completely in the industry of chr...

159. The splashed slag density is increased with the increase of top gas flow rate.

160. The abrasive material used may be a synthetic grit a ground slag ground corundum iron or steel shot. It must not contain sand or any form of silica.

161. The slag buildingof RH immersion tube is one of the important factors to effect productivity improvement.

163. Wastes such as industrial slag heaps or city garbage dumps may be more destructive.

164. Burnability of raw meal with selected formula was improved by using copper and zinc tailing and tin slag as raw materials.

165. The influence factors of casting temperature and casting velocity on slag deposition in ingots head were investigated by industrial experiments.

166. The properties of modified slag can be improved by adding suitable amount of invariability agents.

167. Zinc kiln slag contained some valuable and recoverable metals, such as silver, gold, gallium, germanium, etc.

168. Though waste slag amount is not in big volume, it can't be effectively used, therefore the promotion and application of salting-out-extraction process will be inevitably influenced.
