Abstract

The invention discloses a slag former which comprises the following raw materials, by weight: 20-30 parts of palygorskite powder, 4-8 parts of fluorite powder, 15-20 parts of talcum powder, 7-10 parts of bentonite powder, 8-11 parts of magnesium carbonate powder, 3-6 parts of quartz powder, 5-9 parts of medical stone powder, 7-12 parts of mineral wool, 3-4 parts of an adhesive and 40-53 parts of water. The fluorite powder, the magnesium carbonate powder, the quartz powder and the medical stone powder in the raw materials of the slag former have a synergistic effect in preparation of the chromium 15 high-chromium cast iron material, and the HRC of the chromium 15 high-chromium cast iron material is synergistically improved.

Description

technical field [0001] The invention belongs to the technical field of refining chromium cast iron, and in particular relates to a slagging agent and its application method in refining high-purity chromium 15 high-chromium cast iron materials. Background technique [0002] Chromium series cast iron materials (including chromium 3 low chromium cast iron materials, chromium 9 medium chromium cast iron materials, chromium 15 high chromium cast iron materials, chromium 26 ultra-high chromium cast iron materials) are one of the wear-resistant materials widely used at home and abroad. [0003] Since the advent of high chromium cast iron wear-resistant materials, it has been considered as an ideal wear-resistant material and is widely used in metallurgy, mining, building materials, electric power, transportation, machinery and other fields. For example, the grinding rings of large crushers, slurry pump impellers, and excavator buckets are all made of high-chromium cast iron wear-re...
