Abstract
The invention relates to an unformed sticky slag-proof flame-resistant material used in steel making. Calculated according to weight percentage, the raw materials include: (1) Forty to seventy percent of bauxite aggregate, (2) Two to ten soft clay, (3) Zero point five to three percent of bentonite, (4) Three to six silicon micro powder, (5) Zero point one to six percent of sodium hexametaphophate, and (6) Zero point one to to one percent of calcium lignosulphonate. The finished product can be produced only by sufficiently and uniformaly stiring the raw materials. The flame-resistant material is characterized in high adhesive rate, high strength, high-temperature resistance and low bonding force with various metallurgical slags. By being sprayed on parts with heavy slags, such as the water-cooling furnace cover of a LF furnace, the fume hood of a converter, a steel ladle, steel slag pot, etc., the flame-resistant material as a coating can avoid the damage on equipment in the course of slag cleaning, thus perfectly protecting the equipment, lowering production cost and increasing the production efficiency of the equipment.
Description
Technical field
The present invention relates to a kind of refractory materials that is applied to high temperature service, particularly, the present invention relates to a kind of anti-sticking slag amorphous refractory material of making steel usefulness.
Background technology
Serious dry slag phenomenon in use usually can appear in equipment such as the water cooled cover of steel-making LF stove, revolving furnace fume hood, ladle, steel slag tank, except needs are often cleared up, distinct issues also are: 1. because slag is firm with stainless steel tube or refractory materials bonding on aforesaid device, thereby scarfing cinder is very difficult, cause maintenance intervals to prolong, thereby ordinary production is affected greatly; 2. since in the scarfing cinder process stainless steel tube or the refractory matter material on the damage equipment very easily, thereby significantly reduced work-ing life of equipment, increased production cost.
Summary of the invention
The objective of the invention is to provides a kind of unshape refractory at the problems referred to above; this refractory materials adhesive rate height, intensity are big, high temperature resistant; little with various metallurgical slag bonding forces; as coating after being sprayed at the serious position of dry slags such as LF stove water cooled cover, revolving furnace fume hood, ladle, steel slag tank; just can avoid the damage that in the scarfing cinder process equipment caused; thereby equipment is played a very good protection, reduced production cost, improved efficiency of equipment.
Concrete technical scheme of the present invention is as follows:
A kind of anti-sticking slag amorphous refractory material is characterized in that by weight percentage, and starting material are formed and comprised: bauxitic clay, soft clay, wilkinite, silicon powder and Sodium hexametaphosphate 99 that adds and calcium lignin sulphonate, and concrete proportioning is as follows:
Bauxitic clay: comprise aggregate and fine powder two portions, wherein aggregate 40～70, fine powder 20～45
