Embodiment 1
[0016] Using the ignition smelting method outside the furnace: according to the conventional steps, the raw materials are dried, the furnace is built, the ingredients are prepared according to the weight percentage, the materials are evenly mixed, the furnace is loaded, smelted, cooled, the furnace is started, weighing, finishing, crushing, magnetic Selection, sampling analysis, packaging.
[0017] Concrete preparation process is as follows:
[0018] 1. Drying of raw materials: Dry raw materials, masonry slag, and batching slag in a drying room at a temperature of 75°C (75±5°C) for no less than 24 hours (24 to 72 hours);
[0019] 2. Weighing raw materials: use batching slag (the slag produced by vanadium-aluminum-chromium-molybdenum alloy smelting) to reduce heat, and the amount of slag added is 0-10% of the total weight of raw materials.
[0020] V 2 o 5 CrO 3 MoO 3 Al CaF 2 Ingredients slag
